ABSTRACT
Introducción: La preeclampsia es una afectación multisistémica que contribuye a la morbilidad y mortalidad materna junto con importantes complicaciones fetales. Dado que se ha observado que el consumo de frutas y vegetales posee un efecto beneficioso en la reducción del riesgo de enfermedades cardiovasculares, el consumo de estos alimentos también podría reducir el riesgo de desarrollo de preeclampsia en la mujer embarazada. Objetivo: Analizar el impacto del consumo de frutas y vegetales en el riesgo de desarrollo de preeclampsia en la mujer embarazada. Metodología: Se ha realizado una revisión sistemática siguiendo la metodología PRISMA. Las bases de datos utilizadas fueron Scopus, Pubmed y Web of Science. Se han incluido artículos publicados en los últimos cinco años, escritos en inglés o español y de acceso gratuito. La calidad metodológica se evaluó mediante la escala de STROBE y MINCIR. Resultados: Se han seleccionado nueve artículos para dar respuesta al objetivo planteado. El porcentaje de gestantes con un patrón dietético basado en frutas y vegetales que desarrolla preeclampsia es relativamente bajo, oscilando entre el 7 y el 8,8%. Así mismo, la mayoría de los estudios seleccionados muestran que la ingesta de frutas y vegetales tiene un efecto protector en el desarrollo de preeclampsia y, que este efecto protector es directamente proporcional al número de raciones consumidas de estos alimentos. Conclusiones: La literatura disponible para analizar el impacto que tiene el consumo de frutas y vegetales en el riesgo de desarrollo de preeclampsia es muy limitada. Por ello, se insta a realizar más investigaciones sobre este tema para poder aportar unos resultados más robustos.
Introduction: Preeclampsia is a multisystem affectation that contributes to maternal morbidity and mortality along with important fetal complications. Since it has been observed that the consumption of fruits and vegetables has a beneficial effect in reducing the risk of cardiovascular diseases, the consumption of these foods could also reduce the risk and development of preeclampsia in pregnant women. Objective: To analyze the impact of fruit and vegetable consumption on the risk of development of preeclampsia in pregnant women. Methodology: A systematic review has been carried out following the PRISMA methodology. The databases used were Scopus, Pubmed and Web of Science. Articles published in the last five years, written in English or Spanish and with free access have been included. Methodological quality was assessed using the STROBE and MINCIR scales. Results: There have been selected nine articles to provide a response to the proposed objective. The percentage of pregnant women with a dietary pattern based on fruits and vegetables who develop preeclampsia is relatively low, ranging between 7 and 8.8%. Likewise, most of the selected studies show that the intake of fruits and vegetables has a protective effect on the development of preeclampsia and that this protective effect is directly proportional to the number of servings consumed of these foods. Conclusions: The literature available to analyze the impact that fruit and vegetable consumption has on the risk and development of preeclampsia is very limited. Therefore, more research on this topic is urged to provide more robust results.
ABSTRACT
Background: The provision of adequate nutrition is of the utmost importance for the promotion of optimal growth and development in the early stages of human life as well as the stimulation of immune system function to combat infections. Therefore, this study aimed to assess the level of consumption and the factors affecting the provision of fruits and vegetables to children in Bayelsa state of Nigeria. Methods: This was a population-based survey conducted among 360 parents/caregivers of children aged 5 years and below randomly selected from Bayelsa state, Nigeria. The data for this study was collected with in-person interviews utilizing a standardized questionnaire. The results were presented in frequency and percentage. The level of significance was determined using a confidence interval of 95% and p<0.05. Results: Most of the respondents 355 (98.6%) were female with the age range 25-44 making 86.65% of the total population. Findings show that 40.8% of respondents gave their children fruits and vegetables only once a week while 3.6% gave their children fruits and vegetables 4 times and above a week. The majority of respondents 240 (66.7%) indicated that the high cost of fruits and vegetables was the main factor that affected consumption of fruits and vegetables. Conclusions: The findings demonstrated a low consumption level of fruits and vegetables among the children in Bayelsa state. Therefore, health professionals should be obliged to educate parents and caregivers of children on adequate provision of fruits and vegetables for their children.
