ABSTRACT

Moringa stenopetala (Baker f.) Cufod., is an endemic species growing in the south of Ethiopia. M. stenopetala is often consumed as food and used in traditional medicine and it has also been traditionally used for relieving of pain in Ethiopia. This study aimed to investigate the antinociceptive effect and mechanisms of action of M. stenopetala leaves methanol extract in mice. The per-oral doses of 50, 100, and 200 mg/kg of M. stenopetala extract were tested for antinociceptive action by using hot-plate, tail-immersion, and writhing tests. The possible mechanisms of in the antinociceptive action were investigated by pre-treatment with 5 mg/kg naloxone (non-selective opioid antagonist), 1 mg/kg ketanserin (5-HT2A/2C receptor antagonist), and 1 mg/kg yohimbine (α2 adrenoceptor antagonist). The methanol extract of M. stenopetala showed antinociceptive effect in all tests. The significant involvement of 5-HT2A/2C receptors and α2 adrenoceptors in antinociception induced by M. stenopetala extract in the hot-plate and tail-immersion tests, as well as significant contribution of opioid receptors and α2 adrenoceptors in writhing test, were identified. In conclusion, these findings demonstrate that the methanol extract of M. stenopetala has potential in pain management.

ABSTRACT

Abstract Drawbacks associated with the use of chemical fungicides to control plant pathogenic fungi such as Botrytis cinerea stimulate the need for alternatives. Therefore, the present study was carried out to determine the antifungal potentials of Moringa oleifera extracts against B. cinerea. Phytochemical analysis using qualitative chemical tests revealed the presence of huge amount of crucial phytochemicals compounds like phenolic compounds, alkaloids and saponins in the M. oleifera leaf extract. Antifungal bioassay of the crude extracts indicated better mycelial growth inhibition by methanol leaf extract (99%). The minimum inhibitory concentration (MIC) was 5 mg/ml with 100% spore germination inhibition and minimum fungicidal concentration (MFC) was 10 mg/ml with 98.10% mycelial growth inhibition using broth micro dilution and poisoned food techniques. Gas chromatography-mass spectrometry (GC-MS) analysis led to the identification of 67 volatile chemical compounds in the leaf extract with 6-decenoic acid (Z)- (19.87%) was the predominant compound. Further chemical elucidation of the crude extracts performed by liquid chromatography with tandem mass spectrometry (LC-MS/MS) showed the presence of non-volatile chemical compounds, mostly flavones, flavonoids and phenolic acids (i.e. quercetin and kaempferol). Scanning electron microscopy and transmission electron microscopy analysis showed positive effect of M. oleifera leaf extract on the treated conidia and mycelium of B. cinerea. Findings revealed that irreversible surface and ultra-structural changes with severe detrimental effects on conidia and mycelium morphology compared to control treatment. Overall findings suggested that M. oleifera leaf extract is a promising candidate for biological control of fungal pathogens, thus limiting overdependence on chemical fungicides.


Resumo As desvantagens associadas ao uso de fungicidas químicos para controlar fungos fitopatogênicos, como Botrytis cinerea, estimulam a necessidade de alternativas. Portanto, o presente estudo foi realizado para determinar o potencial antifúngico de extratos de Moringa oleifera contra B. cinerea. A análise fitoquímica usando testes químicos qualitativos revelou a presença de uma grande quantidade de compostos fitoquímicos cruciais, como compostos fenólicos, alcaloides e saponinas no extrato da folha de M. oleifera. O bioensaio antifúngico dos extratos brutos indicou melhor inibição do crescimento micelial pelo extrato de folhas de metanol (99%). A concentração inibitória mínima (MIC) foi de 5 mg/mL com 100% de inibição da germinação de esporos e a concentração fungicida mínima (MFC) foi de 10 mg/mL com 98,10% de inibição do crescimento micelial usando microdiluição em caldo e técnicas de alimentos envenenados. A análise por cromatografia gasosa-espectrometria de massa (GC-MS) levou à identificação de 67 compostos químicos voláteis no extrato da folha, sendo o ácido 6-decenoico (Z) (19,87%) o composto predominante. Elucidação química adicional dos extratos brutos realizada por cromatografia líquida com espectrometria de massa em tandem (LC-MS/MS) mostrou a presença de compostos químicos não voláteis, principalmente flavonas, flavonoides e ácidos fenólicos (ou seja, quercetina e kaempferol). As análises de microscopia eletrônica de varredura e microscopia eletrônica de transmissão mostraram efeito positivo do extrato de folhas de M. oleifera sobre os conídios e micélios tratados de B. cinerea. Os resultados revelaram a superfície irreversível e alterações ultraestruturais com graves efeitos prejudiciais sobre os conídios e a morfologia micelial, em comparação com o tratamento de controle. Os resultados gerais sugeriram que o extrato da folha de M. oleifera é um candidato promissor para o controle biológico de patógenos fúngicos, limitando assim a dependência excessiva de fungicidas químicos.

