    Ever since the discovery of X-ray and radioactivity at the end of the 19th century, cellular and molecular responses to ionizing radiation exposures have been the central research endeavors in radiation biology. The most striking aspect of the action of the ionizing radiation on biological material of all kinds is the grave damage produced by relatively trivial amounts of absorbed energy. Radiation damage occurs through the formation of free radical and reactive oxygen species in living organisms and these radicals are highly reactive and cause alterations in DNA, membrane and proteins by reacting with nucleotides, lipids and amino acids which is eventually reflected in cellular dysfunctions. The study of plants as modifiers of radiation effects is a relatively new area of research. There are various adaptive changes which a cell invokes to protect itself from radiation induced unhealthy biochemical changes and this can be supported by food supplements such phytochemical rich diets. Herbal medicines i.e. plant products have been considered as an alternative to synthetic compounds due to their better cultural acceptability, better efficacy, less toxicity and better compatibility with human body. Research has proved that the Trigonella foenum-graecum can inhibit the cancer of liver, lower blood cholesterol levels and also have an anti-diabetic effect. The whole extract of Trigonella foenum-graecum has been reported to contain several bioactive components such as glucoside, alkaloids, bitter principle crystalline compounds which elicit protection against several stress and pathological conditions by acting through different mechanisms such as antioxidant, stimulation of cell proliferation immunomodulational and anti-inflammatory activity. Therefore, the present study has been undertaken to screen possible radioprotective potential of Trigonella foenum-graecum extract (TFE) against irradiation.

    Orobanche crenata is a major threat to grain legume production. Fenugreek (Trigonella foenum-graecum) is an annual legume that has been shown to effectively reduce O. crenata infection when intercropped with grain legumes. In this paper, we point that this can be attributed to allelopathy, through inhibition of the germination of O. crenata by fenugreek root exudates. The main inhibitory metabolite was isolated and characterized. Allelopathy was demonstrated in different bioassays, by inhibition of O. crenata seeds germination both by growing fenugreek and pea plants together (intercropped), and by application of fenugreek root exudates. Fenugreek root exudates were extracted with organic solvent and fractionated giving several fractions, two of which showed moderate (27%) and strong (54%) inhibition of O. crenata seed germination, respectively. The most active metabolite is a new monosubstituted trioxazonane, characterized by spectroscopic methods as the 2-butyl-[1,4,7,2]trioxazonane and named trigoxazonane.

    Spices and herbs possess antioxidant activity and can be applied for preservation of lipid peroxidation in biological systems. Fenugreek (Trigonella foenum-graecum) is an important spice; its dried seeds have wide application in food and beverages as a flavoring additive as well as in medicines. Crude extracts of fenugreek were prepared by soxhelt extraction method with different solvents such as methanol, ethanol, dichloromethane, acetone, hexane and ethyl acetate. Extracts were subjected for the measurement of total phenolic content (TPC) by Folin-Ciocalteu method as well as flavonoid content, chelating activity, reducing power and antioxidant/radical scavenging activity (1,1-diphenyl-2-picryl-hydrazyl (DPPH degree) free radical scavenging activity). Results from different parameters were in agreement with each other. The results reveal that all extracts of the fenugreek exhibit antioxidant activity. These findings suggest that the fenugreek extracts could act as potent source of antioxidants. (author)

    Full Text Available Trigonella foenum-graecum seed powder (TSP has been reported to have hypoglycemic and hyperinsulinemic action. The objective of the study was to examine the antidiabetic and neuroprotective role of TSP in hyperglycemiainduced alterations in blood glucose, insulin levels and activities of membrane linked enzymes (Na+K+ATPase, Ca2+ATPase, antioxidant enzymes (superoxide dismutase, glutathione S-transferase, calcium (Ca2+ levels, lipid peroxidation, membrane fluidity and neurolipofuscin accumulation in the diabetic rat brain. Female Wistar rats weighing between 180 and 220 g were made diabetic by a single injection of alloxan monohydrate (15 mg/100 g body weight, diabetic rats were given 2 IU insulin, per day with 5% TSP in the diet for three weeks. A significant increase in lipid peroxidation was observed in diabetic brain. The increased lipid peroxidation following chronic hyperglycemia was accompanied with a significant increase in the neurolipofuscin deposition and Ca2+ levels with decreased activities of membrane linked ATPases and antioxidant enzymes in diabetic brain. A decrease in synaptosomal membrane fluidity may influence the activity of membrane linked enzymes in diabetes. The present study showed that TSP treatment can reverse the hyperglycemia induced changes to normal levels in diabetic rat brain. TSP administration amended effect of hyperglycemia on alterations in lipid peroxidation, restoring membrane fluidity, activities of membrane bound and antioxidant enzymes, thereby ameliorating the diabetic complications.

    Full Text Available Background: Macrophages are key cellular mediators in diabetes-related inflammation. Molecular cues such as cytokines found in the tissue microenvironment regulates the polarization of macrophages into an M1 (pro-inflammatory or M2 (immunoregulatory phenotype. Recent evidence suggests that M1 macrophages in diabetic patients may contribute to the complications associated with the disease such as atherosclerosis. Trigonella foenum- graecum (Tfg: fenugreek seeds have been used in traditional medicine in Asia, Africa and the Middle-East for their alleged anti-diabetic properties. Objective: To identify the molecular mechanism(s through which Tfg seeds exert their effects, we investigated the role of a crude methanolic extract of Tfg (FME seeds on macrophage polarization in vitro. Method: THP-1 macrophages (Mϕ were treated with gBSA in the presence/absence of FME and the release and expression of M1 and M2 markers/cytokines were analysed. The role of FME on NF-κB activity was also explored using transfected HEK-293T cells. Results: This study found that the FME significantly (P<0.05 decreased gBSA-induced secretion of M1 cytokines (TNF-α, IL-1β, IL-6 and IL-8 in THP-1 Mϕ cells. In the presence of gBSA, FME also significantly increased the gene expression of the M2 marker Dectin-1, but had no effect on IL-10, IL-1Ra. FME also significantly decreased TNF-α induced NF-kB reporter activity. Conclusion: These results suggest that FME can regulate the expression of M1 and M2 markers in THP-1 Mϕ cells. This may be potentially through the modulation of NF-kB activity. Further work should be carried out to identify precise mechanism(s involved in the effects of FME and Tfg seeds.

    Full Text Available Background: Saponins identified from fenugreek (Trigonella foenum-graecum seeds are reported effective on dyslipidemia. However, the definite mechanism is still not elucidated systematically. In this study, we evaluate the effects of saponin extract on cholesterol absorption, metabolism, synthesis, and reverse cholesterol transport in vivo. Methods: Saponin extract was prepared according to a craft established in our previous study. After the establishment of dyslipidemia model, 40 male Sprague-Dawley rats were divided into five groups, namely the control group (normal diet plus normal saline, HFD group (high fat diet plus normal saline, Lipitor group (high fat diet plus Lipitor (2 mg/kg, and L, M, and H-saponin groups (high fat diet plus saponin in dosages of 6, 12, and 24 mg/kg, respectively. Rats were sacrificed at the end of the 9th week after treatment. Biochemical characteristics of rats were tested, histopathological sections of liver tissue were observed, and the protein and mRNA expression of related factors of cholesterol in the intestine and liver were determined. One-way ANOVA test (SPSS software version 11.5, Chicago, IL, USA was used to determine statistically significant differences between the HFD and other groups. Results: In saponin groups, the serum lipid, bile acid efflux, anti-peroxide activities, and lipid area of liver tissue improved. Cholesterol 7alpha-hydroxylase and scavenger receptor class B type I elevated in the liver. 3-hydroxy-3-methylglutaryl coenzyme A reductase levels were suppressed in both the serum and liver. However, significant cholesterol efflux was not found and Niemann-Pick C1-Like 1 levels elevated in the intestine. Conclusion: The mechanisms of saponin in Fenugreek effect on ameliorating dyslipidemia are probably related to accelerated cholesterol metabolism, inhibited cholesterol synthesis, and facilitated reverse cholesterol transport, but not cholesterol absorption.

    Full Text Available Soluble fiber-rich fenugreek seeds (Trigonella foenum-graecum and garlic (Allium sativum are understood to exert cholesterol-lowering and antioxidant effects. The cardioprotective influence of a combination of fenugreek seeds and garlic by their antioxidant influence was evaluated in hypercholesterolemic rats administered isoproterenol. Wistar rats were maintained on high-cholesterol diet for 8 weeks along with dietary interventions of fenugreek (10%, garlic (2% and their combination. Myocardial infarction was induced with isoproterenol injection. Increased circulatory troponin, disturbed activities of cardiac ATPases, increased serum iron and decreased ceruloplasmin confirmed myocardial infarction. Elevated lipid peroxides accompanied with reduced antioxidant molecules caused by isoproterenol and altered activities of antioxidant enzymes in serum and heart in induced myocardial necrosis were countered by dietary fenugreek, garlic, and fenugreek + garlic. Dietary fenugreek seeds and garlic ameliorated isoproterenol-induced compromised antioxidant status, the cardioprotective effect being higher by the combination of fenugreek seeds and garlic.

    Currently available anxiolytics cause numerous adverse effects and show craving and tolerance during long term treatment. Currently traditional medicines have been re-evaluated widely through work on various plant species. Numerous plants in traditional system show pharmacological activity with unlimited prospective for therapeutic use. Hence we planned to evaluate the effect of methanol extract of T. foenum-graecum L. seeds on anxiety, sedation and motor coordination in mice at different doses following 15 days of oral feeding. Effect on anxiety was assessed by Hole board test and Light and Dark transition models.Phenobarbitone induced sleeping time and Rota rod test were performed to assess effect on sedation and motor coordination. In Hole board test, T. foenum-graecum L. seeds decreased the number of head dips in mice at all the three doses. In Light and Dark transition model, T. foenum-graecum L. seeds increased the period spent in the light box and the number of moves among the two compartments at 100 and 200 mg/kg as compared to control animals. In phenobarbitone induced sleeping time, T. foenum-graecum L. seeds did not reveal any sedative effect. In Rota rod test, extract exhibited significant skeletal muscle relaxant effect at 200 mg/kg (at 90 min) as compared to the control animals. Results of our study shows significant antianxiety effects of T. foenum-graecum L. seeds and may also recommend improved adverse effect profile as compared to diazepam.

    Full Text Available Salinity is one major problem of increasing production in crop growing areas throughout the world. The objective of this research was to evaluate the effect of NaCl priming on seed germination of Tunisian fenugreek (Trigonella foenum-graecum L. under salinity conditions. Seeds of fenugreek were primed with NaCl (4g/l for 36 h in continuous 25°C. Experimental factors were included 2 priming treatments (NaCl and non-priming as control and five salinity solution (4,6,8,10 and 12 gl-1. Results showed that seed priming increased final germination percentage, germination speed and radicle length over the non-primed treatment. At the lowest levels of salinity, there were no notable differences between primed and non-primed seeds, but with increasing salinity levels, primed seeds showed the better performance than non-primed seeds. These results indicated that NaCl priming significantly improved seed performance under salinity conditions.

    Full Text Available Fenugreek (Trigonella foenum-graecum is a medicinal plant which is widely used for its pharmacological properties. In this study the phenolic composition of fenugreek crude seeds originating from Morocco has been investigated. Extraction was performed from defatted seeds by a hydromethanolic solution using an Accelerated Solvent Extractor. HPLC technique coupled to negative ion electrospray ionization mass spectrometry and diode array detection was employed to identify the polyphenol in the obtained extract. The obtained results allowed the detection of 32 phenolic compounds among which various flavonoid glycosides and phenolic acids have been tentatively identified on the basis of their UV and MS spectra, and comparisons with standards when available, as well as with literature data. A systematic study of the obtained MS spectra and the observed fragmentation showed that most of the identified compounds were acylated and non-acylated flavonoids with apigenin, luteolin and kaempferol as aglycons. Hydroxycinnamic acids mostly dominated by caffeic acid derivatives were also detected. The quantitative analysis of the identified compounds showed that the phenolic composition of the studied crude fenugreek seeds was predominantly acylated and non-acylated flavone derivatives with apigenin as the main aglycon.

    Polycystic ovary syndrome (PCOS) is one of the most prevalent hormonal disorders among women of reproductive age causing irregular menstrual cycles, excessive body or facial hair, miscarriage and infertility. The latter being a most common PCOS symptoms. Because the symptoms are seemingly unrelated to one another, PCOS is often overlooked and undiagnosed. The present study is an open label, one-arm, non-randomized, post-marketing surveillance study in 50 premenopausal women (18-45 years, BMIPCOS using a novel Trigonella foenum-graecum seed extract (fenugreek seed extract, Furocyst, 2 capsules of 500 mg each/day) extract, enriched in approximately 40% furostanolic saponins, over a period of 90 consecutive days. The study was conducted to determine its efficacy on the reduction of ovarian volume and the number of ovarian cysts. Ethical committee approval was obtained for this study. Furocyst treatment caused significant reduction in ovary volume. Approximately 46% of study population showed reduction in cyst size, while 36% of subjects showed complete dissolution of cyst. It is important to mention that 71% of subjects reported the return of regular menstrual cycle on completion of the treatment and 12% of subjects subsequently became pregnant. Overall, 94% of patients benefitted from the regimen. Significant increases in luteinizing hormone (LH) and follicular stimulating hormone (FSH) levels were observed compared to the baseline values. Extensive blood chemistry, hematological and biochemical assays demonstrated the broad-spectrum safety. Furocyst caused significant decrease in both ovarian volume and the number of ovarian cysts. Serum ALT, BUN and CK were assessed to demonstrate the broad-spectrum safety of Furocyst. No significant adverse effects were observed. In summary, Furocyst was efficacious in ameliorating the symptoms of PCOS.

    The present study has been carried out to evaluate the radioprotective effect of Trigonella foenum seeds extract (TFE) on peripheral blood of mice. For this purpose, mice were orally given double distilled water (control) or optimum dose (100 mg/kg of body weight per day) of TFE for five consecutive days (experimental). Thirty minutes after the last administration of double distilled water or TFE, these were exposed whole-body to 5 Gy gamma radiation and autopsied between 12 hours to 30 days for hematological and biochemical estimation. Total erythrocyte count, hemoglobin level, and hematocrit percentage were decreased from normal in both the groups. A significant increase in these parameters was observed in TFE administered irradiated group, in contrast to without TFE irradiated one, by restoring towards normal values at the end of the experiment. From the results, it is evident that TFE may be responsible for the protection of stem cells in bone marrow which subsequently resulted in higher hematological constituents in peripheral blood. The study concludes the prophylactic use of such plant extract against radiation induced hematological alterations. (author)

    This study examined the effect of Testofen, a specialised Trigonella foenum-graecum seed extract on the symptoms of possible androgen deficiency, sexual function and serum androgen concentrations in healthy aging males. This was a double-blind, randomised, placebo-controlled trial involving 120 healthy men aged between 43 and 70 years of age. The active treatment was standardised Trigonella foenum-graecum seed extract at a dose of 600 mg/day for 12 weeks. The primary outcome measure was the change in the Aging Male Symptom questionnaire (AMS), a measure of possible androgen deficiency symptoms; secondary outcome measures were sexual function and serum testosterone. There was a significant decrease in AMS score over time and between the active and placebo groups. Sexual function improved, including number of morning erections and frequency of sexual activity. Both total serum testosterone and free testosterone increased compared to placebo after 12 weeks of active treatment. Trigonella foenum-graecum seed extract is a safe and effective treatment for reducing symptoms of possible androgen deficiency, improves sexual function and increases serum testosterone in healthy middle-aged and older men.