ABSTRACT
Abstract Understanding morphological and physiological changes under different light conditions in native fruit species in juveniles' stage is important, as it indicate the appropriate environment to achieve vigorous saplings. We aimed to verify growth and morphophysiological changes under shade gradient in feijoa (Acca sellowiana (O. Berg) Burret) to achieve good quality saplings adequate to improve cultivation in orchards. The saplings were grown for twenty-one-month under four shading treatments (0%, 30%, 50%, and 80%). Growth, photosynthetic pigments, gas exchanges, chlorophyll fluorescence, and leaf anatomy parameters were evaluated. Saplings under full sun and 30% shade had higher height and diameter growth and dry mass accumulation due to higher photosynthesis rate. As main acclimatization mechanisms in feijoa saplings under 80% shade were developed larger leaf area, reduced leaf blade thickness, and enhanced quantum yield of photosystem II. Even so, the net CO2 assimilation and the electron transport rate was lower and, consequently, there was a restriction on the growth and dry mass in saplings under deep shade. Therefore, to obtain higher quality feijoa saplings, we recommend that it be carried out in full sun or up to 30% shade, to maximize the sapling vigor in nurseries and, later, this light environment can also be used in orchards for favor growth and fruit production.
Resumo A verificação de mudanças morfológicas e fisiológicas sob diferentes condições luminosas em espécies frutíferas nativas em estágio juvenil é importante, uma vez que indicam o ambiente adequado para a formação de mudas com alto vigor. Objetivou-se verificar o crescimento e as alterações morfofisiológicas sob gradiente de sombreamento em mudas de feijoa (Acca sellowiana (O. Berg) Burret) para obter mudas de boa qualidade, adequadas para fomentar os plantios da espécie em pomares. As mudas foram cultivadas por vinte e um meses sob quatro tratamentos de sombreamento (0%, 30%, 50% e 80%). Foram avaliados parâmetros de crescimento, pigmentos fotossintéticos, trocas gasosas, fluorescência da clorofila e anatomia foliar. Mudas a pleno sol e 30% de sombra apresentaram maior crescimento em altura, diâmetro e acúmulo de massa seca, devido à maior taxa de fotossíntese. Como principais mecanismos de aclimatação sob 80% de sombra, as mudas desenvolveram maior área foliar, redução da espessura do limbo foliar e aumento do rendimento quântico do fotossistema II. Mesmo assim, a assimilação líquida de CO2 e a taxa de transporte de elétrons foram menores e, consequentemente, houve restrição ao crescimento e acúmulo de massa seca das mudas no maior nível de sombreamento. Portanto, para a obtenção de mudas de feijoa de maior qualidade, recomendamos que seja realizada a pleno sol ou até 30% de sombra, para maximizar o vigor das mudas em viveiros e, posteriormente, este ambiente de luz também pode ser utilizado em pomares para favorecer o crescimento e a produção de frutos.

Abstract Responses of three tomato (Lycopersicon esculentum Mill.) hybrids viz. 'Luanova', 'Savarona' and 'Tessera' to various doses (0, 0.5, 1.0, 1.5 and 2.0 g L-1) of soil application of humic acid (HA) were evaluated in terms of plant growth, productivity and quality of fruits, under greenhouse conditions, during 2011-12 and 2012-13. In addition to improved quality characteristics, higher values for yield and yield components were recorded for tomato fruits harvested from plants of 'Tessera' cultivar compared to those harvested from other hybrids tested, regardless of growing seasons. Plants from 'Luanova' cultivar were, however, earlier in fruiting with higher number of fruits per plant. Soil application of HA presented positive effects on yield and physicochemical quality of tomato fruits irrespective of the dose of HA and the cultivar investigated, in both seasons. Soil application of HA at higher dose 1.5 g L-1 exhibited better results in all the three tomato cultivars tested, in terms of their vegetative and reproductive growth, and significantly improved the physicochemical quality of their fruits. Conclusively, the tomato hybrid 'Tessera' was found suitable for cultivation under greenhouse conditions while soil application of aqueous solution of HA @ 1.5 g L-1 substantially resulted in higher production of quality tomato fruits.