ABSTRACT

This study aims to evaluate effects of inclusion of moringa in Japanese quail diets on laying performance, egg quality, blood parameters, serum biochemical profile, and behavior. One hundred and forty-four Japanese quails, approximately 35-d-old, were distributed in a completely randomized design with four treatments and six replications. Treatments were diet inclusion of 0, 2, 4 and 6% of dried and ground moringa leaves. The inclusion of moringa in diets reduces the quadratic feed intake up to the level of 1.20%, increases weight of eggs with a quadratic behavior up to 3.80%, and linearly increases yolk weight. Yolk color changes with higher levels of inclusion of moringa and resulted in more intense colors. The biochemical profile of quails changed slightly but remains within the normal range. The inclusion of 4% of moringa in diets increases alkaline phosphatase. Regarding cholesterol and triglycerides, diet with 6% moringa inclusion was lower when compared to the others. The behavior of laying quails does not change due to inclusion of moringa in diets. Up to 3.83% of Moringa oleifera can be included in Japanese quail diet to improve egg quality without compromising performance, biochemical profile, blood parameters and behavior.(AU)


O objetivo deste estudo foi avaliar a inclusão de Moringa oleifera na dieta de codornas japonesas sobre o desempenho, a qualidade de ovos, os parâmetros sanguíneos, o perfil bioquímico e o comportamento. Foram utilizadas 144 codornas japonesas, com aproximadamente 35 dias de idade, as quais foram distribuídas em delineamento inteiramente ao acaso, com quatro tratamentos e seis repetições cada. Foram fornecidas dietas com 0, 2, 4 e 6% de folhas desidratadas e moídas de moringa. A inclusão de moringa nas dietas reduziu quadraticamente o consumo até o nível de 1,2%, aumentou o peso dos ovos com comportamento quadrático até o nível de 3,8% e aumentou linearmente o peso da gema. A coloração da gema se intensificou com maiores inclusões de moringa. O perfil bioquímico sofreu alterações leves, mas não saiu dos padrões normais para codornas. A inclusão de 4% de moringa nas dietas aumentou os níveis de fosfatase alcalina. Já a inclusão de 6% reduziu níveis de colesterol e triglicérides. O comportamento das codornas não se alterou com a inclusão de moringa nas dietas. A inclusão de até 3,83% de Moringa oleifera na dieta de codornas japonesas aumenta a qualidade de ovos sem comprometer o desempenho, o perfil bioquímico, os parâmetros sanguíneos e o comportamento delas.(AU)

ABSTRACT

Objective: Glucocorticoids induced osteoporosis and its related fragility fractures represent a costly human and socioeconomic load worldwide. All the current pharmacological therapies possess multiple adverse effects and high cost. Thus, the pesent study aimed to evaluate the bone healing ability of Moringa oleifera (MO) on glucocorticoids induced osteoporosis in the jawbone of Albino rats. Material and Methods: Osteoporosis was prompted by a daily intraperitoneal injection of 200 µg/ 100 g dexamethasone for 30 days. Next,the animals were randomly divided into 2 groups; osteoporotic and MO treated group. The treated group receivd a daily oral dose of 200mg/kg of MO. Rats from the MO group were sacrificed after 4 weeks from the beginning of treatment, and the same sacrifice date was used for the osteoporotic group. Bone regeneration was evaluated by dual energy x-ray absorptiometry (DEXA), real time polymerase chain reaction (RT-PCR), histopathological and histomorphometric examination. Results: After the sacrifice, the DEXA analysis revealed a significant upregulation in the BMD in the MO treated group (p <0.001). The RT-PCR test showed a significant decline in RANKL gene expression and a significant rise in OPG gene expression in the MO group (p < 0.001, p = 0.002, respectively). The histopathological examination of the MO group displayed a marked healing of the jawbone micro-anatomy. The histomorphometric analysis also showed that the bone area percentage increased significantly in the MO group (p <0.05). Conclusion: A cheap, easy to get, yet a powerful plant like MO leaves, can be cosidered an effective treatment for osteoporosis (AU).