    Full Text Available Background: Trigonella foenum-graecum (fenugreek seeds are known to exhibit potent antioxidant, hypoglycemic, and nephroprotective activities, as well as serve as excellent membrane stabilizers especially because of their content of novel furostanolic saponins. Our previous studies exhibited the broad spectrum safety and efficacy of Fenfuro, a novel T. foenum-graecum seed extract enriched in furostanolic saponins, in type 2 diabetes (T2D in rats. Design: This multicenter, randomized, placebo-controlled, double-blind, add-on clinical study evaluated over a period of 90 consecutive days the efficacy of Fenfuro (daily dosage: 500 mg bid in 154 subjects (male: 108; female: 46; age: 25–60 years with T2D. Methods: This study examined the body weight, blood pressure, and pulse rate, as well as the efficacy of Fenfuro on fasting and post-prandial plasma sugar (mg/dL, glycosylated hemoglobin (HbA1c, and fasting and post-prandial C-peptide levels. Results: Fenfuro caused significant reduction in both fasting plasma and post-prandial blood sugar levels. Approximately 83% of the subjects reported decreases in fasting plasma sugar levels in the Fenfuro-treated group as compared to 62% in the placebo group, while 89% of the subjects demonstrated reduction in post-prandial plasma sugar levels in the Fenfuro-treated group as compared to 72% in the placebo group. HbA1c levels were reduced in both placebo and treatment groups. The decrease in HbA1c levels was significant in both groups as compared to respective baseline values. A significant increase in fasting and post-prandial C-peptide levels compared to the respective baseline values was observed, while no significant changes in fasting and post-prandial C-peptide levels were observed between the two groups. No significant adverse effects were observed by blood chemistry analyses. Furthermore, 48.8% of the subjects reported reduced dosage of anti-diabetic therapy in the Fenfuro-treated group, whereas 18

    Full Text Available Fenugreek (Trigonella foenum-graecum L. is a well-known annual plant that is widely distributed worldwide and has possessed obvious hypoglycemic and hypercholesterolemia characteristics. In our previous study, three polyphenol stilbenes were separated from fenugreek seeds. Here, we investigated the effect of polyphenol stilbenes on adipogenesis and insulin resistance in 3T3-L1 adipocytes. Oil Red O staining and triglyceride assays showed that polyphenol stilbenes differently reduced lipid accumulation by suppressing the expression of adipocyte-specific proteins. In addition, polyphenol stilbenes improved the uptake of 2-(N-(7-nitrobenz-2-oxa-1,3-diazol-4-ylamino-2-deoxyglucose (2-NBDG by promoting the phosphorylation of protein kinase B (AKT and AMP-activated protein kinase (AMPK. In present studies, it was found that polyphenol stilbenes had the ability to scavenge reactive oxygen species (ROS. Results from adenosine triphosphate (ATP production and mitochondrial membrane potentials suggested that mitochondria play a critical role in insulin resistance and related signaling activation, such as AKT and AMPK. Rhaponticin, one of the stilbenes from fenugreek, had the strongest activity among the three compounds in vitro. Future studies will focus on mitochondrial biogenesis and function.

    Full Text Available Background Menopause, a natural phenomenon, is defined by the fall of ovarian hormones mainly estrogens causing major problems such as insulin resistance. Fenugreek (Trigonella foenum-graecum is known to have some useful properties such as insulin sensitizing effect. Apelin is an adipokine, which has several roles such as regulation of insulin secretion. Objectives The objective of the present study was to evaluate the effect of fenugreek seed and 17-β estradiol on serum Apelin along with glucose, lipids and insulin in ovariectomized rats. Materials and Methods Forty-nine adult female Wistar rats were randomly divided to seven groups: normal control, ovariectomized control, ovariectomized treated with ethanolic and hexanic extract of fenugreek seed (50 and 150 mg/kg/daily for each, and ovariectomized treated with 17-β estradiol (10 µg/kg/daily for 42 days. Serum Apelin, glucose, lipids and insulin were measured. Results Serum Apelin, glucose, lipids and insulin significantly increased in ovariectomized controls in comparison with normal controls (P < 0.05. Serum glucose, lipids and insulin in ovariectomized rats treated with fenugreek seed extract and 17-β estradiol were remarkably lower than ovariectomized controls (P < 0.05. Furthermore, 17-β estradiol caused a significant decrease (P < 0.05 in serum Apelin in ovariectomized rats. Conclusions It appears that fenugreek seed might be effective against hyperglycemia, hyperlipidemia and insulin resistance in ovariectomized rats without impact on serum Apelin. Furthermore, 17-β estradiol could have similar effects along with possible inhibitory effects on serum Apelin. The complicated role of Apelin in menopause needs to be further explored.

    Full Text Available Copper is one of the heavy metals, although it is an essential microelement through interference with numerous physiological processes, when it absorbed in excess amounts, it can be toxic and induce a number of deleterious effects. A pot experiment was conducted in order to assess the possible effects of Nostoc muscorum (2 g/ kg soil fresh pellets on the growth and some metabolic activities of Trigonella foenum gracum at 30 and 60 days of growth growing under copper stress. This experimental plant was grown in clay-sandy soil (2:1 W/W amended either with different concentrations of CuSO4 (0.4, 0.6, 0.8 and 1.0 g/kg soil or Nostoc mixed with Cu (0.6, 0.8 and 1.0 g/kg soil. Application of Nostoc in a mixture with Cu significantly increased fresh and dry weight of root and shoot, photosynthetic pigments and ctivity at 30 and 60 days of growth when compared with their counterparts of Cu treatment. In addition, the content of K+, Ca2+, P3+ and iron were increased with the exception of a decrease in Cu level at 60 days of growth. On the other hand, the content of starch was significantly decreased at 30 and 60 days of growth. Moreover, the activity of both peroxidase (POD and superoxide dismutase (SOD were reduced by applying Nostoc to the soil having different concentrations of Cu.

    Dietary fenugreek seeds (Trigonella foenum-graecum) and garlic (Allium sativum) have been previously observed to have cardioprotective influence in experimentally induced myocardial infarction in rats. Since low-density lipoprotein (LDL) oxidation is a key factor in the arteriosclerotic process, we evaluated their potential in minimizing the LDL oxidation in rats. Fenugreek seeds, garlic, and their combination were included along with a high-cholesterol diet for 8 weeks. Iron-induced oxidation of LDL in vivo was considerably lowered by dietary fenugreek and garlic. The extent of copper-induced oxidation of isolated LDL in vitro was also significantly lesser in fenugreek-fed or fenugreek+garlic-fed rats. Anodic electrophoretic mobility of the oxidized LDL on agarose gel in case of spice-fed animals was decreased and hence consistent with the observed protective influence on LDL oxidation. Dietary fenugreek, garlic, and their combination significantly lowered lipid peroxide levels in plasma, liver, and heart in iron (II)-administered rats. The results suggest that these two dietary spices have protective effect on LDL oxidation under normal situation as well as in hypercholesterolemic situation. The protective effect of the combination of dietary fenugreek and garlic on LDL oxidation both in vivo and in vitro was greater than that of the individual spices. The protective effect of dietary fenugreek and garlic on LDL oxidation both in vivo and in vitro as evidenced in the present study is suggestive of their cardioprotective potential since LDL oxidation is a key factor in the arteriosclerotic process.

    Full Text Available Abstract Background & aim: Diabetes can affect the spinal cord, an important part of the central nervous system. Fenugreek seed has been suggested to have potential antidiabetic effects. This study was conducted to assess the effects of Fenugreek seed extract (trigonella foenum-graecum on fetal spinal cord structure, specifically in the brachial enlargement cord in an 18-day old fetus of diabetic mothers treated with extracts in comparison with the control groups' mothers. Methods: In the present cross-sectional study, sixteen healthy female rats were randomly divided into four equal groups: Healthy control, Diabetes control, Fenugreek control, Fenugreek treatment. Diabetes was induced by intraperitoneal injection of Streptozotcin (50 mg/kg. All four groups became pregnant by natural mating. After formation of the nervous system, two fetuses from each group were expelled by cesarean after performing anesthesia on the animals on 18th day of pregnancy furthermore their brachial enlargement spinal cord samples were taken. Finally, the tissue sections were prepared by routine procedures and diverse histological parameters were examined. The collected data were analyzed by one-way ANOVA. Results: results showed that fetal body weight on the diabetic control group was significantly higher compared to the other groups (P≤ 0/05. Moreover, significant reductions in the transvers and vertical diameters in central channel of the spinal cord and as well in the number of neurons of the spinal cord gray matter in the diabetic control groups in comparison with the other groups were observed (P≤0/05. Conclusion: The hyperglycemic effect of maternal diabetes during fetal period causes abnormalities, especially in the brachial enlargement of spinal cord, including changes in the spinal cord and neurons number in the gray matter. Disorders occurring in the prenatal remains and may perhaps cause lack of ability to perform certain physical activities. Key words

    Full Text Available Background: Menopause is characterized by the deficiency of ovarian hormones, mainly estrogen. The decline in estrogen hormone is contributing the cardiovascular disorders in women. Hormone replacement therapy has disadvantages especially a higher risk of breast, ovarian and endometrial cancers upon chronic use. Phytoestrogens may be used as an alternative to hormone replacement therapy. Aim and Objectives: This study was designed to scientifically evaluate the role of Choline- Docosahexaenoic Acid (DHA and Trigonella foenum graecum (TFG seed extract on Ovariectomy (OVX induced dyslipidemia and oxidative stress in rat model. Material and Methods: Female Wistar rats were allocated into four groups (n=6:1 Sham control, 2 ovariectomized, 3 ovariectomized+ choline-DHA and 4 ovariectomized + choline-DHA+TFG. After 30 days of treatment, fasting blood samples and liver tissues were collected. Serum was analyzed for lipid profile and liver homogenates were used for assessment of oxidative stress and antioxidant activity. Results: Ovariectomized rats showed significantly increased (P<0.05 Total Cholesterol (TC, Low Density Lipoprotein (LDL levels and decreased High Density Lipoprotein (HDL levels. Treating ovariectomized rats with choline-DHA and TFG seed extract significantly lowered (P<0.05 total cholesterol, LDL and markedly increased the HDL. Significantly increased (P≤0.01 Thiobarbituric Acid Reactive Substances (TBARS and reduced (P<0.05 glutathione levels were observed in OVX group. The synergetic effect of choline-DHA and fenugreek showed a significant reduction ((P≤0.01 in TBARS levels. Conclusion: These results showed that choline-DHA with TFG supplementation have a favorable effect on OVX induced hyperlipidemia and oxidative stress. Therefore, these components may be a therapeutic agent for treating the menopause induced hyperlipidemia or oxidative stress.

    Dry seeds of Trigonella foenum-graecum were exposed to 10, 30 and 60 KR of gamma rays. Germination was observed first in 60 KR followed by 30 KR while in 10 KR and control germination was simultaneous. There was initial stimulating effect of higher doses on root growth and division frequency but after few days both these were negatively correlated with dose. Frequency of abnormal cells increased with dose. Appearance of chromosomal rings is explained on the basis of telomeric losses and intra arm exchange type. At 60 KR there was no growth beyond 2 cotyledonary stage due to adverse effect on cell nuclei in growing region. Differential response of roots, shoots to radiation has been discussed.

    Different diploids of Trigonella foenum-graecum L. and their corresponding autotetraploids were seedtreated with 40 krad of ..gamma..-rays, and parameters such as germination, survival, growth reduction, pollen fertility, pod setting, etc. were recorded. A stimulation of seed germination due to the irradiation could be observed. Contrary to the general rule that polyploids are more radioresistant than their corresponding diploids, one 4x strain was completely killed while the 2x version survived comparatively well. Apparently gene reduplication is not the overall protective mechanism as was once earlier believed. The importance of genotypic influence on radiosensitivity was demonstrated at both the 2x and 4x level. The limitation of interphase chromosome volume and degree of ploidy in predicting radiosensitivity is discussed.

    Full Text Available Abstract Background Various species of genus Trigonella are important from medical and culinary aspect. Among these, Trigonella foenum-graecum is commonly grown as a vegetable. This anti-diabetic herb can lower blood glucose and cholesterol levels. Another species, Trigonella caerulea is used as food in the form of young seedlings. This herb is also used in cheese making. However, little is known about the genetic variation present in these species. In this report we describe the use of ISSR and RAPD markers to study genetic diversity in both, Trigonella foenum-graecum and Trigonella caerulea. Results Seventeen accessions of Trigonella foenum-graecum and nine accessions of Trigonella caerulea representing various countries were analyzed using ISSR and RAPD markers. Genetic diversity parameters (average number of alleles per polymorphic locus, percent polymorphism, average heterozygosity and marker index were calculated for ISSR, RAPD and ISSR+RAPD approaches in both the species. Dendrograms were constructed using UPGMA algorithm based on the similarity index values for both Trigonella foenum-graecum and Trigonella caerulea. The UPGMA analysis showed that plants from different geographical regions were distributed in different groups in both the species. In Trigonella foenum-graecum accessions from Pakistan and Afghanistan were grouped together in one cluster but accessions from India and Nepal were grouped together in another cluster. However, in both the species accessions from Turkey did not group together and fell in different clusters. Conclusions Based on genetic similarity indices, higher diversity was observed in Trigonella caerulea as compared to Trigonella foenum-graecum. The genetic similarity matrices generated by ISSR and RAPD markers in both species were highly correlated (r = 0.78 at p = 0.001 for Trigonella foenum-graecum and r = 0.98 at p = 0.001 for Trigonella caerulea indicating congruence between these two systems

    Full Text Available Summary The levels of the major (Ca, K, Na, Mg, trace (Fe, Cr, Ni, Zn, Mn, Cu, Co, and toxic (Pb, Cd metals in the seeds of fenugreek cultivated in different regions of Ethiopia were determined by flame atomic absorption spectrophotometry (FAAS. Wet ashing was used to digest 0.5 g of fenugreek seed flour using 1.5 mL of HNO3 and HClO4 acid mixtures (5:1 ratio, 30 min pre-digestion time, 45 min total digestion time and a temperature of 150 °C. Thirteen elements were determined, obtaining concentrations in the following ranges: Ca (15353-36771 mg kg-1 > Fe (6041-18584 mg kg-1 ≈ K (6789-11517 mg kg-1 > Pb (615-2624 mg kg-1 > Na (201-1559 mg kg-1 > Cd (285-464 mg kg-1 > Cr (3-552 mg kg-1 > Ni (31-108 mg kg-1 > Mg (31-102 mg kg-1 > Zn (15-33 mg kg-1 > Mn (16-28 mg kg-1 > Cu (ND-35 mg kg-1 > Co (4-15 mg kg-1. A statistical analysis of variance (ANOVA at the 95% confidence level revealed there were significant differences between the mean metal contents of fourteen sample means, except for Zn. Pearson’s correlation revealed weak positive or negative linear relationships, which implies that the presence of one metal did not affect the presence of the other metals within the plant, except for a few metals. The study showed that fenugreek seeds were a good source of essential metals. However, they also contained large amounts of the toxic metals Cd and Pb and therefore should not be consumed daily.

    Full Text Available Background and aim: Diabetes mellitus is associated with some of the metabolic dysfunctions represented with chronic hyperglycemia.  This disease can disrupt the function of testicular tissue and decline male sexual ability. Some of the medicinal herbs such as fenugreeks have protective effects on tissues via hypoglycemic and anti-oxidative properties. In the present paper,  the effects of fenugreek seed extract was evaluated on testicular tissue of 20 day-old embryos from diabetic rats. Methods: In the present experimental study, sixty normal female rats were divided into three normal groups: non-diabetic control, glibenclamide and fenugreek groups and three diabetic groups: diabetic control, glibenclamide treatment and fenugreek treatment groups. Single injection of streptozotocin was used for induction of diabetes in these female rats. After detection of pregnancy, 1000 mg/kg fenugreek seed extract was fed to non-diabetic and diabetic fenugreek groups and 5 mg/kg glibenclamide was fed to non-diabetic and diabetic glibenclamide groups. Non-diabetic and diabetic control group was fed with distilled water as the same volume as the fenugreek extract. After 20 days, their embryos were pulled out and fixed at 10% formalin. After tissue processing, five micron sections were stained with Hematoxylin- eosin and evaluated for morphometric changes of testicular tissue. Data were evaluated with One-Way ANOVA test and Duncan post-hoc test. Results: The mean diameter of seminiferous tubules and testis capsule thickness indicated no significant differences between fenugreek treatment and diabetic control groups (P> 0.05. Mean body weight of male embryos was significantly lower in fenugreek treatment group in comparison with the diabetic control group (P&le 0.05. The leydig, sertoli and spermatogonial cells number was significantly higher in fenugreek treatment group in compression with diabetic control group                      (P

    Full Text Available The 96 genotypes of Trigonella foenum-graecum L. (Fenugreek were estimated by using Sodium Dodecyl Sulphate Poly Acrylamide Gel Electrophoresis (SDS-PAGE. The accessions were maintained from diverse ecological areas of the world. Total seed storage proteins were electrophoresis on 12.5% polyacrylamide gels. A total of 17 protein bands were detected, of which seven were highly polymorphic and six were moderate polymorphic and four were low polymorphic with molecular weight extending from of ~15 to ~180 kDa. The dendrogram based on similarity matrix using Unweighted Pair Group Method with Arithmetic Mean (UPGMA divided all the genotypes into four major clusters i.e., I, II, III and IV comprising 51, 24, 10 and 11 accessions, respectively. Although limited genetic diversity was detected amongst known germplasm but the presence/absence of polymorphic bands revealed a significant variances among different Trigonella genotypes. The differences exposed in this project work should be oppressed for the future breeding prospective of Trigonella genotypes by using other advanced molecular techniques. The SDS-PAGE per se seems inadequate tool for such kind of analysis, and may be integrated with other genetic and sequence based approaches for more precise estimation of the genetic variability within closely related accessions. Our results provide baseline for obtaining locally adapted and improved cultivars of fenugreek in Pakistan.