Resumo Respostas de três híbridos de tomate (Lycopersicon esculentum Mill.) viz. 'Luanova', 'Savarona' e 'Tessera' para várias doses (0, 0,5, 1,0, 1,5 e 2,0 g L-1) de aplicação de ácido húmico (AH) no solo foram avaliadas em termos de crescimento da planta, produtividade e qualidade de frutas, em casa de vegetação, durante 2011-12 e 2012-13. Além das características de qualidade melhoradas, valores mais elevados para o rendimento e os componentes do rendimento foram registrados para frutos de tomate colhidos de plantas do cultivar 'Tessera' em comparação com aqueles colhidos de outros híbridos testados, independentemente das estações de cultivo. As plantas do cultivar 'Luanova', no entanto, frutificaram mais cedo com maior número de frutos por planta. A aplicação de AH no solo apresentou efeitos positivos sobre a produtividade e a qualidade físico-química dos frutos de tomate, independentemente da dose de AH e do cultivar investigado, nas duas safras. A aplicação de HA no solo na dose maior de 1,5 g L-1 apresentou melhores resultados nos três cultivares de tomate testados, quanto ao crescimento vegetativo e reprodutivo, e melhorou significativamente a qualidade físico-química dos frutos. Conclusivamente, o híbrido de tomate 'Tessera' foi considerado adequado para cultivo em casa de vegetação, enquanto a aplicação no solo de solução aquosa de HA @ 1,5 g L-1 resultou substancialmente em maior produção de frutos de tomate de qualidade.

ABSTRACT
The study was conducted in Vijayapura district of Karnataka during 2019-20 to analyse the constraints and suggestions of fruit crop growers. Forty each grape, lime and pomegranate growers were selected by use of simple random sampling technique. Thus, making a total sample size of 120. Personal interview method was used to collect data and appropriate statistical tools were applied to analyse the data. The findings revealed that, with respect to the constraints faced by fruit crop growers in fruit crop production, production constraints were lack of irrigation facilities (87.50%) followed by high cost of inputs (73.33%). Major financial constraints were non-availability of credit at right time (73.33%) followed by inadequate credit (70.83%). High wages (70.00%) and non-availability of labourer (61.67%) were the main issues relating to labour constraints. Regarding marketing constraints, fluctuating price (87.17%) followed by delayed cash payment and exploitation by middlemen (77.50%) were the major constraints. The suggestions offered by the fruit crop growers are provision for irrigation facility (85.00%) followed by provision of timely and adequate market information (76.67%), protection from exploitation by middlemen (75.00%). Provision for suitable market infrastructure, timely and adequate credit, timely and adequate cash payment, continuous power supply, interest free credit and longer repayment period for credit were other suggestions offered to improve the returns from fruit crop cultivation.
ABSTRACT
Objective: Explore the association between compliance with recommended consumption (5-a-day) of fruits and vegetables (F&V) with sociodemographic factors of university students of Latin America. Subjects: We conducted an analytical cross-sectional study in which 4,880 university students from 10 Latin American countries completed a self-administered online survey. Methods: F&V consumption and other sociodemographic variables were measured according to a validated survey. Body mass index was self-reported. Ordinal logistic regression models were applied. Results: Regarding the consumption of F&V, 4.7% of men complied with the recommendation, while in women this value reached 7.7%. In the adjusted model, having a normal weight (OR= 0.59; 95% CI 0.44-0.7; p=<0.001), being female (OR= 0.67; 95% CI 0.49-0.89; p=<0.01), being enrolled in a health-related degree program (OR= 0,60; IC95% 0,45-0,78; p<0.001), having professional parents (OR= 0.75; 95% CI 0.60-0.95; p=<0.05) and practicing physical activity (OR= 0.34; 95% CI 0.27-0.42; p=<0.001) were associated with compliance to F&V consumption recommendations. In the analysis by country, physical activity was the variable most associated with F&V consumption. Conclusion: We observed a low consumption of F&V in university students. The variables associated with compliance to the F&V recommendation were being normal weight, female, being enrolled in a health-related degree program, having professional parents, and practicing physical activity, the latter being the most important variable.