Objetivos: A osteoporose induzida por glicocorticóides e suas fraturas por fragilidade relacionadas representam um custo humano caro e carga socioeconômica em todo o mundo. Todas as terapias farmacológicas atuais possuem múltiplos efeitos adversos e alto custo. Assim, o presente estudo teve como objetivo avaliar a capacidade de cicatrização óssea de Moringa oleifera (MO) em osteoporose induzida na mandíbula de ratos albinos. Material e Métodos: A osteoporose foi induzida por uma injeção intraperitoneal diária de 200 µg / 100 g de dexametasona por 30 dias. A seguir, os animais foram divididos aleatoriamente em 2 grupos; grupo tratado com osteoporose e MO. O grupo tratado recebeu uma diária dose oral de 200 mg / kg de MO. Os ratos do grupo MO foram eutanasiados após 4 semanas do início do tratamento, e a mesma data de eutanásia foi usada para o grupo osteoporótico. A regeneração óssea foi avaliada por espectrometria de raio-x de energia dupla (DEXA), reação em cadeia da polimerase em tempo real (RT-PCR), análise histopatológica e histomorfométrica. Resultados: Após a eutanásia, a análise DEXA revelou uma regulação positiva significativa na DMO no grupo tratado com MO (p <0,001). O teste RT-PCR mostrou um declínio significativo na expressão do gene RANKL e um aumento significativo na expressão do gene OPG no grupo MO (p <0,001, p = 0,002, respectivamente). O exame histopatológico do grupo MO revelou uma cicatrização acentuada da microanatomia do maxilar. A análise histomorfométrica também mostrou aumento significativo na porcentagem de área óssea no grupo MO (p <0,05). Conclusão: A MO é uma planta barata, de fácil obtenção, e suas folhas ainda podem ser consideradas poderosas como tratamento eficaz para a osteoporose. (AU)

ABSTRACT

High fat diet induced hyperlipidemia hamster model was used to explore the anti-hyperlipidemia effect of water extract of Moringa oleifera leaves( WEMOL). On this basis,the possible action mechanism was predicted by network pharmacology. Golden hamsters were randomly divided into normal diet group( NFD),high-fat diet group( HFD),simvastatin group,high dose group of WEMOL( HIWEMOL) and low dose group of WEMOL( LOWEMOL). The model was administered simultaneously for 66 days,during which the body weight changes of hamsters were recorded. At the end of the experiment,serum lipid level and serum transaminase level of golden hamsters in each group were detected,and the pathological changes of liver were observed by hematoxylin-eosin( HE) staining. The results showed that WEMOL could significantly decrease the serum total cholesterol( TC),total triglyceride( TG),low density lipoprotein cholesterol( LDL-c) levels,and reduce the lipid deposition in liver tissue,thus improving the hyperlipidemia of golden hamsters. According to the prediction of network pharmacology,219 targets of potential active components of M.oleifera leaves and 185 targets of water-soluble potential active components of M. oleifera leaves for the treatment of hyperlipidemia were obtained separately. The MCODE analysis was performed on the PPI network of 219 targets and 185 targets obtained above and got five and four clusters respectively. The signaling pathway analysis of clusters showed that among the common pathways,nonalcoholic fatty liver,insulin resistance,MAPK signaling pathway,estrogen signaling pathway,cell apoptosis and HIF-1 signaling pathway were associated with hyperlipidemia. In addition,the potential active components of M. oleifera leaves could also inhibit the metabolic inflammation of hyperlipidemia by modulating complement and coagulation cascades signaling pathway,and GSK3 B,F2,AKT1,RELA,SERPINE1 might be the key targets. The water-soluble potential active components of M. oliefera leaves could modulate lipid metabolism by modulating AMPK signaling pathway and JAK-STAT signaling pathway,with PIK3 CB,PIK3 CA,CASP3,AKT1 and BCL2 as the key targets. These results suggested that WEMOL had anti hyperlipidemia effect,and its mechanism might be related to the protein expression regulation of lipid metabolism,nonalcoholic fatty liver disease and atherosclerosis related signaling pathways.