    2006-03-01

    Full Text Available Fenugreek (Trigonella foenum-graecum L. leaves and seeds have been used extensively for medicinal purposes. Fenugreek seed is known to exhibit anti-diabetic and anti-nociceptive properties and effects such as hypocholesterolaemic, anti-cancer and thyroxine-induced hyperglycaemia. Our research objectives have been to identify the chemical constituent(s responsible for the health effects in human and to develop a strategy for improving these constituents in fenugreek plants. We have observed considerable variability among fenugreek genotypes. They differ in morphology, growth habit, biomass and seed production capability. Chemical constituents of the seed, e.g. saponins, fibre, protein, amino acids and fatty acid contents also differ markedly. This variability is most often overlooked or underestimated in clinical trials. Our research suggests that the genetic variability and the genotype by environmental interaction will play a significant role when the crop is used by the nutraceutical industry in Canada where high quality seed production is at present difficult. Our multi-disciplinary approach aims at understanding the processes involved in the genetic improvement of fenugreek and use the new knowledge to improve the crop. We have developed a fenugreek cultivar "Tristar" for western Canada that can produce very high quality forage and will now concentrate on producing cultivars having improved nutraceutical value. Our research results indicate that the variability for important traits in fenugreek have a genetic base, making selection for improved levels of these traits possible.

    Full Text Available Soil amendments with powdered seeds of Trigonella foenum - graecum (fenugreek caused soil suppressiveness against Meloidogyne javanica. Decomposed seeds of fenugreek caused marked reduction in nematode population densities and subsequent root-knot development as compared to the aqueous extract of the seeds indicating that some indirect factors are involved in the suppression of root-knot nematode. Both decomposed seeds and aqueous extracts enhanced plant height and fresh weights of shoot whereas root growth remained uninfluenced. Changes in fungal communities associated with nematode control were studied by comparing population numbers of fungi in the soil and in internal root tissues (endorhiza in non-amended and fenugreekamended soils. Acremonium sp., Chaetomium globosum, Fusarium solani, Macrophomina phaseolina and Rhizoctonia solani were found to colonize inner root tissues of mungbean. Acremonium sp., C. globosum and F.solani were isolated in a relatively higher frequency from roots growing in the amended soils while M. phaseolina and R. solani colonized greatly in roots growing in non-amended soil. Of the fungi isolated from soils, Penicillium brefaldianum caused maximum juvenile mortality of M.javanica whereas F.solani caused greatest inhibition of egg hatch.

    Full Text Available The crop yield is reduced under saline conditions and this hampers agricultural productivity. The incorporation of plant growth regulators (PGRs during presoaking treatments in many crops has improved seed performance under saline conditions. In order to study the ameliorative effect of plant growth regulators, experiments were conducted to study the variation in organic constituents in the leaves of Trigonella foenum-graecum L. var.PEB, where the seeds were primed with different plant growth regulators and grown under NaCl salinity. After a pre-soaking treatment of six hours in 20 mg L-1 solutions of gibberllic acid (GA3, 6-furfuryladenine (Kinetin and benzyl adenine (BA, the seeds were allowed to germinate and grow for forty-five days under saline conditions. On the analysis of mature leaves, it was observed that chlorophyll a and b, total chlorophyll and protein showed an increase in PGR-treated plants compared to the untreated set. The accumulation of the stress metabolite such as proline and sugars, which increase under saline conditions, showed a significant decrease in the plants pretreated with PGRs.

    Trigonella foenum graecum (fenugreek) is traditionally used to treat. Recent studies suggest that fenugreek and its active constituents may possess anti carcinogenic potential. The preventive efficacy of dietary fenugreek seed 2% and 4% (w/w feed) on diethylnitrosamine-induced rat liver carcinogenesis were evaluated. Rats were sacrificed when rats became very weak with unstable shelf live were chosen as an end point. Egypt is an Islamic country alcoholic prohibition so the possible use of ethanol extraction may be accepted with high restriction towards its applications in human, that it may affect the active constituents of fenugreek seeds. Whereby, fenugreek seeds contain >8% oil, many valuable phenolic compounds, protein and amino acids, etc ... with different concentrations according to the extraction method. So, the present study was carried out to evaluate the effect of fenugreek powder on adult female rats fed experimental diets containing 2% or 4% (w/w) fenugreek seed powder (FSP) for 2 weeks and have phenobarbital in a dose of 200 mg/L ad lib. before and after a single injection with diethylnitrosamine (200 mg/kg body weight). Rats were sacrificed 20 weeks after intra-peritoneal (i.p) diethylnitrosamine injection and their livers, spleens, kidneys and lungs were excised washed well with cold saline, weighted and processed through paraffin wax preparation, staining and pathological changes were examined. It was found that, by comparison with control, continuous feeding of FSP 2% and 4% suppressed hepatocarcinogensity up to 20% and 50%, respectively. In addition, on the basis of these findings, the invaluable and precious fenugreek constituents are diosgenin [(25 R)-5-spirosten-3h-ol] and [5,7-dihydroxy-2-(4-hydroxyphenyl)-6-(3,4,5-trihydroxy-6(hydroxymethyl) tetra- hydro-2H-pyran-2-yl)chroman-4-one] besides, others. Finally, fenugreek seeds seem to have potential role as a novel cancer preventive agent and that needs further investigations

    Full Text Available Introduction Fenugreek (Trigonella foenum-graecum L. is a specific condiment crop mostly grown for its edible parts, and is used as a green fodder and fresh vegetable. The seeds have medicinal value solely against digestive disorders, whereas its leaves are rich source of minerals and nutrients. The growth and yield of fenugreek is particularly affected by the application of nitrogen fertilizer and planting arrangement. Plant growth is a process of biomass accumulation which in turn is derived out of the interaction of the respiration, photosynthesis, water relations, long-distance transport, and mineral nutrition processes. Growth is the most important process in predicting plant reactions to environment. Irradiance, temperature, soil-water potential, nutrient supply and enhanced concentrations of atmospheric carbon dioxide are among some external components influencing crop growth and development. Growth analysis is a useful tool in studying the complex interactions between plant growth and the environment, clarifying and interpreting physiological responses. Plants total dry matter (TDM production and accumulation can be appraised via relative growth rate (RGR and crop growth rate (CGR which are the most important growth indices. Leaf area index (LAI is a factor of crop growth analysis that accounts for the potential of the crop to assimilate light energy and is a determinant component in understanding the function of many crop management practices. Materials and Methods A field investigation was conducted in a paddy field at Shaft County (Guilan Province for eight consecutive months (from November 2009 to June 2010, to study the effect of four levels of nitrogen fertilizer (0, 25, 50 and 75 Kg N ha-1 and four levels of planting density (60, 80,100, and 120 plants m-2 on the growth indices of fenugreek (Trigonella foenum graecum L. crop.

    Alloxan induced diabetic rats were used to evaluate the antihyperglycemic effect of Trigonella Foenum graecum (Fenugreek) and Lupinus Albus (Lupine). The parameters measured during the 45 days oral administration of seeds powder suspension of either Fenugreek or Lupine (1 g/ kg body wt) included: blood glucose, body wt, reduced glutathione content, plasma thiobarbituric acid reactive substances (TEARS), and percentage of glycosylated hemoglobin (HbA), plasma insulin and liver free fatty acids. Fenugreek and Lupine resulted in significant reduction in blood glucose and HbA; restored insulin normal range, ameliorated the contents of glutathione and reduced the increase in the content of plasma TBARS. Lupine at dose of 1 g/ kg body wt exhibited better glucose reduction, restored body wt and free fatty acids concentration than Fenugreek. Diabetes mellitus is the most common disease associated with carbohydrate metabolism, affecting about 200 million people worldwide. Extracts of various plant materials capable of decreasing blood sugar have been tested in experimental animal models (Bopanna and Rathod, 1997). Many unknown and lesser known plants are used in traditional medicinal practices in Egypt. The medicinal values of these plants are not much known to the scientific world. Although herbal medicines have long been used effectively in treating many diseases throughout the world, the mechanism of most of the herbals used has not been defined. Many traditional plant treatments for diabetes are also used, but most of the evidence for their beneficial effects is anecdotal (Jelodar et al., 2005)

    We have recently reported the beneficial modulation of metabolic abnormalities and oxidative stress in diabetic rats by dietary fenugreek seeds and onion. This investigation evaluated the protective influence of dietary fenugreek seeds (100 g kg -1 ) and onion (30 g kg -1 ) on erythrocytes of streptozotocin-induced diabetic rats, through modulation of reduced haematological indices and antisickling potency. This study also evaluated the altered erythrocyte membrane lipid profile and beneficial countering of increased lipid peroxidation, osmotic fragility, along with reduced membrane fluidity and deformability, nitric oxide production and echinocyte formation. Dietary fenugreek seeds and onion appeared to counter the deformity and fragility of erythrocytes partially in diabetic rats by their antioxidant potential and hypocholesterolemic property. The antisickling potency of these spices was accomplished by a substantial decrease in echinocyte population and AGEs in diabetic rats. Further insight into the factors that might have reduced the fluidity of erythrocytes in diabetic rats revealed changes in the cholesterol: phospholipid ratio, fatty acid profile, and activities of membrane-bound enzymes. Dietary fenugreek seeds and onion offered a beneficial protective effect to the red blood cells, the effect being higher with fenugreek + onion. This is the first report on the hemato-protective influence of a nutraceutical food component in diabetic situation. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Full Text Available Purpose. Determination of sowing time effect on productivity of various fenugreek species in the Forest-Steppe zone of Ukraine. Methods. Field study, laboratory test, analytical approach and statistical evaluation. Results. Effect of sowing time on economic characters of common fenugreek (Trigonella foenum graecum L. and blue fenugreek (Trigonella coerulea (Desr. Ser. was investigated. It was found that sowing time significantly influenced the individual productivity of plants and average yield of their fresh and dry matter. In particular, common and blue fenugreek plants formed not only the most developed vegetation but also higher productivity and fresh and dry matter yield, respectively, due to early-spring sowing. In case of summer sowing, the poorest yield of dry matter per unit was obtained for these species caused by a low fresh yield, though the moisture loss index was lower. Conclusions. Common fenugreek is promising for producing “mushroom grass” spices, and the conveyor supply of production in the Forest-Steep zone of Ukraine can be ensured by the first sowing time (the first or the second decades of April and the se­cond sowing time (the third decade of April as during this period more developed vegetation is formed that favored the higher yield of dry matter (1,3–1,5 t/ha.

    Full Text Available The hereby study was based on a factorial experiment conducted in a completely randomized design with four replications, at Agriculture College, Shahrekord University, Iran, in 2014. The role of salicylic acid (SA, potassium nitrate (KNO3 and potassium chloride (KCl was evaluated on seed germination of fenugreek (Trigonella foenum-graecum L. under different cadmium concentrations. Treatments included four levels of seed priming (no priming, potassium chloride, potassium nitrate, salicylic acid and four levels of cadmium concentration (0, 10, 20, 30 mg/L. Cadmium chloride caused a significant inhibition in germination percentage, root elongation, shoot elongation and seedling dry weight. The shoot length was more sensitive to cadmium concentrations than the root length. Primed seeds with SA (100 mg/L proved protection against Cd stress and increased the germination percentage, root elongation, shoot elongation and dry weight of seedlings compared to the control treatment. Seeds treated with SA alleviated the Cd negative effect on germination parameters. In conclusion, using seed priming with salicylic acid can be recommended as a good technique for fenugreek crop on fields exposed to high cadmium toxicity.

    Diabetes mellitus is a group of metabolic diseases characterized by chronic hyperglycemia. Trigonella foenum-graecum (fenugreek) and swimming training have previously been reported to have hypoglycemic and antioxidant effects. We aimed to evaluate the effects of swimming training and fenugreek aqueous extract, alone and in combination, on plasma glucose and cardiac antioxidant enzymes activity of streptozotocin-induced diabetes in rats. We divided 70 male Wistar rats equally into 7 groups: diabetic control (DC), healthy control (HC), swimming (S), fenugreek seed extract (1.74 g/kg) (F1), fenugreek seed extract (0.87 g/kg) (F2), swimming + fenugreek seed extract (1.74 g/kg) (SF1), and swimming + fenugreek seed extract (0.87 g/kg) (SF2). We used streptozotocin for the induction of diabetes. Statistical analyses were performed using the statistical program SPSS. We did not detect any significant differences in body weight in the F1, F2, S, SF1 and SF2 groups compared with the DC group (p>0.05). The results also revealed that the hypoglycemic effect of combined swimming and fenugreek was significantly stronger (pswimming could be useful for the treatment of hyperglycemia and cardiac oxidative stress induced by type 1 diabetes mellitus.

    Full Text Available Antioxidants are naturally occurring substances that combat oxidative damage in biological entities. An antioxidant achieves this by slowing or preventing the oxidation process that can damage cells in the body. It does this by getting oxidized itself in place of the cells. The aim of the present study was to evaluate the in vitro antioxidant and free radical scavenging activities of aqueous and 95% methanol leaf extracts of four herbs viz. Trigonella foenum-graecum L, Murraya koenigii, Coriandrum sativum and Centella asiatica which have frequent use in Indian cuisine. Both aqueous and 95% methanol leaf extracts have shown significant amount reducing power. Both aqueous and 95% methanol leaf extracts of Coriandrum sativum had significant DPPH radical scavenging activity with IC50 value of 0.21± 0.3 mg/L and 0.176 ± 0.008 mg/L respectively. The aqueous leaf extract of Trigonella foenum-graecum L showed low scavenging activity. Among all the leaf extracts, the aqueous leaf extract of Centella asiatica has exhibited significantly high NO radical scavenging activity (80% with IC50 value of 0.11 ± 0.17 mg/L. The aqueous leaf extracts of the samples have showed significantly high superoxide radical scavenging activity. The activity was maximum for the aqueous leaf extract of Centella asiatica, IC50 value is 4.36 ± 0.41 mg/L. anti lipid peroxide activities were very high ( 90 % for aqueous leaf extracts of Coriandrum sativum (IC50 = 0.064 ± 0.85 mg/L and Centella asiatica (IC50 = 0.066 ± 0.9mg/L at a concentration of 0.16 mg/L. The aqueous leaf extracts of the samples were found to contain large amounts of flavonoids and phenolic compounds and exhibited high antioxidant and free radical scavenging activities. These in vitro assays indicate that these plant extracts are significant source of natural antioxidants which might be helpful in preventing the progress of various oxidative stresses.

    Full Text Available The efficacy of aerial parts’ organic extracts of diploid and mixoploid Trigonella foenum-graecum L. plants, harvested at three developmental stages (vegetative, flowering and fruiting was evaluated for their antifungal activity against Fusarium oxysporum f. sp. radicis-lycopersici (FORL and F. oxysporum f. sp. lycopersici (FOL. All tested extracts inhibited FORL and FOL mycelial growth. The organic extracts of diploid plants were found to be less toxic than mixoploid ones and this toxicity varied with the plant developmental stages. The diploids were most toxic, for the two strains, at the fruiting stage; however, mixoploids were more toxic at the vegetative stage for FOL and at flowering one for FORL. FOL was found to be more sensitive to fenugreek extracts when compared to FORL. LC–MS/MS analysis of methanolic extract of fenugreek aerial parts showed eleven different flavonol glycosides (quercetin, kaempferol and vitexin. Five novel components were identified, for the first time in fenugreek aerial parts, as kaempferol 3-O-β-d-glucopyranoside, kaempferol 7-O-glucoside, kaempferol 3-O-α-l-rhamnosyl (1→2 β-d-xyloside, kaempferol 7-O-β-d-glucopyranosyl (1–4 β-d-glucopyranoside and kaempferol 3-O-β-glucosyl (1→2 (6′-O-acetyl-β-d-galactoside, along with other known compounds of this species. To operate with the maximum efficiency, the allelopathic potential of a given plant, our study showed that it would be advisable to identify the most productive developmental stage of allelochemicals. Similarly, it seems that mixoploidy would be a simple and effective biotechnology tool to improve (in quantity and quality the allelochemicals’ production, since the extracts’ toxicity of diploid and mixoploid plants, was different.

    Full Text Available Natural marine polysaccharides such as chitosan, sodium alginate and carrageenan; after depolymerization by different techniques, have shown promising plant growth promoting and other biological activities. Chitosan after irradiation with Co-60 gamma-rays have proven to be a miraculous plant growth promoter in different plants. Trigonelline; an anti-diabetic compound is obtained mainly from the seeds of Fenugreek (Trigonella foenum-graecum L.. Trigonelline counteracts diabetes mellitus (DM through the operation of the mechanisms of insulin secretion, modulation of β-cell regeneration and stimulation of activity of glucose metabolism related enzymes. Considering the medicinal importance a pot experiment was conducted to investigate the effect of foliar application of Co-60 gamma irradiated chitosan (IC with soil applied phosphorus supplement on growth, biochemical and quality attributes of fenugreek. Four concentrations of irradiated chitosan were used (0, 40, 80 and 120 mg L−1 individually as well as in combination with single dose of phosphorus 40 kg ha−1. Un-irradiated chitosan (UN 40 mg L−1 and de-ionized water were used as control. IC significantly affected almost all the parameters including seed yield, trigonelline content and trigonelline yield. There were 10 treatments and among all, P40 + IC 40 mg L−1 proved to be the best, which increased total alkaloid content by 34.9%, seed yield by 125.4%, and trigonelline content by 17.8%. Contents of photosynthetic pigments and activity of nitrate reductase, carbonic anhydrase enzymes were also significantly enhanced.