ABSTRACT
Fruits are classified as perishable agricultural commodities. When fruits are harvested prematurely or when they are overripe, their storage life is shortened and their quality deteriorates. Therefore, it is important to harvest fruits at the appropriate stage of maturity in order to ensure good quality and better storage. Nevertheless, the inadequate implementation of proper handling techniques for agricultural produce has led to a significant occurrence of post-harvest losses, resulting in the wastage of valuable resources such as time and financial investments. The lack of appropriate handling procedures and chemical treatment methods are leading to significant losses in commodities. Therefore, it can be deduced that producers are currently experiencing significant economic detriment as a result of inadequate handling techniques, insufficient understanding of the underlying factors contributing to postharvest loss, and a dearth of effective preservation methodologies. However, the mitigation of loss can be achieved through the implementation of appropriate management and handling procedures. This review focuses on various aspects of post-harvest handling methods for preservation of fruits for longer time for processing and value addition.
ABSTRACT
The issue of post-harvest deterioration in fruits and vegetables constitutes a critical concern, especially given the rising global food security challenges. The aim of this review article is to present a comprehensive examination of the diverse facets contributing to the deterioration of these valuable food resources, ranging from biological and environmental factors to economic implications and current preservation methods. One area of focus involves scrutinizing the gaps in the current body of knowledge, particularly the intricate molecular mechanisms governing enzymatic activity and microbial spoilage. Recent developments in technology also present intriguing possibilities for future research. Artificial Intelligence (AI) offers transformative potential in monitoring the quality of stored produce by predicting the onset of spoilage using complex algorithms. This work also delves into the prospects of employing the Internet of Things (IoT) for real-time assessment and control of storage conditions, which could revolutionize supply chain management and significantly minimize deterioration during transport. Another exciting avenue lies in the utilization of novel packaging materials especially those which are biodegradable and may be imbued with natural preservatives, a move that aligns well with global sustainability goals. Any such technological advancements must be scrutinized in the context of existing food safety standards and regulations, both at the national and international levels. These standards govern everything from permissible microbial activity levels to waste management, and are dictated by organizations such as the FDA and EFSA, as well as international frameworks like the Codex Alimentarius.
ABSTRACT
Background: Five servings of fruits and vegetables each day, along with relatively unprocessed whole grains or legumes with each meal, are essential for reducing the risk of obesity, hypertension and other related non communicable diseases. While being low or relatively low in calories, fruits and vegetables include a large amount of dietary fiber and a range of micronutrients, antioxidants and phytochemicals which are all essential for health. Aims: To investigate the intake of fruits and vegetables as self prescribed weight reducing and DASH (Dietary Approach to Stop Hypertension) diets among obese - hypertensive individuals attending Irrua Specialist Teaching Hospital Irrua, Edo State. Methods: A descriptive cross sectional study design was used with a sample size of 440 obese hypertensive individuals (with body mass index of = or > 30Kg/m2 and blood pressure of = or > 140/90mmHg). Questionnaires, personal interviews and anthropometric measurements were used to collect data using purposive sampling technique. Data collected were analyzed using Statistical Package for the Social Sciences (IBM SPSS) 22 Version. Results: A total of 440 respondents were used in the study and data were elicited from all of this number giving a 100% response rate. A total of 242 (55.0%) and 215 (48.9%) of the respondents consumed fruits and vegetables only one to two days per week with only 36 (8.2%) and 26 (5.9%) consuming fruits and vegetables every day. Conclusion: It can be concluded based on the key findings of this study that there is statistically significant mean difference in fruits and vegetables consumption amongst obese - hypertensive individuals attending Irrua Specialist Teaching Hospital, Edo State, Nigeria (p<0.05).
