Effect of packaging materials and storage environment on fennel seedling growth / Efeito da embalagem e do ambiente de armazenamento no crescimento de plântulas de erva doce

The objective of the present study was to assess the influence of the packaging material (cotton cloth bag, multifolium paper and glass container) and storage environment (laboratory and cold chamber conditions) on fennel seedling growth. Seeds were placed in different packaging materials and exposed to the two environments for twelve months. Assessments were made before storage and at every two months and the following were determined: total emergence, emergence speed index, seedling fresh and dry matter. A completely randomized experimental design was used, with four replications in a 2 x 3 x 6+1 factorial design in split split plots, where the plot was the storage environment (laboratory and cold chamber conditions); the split plot was the storage (cotton cloth bag, multifolium paper and glass container) and the split plot was the storage periods (2, 4, 6, 8, 10 and 12 months) and plus an additional treatment (before storage). The results showed that the fennel seedlings had superior growth when their seeds were placed in the glass packaging material, regardless of the storage environment.

O objetivo deste trabalho foi avaliar a influência da embalagem (saco de algodão, papel multifoliado e vidro) e do ambiente de armazenamento (condições de laboratório e câmara fria) no crescimento de plântulas de erva doce.

Foeniculum vulgare as Valuable Plant in Management of Women's Health

This review paper evaluates use of Foeniculum vulgare extracts as a popular female plant in management of different ailments of women. Information in this paper was gathered from accessible sources (PubMed, Science Direct, Springer, Wiley, and Google), and traditional books (Persian or English modern traditional books), unpublished data (R&D reports, thesis and dissertation) by keywords based on the words F. vulgare or fennel and women. Efficacy of oral fennel oil in management of dysmenorrhea, premenstrual syndrome, amenorrhea, menopause, lactation, and polycystic ovary syndrome were confirmed according to results of clinical studies. Results of clinical efficacy of fennel oil on menstrual bleeding is complicated, but results of one meta-analysis study revealed that fennel oil significantly increased means of bleeding in the first menstrual periodic cycle (P = 0.001), while fennel oil had no significant effect on bleeding in the second menstrual cycle (P = 0.67). Topical and vaginal fennel extract (5%) exhibited good efficacy in treatment of sexual function, vaginal atrophy, and hirsutism. Fennel had no effect on bone density, or body mass index of menopause women. Results of clinical studies introduce fennel as a valuable medicinal plant in management of women's ailments, but understanding the mechanism of action could be the subject of future studies.

Management of acute cough by Zataria multiflora Boiss as an alternative treatment / 中西医结合学报

Cough, as a defensive reflux mechanism, removes foreign objects and secretions from bronchi and bronchioles of airways. Zataria multiflora is a popular plant for treatment of cough in Iranian traditional medicine. The aim of this review was to evaluate the potency of Z. multiflora as an alternative treatment in management of acute cough and its possible mechanisms of action. Here the authors compiled information about Z. multiflora in the treatment of cough from all accessible resources and books. The results of this investigation showed that there were five clinical studies that evaluated the efficacy of Z. multiflora essential oil or extract alone (n = 1), in combination with Althaea officinalis (n = 2) or Foeniculum vulgare essential oil (n = 1), in the form of syrup (n = 3), oral drop (n = 1) and soft capsule (n = 1), for the treatment of acute cough in comparison with placebo or synthetic drugs (bromhexine, dextromethorphan and clobutinol). All clinical studies confirmed the efficacy of Z. multiflora in the amelioration of acute cough in pediatric (n = 1) and adult patients (n = 4) without any adverse effects. Different mechanisms, such as anti-inflammatory, analgesic, antimicrobial, relaxant and immune-enhancement, may be responsible for the efficacy of Z. multiflora in cough relief. Other clinical trials can be performed with Z. multiflora in combination with ivy leaf extract or primrose root extract on patients with cough.