    Full Text Available Our aim was to determine the antimicrobial activity of three selected plants (Rosmarinus officinalis, Origanum majorana, and Trigonella foenum-graecum against Extended Spectrum Beta Lactamase (ESBL—producing Escherichia coli and Klebsiella pneumoniae— and to identify the specific plant fraction responsible for the antimicrobial activity. The plants were extracted with ethanol to yield the crude extract which was further subfractionated by different solvents to obtain the petroleum ether, the dichloromethane, the ethyl acetate, and the aqueous fractions. The Minimum Inhibitory Concentrations (MIC and Minimum Bactericidal Concentrations (MBC were determined using broth microdilution. The MICs ranged between 1.25 and 80 g/l. The majority of these microorganisms were inhibited by 80 and 40 g/l of the crude extracts. The petroleum ether fraction of Origanum majorana significantly inhibited 94% of the tested strains. Ethyl acetate extracts of all selected plants exhibited relatively low MICs and could be therefore described as strong antibacterial.

    Full Text Available Some ion channels like voltage-operated calcium channels (VOCC within the plasma membrane of vascular muscle cells from the walls of resistance arteries and arterioles play a central role in the regulation of vascular tone. On the basis of reports about the beneficial attenuating effect of fenugreek (Trigonella foenum-graecum L.; TFG on the contractile reactivity of aortic rings of diabetic rats, this study was carried out to evaluate the possible involvement of L-type voltage-operated calcium channels in the vascular effect of this medicinal plant. For this purpose, male Wistar rats were made diabetic using streptozotocin (STZ, 60 mg/Kg, i.p. The extract-treated control and diabetic rats received aqueous leaf extract of TFG (200 mg/Kg, i.p. every other day for two months. At the end of the study, contractile response of isolated aortic rings to KCl and noreadrenaline (NA was determined in the absence and presence of the calcium channel blocker nifedipine. The results showed that aortic rings from diabetic rats are more responsive to the effect of KCl and NA than those of controls, TFG extract treatment could attenuate the enhanced contractile response of aortic rings of diabetic rats, and nifedipine pretreatment could partially neutralize the beneficial effect of this extract. It is concluded that TFG extract attenuates the enhanced vascular reactivity in chronic diabetic rats and voltage-operated calcium channels are in part responsible for this effect of TFG extract.

    The effects of gamma-irradiated sludge on the growth and yield of methi (Trigonella foenum-graecum L.) in pot cultures have been studied. The gamma-irradiated sludge appeared to negatively affect the physical growth parameters of the plant. The significant positive effect of gamma-irradiated sludge was observed on the biochemical growth parameters and yield of methi plants. There was a 3.5-, 1.7- and 2-fold increase in the total protein content, total soluble sugars and starch content, respectively, of plants grown in soil supplemented with gamma-irradiated sludge after 45 days of growth. The gamma-irradiated sludge did not show any detrimental effect on any of the three biochemical parameters studied, even after 90 days of plant growth. The sludge obtained from the conventional treatment process was found to be inhibitory to the protein and starch content of plants in the latter stages of plant growth. A significant increase in the yield of methi plants, after 45 as well as 90 days, grown in the presence of gamma-irradiated sludge indicates a beneficial effect of recycling of irradiated sludge for agricultural applications.

    Full Text Available To study the effects of mycorrhizal inoculation of fenugreek (Trigonella foenum-graecum L. plants and on its growth and yield under drought stress conditions a greenhouse experiment was carried out in split plot using a randomized complete block design at Zabol University green house in 2013. Treatments were three drought stresses: control, mild stress and severe stress (70, 50 and 30% FC assigned to main plots, and three species of mycorrhizal treatments (Glomus intraradices, G. versiform, G. mosseae and non-inoculation as control to sub-plots. The effects of drought on all traits under study were significant, and reduced number of leaves per plant, plant height, root length, chlorophyll b and total chlorophyll by 15.6, 7.6, 10.7, 2.5 and 8.4 % and increased proline and carbohydrates by 38.6 and 17.7 % as compared with the control. Mycorrhizal treatments did not affect the amount of carbohydrates and proline content significantly. Interaction of mycorrhiza and drought stress was significant on grain yield, chlorophyll a and total chlorophyll. Among the mycorrhizal strains G. mosseae affected the traits significantly under drought conditions. The results suggested that mycorrhizal treatments of plants at different drought stresses could improve grain yield of fenugreek and reduce the negative effects of drought by increasing photosynthetic pigments and other quantitative and qualitative traits.

    Full Text Available Introduction: Fenugreek (Trigonalla foenum-graecum L., an annual herbaceous plant belonging to the Coleoidea (Fabaceae family, has numerous medicinal properties such as decreasing blood glucose, laxative, appetizer, mucus, antipyretic and increasing the amount of milk during lactation . Among the most important problems in arid and semi-arid regions, drought stress or water shortage will have negative effects on plant growth. Drought stress occurs mostly because of reducing water availability in the soil. This may be due to excessive water loss or absorption problems, or both of them. One of the major factors limiting germination, which occurs in more arid and semi-arid regions, is salt stress. The study was done to evaluate germination of four Iranian population of fenugreek (Amol, Tabriz, Sari and Mashhad under drought and salinity stresses. Materials and methods: To investigate the effect of salinity and drought stresses on germination and seedling growth characteristics of native landrace fenugreek, two separate experiments were conducted in a Completely Randomized Design with three replications in Seed Laboratory of University of Mashhad in 2014. The experiment treatments consisted of four levels of salinity (0, 60, 120, 180 mM that was induced by different concentrations of sodium chloride and drought stress induced by polyethylene glycol 6000 (PEG 6000 at four levels (0, -3, -6 and -9 Bar with three replications. The drought stress levels were simulation by polyethylene glycol 6000 and using the Michel and Kaufmann formula. Distilled water was applied as control. Iranian seed population of fenugreek were purchased from the city of Amol, Tabriz, Sari and Mashhad then the seeds were washed with sodium hypochlorite (3 % v/v for two minutes for disinfestation and washed three times with distilled water. On the twelfth day of experiment, seedling traits such as plumule and root length and weight in Petri dishes were measured. Results and

The present study was designed to determine the possible protective effect of fenugreek, against {gamma}-radiation-induced oxidative stress in liver and kidney tissues of rats. In parallel, the alteration in the activity of serum alkaline phosphatase (ALP), aspartate aminotransferase (AST) and alanine aminotransferase (ALT), as markers of liver function, creatinine and urea levels as markers of kidney function. In addition, serum glucose and insulin levels were determined as markers for carbohydrate metabolism. Irradiated rats were whole body exposed to 3.5 Gy (Acute dose) {gamma}-radiations. Fenugreek-treated irradiated rats received 1g fenugreek seed powder/kg body weight/day, by gavages, during 7 days before irradiation. Animals were sacrificed on the 1 sl day after irradiation. The results obtained demonstrated that exposure to ionizing radiation induced significant decreases in SOD and CAT activities and GSH content associated to significant increase of TBARS levels in liver and kidney. Fenugreek treatment has significantly attenuated radiation-induced oxidative stress in both tissues, which was substantiated by the significant amelioration of serum ALP, AST and ALT activities, creatinine, urea, glucose, and insulin levels. It could be concluded that fenugreek would protect from oxidative damage and metabolic disturbances induced by ionizing irradiation.

    Full Text Available Introduction: Fenugreek (Trigonella foneum-graecum L. has been cultivated in vegetable farms at the most parts of Iran. It is an annual crop belonging to the Leguminosae family. It originated from west Asia and Iran and cultivated at mostly in European, Asian and African countries, presently. With distinguished of feeding and medicinal values, low needs to soil conditions and its width adaptability to cultivation in different regions, the range of fenugreek cultivation areas have been extended from America to India. In most parts of Iran there is limiting possibilities for cultivation of horticultural and agricultural crops for the reason of limiting water harvesting and unsuitable rainfall distributions. There is no doubt that introduction of new crops for such conditions could increase variation of crops production and stability of farming systems. Plants landraces have been created in thousands of cultivation years under different climatologically and local cropping systems. They are evolved by natural and artificial selection under environmental conditions where they were grown and there have accumulative adaptive genes for tolerance to biotic and abiotic stresses and are the most precious materials in starting of breeding programs. Germination phase is the most important period that guaranties the growth and establishments of crops. One of the basic activators of germination starters is water and limiting of it (drought is the most important retardant of seed growth during germination period under field condition. Fast germination and emergence of seedling from soil and high preliminary growth rate has been known for one of the drought escape mechanisms for most crops such as chickpea, lentil and bean. In breeding programs of crops, using in vitro method is one of the most used methods in germplasm selection for drought tolerance. This study carried out under laboratory condition in order to evaluate some Iranian fenugreek landraces

    Full Text Available Background/objective: The purpose of the present study was to evaluate the effect of fenugreek seed extract in combination with swimming exercise compared to glibenclamide consumption on type 2 diabetic rats. Design: The acute toxicity test was carried out to choose the safe doses and identify the toxicity effects of the fenugreek seed extract. To investigate the hypoglycemic effect of the extract and its effect in combination with swimming training, 80 Wistar Kyoto male streptozotocin-induced diabetic rats were divided randomly into eight groups: diabetic control (C; fenugreek seed extract 0.8 g/kg (F1; fenugreek extract 1.6 g/kg (F2; swimming training (S; swimming training plus fenugreek extract 0.8 g/kg (SF1; swimming training plus fenugreek extract 1.6 g/kg (SF2; glibenclamide (G and swimming training plus glibenclamide (SG. The rats were orally administrated with the treatments once a day with the respective treatment, and the training groups were subjected to swimming training every day for 60 min. Fasting blood samples were collected to measure fasting blood glucose, lipid profile, adiponectin, leptin, and insulin concentrations. Results: The results obtained from acute toxicity study showed no toxicity effect of fenugreek seed extract on the tested dose. Biochemical analysis showed significant improvements in all of the groups compared to the control group (p<0.05. Plasma insulin concentration and insulin resistance (HOMA-IR was significantly reduced in treated groups compared with the diabetic control group. Plasma leptin were significantly decreased in treated groups compared with the control group; while adiponectin had markedly increased (p<0.05. Conclusion: The findings suggest that fenugreek seed consuming, alongside swimming exercise, has a strong therapeutic effect on the improvement of diabetic parameters.

    Studies indicated that 21-day old cotyledons from gamma irradiated seeds of fenugreek beans were heavier and had more starch and sugar than their non-irradiated controls. To test whether these effects occurred in the leaves and to seek a possible biochemical explanation for these results, the activities of five enzymes involved in carbohydrate metabolism were studied. Three groups of fenugreek bean seeds were irradiated (100-300 Gy) and then allowed to grow for 21 days. On harvest, wet and dry weights of both cotyledons and leaves were determined. Starch and sugar contents in cotyledons and leaves were measured. The five enzymes α-amylase, β-amylase, starch phosphorylase, ADPG-pyrophosphorylase and ribulose-1,5-diphosphate carboxylase were extracted from cotyledons and leaves, respectively. The protein contents and activities of the enzyme extracts were determined. The results suggest an increase in carbohydrate metabolism in cotyldeons and a decrease in leaves due to the radiation treatment of the seeds before germination. Thus, increased amounts of starch and sugars are observed in the cotyledons, and decreased amounts in the leaves. Radiation damage to the translocatory system of the plant may retard the movement of sugars from the cotyledons to the other parts of the plant. This may cause accumulation of sugars and starch in the cotyledons, leading to an increase in their size and weight

    Full Text Available Nowadays, the use of soil-born microorganisms as biological fertilizers is considered to be a natural and most desirable solution to maintain sustainability of agricultural soil system. Potassium releasing bacteria, nitrogen fixing and phosphorus dissolving bacteria make mentioned elements available to plants. In order to evaluate the effects of bio-fertilizers Potabarvar 2, Sinorhizobium meliloti, as well as urea fertilizer on physiological properties and yield of Fenugreek, an experiment as complete randomized block design was conducted with five treatments and three replications. Treatments included biofertilizer Potabarvar 2, S. meliloti, inoculation with a mixture of Sinorhizobium+Potabarvar 2, positive control (based on soil analysis and negative control (no fertilization and inoculation.The results showed that all morphological traits were significant at 1%. Most physiological traits except for carotenoid were significantly affected by S. meliloti, and a mixture of Sinorhizobium+Potabarvar 2. Seed inoculation with biofertilizer Sinorhizobium meliloti and Potabarvar 2 lead to increase in growth and eventually shoot yield. Separate application of these biofertilizers led to better results than the integrated application. Symbiotic relationship of Sinorhizobium with Fenugreek increased physiological indices data, especially the absorption of nitrogen and phosphorus, as well as the amount of phenolic antioxidant have been significantly affected. In general, application of S. meliloti resulted in better and more effective increase in yield, quality and plant growth than fertilizer Potabarvar 2 and a mixture of Sinorhizobium+Potabarvar 2.

    Full Text Available Trigonella foenum-graecum L. (Fenugreek is an important plant of the Leguminosae family known to have medicinal properties. However, fraction based antiquorum sensing and antibiofilm activities have not been reported from this plant. In the present study T. foenum-graecum seed extract was sequentially fractionated and sub-MICs were tested for above activities. The methanol fraction of the extract demonstrated significant inhibition of AHL regulated virulence factors: protease, LasB elastase, pyocyanin production, chitinase, EPS, and swarming motility in Pseudomonas aeruginosa PAO1 and PAF79. Further, QS dependent virulence factor in the aquatic pathogen Aeromonas hydrophila WAF38 was also reduced. Application of T. foenum-graecum seed extract to PAO1, PAF79, and WAF38 decreased the biofilm forming abilities of the pathogens by significant levels. The extract also exhibited reduced AHL levels and subsequent downregulation of lasB gene. In vivo study showed an enhanced survival of PAO1-preinfected C. elegans after treatment with extract at 1 mg/mL. Further, the major compound detected by GC-MS, caffeine, reduced the production of QS regulated virulence factors and biofilm at 200 µg/mL concentration indicating its role in the activity of the methanol extract. The results of the present study reveal the potential anti-QS and antibiofilm property of T. foenum-graceum extract and caffeine.

Then the total radiation absorption for each plot was calculated by the relevant equations. Finally, radiation use efficiency is estimated with measuring the slope of the regression line between cumulative absorbed radiation and dry matter of the plant. Results and Discussion The results showed that application of cattle manure increased LAI, particularly in the early stages of Common Mallow growth, and the highest level of LAI was on the treatment of “Nitroxin + SSB + PSB + Cattle manure” and “Chemical fertilizer + cattle manure” with 2.49 and 2.37, respectively. This is while, in the absence of cattle manure, chemical fertilizer had more effect on increasing LAI compared to the biofretilizers. Application of cattle manure also reduced the light extinction coefficient (K of the plant, while “Nitroxin + SSB + PSB + Cattle manure” treatment had the least K value (K=0.47, R2=0.98. ANOVA results showed all experimental treatments had a significant effect (P≤ 0.001 on the cumulative absorbed radiation of Mallow during the growing season. The most accumulated absorbed radiation occurred under Nitroxin + SSB + PSB treatment (by mean of 986.6 MJ.m-2, while application and no-application of cattle manure had no significant effect on radiation absorption. The total calculated mean

    The FSM dispersions revealed shear thinning flow type. Based on colloidal dispersions' rheological properties, five FSM concentrations were taken forward to the lyophilization step. Completely dry and elegant tablets were obtained. Texture analysis indicated highly porous structures, confirmed by SEM analysis, which explain the fast disintegration properties. All the prepared tablets disintegrated in less than 47 s. The disintegration process was prolonged by the increase in FSM content, due to the high viscosity the polymer creates in aqueous media. FSM tablets presented longer disintegration times, as compared to gelatin tablets, but also higher crushing strength. Considering the fast disintegration and the high crushing strength, FSM is a good candidate as matrix forming agent for fast disintegrating dosage forms or other freeze-dried preparations.