ABSTRACT
Introducción: el consumo de frutas y verduras como proceso protector de la salud se ha analizado principalmente desde la perspectiva de los estilos de vida individuales; sin embargo, procesos de tipo estructural como los modelos de producción de alimentos y las políticas de alimentación determinan su producción, disponibilidad y acceso. Se planteó como objetivo analizar los procesos de determinación social del con- sumo de frutas y verduras en el municipio de Florida (Valle del Cauca, Colombia). Materiales y métodos: estudio cualitativo, tipo estudio de caso, con enfoque de determinación social. Incluyó revisión documental de políticas alimentarias y grupos de discusión con actores clave; el análisis de contenido permitió explicitar mensajes y discursos. Resultados: en la dimensión general, resaltan como procesos críticos de determinación, que limitan la producción y el acceso de frutas y verduras, el uso y tenencia inequitativa de la tierra y la explotación de las fuentes hídricas, y unas políticas que desde la lógica de libre mercado reducen cada vez más las estrategias locales de autosostenimiento y autoconsumo. En la dimensión particular, el conflicto armado (como proceso crítico adverso) y los ejercicios de soberanía alimentaria (como proceso crítico favorable al consumo de frutas y verduras). Conclusiones: la política alimentaria nacional y local reconoce, de manera discursiva, las determinaciones sociales de la seguridad alimentaria, pero en la práctica privilegia estrategias focalizadas y contingentes que no apuntan a la solución de condiciones estructurales que limitan la producción, disponibilidad, acceso y, por ende, el consumo de frutas y verduras
Introduction: Fruit and vegetable consumption as a preventive health measure depends mainly on the perspective of individual lifestyle. The structural processes such as food production models and food policies determine their production, availability, and access. This study aimed to analyze the social determinants of fruit and vegetable consumption in the municipality of Florida, Valle del Cauca, Colombia. Materials and Methods: This is a qualitative case study using a social determination approach. This study includes a documentary review of food policies and discussion groups among key stakeholders. A content analysis was conducted to allow an explicit analysis of the messages and speeches. Results: In the general dimension, deemed as critical processes of determination, the unequal use and possession of land and the exploitation of water sources and policies, from the logic of the free market, increasingly reduce the local strategies for self-support and self-consumption and limit the production and access of fruits and vegetables. In the particular dimension, a critical adverse process includes the armed conflict. However, the exercise of food sovereignty favors the consumption of fruits and vegetables. Conclusion: Food policy at the national and local level discursively recognizes the social determinants of food security; however, in practice, contingent strategies that do not aim at addressing the structural conditions that limit produc- tion, availability, access and, therefore, the consumption of fruits and vegetables, should be evaluated.

Materiais e métodos: estudo qualitativo, do tipo estudo de caso, com enfoque na determinação social; incluiu uma revisão documental de políticas alimentares e grupos de discussão com atores-chave; a análise de conteúdo permitiu explicitar mensagens e discursos. Resultados: na dimensão geral, destacam-se o uso e posse desigual da terra e a exploração dos recursos hídricos como processos determinantes críticos que limitam a produção e o acesso a frutas e verduras; e políticas que, baseadas na lógica do livre mercado, reduzem cada vez mais as estratégias locais de autossustentabilidade e autoconsumo. Na dimensão particular, destaca-se o conflito armado como processo crítico adverso, e o exercício da soberania alimentar, como processo crítico favorável ao consumo de frutas e verduras. Conclusões: a política alimentar a nível nacional e local reconhece, de forma discursiva, as determinações sociais da segurança alimentar, mas na prática privilegia estratégias focalizadas e contingentes que não visam resolver condições estruturais que limitam a produção, a disponibilidade, o acesso e, portanto, o consumo de frutas e verduras.