ABSTRACT

Resumo Fundsamento As sementes de Moringa oleifera , que são utilizadas para clarificação de água, contêm uma lectina chamada WSMoL que tem mostrado atividade antibacteriana e imunomoduladora in vitro . Devido ao seu valor nutritivo e potencial terapêutico, as folhas e as sementes dessa árvore são consumidas em algumas comunidades. Algumas lectinas de plantas não são tóxicas para mamíferos, mas tem sido relatado que outras são prejudiciais quando ingeridas ou administradas por outros meios. Objetivo Como um dos passos necessários para determinar a segurança de WSMoL, nós avaliamos os possíveis efeitos cardiotóxicos desta proteína purificada. Métodos Durante 21 dias consecutivos, a WSMoL foi administrada a camundongos por gavagem. Foram investigadas as funções eletrofisiológicas, mecânicas e metabólicas in vivo e ex vivo por meio de registros eletrocardiográficos, ressonância magnética nuclear e respirometria de alta resolução. Resultados O tratamento com WSMoL não induziu alterações nos níveis de glicose no sangue ou peso corporal em comparação com o grupo controle. Adicionalmente, as relações peso cardíaco/peso corporal e peso cardíaco/comprimento tibial estavam semelhantes em ambos os grupos. A ingestão de lectina também não modificou a tolerância à glicose ou resistência à insulina. Não foram observadas alterações nos parâmetros eletrocardiográficos ou na duração do potencial de ação cardíaco. Os corações dos camundongos dos grupos controle e WSMoL mostraram função ventricular esquerda preservada. Além disso, a WSMoL não induziu alterações na função mitocondrial (em todos os casos, p > 0,05). Conclusões A administração de WSMoL demonstrou ter um perfil de segurança cardíaca. Estes resultados contribuem à avaliação de segurança do uso de sementes de M. oleifera para tratar água, visto que essa lectina está presente na preparação empregada por algumas populações com esse fim.

Abstract Background Moringa oleifera seeds, which are used for water clarification, contain a lectin named WSMoL which has shown in vitro antibacterial and immunomodulatory activity. Due to their nutritional value and therapeutic potential, the leaves and seeds of this tree are eaten in some communities. Some plant lectins are non-toxic to mammals, but others have been reported to be harmful when ingested or administered by other means. Objective As one of the steps needed to define the safety of WSMoL, we evaluated possible cardiotoxic effects of this purified protein. Methods: WSMoL was administered for 21 consecutive days to mice by gavage. Electrophysiological, mechanical, and metabolic cardiac functions were investigated by in vivo and ex vivo electrocardiographic recordings, nuclear magnetic resonance, and high-resolution respirometry. Results The treatment with WSMoL did not induce changes in blood glucose levels or body weight in comparison with control group. Moreover, the heart weight/body weight and heart weight/tibia length ratios were similar in both groups. Lectin ingestion also did not modify glucose tolerance or insulin resistance. No alterations were observed in electrocardiographic parameters or cardiac action potential duration. The heart of mice from the control and WSMoL groups showed preserved left ventricular function. Furthermore, WSMoL did not induce changes in mitochondrial function (in all cases, p > 0.05). Conclusions The administration of WSMoL demonstrated a cardiac safety profile. These results contribute to the safety evaluation of using M. oleifera seeds to treat water, since this lectin is present in the preparation employed by some populations to this end.

ABSTRACT

Introduction: Aluminium, a ubiquitous metal implicated in some neurodegenerative diseases is linked to activation of free oxygen species. The antioxidant-rich plants, Moringa oleifera (MO) is reported to protect against Aluminium activities. This study investigated the actions of MO leaf extract (MOLE) against Aluminium chloride (AlCl3)- induced hippocampal cellular changes and serum levels of alkaline phosphatase (ALP), aspartate transaminase (AST) and alanine transaminase (ALT) in adult Wistar rats.Materials and Methods: Thirty Wistar rats weighing between 150 g and 220 g were grouped (n=5) into; 1-control (5 mL/kg distilled water), 2-AlCl3 (100 mg/kg), 3-low dose MOLE (250 mg/kg), 4-high dose MOLE (1,000 mg/kg), 5-concurrent AlCl3 and low dose MOLE, and 6-concurrent AlCl3 and high dose MOLE. All administrations were by oral gavages for 21 days. On day 22, following deep anaesthesia and cardiac puncture, blood was obtained for serum enzyme analysis, and the brain perfusion fixed, harvested and processed for histological study.Results: Results showed significantly (p < 0.05) higher ALP level in the AlCl3 group compared with the control, as well as the other test groups. However, there was no significant (p > 0.05) AST and ALT levels. The hippocampal CA3 of the AlCl3 group showed hypertrophic cells, with some of the cells having karyorrhectic features. The concurrent AlCl3 and low and high doses, MOLE groups showed less of these adverse features.Conclusion: These results suggest that MOLE may protect enzymatic activities against Aluminium chloride. However, its action on hippocampus is still subject to further investigation.