    The paper describes the isolation and screening of plant polysaccharides namely tamarind seed polysaccharide (TSP), fenugreek seed mucilage (FSM) and jackfruit seed starch (JFSS) from tamarind (Tamarindus indica L.) seeds, fenugreek (Trigonella foenum-graecum L.) seeds and jackfruit (Artocarpus heterophyllus L.) seeds, respectively. The yields of isolated dried TSP, FSM and JFSS were 47.00%, 17.36% and 18.86%, respectively. Various physicochemical properties like colour, odour, taste, solubility in water, pH and viscosity of these isolated plant polysaccharides were assessed. Isolated polysaccharide samples were subjected to some phytochemical identification tests. FTIR and (1)H NMR analyses of isolated polysaccharides were performed, which suggest the presence of sugar residues. Isolated TSP, FSM and JFSS can be used as pharmaceutical excipients in various pharmaceutical formulations. Copyright © 2015 Elsevier B.V. All rights reserved.

    Fenugreek is a novel forage crop in Canada that is generating interest as an alternative to alfalfa for dairy cows. To evaluate the value of fenugreek haylage relative to alfalfa haylage, six, second lactation Holstein cows (56 ± 8 days in milk), which were fitted with rumen cannulas (10 cm i.d., Bar Diamond Inc., Parma, ID, USA) were used in a replicated three × three Latin square design with 18-day periods. Diets consisting of 400 g/kg haylage, 100 g/kg barley silage and 500 g/kg concentrate on a dry matter (DM) basis were fed once daily for ad libitum intake. The haylage component constituted the dietary treatments: (i) Agriculture and Agri-Food Canada F70 fenugreek (F70), (ii) Crop Development Center Quatro fenugreek (QUAT) and (iii) alfalfa (ALF). DM intake (DMI), milk yield and milk protein and lactose yields were higher (P haylage has a lower feeding value than ALF for lactating dairy cows due in part to lower DMI and subsequently lower milk yield.

    Full Text Available In order to evaluate the effect of salinity on some morphological characteristics and proline content of eight fenugreek landraces and identification of the best landrace, a factorial experiment was conducted on the basis of complete randomized design with three replicates in the research field of Ferdowsi University of Mashhad in 2013. Experimental treatments were combination of eight fenugreek landrace (Isfahan, Tabriz, Hamedan, Sari, Challous, Amol, Mashhad and Yasooj and four levels of salinity stress (0, 60, 120 and 180 Mm NaCl. The ANOVA results revealed the significant effect of salinity on plant height, number of branches/plant, number of nodes, inter nodal distance, root length, shoot length, root dry weight, shoot dry weight, fresh weight of fruit, nut and proline content. The highest level of salinity (180 mM NaCl significantly decreased the mentioned plant characters by 16.72%, 30.44%, 18.22%, 49.45%, 11.95%, 13%, 48.44%, 57.90%, 59.56%, 54.11% compared to control respectively. Proline content in the highest salinity level (180 mM NaCl was increased by 44.57% compared to control. The greatest amount of shoot vegetative yield was obtained from control (without salinity and the highest rate of proline was achieved from 180 Mm treatment.

    Full Text Available Current lifestyle, stress, and pollution have dramatically enhanced the progression of several diseases in human. Globally, scientists are looking for therapeutic agents that can either cure or delay the onset of diseases. Medicinal plants from time immemorial have been used frequently in therapeutics. Of many such plants, fenugreek is one of the oldest herbs which have been identified as an important medicinal plant by the researchers around the world. It is potentially beneficial in a number of diseases such as diabetes, hypercholesterolemia, and inflammation and probably in several kinds of cancers. It has industrial applications such as synthesis of steroidal hormones. Its medicinal properties and their role in clinical domain can be attributed to its chemical constituents. The 3 major chemical constituents which have been identified as responsible for principle health effects are galactomannan, 4-OH isoleucine, and steroidal saponin. Numerous experiments have been carried out in vivo and in vitro for beneficial effects of both the crude chemical and of its active constituent. Due to its role in health care, the functional food industry has referred to it as a potential nutraceutical. This paper is about various medicinal benefits of fenugreek and its potential application as therapeutic agent against several diseases.

    Full Text Available It is known that legumes give benefits to the soil such as improved nutrient availability, improved structure, reduced pest and disease incidence, and hormonal effects (Wani et al., 1995. The major benefit of legume crops comes from biologically nitrogen fixation, deriving from the symbiosis involving leguminous plants and rhizobium bacteria (Vance, 1998. Based on this purpose, a field study was conducted to evaluate radiation absorption and use efficiency in fenugreek and dill in row intercropping as replacement series at the Agricultural Research Station, Ferdowsi University, Ferdowsi University of Mashhad, Iran during growing season of 2013-2014. Treatments included 20% fenugreek+ 80% dill, 40% fenugreek+ 60% dill, 60% fenugreek+ 40% dill, 80% fenugreek+ 20% dill and their monoculture. For statistical analysis, analysis of variance (ANOVA and Duncan’s multiple range test (DMRT were performed using SAS version 9.3 (SAS Institute Inc., Cary, NC, USA. Results indicated that leaf area index, light absorption, total dry matter accumulation and radiation use efficiency (RUE of fenugreek and dill increased in all intercropping ratios compared to monoculture. RUE range for fenugreek was from 0.95 g.MJ-1 in monoculture to 1.24 g.MJ-1 in 40% fenugreek+ 60% dill. RUE range for dill was from 0.64 g.MJ-1 in monoculture to 1.02 g.MJ-1 in 40% fenugreek+ 60% dill.

    Different drying methods due to protein denaturation could alter the functional properties of proteins, as well as their structure. So, this study focused on the effect of different drying methods on amino acid content, thermo and functional properties, and protein structure of fenugreek protein isolate. Freeze and spray drying methods resulted in comparable protein solubility, dynamic surface and interfacial tensions, foaming and emulsifying properties except for emulsion stability. Vacuum oven drying promoted emulsion stability, surface hydrophobicity and viscosity of fenugreek protein isolate at the expanse of its protein solubility. Vacuum oven process caused a higher level of Maillard reaction followed by the spray drying process, which was confirmed by the lower amount of lysine content and less lightness, also more browning intensity. ΔH of fenugreek protein isolates was higher than soy protein isolate, which confirmed the presence of more ordered structures. Also, the bands which are attributed to the α-helix structures in the FTIR spectrum were in the shorter wave number region for freeze and spray dried fenugreek protein isolates that show more possibility of such structures. This research suggests that any drying method must be conducted in its gentle state in order to sustain native structure of proteins and promote their functionalities. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Full Text Available This study investigated the inhibitory effect of aqueous extract of Trigonella foenum-graecum seeds (AqE-TFG on fat accumulation and dyslipidemia in high fat diet- (HFD- induced obese rats. Female Wistar rats were fed with HFD ad libitum, and the rats on HFD were treated orally with AqE-TFG or orlistat ((HFD for 28 days + AqE-TFG (0.5 and 1.0 g/kg or orlistat (10 mg/kg from day 8 to 28, respectively. Treatment with AqE-TFG produced significant reduction in body weight gain, body mass index (BMI, white adipose tissue (WAT weights, blood glucose, serum insulin, lipids, leptin, lipase, and apolipoprotein-B levels and elevation in adiponectin levels. AqE-TFG improved serum aspartate amino transferase (AST, alanine amino transferase (ALT, and lactate dehydrogenase (LDH levels. AqE-TFG treatment reduced the hepatic and cardiac thiobarbituric acid reactive substances (TBARS and elevated the antioxidant enzyme (glutathione (GSH, superoxide dismutase (SOD, and catalase (CAT levels. In addition, liver and uterine WAT lipogenic enzyme (fatty acid synthetase (FAS and glucose-6-phosphate dehydrogenase (G6PD activities were restored towards normal levels. These findings demonstrated the preventive effect of AqE-TFG on fat accumulation and dyslipidemia, due to inhibition of impaired lipid digestion and absorption, in addition to improvement in glucose and lipid metabolism, enhancement of insulin sensitivity, increased antioxidant defense, and downregulation of lipogenic enzymes.

    2012-12-01

    A field experiment was conducted to study the impact of solar UV on root growth and nitrogen fixation in Trigonella foenum-graecum. Plants were grown in iron mesh cages covered with polyester filters that could specifically cut off UV-B (280-315 nm) or UV-A + B (280-400 nm) part of the solar spectrum. The control plants were grown under a polythene filter transmissible to UV. Root biomass, number of nodules and nodule fresh weight were enhanced after exclusion of solar UV. Nitrogenase activity was significantly enhanced by 120% and 80% in the UV-B and UV-A + B excluded plants respectively. Along with nitrogenase there was concomitant increase in leghemoglobin and hemechrome content in the nodules after exclusion of solar UV. These components of sunlight limits nitrogen fixation and their elimination can enhance nitrogen fixation with agricultural advantages like reduction in the use of fertilizers.

    Bathua (Chenopodium album) and fenugreek (Trigonellafoenum graecum) stored in polyethylene bags and without packaging for 24 or 48 hours in a refrigerator at 5 or 30 degrees C in polyethylene bags. The fresh leaves were also dried (oven and sun); blanched (5, 10 or 15 min) and cooked in an open pan and a pressure cooker. The processed leaves were analyzed for total and extractable calcium and zinc content. The Ca and Zn content of these leaves varied from 970 to 2230 and 10.50 to 12.30 mg/100 g DM and the percentage HCl-extractability was 80.34 to 83.04 and 82.43 to 83.90, respectively. Non significant effects of drying and storage were observed on total Ca and Zn content and HCl-extractability while blanching and cooking resulted in significant improvement of HCl-extractability of these two minerals. Thus, cooking and blanching are good ways to improve the HCl-extractability of Ca and Zn.

    The present investigation was conducted to study the effect of selected processing and storage methods on the concentration of ascorbic acid and beta-carotene in Bathua and fenugreek leaves. Methods included storage of leaves with or without polythene bags for 24 and 48 h in a refrigerator at 5 degrees C; at 30 degrees C in polythene bags; drying (sun and oven); blanching (5, 10, 15 min); open pan and pressure cooking. Ascorbic acid content of fresh leaves was 220.97 to 377.65 mg and beta-carotene content was 19.00 to 24.64 mg/100 g, DW. The percent loss of ascorbic acid ranged from 2.03 to 8.77 and 45.15 to 66.9 while lower losses (0.0 to 1.75 and 1.63 to 2.84) of beta-carotene were observed in leaves stored in the refrigerator and at 30 degrees C, respectively. A markedly greater reduction in ascorbic acid and beta-carotene was observed in dried, blanched and cooked leaves. The study data suggest that storage of leaves in refrigeration, drying in oven, blanching for a short time and cooking in a pressure cooker results in better retention of these two vitamins.

    Fenugreek (Trigonella foenum graecum (L.)), is a medicinal plant whose seeds and leaves are widely used in Moroccan traditional medicine. Consumption of fenugreek seeds during pregnancy has been associated with a range of congenital malformations, including hydrocephalus, anencephaly and spina bifida. In previous work we have shown that exposure of pregnant mice to aqueous extract of fenugreek seeds (AEFS) leads to reduced litter size, intrauterine growth retardation, and malformations. However, there have been no studies to date of its longer-term neurobehavioral effects. We investigated these effects in prenatally exposed mice. Pregnant females were exposed to 0, 500 or 1000 mg/kg/day AEFS, by gavage, for the whole period of gestation. Pups body weight was measured at 1, 7, 14, 21 and 28 day of age. Behavior of progeny was evaluated three weeks after birth using the open field, the rotarod test and the continuous alternation task by the T-maze. At 28 postnatal day age, brain of progeny was removed and cut for histological evaluation. The progeny of exposed mice displayed reduced body weight at birth (1000 mg/kg group: 27%; 500 mg/kg group: 32%) and reduced brain weight (10% in both treated groups). Both males and females mice prenatally exposed to AEFS displayed a significant decrease in the locomotor activity, in the boli deposits during the open field test and in motor coordination. These results seem to show that exposure to AEFS induces a depressive effect in the offspring. Assessment on a continuous alternation T-maze test showed a significant reduction in successful spontaneous alternations in males and females but only in the 1000 mg/kg group. These results suggest that prenatal exposure of mice to high dose of fenugreek seeds causes growth retardation and altered neurobehavioral performance in the post-weaning period in both male and female.

    Fenugreek (Trigonella foenum-graecum) is an annual plant from the family of Papilionaceae-Leguminosae that has been credited with many medicinal properties. The current study aims to evaluate the possible fertility activity of fenugreek seeds powder on female and male albino rats. To achieve the theme, fenugreek seeds powder (200 mg/rat) were daily administered orally to both female and male Wistar rats for 15 and 30 consecutive days, after which the rats were sacrificed for both biochemical and histopathological observations. Fenugreek treatment significantly decreased the serum cholesterol levels in both female and male rats with a marked increase in the ovary and testis cholesterol levels following 30 days of consecutive administration. The circulating serum female hormones showed an initial elevation at the end of 15 days of fenugreek intake followed by a significant drop in the group of rats that continued to receive the daily fenugreek dose for 30 days. These observations were supported by the notable decline in the ovarian weights further validated by their ovarian histological sections revealing remarkable dissolution of some follicles and prominent abundance of inflammatory cells. In the 30 days interval treated males, the serum testosterone hormone concentrations significantly declined and the testis weights were reduced with evident damage to the seminiferous tubules and interstitial tissues as shown by the histopathological picture of testis tissue sections. Accordingly, it can be deduced that fenugreek seeds powder exert a significant antifertility adverse effect on the female and male rats when supplemented at a considerable dose for an extended time interval

    Over three million tonnes (t) of tilapia, mostly Nile tilapia (Oreochromis niloticus, L.), are produced annually making it the second most abundantly produced freshwater fish (FAO, 2010). Tilapia are mouthbreeders that often produce stunted populations under pond conditions; one means of prevention is to produce all-male fish with the additional advantage that males usually grow faster than females. All-male populations can be achieved by supplementing feed with androgens such as 17-α-Methylt...

    This study was completed to evaluate the effect of fenugreek seed (Trigonella foenum; FS) and asparagus root (Asparagus officinalis; AR) on in vitro nutrient digestibility and fermentation patterns. Different levels [0%, 5%, 10%, 15% and 20% of dry matter (DM)] of the medicinal plants were included using alfalfa hay (AH) as a basal substrate at different incubation times (12, 18, 24 and 48 h). Total phenolic components of AH, FS and AR were 5.9, 10 and 8.3 g/kg DM, whereas total tannins were 0.4, 3.8 and 1.5 g/kg DM, respectively. Corresponding values for saponins were 10.4, 27.3 and 40.3 g/kg DM. Fenugreek seed increased (pAsparagus root also increased (p<0.05) in vitro OM digestibility and decreased (p<0.05) CP digestibility at different incubation times. Neutral detergent fibre digestibility was increased (p<0.05) by the addition of AR or FS at low levels, but decreased (p<0.05) noticeably by increasing level of two plants in the basal substrate. Ammonia-N concentration was markedly reduced (p<0.05) by the addition of AR at different incubation times, and this reduction was accompanied by the decrease in CP digestibility. True DM degradability and partitioning factor (ratio of substrate DM truly degraded to gas volume produced at different times of incubation) were increased, and total volatile fatty acid concentration and total gas production were decreased (p<0.05) with the addition of FS (at 10% and 15% DM levels) or AR (at 5%, 10% and 15% DM levels) at different incubation times. Results suggest that FS and AR may have potential as feed additives to increase the efficiency of nutrients' utilization, particularly of nitrogen in ruminant diets. © 2012 Blackwell Verlag GmbH.

    Candidiasis is one of the most common opportunistic infections caused by Candida albicans. Fluconazole is the drug of choice for prevention and management of this condition. However, the emergence of fluconazole resistant candidal strains has become a major concern. Many herbs like fenugreek, cinnamon, papaya, oregano, garlic are rich in phytochemical constituents known to express antimycotic activity. With the available information, the present research study was carried out to assess the invitro anti-mycotic activity of hydro alcoholic extracts of Trigonella foenum-graecum seeds, Cinnamomum verum bark and Carica papaya leaves and seeds against fluconazole resistant Candida albicans. Hydro alcoholic extracts of Trigonella foenum-graecum (seeds), Cinnamomum verum (bark), Carica papaya CO.2 strain (male and female leaves) and Carica papaya CO.2 strain (seeds) were prepared by maceration. The anti-mycotic activity of the prepared extracts against Candida albicans was assessed by agar well diffusion method. Three independent experiments were performed in triplicates and the mean and standard deviation were calculated. Minimum inhibitory concentration was determined. The results of the present study revealed that all the extracts exhibited anti-mycotic activity in a dose dependent manner and minimum inhibitory concentration of all the extracts was found to be 15.62 μg/ml. The results of the present study shed light on the fact that plant extracts could be used not only as an alternate drug for management of fluconazole resistant candidiasis but also explored further for oral cancer prevention as a therapeutic adjunct.