Extraction kinetics of volatile components from Foeniculum vulgare by steam distillation / 中草药

Objective To reveal the dissolution rule of volatile oil in the extraction processfrom Foeniculum vulgare by GC-MS analysis. Methods The volatile oil of F. vulgare was extracted by steam distillation; The volatile oil/perfume system was collected at fixed time interval (30 min); The volatile oil part and perfume part were separated. Using N-docosane and methyl myrisate as double internal standard, GC-MS was selected for analysis and quantification. The main components were extracted by thermography, and the distribution regularity of components was definited. The principal components with the impact on the composition distribution were investigated according to the physical and chemical properties of the molecular weight, melting point, boiling point, and density of the compounds. Results The GC-MS analysis results concluded 123 volatile components. The main components were estragole, anethole, and (R)-(+)-limonene. There were 60 and 27 endemic components in aromatic aqueous solution and volatile oil, respectively, in which 27were common composition. The content of anethole in water was positively related to the endemic components in aromatic water, and even had a positive correlation with anethole artemisia content and (R)-(+)-limonene content. The specific components in the oil were positively related to the content of the main components (R)-(+)-limonene in the volatile oil. The principal component analysis showed that the physical and chemical properties of the compounds were important factors affecting the distribution of components; PC1 (molecular weight and positive correlation of melting point), PC2 (refractive index positive correlation), and PC3 (water-soluble negative correlation) were the principal components that lead to differences in component distribution. Conclusion In the process of extracting volatile oil from F. vulgare, steam distillation is affected by the physical and chemical properties of volatile components. Some components are specifically distributed in aromatic perfume and volatile oil system. The endemic components of aromatic water increase the content of the main components in the water system, which may lead to theproduction of "emulsification" during the extraction process of volatile oil and reduce the yield and quality of volatile oil.

Antifungal potential of the Seed and Leaf Foeniculum vulgare Mill essential Oil in liquid and vapor phase against phytopathogenic fungi.

Analysis of essential oils obtained from the seeds (SEO) and leaves (LEO) of Foeniculum vulgare Mill cultivated in southeast of Morocco revealed that trans-anethole was the major constituent (54.67% of seed oil and 50.60% in leaf oil), followed by estragol (35.33% of seed oil and 30.15% in leaf oil). Other components present in leaf oil included fenchone, linalool and α-pinene, while seed oil contained fenchone, limonene and γ-terpinen. Besides, minor constituents like camphene, camphor, myrcene, pahllandrene, fenchyl acetate and β-bisabolene were obtained from seeds and leaves. The essential oils of the seeds and leaves of Foeniculum vulgare were assayed for their antifungal activity by poison food (PF) technique and the volatile activity assay (VA) against five agricultural pathogenic fungi. The results indicated that the essential oil of Foeniculum vulgare inhibited the mycelial growth of all fungal strains tested. VA assay of essential oil was consistently found to be more effective than PF technique. The mycelium growth was completely inhibited by LEO on Alternaria sp., Fusarium oxysporum f. sp. albedinis and Aspergillus brasiliensis at 0.25 μl mL-1 air. Rhizopus stoloniferawas the most sensitive with a minimal inhibitory concentration (MIC) = 0.25 μl mL-1 air.

Foeniculum vulgare Mill. Protects against Lipopolysaccharide-induced Acute Lung Injury in Mice through ERK-dependent NF-kB Activation

Foeniculum vulgare Mill. (fennel) is used to flavor food, in cosmetics, as an antioxidant, and to treat microbial, diabetic and common inflammation. No study to date, however, has assessed the anti-inflammatory effects of fennel in experimental models of inflammation. The aims of this study were to investigate the anti-inflammatory effects of fennel in model of lipopolysaccharide (LPS)-induced acute lung injury. Mice were randomly assigned to seven groups (n=7~10). In five groups, the mice were intraperitoneally injected with 1% Tween 80-saline (vehicle), fennel (125, 250, 500micro l/kg), or dexamethasone (1 mg/kg), followed 1 h later by intratracheal instillation of LPS (1.5 mg/kg). In two groups, the mice were intraperitoneally injected with vehicle or fennel (250microl/kg), followed 1 h later by intratracheal instillation of sterile saline. Mice were sacrificed 4 h later, and bronchoalveolar lavage fluid (BALF) and lung tissues were obtained. Fennel significantly and dose-dependently reduced LDH activity and immune cell numbers in LPS treated mice. In addition fennel effectively suppressed the LPS-induced increases in the production of the inflammatory cytokines interleukin-6 and tumor necrosis factor-alpha, with 500microl/kg fennel showing maximal reduction. Fennel also significantly and dose-dependently reduced the activity of the proinflammatory mediator matrix metalloproteinase 9 and the immune modulator nitric oxide (NO). Assessments of the involvement of the MAPK signaling pathway showed that fennel significantly decreased the LPS-induced phosphorylation of ERK. Fennel effectively blocked the inflammatory processes induced by LPS, by regulating pro-inflammatory cytokine production, transcription factors, and NO.