Introducción: El aluminio, un metal presente en diversos lugares implicado en algunas enfermedades neurodegenerativas, está relacionado con la activación de especies reactivas de oxígeno. Se informa que las plantas ricas en antioxidantes, Moringa oleifera (MO) protegen contra la acción del aluminio. Este estudio investigó las acciones del extracto de hoja de MO (MOLE) en los cambios celulares del hipocampo inducidos por el cloruro de aluminio (AlCl3) y los niveles séricos de fosfatasa alcalina (ALP), aspartato transaminasa (AST) y alanina transaminasa (ALT) en ratas Wistar adultas.Materiales y métodos: SE utilizaron treinta ratas Wistar divididas en 5 grupos, los animales pesaban entre 150 gy 220 g; 1 control (5 ml / kg de agua destilada), 2-AlCl3 (100 mg / kg), 3 MOLE de dosis baja (250 mg / kg), 4 MOLE de dosis alta (1000 mg / kg), 5 AlCl3 concurrente y MOLE de dosis baja, y MOLE 6-concurrente y MOLE de dosis alta. Todas las administraciones fueron por sonda oral durante 21 días. El día 22, después de la anestesia profunda y la punción cardíaca, se obtuvo sangre para el análisis de las enzimas séricas y la perfusión cerebral se fijó, recogió y procesó para el estudio histológico.Resultados: Los resultados mostraron un nivel de ALP significativamente (p <0.05) más alto en el grupo AlCl3 en comparación con el control, así como en los otros grupos de prueba. Sin embargo, no hubo niveles significativos (p> 0.05) de AST y ALT. El hipocampo CA3 del grupo AlCl3 mostró células hipertróficas, y algunas de las células tenían características cariorrecticas. Los grupos de AlCl3 concurrentes y dosis bajas y altas, MOLE mostraron menos de estas características adversas.Conclusión: Estos resultados sugieren que MOLE puede proteger las actividades enzimáticas contra el cloruro de aluminio. Sin embargo, su acción sobre el hipocampo aún está sujeta a más investigaciones.

ABSTRACT

Worldwide, iron deficiency anaemia (IDA) is one the most significant nutritional maladies, especially in low and middle-income countries. This is mainly due to the associated morbidity, economic implications on the health system and the welfare state. One of the most prevalent causes of IDA in children is insufficient food intake, which has an obvious connection with the social environment. The main strategy in the management of this condition is counteracting such deficiency through the improvement of nutrition and family upbringing. Aiming to explore affordable, novel and straightforward approaches to treat this nutritional condition, we developed a descriptive study associated with the incorporation of Moringa Oleifera in homemade fruit beverages delivered to 32 children from low-income families, in order to assess the evolution of IDA, evaluating specific clinical parameters such as red blood cells volume, as well as hemoglobin, ferritin and serum iron levels, within a two months lapse. At the end of this period, we observed a significant statistical rise in the levels of all the assessed parameters, finding about a 1.3-fold increase in hemoglobin and ferritin levels and in red blood cells volume; serum iron was 1.1 times higher. These findings are demonstrative of the wide spectrum of the medicinal features of Moringa and establish a promising and accessible strategy easy to incorporate into the diet of families of children suffering this pathology(AU)


La anemia ferropénica (AF) es una de las carencias nutricionales más significativas a nivel mundial, especialmente en los países de bajos y medios ingresos, debido principalmente a la morbilidad asociada, las implicaciones en el sistema de salud y el estado de bienestar. Una de las causas más frecuentes de esta deficiencia en los niños es la ingesta insuficiente, que tiene una evidente conexión con el entorno social. La principal estrategia en el manejo de esta afección es contrarrestar esta deficiencia a través de la mejora de la nutrición y la educación familiar. Con el objetivo de explorar enfoques asequibles, novedosos y directos para el tratamiento de esta enfermedad, se desarrolló un estudio descriptivo asociado a la incorporación de la Moringa Oleifera en bebidas de frutas caseras que se suministraron a 32 niños de familias de bajos ingresos para hacerle seguimiento a la evolución de la anemia por deficiencia de hierro, evaluando parámetros clínicos específicos como el volumen de células rojas y los niveles de hemoglobina, ferritina y hierro sérico en un lapso de dos meses. Se observó un aumento estadísticamente significativo en los niveles de todos los parámetros evaluados una vez finalizado el período de intervención. Al final del ensayo, observamos un aumento estadístico significativo en los niveles de todos los parámetros evaluados, encontrando un aumento de aproximadamente 1.3 veces en los niveles de hemoglobina y ferritina y en el volumen de los glóbulos rojos; el hierro sérico fue 1.1 veces mayor. Estos hallazgos son una demostración del amplio espectro de las características medicinales de la Moringa y establecen una estrategia prometedora y accesible, fácil de incorporar a la dieta de las familias de los niños que sufren esta patología(AU)