The results showed that the germination rate declined after space loading compared to the control group. SP{sub 1} plants grew inhibited first, and then vigorously later at the seedling stage. The branch number, pods and plant weight of SP{sub 1} plants' increased. More important, single pod was changed to dual pod. At the same time, the Fourier transform infrared spectroscopy (FT-IR) was used to analyze and appraise the fenugreek SP{sub 1} seeds. The results indicated that the major components and the structures remained intact, in another word, space mutation had no obvious effect on the quality of SP{sub 1} seeds. Based on the results, some variations mutated by space flight could appear at the present generation. These variations were important to gain high yield. (authors)

    Full Text Available The aim of this study was to compare the effectiveness of Fenugreek (Trigonella foenum-graecum with that of lovastatin in restoration of endothelia function in the aorta taken form aged N-Mair rats. For this purpose, 4 groups of old N-Mari rats were used (n=6, normal saline treated control group, lovastatin (10 mg/kg, orally and fengreek seed powder in normal saline suspension (100 or 500 mg/kg were administered orally daily for 8 weeks. The rate of relaxation of ephedrine- precontracted aorta to acetycholine, the lipid profiles, and histological examinations of the aorta were compared between these two groups and with a control non-treated normal saline treated group. The results showed that treatment with lovastatin and fenugreek produced significant reduction in IDL, VLDL triglyceride and total cholesterol, while HDL was increased as compared to control non-treated group. Lovastatin induced an increase in contraction/mg tissue weight. However, improvement in endothelial function was significantly increased in all treatment groups. The histological findings showed significant reduction in thickness and lipid deposits in the aorta in all treatment groups. The improvement in the epithelial function was correlated with LDL-cholesterol lowering and partly with the reduction in the thickness of the aortic intimal layer. This study demonstrated that fenugreek is as effective as lovastatin in reducing the features associated with atherosclerosis.

    Full Text Available Diabetes mellitus is a public health problem which leads to serious complications over time. Experimentally, many herbs have been recommended for treating diabetes. In most cases, however, the recommendations are based on animal studies and limited pieces of evidence exist about their clinical usefulness. This review focused on the herbs, the hypoglycemic actions of which have been supported by three or more clinical studies. The search was done in Google Scholar, Medline and Science Direct databases using the key terms diabetes, plants, herbs, glucose and patients. According to the clinical studies, Aegle marmelos, Allium cepa, Gymnema sylvestre, Momordica charantia, Ocimum sanctum, Nigella sativa, Ocimum sanctum, Panax quinquefolius, Salacia reticulate, Silybum marianum and Trigonella foenum-graecum have shown hypoglycemic and, in some cases, hypolipidemic activities in diabetic patients. Among them, Gymnema sylvestre, Momordica charantia, Silybum marianum and Trigonella foenum-graecum have acquired enough reputation for managing diabetes. Thus, it seems that physicians can rely on these herbs and advise for the patients to improve management of diabetes.

    This investigation was conducted to study the effect of gamma-radiation doses of 5, 10 and 15 KGy on the microbial and chemical quality as well as antioxidant activity of nine medical plants from 8 plant species grown in Sudan. The plant materials were collected from the country-side of Khartoum State as well as from local markets. Plant parts were selected according to their traditional uses as medicinal plants. Irradiation treatment was carried out or dried ground samples using doses of 5,10, 15 KGy from experimental cobalt-60 gamma source. Plants extracts were prepared using 80% methanol. The control and irradiated samples were analyzed for total bacterial count (cfu/g), secondary compounds, tannin content, total phenol, and antioxidant activity. Tannins, flavonoids, glycosides, anthraquinones, saponin and phenols were evaluated through major compounds in extracts. The total bacterial count indicated that the non- irradiated samples of Trigonella foenum-graecum L., Cassia senna (pods), Cassia senna (leaves), Acacia nilotica L., Brassica nigra L. Koch, Lepidium sativum L., Cymbopogon citratus and Hibiscus sabdariffa L. were highly contaminated with bacteria. The sample of Cymbopogon schoenanthus L. showed a lower count of bacteria (9x10'' 3 Cfu/g), which did not exceed the acceptable level. The samples irradiated with 5, 10 and 15 KGy of gamma radiation dose had significantly lower bacterial counts than the non-irradiated control. The highest sensitivity to gamma rays at 5 KGy dose was observed in Trigonella foenum-graecum L. and Acacia nilotica L. while the lowest sensitivity was in Cymbopogon schoenanthus L. At 15 KGy dose Hibiscus sabdariffa L. and Cymbopogon citratus showed complete absence of microorganisms.

    Full Text Available Fenugreek (Trigonella foenum-graecum L. is one of the oldest medicinal plants. In order to study water-stress effects on some morphological characteristics of fenugreek, an experiment was carried out in a strip plots based on randomized complete blocks design with three replicates, at Research Farm of Shahrekord University, Shahrekord, Iran, in 2010. The first factor was allocated to four water stress levels (irrigation after depletion of 20 (as control, 40, 60 and 80% of available soil moisture and the second factor was six fenugreek landraces (Shiraz, Ardestan, Tirancheh, Yazd, Jahrom and Hindi. The results of ANOVA and comparison of means indicated that the effect of water stress was significant for all traits and variation was observed among landraces for all the studied characteristics. Mean comparison showed that drought stress reduced days to flowering, days to maturity, plant height and yield components (number of pods per plant, number of seeds per pod and 1000-kernel weight. It was also revealed that water stress caused reduction in biological yield (43% and grain yield (42.3% of all genotypes. Comparison between landraces indicated that maximum biological and grain yield belonged to Ardestan landrace. Assessment of cluster analysis showed that it was possible to classify Ardestan, Shiraz and Tirancheh as a single group having tolerance to water stress. In general, based on obtained results, the Ardestan landrace, with 22.37 g/plant, had the highest biological yield and Hindi landrace, with 73.83 days to maturity, was the most early-maturing one.

    Fenugreek ( Trigonella foenum graecum) , a medicinal herb with potent antihyperglycaemic and hypoglycaemic effects, is used to treat diabetes. This study is aimed to explore the interaction of fenugreek seed extract (FSE) and HPT (hypothalamic-pituitary-thyroid) axis in context of leptin secretion which have important role in normal and type-1 diabetic subjects. FSE (confirmed to contain trigonelline, diosgenin, 4 hydroxyisoleucine) was gavaged (0.25 gm/kg body weight/day) to normal and alloxan-induced type-1 diabetic rats for 4 weeks. Expression of hypothalamic prepro-TRH (Thyrotropin releasing hormone) mRNA, serum levels of TRH, TSH (Thyroid stimulating hormone), fT 3 , fT 4 , insulin, leptin, glucose; thyroperoxidase activity and growth of thyroid gland, food intake, adiposity index were also studied FSE significantly down regulated prepro-TRH mRNA expression; decreased serum TRH, TSH, fT 3 , fT 4 levels, and regressed thyroid gland in FSE-fed normal and diabetic rats than those observed in normal diet-fed control and diabetic rats. FSE decreased (psecretion, increased food intake and body weight in all FSE-fed rats. FSE improved insulin secretion, decreased glucose level but impaired HPT axis in diabetic rats, indicating insulin-independent central hypothyroidism. Results suggested that the dominant signal to hypothalamus suppressing HPT axis is the fall in leptin level which i resulted from decreased adiposity index following FSE feeding. Fenugreek simultaneously having hypoglycaemic and hypothyroidal actions raises questions whether it can be safely used to treat diabetes and/or hyperthyroidism as was suggested by many workers. © Georg Thieme Verlag KG Stuttgart · New York.

    soils with the highest sludge dose (20 g kg-1). Soils from the different treatments were potted (5 L) and planted with Trigonella foenum graecum seeds (1 plant per pot). Plants were harvested in the vegetative stage and processed for tissue analysis of Cr, Fe, Zn and Pb. A sequential extraction procedure was applied to the soil for getting insight into the operationally defined soil fractions that incorporate the tannery sludge derived Cr. In any of the treatments Cr was detectable in the exchangeable and easily reducible fractions. In control soils around 10% of soil Cr was in the moderately reducible fraction and the rest in the residual fraction. Contrastingly tannery sludge amended soils incorporated most Cr in the moderately reducible fraction extracted by acid oxalate. This distribution in relation to plant Cr concentrations will be discussed. Acknowledgement: Supported by the Spanish Government (project BFU2010-14873)

    Type 2 diabetes mellitus (T2DM) is a major risk factor for cardiovascular disease, and the prevalence has increased significantly in recent decades to epidemic proportions in China. Individually, fenugreek (Trigonella foenum graecum) seed, mulberry (Morus alba L.) leaf and American ginseng (Panax quinquefolius) root can improve glycemia in various animal models and humans with impaired glucose metabolism and T2DM. The aim of this study was to design an optimized botanical formula containing these herbal extracts as a nutritional strategy for the prevention of insulin resistance and T2DM. Cell-free α-amylase and α-glucosidase enzyme assays were used to determine inhibitory potential of extracts. Glucose uptake was examined in differentiated human adipocytes using radiolabeled 2-deoxyglucose. Male Sprague Dawley rats were divided and glycemia balanced into 5 groups: two controls (naïve and model) and three doses of the botanical test formula containing standardized fenugreek seed, mulberry leaf and American ginseng extracts (42.33, 84.66 and 169.33 mg/kg BW). Insulin resistance and T2DM was induced by feeding animals a high fat diet and with an alloxan injection. Glucose tolerance was examined by measuring serum glucose levels following an oral glucose load. Fenugreek seed and mulberry leaf dose dependently inhibited α-amylase (IC50 = 73.2 μg/mL) and α-glucosidase (IC50 = 111.8 ng/mL), respectively. All three botanical extracts improved insulin sensitivity and glucose uptake in human adipocytes, which lead to the design of an optimized botanical test formula. In a rat model of insulin resistance and T2DM, the optimized botanical test formula improved fasting serum glucose levels, fasting insulin resistance and the development of impaired glucose tolerance. The reduction in epididymal adipose tissue GLUT4 and PDK1 expression induced by high fat diet and alloxan was blunted by the botanical test formula. A novel botanical formula containing standardized

The author will share his life time experience and achievement on induced mutagenesis. The author initiated induced mutagenesis work in 1971 till July 2007 and used both physical (X-ray and Gamma rays) and chemical (EMS, MMS, Colchicine) mutagens for improvement of vegetables (Trichosanthes anguina L, T. cucumarina , Cucurbita maxima L, Cephalandra indica, Luffa acutangula Roxb., Lagenaria ciceraria), medicinal (Trigonella foenum-graecum L, Mentha citrate Ehrh), pulse (Winged Bean (Psophocarpus tetragonolobus L. D.C.), oil bearing (Jatropha curcas L, Rosa damascene, Cymbopogon flexuosus (Nees) Wats) and ornamental (Bougainvillea, Chrysanthemum, Dahlia, Gladiolus, Hibiscus, Lantana depressa Naud, Rose, Tuberose, Narcissus etc.) crops. All classical and advanced mutagenesis methods have been extensively used for the development of new and novel cultivars of economic importance. Early flowering, late flowering, dwarf, yellow fruit color, crinkled leaf, short thick fruit, increased branching, increased pod and seed number, seed size, seed color (green, brown, chocolate color) high fruit-, seed-, oil- and punicic acidyielding mutants have been developed in T. anguina, T. fornum-graecum, Winged Bean and in J.curcas containing 'curcas oil', an efficient substitute fuel for diesel engines. Induction of flower color and chlorophyll variegated mutants in L. depressa proved the efficiency of mutation technique for domestication of wild relatives. Author was deeply engaged for the last 30 years for improvement of ornamentals and has been most successful to produce quite a large number of new promising mutant varieties in different ornamentals. Colchicine has been successfully used to develop new flower color in chrysanthemum and rose and high yielding strains in T. anguina. A novel direct in vitro regeneration technique has

    The extracts and its derived fractions from two important medicinal plants species Trigonella incisa and Nonea edgeworthii were tested for biochemical potential. The aim of our research was to encourage drug finding work with plants. The crude extract and fractions from Trigonella incisa plant were found to be most potent against Pseudomonas aeuriginosa as compared to Escherichia coli and Salmonella typhi. The Chloroform fraction showed outstanding inhibition 11 mm against Pseudomonas aeuriginosa followed by crude extract, n-butanol and aqueous fractions each giving 9 mm inhibition. The n-butanol fraction of Trigonella incisa revealed 8 mm inhibition against Escherichia coli second by aqueous fraction with 7 mm inhibition. Moderate inhibition (8 mm) was showed by crude extract and chloroform fraction against Salmonella typhi. In case of Nonea edgeworthii plant aqueous and ethyl acetate fraction were found to be most active against Pseudomonas aeuriginosa and Escherichia coli giving inhibition of 14 mm each which is found to be best inhibition even more than the inhibition showed by antibiotic used. Crude extract and chloroform fraction of the plant showed 12 mm and 10 mm inhibition against Salmonella typhi. Both the selected plants were found equally potential against the tested fungi. n-hexane and chloroform fractions of Trigonella incisa give 10 mm inhibition against Fusarium oxysporum and Alternaria alternata respectively while crude extract from Nonea edgeworthii give 11 mm inhibition against Alternaria alternata. Over all poor scavenging activity was showed by selected plants. Ethyl acetate fraction of both plants was found to be reasonably good when compared with standard. The low antioxidant profile of the plants may be due to the absence of flavonoids in plants .In preliminary phytochemical screening alkaloid, phenol and saponins were reported in both plants.

    Germinated seedlings from oil seeds (sesame and sunflower) and legumes (Trigonella, Haricot, broad bean and cow pea) were irradiated with gamma rays at doses of 0, 0.2, 0.4, 0.8 and 1 kGy and the data were collected from shoots and roots. Enzymatic activities appeared to be correlated with gamma irradiation dose. The enzymatic activities of irradiated seeds understudy were significantly higher than controls. The peroxidase activities were nearly similar in both roots and shoots, while acid phosphatase activities in roots were higher than in shoots. Also protein contents were higher in roots. The peroxidase and acid phosphatase specific activities in roots were similar. Shoots peroxidase enzymatic activity increased with increased gamma doses. The seedling under study showed two different levels of peroxidase activity, higher as sesame, Trigonella and Sunflower, and lower such as all other legumes understudy. Similar tendency have been also noticed in roots-enzymatic activity, positive correlation between gamma doses treatment and peroxidase enzymatic activity, again two groups higher activity cow pea, broad bean, bean and Trigonella lower such as sesame, such as sesame, sunflower and haircut

    A major feature of all higher eukaryotes is the defined life span of the organism. Radioprotections are substances that protect the cells against Radiation induced damage. Over the past decade interest in evaluating oriental medicinal herbs and edible phytoproducts for use in Cancer preventing strategies is encouraging and emerging as an acceptable approach for controlling the Cancer incidence in many developing countries as well as developed countries. Several experimental evidence has indicated that intake of fruit and vegetables and a number of other dietary items are associated with decreased Cancer incidence. These potential agents either abolish or delay the development of Cancer by interfering with one or more steps in the process of carcinogenesis, such as preventing the activation of carcinogen by increasing detoxification or by blocking the interaction of ultimate carcinogen with cellular macromolecules or suppressing the clonal expansion of neoplastic cells. The potential of using medicinal herbs as Cancer chemo preventive neutraceuticals and functional food is promising. Radioprotective potential of extracts of certain dietary botanicals including Mentha arvensi (field mint), Syzyzium cumini (Jamun), Zingiber officinale (Ginger), Aegle marmelos (Bael), Emblica officianalis (Amla), Aloe vera (Gwar patha), Moringa oleifera (Moringa, Horse Radish Tree), Grewia asiatica (Phalsa), Rosemarinus officinalis (Rosemary), Trigonella foenum-graecum, Ocirnurn sanctum, Phylanthus niruri, Vetiveria zizanioides (vetivergrass), Delbergia sisso oil (Sesame oil) was evaluated. All botanicals tested had shown a very low toxicity. Administration of these botanicals increased the survival of whole body irradiated mice and reduced the symptoms of radiation sickness. (author)

    Full Text Available Vegetables are rich sources of vitamins, minerals, and fibers, and have beneficial antioxidative effects. Ingestion of vegetables containing heavy metals is one of the main routes through which these elements enter the human body. Slowly released into the body, however, heavy metals can cause an array of diseases. In this study we investigated the concentrations of copper, chromium, zinc, and lead in the most frequently consumed vegetables including Pimpinella anisum, Spinacia oleracea, Amaranthus viridis, Coriandrum sativum, and Trigonella foenum graecum in various sites in Raipur city, India. Atomic absorption spectrophotometry was used to estimate the levels of these metals in vegetables. The mean concentration for each heavy metal in the samples was calculated and compared with the permissible levels set by the Food and Agriculture Organization and World Health Organization. The intake of heavy metals in the human diet was also calculated to estimate the risk to human health. Our findings indicated the presence of heavy metals in vegetables in the order of Cr > Zn > Cu > Pb. Based on these findings, we conclude that the vegetables grown in this region are a health hazard for human consumption.