Fennel (Foeniculum vulgare) and Fenugreek (Trigonella foenum-graecum) Tea Drinking Suppresses Subjective Short-term Appetite in Overweight Women

Appetite controlling has been an main strategy for regulating food intake and energy balance in obesity treatment. The aim of this study was to examine the effects of drinking tea of the medicinal herbs, fennel and fenugreek, on the subjective appetite in overweight Korean women. The study was conducted using a placebo-controlled, single-blinded, randomized, and 3-way crossover design. Nine healthy women were given fennel tea (FT), fenugreek tea (FGT), or placebo tea (PT). After drinking a given tea, a lunch buffet was provided and then food consumption of subjects was analyzed. Subjective appetite, hunger, fullness, desire to eat, and prospective food consumption were measured at seven independent time point using a visual analog scale (VAS). Mean age of 9 subjects were 49.7 +/- 4.5 years and their mean body mass index were 24.6 +/- 0.6 kg/m2. There was no significant difference in food consumption in the lunch buffet after drinking each tea; however, with respect to the subjective appetite scale, FGT decreased hunger, led to less prospective food consumption, and increased feelings of fullness compared with the PT (p < 0.05). Similarly, the consumption of FT resulted in decreased hunger, less prospective food consumption, and increased feelings of fullness compared with the PT (p < 0.05). The area under the curve of VAS graph indicated that FGT resulted in a higher feeling of fullness than the PT (p < 0.05). In conclusion, drinking the FT and FGT were significantly effective aid to suppress subjective appetite among overweight women in South Korea.

Antidepressant Activity of Methanolic Extract of Foeniculum Vulgare (Fennel) Fruits in Experimental Animal Models.

The present study was undertaken to investigate the effects of methanolic extract of Foeniculum vulgare fruits (family: umbelifereae), popularly known as fennel, on depression using force swim test in rats, potentiation of norepinephrine toxicity in mice and haloperidol induce catalepsy in mice. The extract of F.vulgare (250 and 500 mg/kg) was administered orally to rats used in FST and 500mg/kg was administered in HIC and same dose administered in NE toxicity in mice. The dose of 250mg/kg and 500mg/kg of extract significantly (p<0.001) reduced the immobility times in rats but dose of 500 mg/kg showed more potent effect than imipramine (30mg/kg). So this dose was used in HIC and NE toxicity in mice. But in NE toxicity model it was observed that MEFV is not good adrenergic component. A significant (P<0.001) reduction in the duration of catalepsy was observed in the MEFV treated group and Fluoxetine group as compared to the haloperidol treated group. In HIC, mice were sacrificed on the seventh day and TBARS, glutathione, nitrite activities were estimated. Monoamine oxidase inhibiting effect and anti-oxidant effect of Foeniculum vulgare may be contributing favorably to the antidepressant-like activity. Thus, it is concluded that Foeniculum vulgare extract may possess an antidepressant-like effect.