ABSTRACT

BACKGROUND/OBJECTIVES: The leaves of Moringa oleifera (MO) and Moringa stenopetala (MS) commonly grown in Ethiopia possess potential nutritional and medicinal value. The aim of this study was to evaluate the nutritional and functional characteristics of the dried leaf powder from two Moringa species to develop sustainable nutritional supplements for Ethiopians from locally grown plant sources. SUBJECTS/METHODS: Freshly harvested and air-dried MO and MS leaves were authenticated and the nutritional contents, such as protein, ash, lipids, and selected vitamins and minerals, were analyzed using standard analytical procedures. Amino acid compositions were also determined by an amino acid analyzer. Nine-week-old mice were randomly divided into four groups to investigate the anti-obesity effects of Moringa. The first group was fed a basal diet, the second group a high-fat diet, and the others were fed a high-fat diet containing 0.1% Moringa leaf powder from each species. After seven weeks, serum indices related to lipid profiles from each mouse were analyzed. RESULTS: The present study revealed high protein (28–29%) and ash (7–11%) contents. Glutamic acid, aspartic acid, proline, and leucine were the most abundantly found amino acids in both species. The predominant minerals in the leaf powder were calcium (826–1,530 mg/100 g), potassium (794–904 mg/100 g), and magnesium (286-431 mg/100 g). Pyridoxine (475.06 mg/100 g) and vitamin E (34.2 mg/100 g) were found only in MS. Niacin was found only in MO at 32.21 mg/100 g, whereas ascorbic acid was found in both species (3.89 and 6.19 mg/100 g dry weight for MO and MS, respectively). The results of the animal study showed that mice on a high-fat diet containing 0.1% MO leaf powder alleviated the elevation of cholesterol, triglycerides, and low-density lipoprotein cholesterol induced by the high fat diet. MO was more effective than MS in preventing hypercholesterolemia and fat deposition. CONCLUSIONS: The findings in this work confirmed that Moringa leaves of both MO and MS possessed high nutritional value but MO was better at preventing the harmful effects of the high-fat diet than MS.

ABSTRACT

Moringa leaves and spinach used as vegetables containing cyanogens and polyphenols having suspected antithyroidal activity; however, detailed studies in this aspect found unavailable. Goitrogenic/antithyroid potentiality of those plant foods of Indian origin was evaluated. To explore the goitrogenic/antithyroid effect of those plant foods cyanogenic glucosides, glucosinolates, thiocyanate and polyphenol content were measured. These plant foods were fed with diet regularly to adult male albino rats for 30 and 60 days respectively, followed by evaluation of morphological and functional status of thyroid,as thyroid gland weight, the activity status of thyroid hormone synthesizing enzymes viz. TPO, Na+-K+-ATPase, deiodinase I, thyroid hormone profiles, thyroid histoarchitecture as well as urinary iodine and thiocyanate. In moringa leaves and spinach fed diet, there was a significant increase in urinary excretion of thiocyanate and iodine, enlargement of thyroid gland along with hypertrophy of thyroid follicles and altered in the activities of thyroid hormone synthesizing enzymes with concomitant changes of thyroid hormone profiles. Effects were more severe in moringa leaves treated group than that of spinach. Biochemical analysis moringa leaves and spinach reveal that those are rich sources of goitrogens and their prolonged consumption gradually developed a relative state of biochemical and morphological hypothyroidism.

ABSTRACT

Abstract Purpose: To evaluate if Moringa oleifera leaf aqueous extract (ME) influences the healing of skin wounds of diabetic rats. Methods: Wistar rats were used (6 rats/group). Group 1 received normal saline (NS) v.o. Group 2 received moringa extract (100mg/kg v.o) for 3 weeks. Groups 3 and 4: Streptozotocin (STZ) induced diabetes. Group 3 received NS; Group 4 received aqueous ME (100mg/kg) v.o.The wounds of groups 1 and 3 rats were topically treated with NS; wounds of groups 2 and 4 treated with 200µL of 10% ME. After anesthesia, all rats had skin square excision wounds 1.5cm2. Wound percent contractions were measured. On 10th day, blood glucose and serum cytokines were measured. Histometry of wounds was studied using ImagePro6.0 software. Results: Glycemia was significantly reduced in ME treated rats. These rats had higher percent contraction of the wounds on 2nd, 5th and 10th days, then controls (p<0.05). Diabetic rats treated with NS had TNF-α, IL-1β and IL-6 expression higher than in rats receiving ME. The histopathological score of ME treated diabetic rats (198±13.7) was significantly higher than treatment with NS (145±10.5). Conclusion: ME extract positively influenced healing of wounds in diabetic rats after systemic and topical treatment.