    Full Text Available In this work, we analyzed data from ethnobotanical surveys of functional and nutraceutical legumes (Leguminosae commercialized in the metropolitan area of Buenos Aires, Argentina. The surveys took place in outlets of the general commercial circuit and the restricted circuits belonging to Bolivian and Chinese immigrants. We recorded the species, its products, local therapeutic uses, and available published data on biological activity and effects. Nineteen species were found: Arachis hypogaea var. hypogaea, Cicer arietinum, Glycine max, Lablab purpureus, Lens culinaris, Lupinus albus, L. mutabilis, Medicago sativa, Phaseolus lunatus, P. vulgaris, Pisum sativum, Prosopis alba, Tamarindus indica, Trifolium repens, Trigonella foenum-graecum, Vicia faba, Vigna angularis, V. radiata and V. unguiculata var. unguiculata. Most of these species (15 were found in the general commercial circuit, whereas the rest (4 only in the restricted commercial circuits of immigrants, including L. mutabilis, which deserves a wider diffusion. In most cases, the local uses assigned to a surveyed species correspond to the information available in the literature on the species’ biological activity and effects. This paper provides new insights for ethnobotanical studies and highlights the therapeutic relevance of legumes in the study area.

    Full Text Available The exposure to ultraviolet radiations (UVR is the key source of skin sunburn; it may produce harmful entities, reactive oxygen species (ROS, leading to aging. The skin can be treated and protected from the injurious effects of ROS by using various pharmaceutical formulations, such as cream. Cream can be loaded with antioxidants to quench ROS leading to photo-protective effects. Moreover, modern medicines depend on ethnobotanicals for protection or treatment of human diseases. This review article summarizes various in vivo antioxidant studies on herbal creams loaded with phyto-extracts. These formulations may serve as cosmeceuticals to protect skin against injurious effects of UVR. The botanicals studied for dermatologic use in cream form include Acacia nilotica, Benincasa hispida, Calendula officinalis, Camellia sinensis, Camellia sinensis, Nelumbo nucifera, Capparis decidua, Castanea sativa, Coffea arabica, Crocus sativus, Emblica officinalis Gaertn, Foeniculum vulgare, Hippophae rhamnoides, Lithospermum erythrorhizon, Malus domestica, Matricaria chamomilla L., Moringa oleifera, Morus alba, Ocimum basilicum, Oryza sativa, Polygonum minus, Punica granatum, Silybum marianum, Tagetes erecta Linn., Terminalia chebula, Trigonella foenum-graecum, and Vitis vinifera. The observed anti-aging effects of cream formulations could be an outcome of a coordinating action of multiple constituents. Of numerous botanicals, the phenolic acids and flavonoids appear effective against UVR-induced damage; however the evidence-based studies for their anti-aging effects are still needed.

    Full Text Available Hyperglycemia in diabetic patients results in a diverse range of complications such as diabetic retinopathy, neuropathy, nephropathy and cardiovascular diseases. The role of aldose reductase (AR, the key enzyme in the polyol pathway, in these complications is well established. Due to notable side-effects of several drugs, phytochemicals as an alternative has gained considerable importance for the treatment of several ailments. In order to evaluate the inhibitory effects of dietary spices on AR, a collection of phytochemicals were identified from Zingiber officinale (ginger, Curcuma longa (turmeric Allium sativum (garlic and Trigonella foenum graecum (fenugreek. Molecular docking was performed for lead identification and molecular dynamics simulations were performed to study the dynamic behaviour of these protein-ligand interactions. Gingerenones A, B and C, lariciresinol, quercetin and calebin A from these spices exhibited high docking score, binding affinity and sustained protein-ligand interactions. Rescoring of protein ligand interactions at the end of MD simulations produced binding scores that were better than the initially docked conformations. Docking results, ligand interactions and ADMET properties of these molecules were significantly better than commercially available AR inhibitors like epalrestat, sorbinil and ranirestat. Thus, these natural molecules could be potent AR inhibitors.

    Full Text Available Diabetes mellitus is one of the most common and complex problems of modern societies which has caused many economic and social problems. Because diabetes has no definite treatment, the use of traditional medicine seems to be an appropriate solution to control and manage it. Studies revealed that Vaccinium Arctostaphylos L., Securigera securidaca L., Gymnema sylvestre L., Atriplex halimus L., Camellia sinensis L., Ginkgo biloba L., Mamordica charantia L., Citrullus colocynthis (L. Schrad., Allium cepa L., Allium sativum L., Silybum marianum (L., Gaertn and Trigonella foenum graecum L. are effective against diabetes. Flavonoids, quercin, metformin, quinolizidine, anthocyanin, catechin and flavone, phenylpropanoids, lipoic acid and coumarin metabolites were introduced major impact on diabetes. With regard to the study of plants and their metabolites and the mechanisms of their influence, it is clear that these plants have the potential to reduce blood sugar and diabetes and be considered as candidates for preparing new drugs. Combination of plants extracts or their components may also have synergistic effects to better act on diabetes.

    The work reported here deals with the study of interception and translocation of airborne 131 I in fenugreek (Trigonella foenum-graecum) and okra (Hibiscus esculentus), two very common vegetables in India. Activity was injected into the experimental chamber in the form of iodide aerosols having a size distribution of 0.3 to 5.0 μm (AMAD). Samples of plants were collected over a period of a few days at different time intervals after injection of the aerosols. Evaluation of interception with deposition and translocation of 131 I was done from the activity measured in air and in plant parts. For the deposition factor, the values are 1.22 m 3 kg -1 for fenugreek leaves, and 1.49 m 3 kg -1 for the plant as a whole. For okra plants these values are 0.02 and 0.16 m 3 kg -1 in edible okra and leaves, respectively. For the okra plant as a whole, the value is 0.19 m 3 kg -1 . The translocation factors vary from 0.62 to 0.86 and 0.47 to 0.87 for leaves and stem, respectively, in the case of fenugreek plants. For okra plants, the translocation factor varies from 0.21 to 0.82, 0.53 to 0.93, and 0.42 to 0.81 in edible okra, leaves, and stems, respectively. 13 refs., 6 figs., 2 tabs

    In order to select the main medicinal plants used in folk medicine to treat arterial hypertension and/or diabetes, a survey was undertaken in different areas of oriental Morocco. The patients (370 women and 256 men) were divided into three groups: diabetics (61%), hypertensives (23%) and hypertensive diabetic persons (16%). On average, 67.51% of patients regularly use medicinal plants. This proportion is perceptibly the same in all groups and does not depend on sex, age and socio-cultural level. This result shows that phytotherapy is widely adopted in northeastern Morocco. For diabetes, 41 plants were cited, of which the most used were Trigonella foenum-graecum L. (Leguminosae), Globularia alypum L. (Globulariaceae), Artemisia herba-alba Asso. (Compositae), Citrullus colocynthis (L.) Schrad. (Cucurbitaceae) and Tetraclinis articulata Benth. (Cupressaceae). In the hypertension's therapy 18 vegetal species were reported, of which the most used were Allium sativum L. (Liliaceae), Olea europea L. (Oleaceae), Arbutus unedo L. (Ericaceae), Urtica dioica L. (Urticaceae) and Petroselinum crispum A.W. Hill (Apiaceae). Among the 18 species used for hypertension, 14 were also employed for diabetes. Moreover, these two diseases were associated in 41% of hypertensives. These findings suggest that hypertension observed in this region would be in a large part related to diabetes.

    Botanical products are widely used in nutritional supplementation for promotion of health or prevention of diseases. With the high prevalence of obesity and type 2 diabetes, abnormalities in carbohydrate metabolism are common in the general population and obtaining glycemic control is important in reducing the complications of diabetes. If shown to be effective, botanical products have a unique position in potentially aiding the general public in regard to obesity and diabetes. They can be obtained "over-the-counter" and may have less side effects compared to many synthetic drugs. Although most of the popular botanicals have a long history in folk medicine, there is paucity of data regarding their efficacy and safety, particularly as it relates to human studies. In this review, we discuss the data that was available in the literature for nine botanicals that are frequently promoted to help manage blood glucose. They are Bitter Melon (Momordica charantia), Fenugreek (trigonella foenum graecum), Gymnema Sylvestre, Ivy Gourd (Coccinia indica), Nopal or Prickly Pear Cactus (Opuntia streptacantha), Ginseng, Aloe Vera, Russian Tarragon (Artemisia dracunculus), and Garlic (Allium sativum). The discussion is emphasized on the clinical aspect of these botanicals. Due to the lack of sufficient evidence from clinical studies for any of the botanicals reviewed, it is premature to actively recommend use of any particular herb to treat either glucose or other risk factors. Thus, well defined randomized clinical trials are warranted in this area.

    India is currently facing the silent epidemic of ischemic heart disease, type 2 diabetes mellitus (T2DM), hypertension, and stroke. Both diabetes and ischemic heart disease appear in Indian people a decade earlier compared to whites. The recent evidence that certain medicinal plants possess hypoglycemic, lipid-lowering, and immunomodulating properties on account of their rich flavonoid and/or other glucose-lowering active constituents merits scientific scrutiny in this regard. The present communication aims to give a brief review of those plants that could be useful in T2DM associated with hypertension, ischemic heart disease, and/or dyslipidemia. Aegle marmelos (bael), Allium sativum (garlic), Curcuma domestica (turmeric), Eugenia jambolana (jamun), Murraya koenigii (curry leaves), Trigonella foenum graecum (fenugreek), and Terminalia arjuna (arjun) have been found to be useful in diabetes associated with ischemic heart disease. Their active biomolecules have been identified. They have also been demonstrated to be safe in long-term use. Further clinical research regarding their potency and efficacy vis-à-vis oral hypoglycemics needs to done.

    Long term alcohol consumption is one of the important causes for liver failure and death. To complicate the existing problem there are no dependable hepatoprotective drugs and a large number of patients prefer using complementary and alternative medicines for treating and managing hepatic complications. Almost 25 centuries ago, Hippocrates, the father of medicine, proclaimed "Let food be thy medicine and medicine be thy food." Exploring the association between diet and health continues even today. Preclinical studies carried out in the recent past have shown that the commonly used dietary agents like Allium sativum (garlic), Camellia sinensis (tea), Curcuma longa (turmeric), Emblica officinalis (Indian gooseberry), Ferula asafoetida (asafoetida), Garcinia cambogia (Malabar tamarind), Glycine max (soyabean), Murraya koenigii (curry leaves), Piper betle (beetle leaf), Prunus armeniaca (apricot), Ocimum gratissimum (wild basil), Theobroma cacao (cocoa), Trigonella foenum-graecum (fenugreek) and Vitis vinifera (grapes) protect against ethanol-induced hepatotoxicity. Mechanistic studies have shown that the beneficial effects of these phytochemicals in preventing the ethanol-induced hepatotoxicity are mediated by the antioxidant, free radical scavenging, anti-inflammatory and anti-fibrotic effects. The present review for the first time collates the hepatoprotective effects of these agents and also emphasizes on aspects that need future research to establish their utility in humans.

    The usage of medicinal plants is traditionally rooted in Bangladesh and still an essential part of public healthcare. Recently, a dramatically increasing prevalence brought diabetes mellitus and its therapy to the focus of public health interests in Bangladesh. We conducted an ethnobotanical survey to identify the traditional medicinal plants being used to treat diabetes in Bangladesh and to critically assess their anti-diabetic potentials with focus on evidence-based criteria. In an ethnobotanical survey in defined rural and urban areas 63 randomly chosen individuals (health professionals, diabetic patients), identified to use traditional medicinal plants to treat diabetes, were interviewed in a structured manner about their administration or use of plants for treating diabetes. In total 37 medicinal plants belonging to 25 families were reported as being used for the treatment of diabetes in Bangladesh. The most frequently mentioned plants were Coccinia indica, Azadirachta indica, Trigonella foenum-graecum, Syzygium cumini, Terminalia chebula, Ficus racemosa, Momordica charantia, Swietenia mahagoni. Traditional medicinal plants are commonly used in Bangladesh to treat diabetes. The available data regarding the anti-diabetic activity of the detected plants is not sufficient to adequately evaluate or recommend their use. Clinical intervention studies are required to provide evidence for a safe and effective use of the identified plants in the treatment of diabetes.

    Hyperglycemia in diabetic patients results in a diverse range of complications such as diabetic retinopathy, neuropathy, nephropathy and cardiovascular diseases. The role of aldose reductase (AR), the key enzyme in the polyol pathway, in these complications is well established. Due to notable side-effects of several drugs, phytochemicals as an alternative has gained considerable importance for the treatment of several ailments. In order to evaluate the inhibitory effects of dietary spices on AR, a collection of phytochemicals were identified from Zingiber officinale (ginger), Curcuma longa (turmeric) Allium sativum (garlic) and Trigonella foenum graecum (fenugreek). Molecular docking was performed for lead identification and molecular dynamics simulations were performed to study the dynamic behaviour of these protein-ligand interactions. Gingerenones A, B and C, lariciresinol, quercetin and calebin A from these spices exhibited high docking score, binding affinity and sustained protein-ligand interactions. Rescoring of protein ligand interactions at the end of MD simulations produced binding scores that were better than the initially docked conformations. Docking results, ligand interactions and ADMET properties of these molecules were significantly better than commercially available AR inhibitors like epalrestat, sorbinil and ranirestat. Thus, these natural molecules could be potent AR inhibitors.

    Full Text Available Abstract Background This study was conducted to identify medicinal plants and spices used for medicine by the community of Beni-Sueif, Upper Egypt. Methods Ethnobotanical data from local people was collected using direct interviews and a semi-structured questionnaire. Results Forty-eight plant species belonging to twenty-seven families and forty-seven genera were encountered during the study. Their botanical and vernacular names, plant parts used and medicinal uses are given. Results of the study were analyzed using two quantitative tools. The factor informant consensus indicated the agreement in the use of plants and the fidelity level indicated the ratio between the number of informants who independently suggested the use of a species for the same major purpose and the total number of informants who mentioned the plant for any use. The results of the factor informant consensus showed that the cardiovascular category has the greatest agreement, followed by the immunological, gastrointestinal and respiratory categories. The most important species according to their fidelity are: Hibiscus sabdariffa L. for the cardiovascular category; Trigonella foenum-graecum L. for the immunological category; Mentha piperita L. for the gastrointestinal category and Pimpinella anisum L. for the respiratory category. Conclusions Medicinal plants are still used for treatment in Beni-Sueif community despite the availability of prescribed medications. Documentation of this ethnomedicinal knowledge is important. Evaluation of pharmacological activity for the promising medicinal plants is suggested.

    The objective of the study was to investigate the influence of dehydration on nutrient composition of Amaranthus gangeticus, Chenopodium album, Centella asiatica, Amaranthus tricolor and Trigonella foenum graecum. The green leafy vegetables (GLV) were steam blanched for 5 min after pretreatment and dried in an oven at 60 °C for 10-12 h. The fresh and dehydrated samples were analyzed for selected proximate constituents, vitamins, minerals, antinutrients and dialyzable minerals. Dehydration seems to have little effect on the proximate, mineral and antinutrient content of the GLV. Among the vitamins, retention of ascorbic acid was 1-14%, thiamine 22-71%, total carotene 49-73% and β-carotene 20-69% respectively, of their initial content. Dialyzable iron and calcium in the fresh vegetables ranged between 0.21-3.5 mg and 15.36-81.33 mg/100 g respectively, which reduced to 0.05-0.53 mg and 6.94-58.15 mg/100 g on dehydration. Dehydration seems to be the simplest convenient technology for preserving these sources of micronutrients, especially when they are abundantly available. Irrespective of the losses of vitamins that take place during dehydration, dehydrated GLV are a concentrated natural source of micronutrients and they can be used in product formulations. Value addition of traditional products with dehydrated GLV can be advocated as a feasible food-based approach to combat micronutrient malnutrition.

    Biologic based therapies are frequently used as complementary medicines in diabetes. The aim of this study was to identify the commonly used herbal remedies and their preparations in Sri Lankan patients with Type 2 diabetes. This is a descriptive, cross-sectional study on 220 diabetic patients using herbal remedies for perceived glycemic benefit. All the patients used their regular conventional medications together with herbal remedies. The most commonly used medication was metformin (91.4%). Ivy gourd (Coccinia grandis) was the most commonly used herbal remedy (32%), followed by crepe ginger (Costus speciosus) (25%) and bitter gourd (Momordica charantia) (20%). Herbal remedies used less frequently were finger millet (Eleusine corocana) (5%), anguna leaves (Wattakaka volubilis) (5%), goat weed (Scoparia dulcis) (4%), Salacia reticulata (4%), fenugreek (Trigonella foenum-graecum) (3%) and tree turmeric (Coscinium fenestratum) (0.5%). None of the patients used commercially available over-the-counter herbal products. The common preparations were salads (72.8%), curries (12.8%), herbal tea (6%), and herbal porridges (6%). The practice of using household ingredients as complementary medicines is common in Sri Lanka. Few herbal remedies and their methods of preparation have limited evidence for efficacy. In view of the frequent use by diabetic patients each needs to be documented for reference and scientifically explored about their hypoglycemic potential.