Avaliação biológica de Foeniculum vulgare (Mill. ) (Umbelliferae/Apiaceae) / Biological evaluation of Foeniculum vulgare (Mill. ) (Umbelliferae/Apiaceae)

Foeniculum vulgare Mill. é espécie herbácea da família Umbelliferae, nativa da região do Mediterrâneo e da Ásia Menor, amplamente distribuída em todo o território brasileiro. É conhecida popularmente como funcho ou erva-doce e usada na medicina como analgésico, digestivo, carminativo, diurético, expectorante, lactígeno, anti-inflamatório, e antiespasmódico. O extrato bruto etanólico para a verificação das atividades biológicas foi preparado a partir de sementes compradas no comércio. Para a realização do perfil fitoquímico foi utilizada a cromatografia em camada delgada analítica; a atividade antimicrobiana foi determinada pelo teste de difusão em disco de papel e da concentração inibitória mínima (CIM); a atividade antinociceptiva foi realizada pelo método de contorções abdominais em cobaias. Os micro-organismos testados foram isolados clínicos multirresistentes obtidos do Setor de Bacteriologia do Hospital das Clínicas de Pernambuco. O estudo fitoquímico identificou a maioria dos compostos secundários presentes na fração metanólica das sementes, sendo eles: triterpenos, glicosídeos de flavanóides, terpenos menores (monoterpenóides, sesquiterpenóide e diterpenóides), e açúcares redutores. Os resultados obtidos mostraram que o extrato etanólico apresentou maior atividade frente à Micrococcus spp. (CIM=250µg/mL). Os resultados da avaliação da atividade antinociceptiva demonstraram que apenas a dosagem de 298 mg/Kg quando comparado com o padrão indometacina conseguiu uma redução significativa no número de contorções abdominais dos animais. Estudos posteriores deverão ser realizados para a identificação e isolamento de alguns compostos secundários, bem como a realização de outros protocolos de analgesia.

Foeniculum vulgare Mill. (Umbelliferae) is a herbaceous plant of the family Umbelliferae, native to the Mediterranean and Asia Minor region and widely distributed all over the Brazilian territory. It is commonly known as fennel or "erva-doce" and has been used in medicine as analgesic, digestive, carminative, diuretic, expectorant, lactigenous, anti-inflammatory, and antispasmodic agent. Crude ethanolic extract for the verification of biological activities was prepared from seeds bought in the market. For the phytochemical profile, analytical thin-layer chromatography was used; the antimicrobial activity was determined by the paper disc diffusion test and minimum inhibitory concentration (MIC); the antinociceptive activity was verified by the method of abdominal writhings in the animals. The tested microorganisms were multiresistant clinical isolates obtained from the Bacteriology Sector of the Clinical Hospital of Pernambuco. The phytochemical study identified the majority of secondary compounds present in the methanolic fraction of seeds, as follows: triterpenes, flavanoid glycosides, smaller terpenes (monoterpenoids, sesquiterpenoids and diterpenoids) and reducing sugars. The obtained results showed that the ethanolic extract had greater activity against Micrococcus spp. (MIC=250µg/mL). Results of the evaluation of the antinociceptive activity demonstrated that only the dosage of 298 mg/Kg, compared to the indomethacin pattern, led to a significant reduction in the number of abdominal writhings in the animals. Further studies will be carried out for the identification and isolation of some secondary compounds, as well as other analgesic protocols.

Evaluation of antifungal activity of essential oils against potentially mycotoxigenic Aspergillus flavus and Aspergillus parasiticus

The antifungal activity of essential oils of fennel (Foeniculum vulgare Mill., Apiaceae), ginger (Zingiber officinale Roscoe, Zingiberaceae), mint (Mentha piperita L., Lamiaceae) and thyme (Thymus vulgaris L., Lamiaceae) was evaluated against mycotoxin producers Aspergillus flavus and A. parasiticus. High Resolution Gas Chromatography was applied to analyze chemical constituents of essential oils. The effect of different concentrations of essential oils was determined by solid medium diffusion assay. Mycelial growth and sporulation were determined for each essential oil at the concentrations established by solid medium diffusion assay. At the fifth, seventh and ninth days the mycelial diameter (Ø mm) and spore production were also determined. FUN-1 staining was performed to assess cell viability after broth macrodilution assay. Trans-anethole, zingiberene, menthol and thymol are the major component of essential oils of fennel, ginger, mint and thyme, respectively. The effective concentrations for fennel, ginger, mint and thyme were 50, 80, 50 and 50% (oil/DMSO; v/v), respectively. The four essential oils analysed in this study showed antifungal effect. Additionally, FUN-1 staining showed to be a suitable method to evaluate cell viability of potential mycotoxigenic fungi A. flavus and A. parasiticus after treatment with essential oils.