ABSTRACT

Moringa oleifera Lam. (Moringaceae) is a plant with several biological activities and therapeutic properties. However, the complete knowledge about its pharmacological, biological and ecological effects, and about the active components present in each vegetable part are not still completely elucidated. This study aimed to evaluate the antioxidant and photoprotective activities of different extracts from leaves and flowers of M. oleifera. These activities were assessed through in vitro tests, DPPH radical scavenging method, iron ion chelating effect (FRAP), lipid peroxidation (TBARS), nitric oxide scavenging method and assessment of the activity against the lipid peroxidation through hemolytic method. The photoprotective activity was assessed through spectrophotometric analysis and through in vitro test with Labsphere. It was also determined the extract's phenolic content and total flavonoid through spectrophotometry and HPLC. The obtained results demonstrated that this species have components with antioxidant and photoprotective potential mainly in the extracts obtained from fresh leaves and flowers. Therefore, it was possible to verify that M. oleifera has potential to be used as source of antioxidant components with photoprotective activity mainly due to the presence of phenolic components and among these, the flavonoids.

ABSTRACT

This study aims to establish the characteristic fingerprint of the leaves of Moringa oleifera by Ultra High Performance Liquid Chromatography (UPLC) for its quality control. The method was developed on a column of Agilent Eclipse XDB-C₁₈ with acetonitrile-0.01% TFA solution as the mobile phase by gradient elution at a flow rate of 0.5 mL·min⁻¹. The detective wavelength was 210 nm, and the column temperature was 35 °C. The 14 batches of the leaves of M. oleifera were compared for the similarity by using Traditional Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System (2004A). The UPLC characteristic fingerprint was established, and twelve common peaks were identified by comparison with the references and UPLC-MS. The relative retention times were 0.08 (No. 1, adenosine), 0.14 (No. 2, L-phenylalanine), 0.22 (No. 3, 5-caffeoylquinic acid), 0.28 (No. 4, L-tryptophane), 0.42 (No. 5, 4-caffeoylquinic acid), 0.65 (No. 6, vicenin-2), 0.94 (No. 7, vitexin), 0.96 (No. 8, isovitexin), 1.00 (No. 9, isoquercitrin), 1.11 [No. 10, quercetin 3-O-β-D-(6"-malonyl)-glucopyranoside], 1.21 (No. 11, astragalin) and 1.37 [No. 12, kaempferol 3-O-β-D-(6"-malonyl)-glucopyranoside]. It is the first time to establish the UPLC characteristic fingerprint of the leaves of M. oleifera. The method is simple, quick and reproducible with high precision, which can provide a scientific basis for the quality control of the leaves of M. oleifera.

ABSTRACT

Moringa oleifera (LAM), arbre tropical à usages multiples, constitue de nos jours une nouvelle ressource alimentaire et économique pour les pays du Sud. Ces feuilles sont faciles d'accès et très riches en protéines, en vitamines et en minéraux. Elles sont de plus en plus utilisées dans des projets luttant contre la malnutrition. Cependant, le goût, la présentation et la qualité de ces produits demeurent une préoccupation majeure nécessitant des adaptations innovantes. L'objectif de cette étude était d'étudier la comprimabilité des poudres de feuilles de Moringa oleifera en améliorant le goût avec des matières premières locales et facilement accessibles comme la poudre de pulpe de Andansonia digitata. Les propriétés physico-chimiques et les tests pharmacotechniques ont permis de contrôler la qualité des poudres, des comprimés et orienter le choix du procédé de fabrication. Cinq (5) types de formulations (F1 à F5) ont été réalisés et les comprimés ont été fabriqués par compression après granulation par la voie sèche. Les comprimés des formulations F4 et F5 ont donné de meilleures propriétés pharmacotechniques selon les recommandations de la pharmacopée Européenne 6.0. L'association des deux poudres offre une alternative pour la fabrication de comprimés à croquer avec un goût acceptable

ABSTRACT

Diet and nutrition are important factors in the promotion and maintenance of good health throughout the entire life course. A plant-based diet may be able to prevent and treat chronic diseases such as diabetes, heart disease and hypertension, obesity, chronic inflammation and cancer. Phytonutrient rich foods are found in traditional African diet which is mostly vegetarian, and most of these food plants are often used for medicinal purposes. This review focuses on a peculiar plant Moringa oleifera, called the "Miracle Tree", considered to be one of nature's healthiest and most nutritious foods. Countless studies describe the benefits of Moringa leaves, pods, seeds and flowers. Its well-documented role in prevention and treatment of chronic diseases is hypothesized here as a result of possible of cross-kingdom regulation by exogenous vegetal microRNAs and synergistic action of plant bioactive components on endogenous human microRNA regulation. The potential health impact of phytocomplexes from African dietary plants within the context of cross-kingdom and endogenous microRNA regulation on health improvement and the overall economic well-being of the continent is estimated to be enormous