Consumption of fruits and vegetables which are known to be highly nutritious has been linked to foodborne disease outbreaks which constitute food safety and public concern. This study aimed to assess the safety of selected fruits and vegetables from fruit markets and home gardens, within the South-West region of Nigeria. A total of fifty-three (53) samples of watermelon, cucumber, tomatoes and garden eggs were collected and subjected to microbiological analysis. Isolated bacteria were screened for their pathogenicity and spoilage potential using haemolysis and amylase production tests respectively. A total of 146 bacteria were isolated, 75 (45.7%) were from retail samples and 71 (43.3%) from the home garden. The genera: Bacillus (15.9%), Corynebacterium (11.0%), Lactobacillus (1.2%), Listeria (1.8%), Staphylococcus (12.8%), Enterococcus (1.2%), Micrococcus (1.2%), Acinetobacter (3.7%), Aeromonas (2.4%), Alcaligenes (0.6%), Brucella (0.6%), Vibrio (0.6%), and the family Enterobacteriaceae (36.0%) were identified. Isolates with haemolytic potentials were 51 (31%) while 49 (30%) could cause spoilage. The overall microbiological quality and safety of fruit and vegetable samples analysed in this study is low, as they were contaminated by diverse pathogenic, and spoilage microorganisms. The presence of these pathogens in retailed and home garden fruits and vegetables is a pointer to public health risks and food safety threats. Hence, the need for improved hygienic practice through training handlers along the supply chain.
ABSTRACT
Background: Despite control measures to curtailed salmonella fruit contamination over the years, pathogenic disease outbreaks caused by the ingestion of Salmonella contaminated fresh-cut-fruits pose a significant problem to human health by the consumption of fresh and minimally processed fruits. This study aimed to enumerate and determine the prevalence of Salmonella species isolated in ready-to-eat fruits vended in Bukuru Market Jos South, Plateau state. Methodology: A total of seventy-eight ready-to-eat vended fruit samples were purchased and cultured for the enumeration of bacterial isolates according to National Food Safety Standard for Microbiological Examination. Pulp pH value of each fruit was obtained by immersing litmus paper into the pulp and results recorded. Results: Of the 78 fruits specimen, 22 (28.2%) were Salmonella positive. The prevalence rates of salmonella isolated were found to be higher (22.7%) in both coconut and avocado followed by watermelon (18.2%) and sweetmelon (13.6%) as compared with other fruits in the study area. Lower rates of 4.5% were found in banana, pawpaw, and dates with a rise in apple with 9.1% respectively. Conclusion: The study showed a high p<0.05 (7.811) prevalence of pathogenic Salmonella species isolated in ready-to-eat fruits in the study area revealing that the spread of salmonella is not independent of fruits thereby suggestive of contamination made available by fruit vendors in this part of the world. Thus, epidemiological traceability and significant measures must be taken to check the safety of these vended products before consumption.
ABSTRACT
Trinta a 60% das alergias alimentares em adolescentes e adultos são associadas à alergia ao pólen e estão incluídas na síndrome pólen-frutas (SPF). Esta síndrome é caracterizada por sintomas alérgicos provocados pela ingestão de frutas ou vegetais frescos em pacientes com rinite/rinoconjuntivite alérgica sazonal. Os autores apresentam o caso clínico de um adolescente que após sensibilização primária através de pólens de gramíneas e oliveira manifestou posteriormente, por reatividade cruzada, sintomas de alergia oral com a ingestão de frutas frescas. Após recurso ao método de diagnóstico Immuno-Solid-Phase Allergen Chip (ISAC) verificou-se que as profilinas foram as proteínas responsáveis pela reatividade cruzada.
In adolescents and adults, 30% to 60% of food allergies are associated with pollen allergy and are included in the pollen-food syndrome (PFS). This syndrome is characterized by allergic symptoms elicited by the ingestion of fresh fruits or vegetables in patients with seasonal allergic rhinitis/rhinoconjunctivitis. The authors present the clinical case of an adolescent who, after primary sensitization to grass and olive tree pollens, subsequently manifested by cross-reactivity symptoms of oral allergy with the ingestion of fresh fruit. After diagnostic workup with the Immuno- Solid-phase Allergen Chip (ISAC) assay, profilins were identified as the proteins responsible for the cross-reactivity.