Fennel and basil have been used for a long time in popular medicine as antispasmodic to alleviate gastrointestinal colics and complaints. The effect of 10% of dry leaves of basilinfusion (Ocimum basilicum) as well as fennel infusion (Foeniculum vulgare) was evaluated. The mixture of both infusions 1:1 in the tone of a rat contracted ileum were also evaluated in vitro. A decrease in the tone compared with the distilled water in equal quantities was seen. This one was a dependent dose with a statistical meaningful difference for each oneof the plants and the mixture. We did not find out an additive effect with the two plants mixture. The study showed the relaxing effect of the fennel and basil 10% infusion, in the tone of the pre-contracted rat’s ileum.

Sazonalidade dos ductos secretores e óleo essencial de Foeniculum vulgare var. vulgare Mill. (Apiaceae) / Seasonality of the secretory ducts and essential oil of Foeniculum vulgare var. vulgare Mill. (Apiaceae)

Este trabalho teve como objetivo analisar os ductos secretores e o óleo essencial das folhas de Foeniculum vulgare em diferentes épocas do ano. Para esta finalidade, foram realizados estudos de caracterização anatômica, bem como anatomia comparada dos ductos secretores e testes histoquímicos das folhas. O óleo essencial foi obtido de folhas e frutos, por hidrodestilação em aparelho de Clevenger e analisados quantitativamente e qualitativamente por cromatografia em fase gasosa acoplada ao espectrômetro de massa, realizando-se análises seguidas de três réplicas para folhas coletadas durante o inverno e primavera, e frutos no verão. Os resultados encontrados para os ductos secretores de óleo corresponderam à redução do teor de óleo essencial nas folhas coletadas no final da primavera. O componente majoritário do óleo essencial de folhas e frutos foi o trans-anetol, durante todas as estações do ano. Portanto, evidenciou-se que os ductos secretores e teor de óleo essencial estão relacionados, bem como os constituintes químicos também estão sujeitos a sazonalidade, conforme o estágio fenológico da planta.

This work aimed to analyze the secretory ducts and the essential oil of the leaves of Foeniculum vulgare in different periods of the year. For this purpose, the anatomic characterization, and histochemical tests of the leaves were performed as well as the comparative anatomy of the secretory ducts. The essential oil was obtained from the leaves and fruits by hidrodistillation in a Clevenger-type apparatus and analyzed by gas chromatography coupled to a mass spectrometer, each analysis was repeated three times for leaves collected during the winter and spring, and for fruits collected in the Summer. The results obtained for the secretory ducts, corresponded to the yield reduction of essential oil in the leaves collected in the end of the spring. The major substance of the essential oil of the leaves and fruits, in all seasons of the year was trans-anetol. Therefore, it was evidenced that the secretory ducts and yield of essential oils are related, and also that the substances are subject to the seasonality, according to the phenologic stage of the plant.

Polyploidy of Foeniculum vulgare induced by colchicine / 中草药

Objective To explore the induced effects of colchicine in different concentration and times on Foeniculum vulgare polyploidy.Methods Seed germination rate and mutation rate,morphology of radicle induced mutants,chromosome number,tissue structure,and content and component of essential oil,which induced by colchicine in different concentiation and times were investigaled using the method of soaking seeds.Results The results showed that 0.13% of colchicine concentration and 24 h inducing time had the best induction on F.vulgare polyploidy.Compared to the control,the radicle of mutant was thicker,the chromosome number increased clearly,and the cell number in radicle manifolded distinctly.Among the four main components of essential oil,the contents of Dill apiol in anamorphosis radicle was a little lower than that of the control,but the contents of limonene,(E)-anethole,and camphene in anamorphosis radicle were all remarkably higher than that of the control after induced by colchicine.ConclusionThe content of main essential oil components in fennel mutant induced by colchicine is remarkably enhanced.The study provides the theoretical basis for the breeding of F.vulgare new varieties of high oil content.