ABSTRACT

La hoja de moringa era ya empleada en la medicina ayurvédica hace cientos de años y conocida por egipcios y romanos por su uso cosmético. Moringa oleifera es una de las 13 especies de único género que compone la familia Moringáceas. Originaria del norte de la India, Nepal y NO de Pakistán, actualmente está extendida por la franja intertropical de todo el mundo. Son árboles de hasta 12 m de altura, hojas varias veces pinnadas, flores en panículas, zigomorfas, pentámeras, bisexuales, fruto tipo cápsula y semillas oleaginosas con tres alas. Se cultiva para obtener forraje para el ganado y usos alimenticos (hojas, pericarpio del fruto y aceite de semillas). Los requerimientos del cultivo son poco exigentes en cuanto a suelos y cantidad de agua, siendo la temperatura el principal factor limitante. Sus hojas son muy ricas en proteínas, aminoácidos azufrados (metionina y cisteína) y lisina. Son también ricas en calcio y hierro. En las hojas aparecen una extensa variedad de antioxidantes (polifenoles, flavonoides, ácidos fenólicos) y glucosinolatos. El aceite de semilla contiene un alto contenido en ácido oleico (70 %), menos del 1 % de poliinsaturados y 6,7 % de ácido behénico. Estas propiedades hacen que diferentes partes de la planta se usen o potencialmente puedan usarse en: cosmética, industria farmacéutica, descontaminación de agua, producción de biodiesel, lucha biológica contra hongos y plagas agrícolas, alimentación animal y usos medicinales. En alimentación humana se emplea como suplemento alimentario para obtener proteínas de alto valor biológico o paliar déficits de calcio en poblaciones sometidas a infraalimentación. Sus usos medicinales son bien conocidos en sistemas médicos tradicionales, si bien no están avalados por ensayos de laboratorios y ensayos clínicos. En la actualidad se llevan a cabo cuantiosos experimentos científicos para evaluar la eficacia terapéutica de la planta y su posible toxicidad. Se demostró el poder hipoglucemiante e hipolipemiante. Además, en ensayos in vitro e in vivo se está poniendo de manifiesto su posible valor antitumoral. Se sugiere seguir ahondando en el estudio de todas sus posibilidades. (AU)

ABSTRACT

Objetivou-se determinar os valores energéticos e nutricionais das folhas de Moringa oleifera (MOL) para frangos de corte. Utilizaram-se 90 pintos machos, Cobb-500, com 14 dias de idade, distribuídos em delineamento inteiramente ao acaso, com cinco tratamentos e seis repetições de três aves. Os tratamentos consistiram de: uma dieta referência e quatro dietas com substituição de 10%, 20%, 30% e 40% da dieta referência pelas folhas de MOL. O período experimental teve duração de oito dias, utilizando-se a metodologia de coleta total de excretas. Foram determinados os valores de energia metabolizável aparente (EMA), aparente corrigida para o nitrogênio (EMAn), coeficiente de metabolizabilidade aparente da matéria seca (CMAMS), da proteína bruta (CMAPB) e da energia bruta (CMAEB). Os resultados obtidos foram submetidos à análise de variância e à análise de regressão a 5% de probabilidade. Houve efeito quadrático das variáveis à medida que a moringa era adicionada à ração referência. Na derivação das equações de regressão, o nível que proporcionou os melhores valores de EMA, EMAn e CMEB foi de 37,7% de substituição. O farelo de folhas MOL apresentou médias de 3140kcal/kg de EMA, 2845kcal/kg de EMAn, 76,92% de CMAEB, 76,63% de CMAMS e 73,42% de CMAPB.(AU)


This study aimed to determine the energy and nutritional value of the leaves of Moringa oleifera (MOL) for broilers. We used 90 male chicks, Cobb-500, with 14 days of age in a completely randomized design with five treatments and six repetitions of three birds. The treatments were: reference diet and 4 diets with substitution of 10%, 20%, 30%, and 40% of the diet by reference sheet MOL. The trial lasted eight days, using the method of total excreta collection. The apparent metabolizable energy (AME), apparent corrected for nitrogen (AMEn), apparent metabolizable coefficient of dry matter (AMCDM), crude protein (AMCCP) and gross energy (AMCGE). The results were submitted to analysis of variance and regression analysis at 5% probability. There was a quadratic effect of the variables as the moringa was added to the reference diet. In the derivation of the regression equations the level that provided the best values of AME, AMEn, AMCGE was 37.7% substitution. The leaves meal MOL presented average 3140kcal / kg of AME, 2845kcal / kg AMEn, 76.92% of AMCGE, 76.63% of AMCDM and 73.42% of AMCCP.(AU)