Abstract This study aimed at assessing the association between psychosocial aspects and fruit and vegetable consumption in adolescents. Cross-sectional study developed with 327 adolescents from a public school in Brazil. A questionnaire developed for adolescents was applied to assess the influence of self-efficacy, family, peers, and body image on the consumption of fruits and vegetables. Specific questions assessed the intake frequency of fruits and vegetables, and the mean consumption was estimated using two 24-hour recalls. Scores related to psychosocial aspects were described as mean and median and the weight status was classified based on the body mass index. The average daily consumption of fruits and vegetables was 36.2 g and 45.4 g, respectively. Self-efficacy and the influence of peers were associated with an increase in the amount and frequency of fruits and vegetables consumption. Adolescents with higher scores of self-efficacy had greater average consumption of fruits and vegetables when compared to those with lower scores. The same was observed for the influence of peers. Self-efficacy and the influence of peers were the factors that most influenced the consumption of fruits and vegetables in adolescents.
Resumo O objetivo do estudo foi avaliar a associação entre aspectos psicossociais e o consumo de frutas e hortaliças em adolescentes. Estudo transversal desenvolvido com 327 adolescentes de uma escola pública do Brasil. Um questionário desenvolvido para adolescentes foi aplicado para avaliar a influência da autoeficácia, família, pares e imagem corporal sobre o consumo de frutas e hortaliças. Questões específicas avaliaram a frequência de ingestão de frutas e hortaliças e o consumo foi estimado por meio de dois recordatórios de 24 horas. Os escores relacionados aos aspectos psicossociais foram descritos por média e mediana e a condição de peso foi classificada com base no índice de massa corporal. O consumo diário médio de frutas e hortaliças foi de 36,2 g e 45,4 g, respectivamente. A autoeficácia e a influência dos pares associaram-se ao aumento da quantidade e da frequência de consumo de frutas e hortaliças. Os adolescentes com maiores valores no escore para autoeficácia apresentaram maior média de consumo de frutas e hortaliças quando comparados àqueles com menores escores. O mesmo foi observado para a influência dos pares. A autoeficácia e a influência dos pares foram os fatores que mais influenciaram o consumo de frutas e hortaliças em adolescentes.
ABSTRACT
Aims: This study aimed to assess the in vitro antibacterial effects of extracts from four wild food fruits: Balanites aegyptiaca, Saba senegalensis, Ziziphus mauritiana, and Raphia sudanica. Place and Duration of Study: The samples of plant material were collected at Banamba and Sikasso, Mali between January and May 2018. The bacterial strains were collected at Research Centre for Biological Food and Nutritional Sciences (CRSBAN), University Professor Joseph Ki-Zerbo; Ouagadougou, Burkina Faso. The experimental parts were also carried out at CRSBAN from October 2019 to January 2020. Methodology: The fruit extracts were screened for antibacterial activity against Escherichia coli, Salmonella typhi, S. aureus, B. cereus, and L. monocytogenes strains. The diameters of the inhibition zones (ID), the minimum inhibitory concentrations (MIC) as well as the minimum bactericidal concentrations (MBC) were evaluated using agar diffusion method. Results: The findings revealed that these parameters have varied as a function of fruit species and/or their zones of provenances. All fruit extracts showed significant growth reducing effect against all the tested bacteria. The extracts from R. sudanica have exhibited the strongest growth-inhibiting activity specifically against E. coli (ID = 15.33±0.58 mm) and Salmonella typhi (ID = 18.00±1.00 mm) with lower MIC (from 2.08±1.44 to 5.83±1.44 mg/mL). Moreover, the MBC/MIC ratios revealed that the extracts from the studied fruits possess mainly bacteriostatic effects towards the tested strains. Conclusion: These findings support local therapeutics properties attributed to these fruits. They also demonstrate that, in addition to their nutritional values, these edible fruits could be used for developing antibiotics to treat infectious diseases and food poisoning.
ABSTRACT
Kelussia odoratissima fruits are utilized in Persian traditional medicine as a painkiller and to prevent inflammation-based disorders. Considering the higher content of essential oil in the fruits, the oil's anti-inflammatory and analgesic activities were investigated via the paw edema triggered in mice and the writhing test and hot plate technique, respectively. It was observed that the 100, and 200 mg/Kg doses of the oil revealed an analgesic impact (p<0.001) considering the increment in the reaction time needed for the hot plate approach. Furthermore, 100 and 200 mg/Kg doses of the oil caused a reduction in the frequency of writhes in the mice (p<0.01 and p<0.001, respectively). Using all examined doses of theoil (25, 50, and 100 mg/Kg) caused inflammatory reduction (p<0.001). The findings indicated that the oil possess significant activities against acute inflammation. It had both peripheral and central pain-killing impacts. The main components 3-n-butylphthalide (28.3%) and germacrene D (17.3%) can be considered as the responsible compounds to manage the inflammation and pain.

The chemical constituents from the fruits of Morinda citrifolia were systematically explored by chromatographic fractionation methods including silica gel, octadecylsilyl(ODS) gel, Sephadex LH-20 gel, and preparative high performance liquid chromatography(pre-HPLC). The chemical structures of all isolated compounds were identified on the basis of their physicochemical properties, spectroscopic analyses, as well as the comparisons of their physicochemical and spectroscopic data with the reported data in literature. As a result, 22 isolated compounds from the 90% ethanol extract of the fruits of M. citrifolia were identified, which were moricitritone(1), 2'-deoxythymidine(2), cyclo-(L-Pro-L-Tyr)(3), methyl-5-hydroxy-2-pyridinecarboxylate(4), methyl pyroglutamate(5), bisbenzopyran(6), epipinoresinol(7), 3, 3'-bisdemethyl pinoresinol(8), 3, 3'-bisdemethyltanegool(9), trimesic acid(10), crypticin B(11), kojic acid(12), vanillic acid(13), protocatechoic acid(14), 5-hydroxymethyl furfural(15), blumenol A(16), 1-O-(9Z, 12Z-octadecadienoyl) glycerol(17), mucic acid dimethylester(18), methyl 2-O-β-D-glucopyranosylbenzoate(19), 2-phenylethyl-O-β-D-glucoside(20), scopoletin(21), and quercetin(22). Among them, compound 1 was a new pyrone derivative, compounds 2, 4-7, 10-12, and 17 were isolated from the plants belonging to Morinda genus for the first time, and compound 18 was obtained from M. citrifolia for the first time. Moreover, on the basis of testing the activities of all isolated compounds on inhibiting the proliferation of synovial fibroblasts in vitro by MTS assay, the anti-rheumatoid arthritis activities of all isolated compounds were initially evaluated. The results showed that compounds 1-6, 9, 19, and 20 exhibited remarkable anti-rheumatoid arthritis activities, which displayed the inhibitory effects on the proliferation of MH7A synovial fibroblast cells with the IC_(50) values in the range of(3.69±0.08) to(168.96±0.98) μmol·L~(-1).

ABSTRACT
Abstract The present study was aimed at conducting phytochemical analysis and evaluating the in vitro antifungal and antioxidant activities of the essential oil obtained from the fruits of J. oxycedrus L. Hydro-distillation was used to extract the essential oil from the fruits of Juniper oxycedrus. The essential oil was analyzed using gas chromatography with a flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). The antioxidant activity of the essential oil against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals was determined in vitro using varying concentrations of the essential oil and vitamin C as a standard antioxidant compound. A disc diffusion test was employed to evaluate the antifungal activity of the essential oil against two test fungal strains, Penicillium citrinum, and Aspergillus niger. The results revealed that 49 constituents were identified in fruit oil, representing 91.56% of the total oil and the yield was 1.58%. Juniper fruit oil was characterized by having high contents of ß-pinene (42.04%), followed by limonene (15.45%), sabinene (9.52%), α-pinene (5.21%), (E)-caryophyllene (3.77%), ρ-cymene (1.56%), caryophyllene oxide (2.02%), and myrcene (1.02%). The radical scavenging activity (% inhibition) of the essential oil was highest (81.87± 2.83%) at a concentration of 200 µg/mL. The essential oil of J. oxycedrus exhibited antifungal activity against A. niger and P. citrinum with minimum inhibitory concentration values (MIC) ranging from 2.89 to 85.01 µl/mL. The findings of the study reveal that the antioxidant and antifungal properties of J. oxycedrus essential oil and their chemical composition are significantly correlated