    Vivabon syrup is a balanced composition of dietary ingredients of phytopharmaceutical nature for maintaining the physique, vigor, vitality and balanced growth of children. The herbal ingredients of pediatric syrup are rich in bioflavonoid, proteins, vitamins, glycosides and trace elements. Vivabon is formulated with herbal drugs such as Phoenix sylvestris, Emblica officinalis, Withania somnifera, Centella asiatica, Amomum subulatum, Zingiber officinalis, Trigonella foenum-graecum, Centaurea behen and Piper longum Catechins are flavan-3-ols that are found widely in the medicinal herbs and are utilized for anti-inflammatory, cardio protective, hepato-protective, neural protection and other biological activities. In general, the dietary intake of flavonoids has been regarded traditionally as beneficial for body growth. Standardization of Vivabon syrup dosage form using HPLC/DAD has been developed for quantitative estimation of Catechin as a chemical marker. The method was validated as per ICH guidelines. Validation studies demonstrated that the developed HPLC method is quite distinct, reproducible as well as quick and fast. The relatively high recovery and low comparable standard deviation confirm the suitability of the developed method for the determination of Catechin in syrup. © The Author 2016.

    2015-03-01

    Metabolic syndrome and its complications continue to rise in prevalence and show no signs of abating in the immediate future. Therefore, the search for effective treatments is a high priority in biomedical research. Products derived from botanicals have a time-honored history of use in the treatment of metabolic diseases including type 2 diabetes. Trigonella foenum-graecum, commonly known as fenugreek, is an annual herbaceous plant that has been a staple of traditional herbal medicine in many cultures. Although fenugreek has been studied in both clinical and basic research settings, questions remain about its efficacy and biologic mechanisms of action. Diosgenin, 4-hydroxyisoleucine, and the fiber component of the plant are the most intensively studied bioactive constituents present in fenugreek. These compounds have been demonstrated to exert beneficial effects on several physiologic markers including glucose tolerance, inflammation, insulin action, liver function, blood lipids, and cardiovascular health. Although insights into the molecular mechanisms underlying the favorable effects of fenugreek have been gained, we still do not have definitive evidence establishing its role as a therapeutic agent in metabolic disease. This review aims to summarize the currently available evidence on the physiologic effects of the 3 best-characterized bioactive compounds of fenugreek, with particular emphasis on biologic mechanisms of action relevant in the context of metabolic syndrome. © 2015 American Society for Nutrition.

    EPR spectral investigations have been carried out on four edible leafy vegetables of India, which are used as dietary component in day to day life. In Rumex vesicarius leaf sample, EPR spectral investigations at different temperatures indicate the presence of anti-ferromagnetically coupled Mn(IV)-Mn(IV) complexes. EPR spectra of Trigonella foenum graecum show the presence of Mn ions in multivalent state and Fe 3+ ions in rhombic symmetry. EPR spectra of Basella rubra indicate the presence of Mn(IV)-O-Mn(IV) type complexes. The EPR spectra of Basella rubra have been studied at different temperatures. It is found that the spin population for the resonance signal at g = 2.06 obeys the Boltzmann distribution law. The EPR spectra of Moringa oliefera leaves show the presence of Mn 2+ ions. Radiation induced changes in free radical of this sample have also been studied. The FT-IR spectra of Basella rubra and Moringa oliefera leaves show the evidences for the protein matrix bands and those corresponding to carboxylic C dbnd O bonds.

    Full Text Available Genetic defects during spermatogenesis can lead to a reduction in sperm motility and cause male infertility. The cation channels of sperm (CatSper play a role in the regulation of hyperactivated sperm motility in mouse testes. The effect of Trigonellae Semen (TS on the male reproductive system and CatSper protein in mouse testes during spermatogenesis was examined. C57BL/c mice were divided into the following five groups: normal, cyclophosphamide- (CP- only treated (control group, and three groups treated with varying concentrations of TS with CP (100, 500, and 1000 mg/kg TS and 100 mg/kg CP. Real-time PCR, western blot analysis, and a testosterone immunoassay were performed to assess CatSper protein levels in the five groups. Additionally, sperm cell counts and motility were examined. Results indicate that sperm motility and sperm counts increased in the TS treated groups in a dose-dependent manner (p<0.01. CatSper levels were also significantly higher in the TS treated groups compared to that of the control group (p<0.001. Therefore, TS treatment could enhance sperm function by promoting spermatogenesis and the expression of CatSper proteins in mouse testes.

    Agricultural robotics has received attention for approximately 20 years, but today there are only a few examples of the application of robots in agricultural practice. The lack of uptake may be (at least partly) because in many cases there is either no compelling economic benefit......, or there is a benefit but it is not recognized. The aim of this chapter is to quantify the economic benefits from the application of agricultural robots under a specific condition where such a benefit is assumed to exist, namely the case of early seeding and re-seeding in sugar beet. With some predefined assumptions...... with regard to speed, capacity and seed mapping, we found that among these two technical systems both early seeding with a small robot and re-seeding using a robot for a smaller part of the field appear to be financially viable solutions in sugar beet production....

    Full Text Available Introduction Iran is among the countries with a climate appropriate for growing a wide range of herbs, and can be a great source of producing and exporting plants. Fenugreek (Trigonella foenum gracum is one of the oldest plant and it is an annual herbaceous plant of the Fabaceae family (Fabaceae which are dry, brown or reddish-yellow to gray to over 5.3 mm. Seeds of this plant are used as a spice and its leaves are used as a vegetable. Among the most important factors in farming, it is important to use appropriate planting density. Therefore, if all the necessary conditions, including the right, but density is inappropriate, it will not get the optimum yield per unit area. The effective management of weeds increase the performance of weed management practices, reduce weed population and the costs associated with it over time. Weeds compete with crops for a variety of sources such as light, water and minerals. Given that the best time weeding the weeds and the most appropriate density of fenugreek is not much information available, this study aimed to determine the appropriate density of weed infested and fenugreek was used. Materials and Methods In order to determine the effects of weed interference and appropriate density of fenugreek, a field trial was conducted in research farm of Birjand Islamic Azad University during the spring of year 2011. The experiment was a factorial based on randomized complete block design. The treatments were fenugreek density at 10, 20 and 40 plants m-2 and weed interference in five levels included weed-free to maturity, 20, 40 and 60 days after emergence, and no weeding. Fenugreek seeds (spherical, brown of pure seed before planting desert of preparation and sterilization by benomyl and then do planting trees and irrigation was done immediately.

    Full Text Available Abstract Background Various therapeutic effects of fenugreek (Trigonella foenum-graecum L. on metabolic disorders have been reported. However, the bitterness of fenugreek makes it hard for humans to eat sufficient doses of it for achieving therapeutic effects. Fenugreek contains bitter saponins such as protodioscin. Fenugreek with reduced bitterness (FRB is prepared by treating fenugreek with beta-glucosidase. This study has been undertaken to evaluate the effects of FRB on metabolic disorders in rats. Methods Forty Sprague–Dawley rats were fed with high-fat high-sucrose (HFS diet for 12 week to induce mild glucose and lipid disorders. Afterwards, the rats were divided into 5 groups. In the experiment 1, each group (n = 8 was fed with HFS, or HFS containing 2.4% fenugreek, or HFS containing 1.2%, 2.4% and 4.8% FRB, respectively, for 12 week. In the experiment 2, we examined the effects of lower doses of FRB (0.12%, 0.24% and 1.2% under the same protocol (n = 7 in each groups. Results In the experiment 1, FRB dose-dependently reduced food intake, body weight gain, epididymal white adipose tissue (EWAT and soleus muscle weight. FRB also lowered plasma and hepatic lipid levels and increased fecal lipid levels, both dose-dependently. The Plasma total cholesterol levels (mmol/L in the three FRB and Ctrl groups were 1.58 ± 0.09, 1.45 ± 0.05*, 1.29 ± 0.07* and 2.00 ± 0.18, respectively (*; P P P  Conclusions Thus we have demonstrated that FRB (1.2 ~ 4.8% prevents diet-induced metabolic disorders such as insulin resistance, dyslipidemia and fatty liver.

    The application of radiation biology has gained greater relevance and significance in health and environmental issues. In the present time, nuclear terrorism and weapon related effects are raising much alarm and concern to public health. Obviously, radiation biology research has great potential in diagnosis, therapy and establishing standards for assessment risk from radiation exposure. The development of effective medical countermeasures against nuclear biological and chemical weapons is of immense importance to the defense of all nations and especially to those threatened by international terrorism. Chemical radiation protection is an important strategy to protect living being against deleterious effects of radiation. Earlier the synthetic chemical substances, which could minimize the pathological changes in the living system after exposure to ionizing radiation, were looked into. Medicinal plants are the local heritage with global importance. World is enclosed with a rich wealth of medicinal plants. Herbs have always been the principle form of medicine in India and presently they become popular. Over the last few years, interest in evaluating oriental medicinal herbs and edible phyto products for the use in anti-radiation strategies is encouraging and emerging as an acceptable approach for preventing the radiation induced lesions in many countries. Several Indian medicinal plants (Emblica officinalis, Rosemarinus officinalis, Trigonella foenum-graecum, Alstonia scholaris, Tinospora cordifolia, Phyllanthus niruri, Syzygium cumini, Aegle marmelos, Panax ginseng, Linum usitatissimum, Delonix regia etc) and antioxidant vitamins (C and E) have been tested in this laboratory by taking various biological end points for the possible use of natural products and phytochemicals to serve as radio protectors for medical countermeasures against radiation injuries, and the results obtained from such studies are highly encouraging and fruitful.

    Full Text Available Multifactorial metabolic diseases, for instance diabetes develop several complications like hyperlipidemia, hepatic toxicity, immunodeficiency etc., Hence, instead of mono-drug therapy the management of the disease requires the combination of herbs. Marketed herbal drugs comprise of irrational combinations, which makes their quality control more difficult. Phytoconstituents, despite having excellent bioactivity in vitro demonstrate less or no in vivo actions due to their poor lipid solubility, resulting in high therapeutic dose regimen; phospholipids encapsulation can overcome this problem. Hence, present study was designed to develop a phospholipids encapsulated polyherbal anti-diabetic formulation. In the present study, polyherbal formulation comprises of lyophilized hydro-alcoholic (50% v/v extracts of Momordica charantia, Trigonella foenum-graecum and Withania somnifera 2:2:1, respectively, named HA, optimized based on oral glucose tolerance test model in normal Wistar rats. The optimized formulation (HA entrapped in the phosphatidylcholine and cholesterol (8:2 vesicle system is named HA lipids (HAL. The vesicles were characterized for shape, morphology, entrapment efficiency, polar-dispersity index and release profile in the gastric pH. The antidiabetic potential of HA, marketed polyherbal formulation (D-fit and HAL was compared in streptozotocin-induced diabetic rat model of 21 days study. The parameters evaluated were behavioral changes, body weight, serum glucose level, lipid profile and oxidative stress. The antidiabetic potential of HA (1000 mg/kg was at par with the D-fit (1000 mg/kg. However, the potential was enhanced by phospholipids encapsulation; as HAL (500 mg/kg has shown more significant (P < 0.05 potential in comparison to HA (1000 mg/kg and at par with metformin (500 mg/kg.

    Full Text Available Abstract Background Fenugreek (Trigonella foenum-graecum is a leguminous, annual plant originating in India and North Africa. In recent years Fenugreek has been touted as an ergogenic aid. The purpose of this study was to evaluate the effects of Fenugreek supplementation on strength and body composition. Methods 49 Resistance trained men were matched according to body weight and randomly assigned to ingest in a double blind manner capsules containing 500 mg of a placebo (N = 23, 20 ± 1.9 years, 178 ± 6.3 cm, 85 ± 12.7 kg, 17 ± 5.6 %BF or Fenugreek (N = 26, 21 ± 2.8 years, 178 ± 6 cm, 90 ± 18.2 kg, 19.3 ± 8.4 %BF. Subjects participated in a supervised 4-day per week periodized resistance-training program split into two upper and two lower extremity workouts per week for a total of 8-weeks. At 0, 4, and 8-weeks, subjects underwent hydrodensiometery body composition, 1-RM strength, muscle endurance, and anaerobic capacity testing. Data were analyzed using repeated measures ANOVA and are presented as mean ± SD changes from baseline after 60-days. Results No significant differences (p > 0.05 between groups were noted for training volume. Significant group × time interaction effects were observed among groups in changes in body fat (FEN: -2.3 ± 1.4%BF; PL: -0.39 ± 1.6 %BF, p 0.05. Conclusion It is concluded that 500 mg of this proprietary Fenugreek extraction had a significant impact on both upper- and lower-body strength and body composition in comparison to placebo in a double blind controlled trial. These changes were obtained with no clinical side effects.

    Full Text Available DNA-based testing has been gaining acceptance as a tool for authentication of a wide range of food products; however, its applicability for testing of herbal supplements remains contentious.We utilized Sanger and Next-Generation Sequencing (NGS for taxonomic authentication of fifteen herbal supplements representing three different producers from five medicinal plants: Echinacea purpurea, Valeriana officinalis, Ginkgo biloba, Hypericum perforatum and Trigonella foenum-graecum. Experimental design included three modifications of DNA extraction, two lysate dilutions, Internal Amplification Control, and multiple negative controls to exclude background contamination. Ginkgo supplements were also analyzed using HPLC-MS for the presence of active medicinal components.All supplements yielded DNA from multiple species, rendering Sanger sequencing results for rbcL and ITS2 regions either uninterpretable or non-reproducible between the experimental replicates. Overall, DNA from the manufacturer-listed medicinal plants was successfully detected in seven out of eight dry herb form supplements; however, low or poor DNA recovery due to degradation was observed in most plant extracts (none detected by Sanger; three out of seven-by NGS. NGS also revealed a diverse community of fungi, known to be associated with live plant material and/or the fermentation process used in the production of plant extracts. HPLC-MS testing demonstrated that Ginkgo supplements with degraded DNA contained ten key medicinal components.Quality control of herbal supplements should utilize a synergetic approach targeting both DNA and bioactive components, especially for standardized extracts with degraded DNA. The NGS workflow developed in this study enables reliable detection of plant and fungal DNA and can be utilized by manufacturers for quality assurance of raw plant materials, contamination control during the production process, and the final product.

    Diabetes mellitus is a common effect of uncontrolled high blood sugar and it is associated with long-term damage, dysfunction, and failure of various organs. In the adult population, the global prevalence of diabetes has nearly doubled since 1980. Without effective prevention and management programs, the continuing significant rise in diabetes will have grave consequences on the health and lifespan of the world population, and also on the world economy. Supplements can be used to correct nutritional deficiencies or to maintain an adequate intake of certain nutrients. These are often used as treatments for diabetes, sometimes because they have lower costs, or are more accessible or "natural" compared to prescribed medications. Several vitamins, minerals, botanicals, and secondary metabolites have been reported to elicit beneficial effects in hypoglycemic actions in vivo and in vitro ; however, the data remain conflicting. Many pharmaceuticals commonly used today are structurally derived from natural compounds from traditional medicinal plants. Botanicals that are most frequently used to help manage blood glucose include: bitter melon ( Momordica charantia ), fenugreek ( Trigonella foenum graecum ), gurmar ( Gymnema sylvestre ), ivy gourd ( Coccinia indica ), nopal ( Opuntia spp.), ginseng, Russian tarragon ( Artemisia dracunculus ), cinnamon ( Cinnamomum cassia ), psyllium ( Plantago ovata ), and garlic ( Allium sativum ). In majority of the herbal products and secondary metabolites used in treating diabetes, the mechanisms of action involve regulation of insulin signaling pathways, translocation of GLUT-4 receptor and/or activation the PPARγ. Several flavonoids inhibit glucose absorption by inhibiting intestinal α-amylase and α-glucosidase. In-depth studies to validate the efficacies and safeties of extracts of these traditional medicinal plants are needed, and large, well designed, clinical studies need to be carried out before the use of such preparations can

    Botanical dietary supplements are increasingly popular for women’s health, particularly for older women. The specific botanicals women take vary as a function of age. Younger women will use botanicals for urinary tract infections, especially Vaccinium macrocarpon (cranberry), where there is evidence for efficacy. Botanical dietary supplements for premenstrual syndrome (PMS) are less commonly used, and rigorous clinical trials have not been done. Some examples include Vitex agnus-castus (chasteberry), Angelica sinensis (dong quai), Viburnum opulus/prunifolium (cramp bark and black haw), and Zingiber officinale (ginger). Pregnant women have also used ginger for relief from nausea. Natural galactagogues for lactating women include Trigonella foenum-graecum (fenugreek) and Silybum marianum (milk thistle); however, rigorous safety and efficacy studies are lacking. Older women suffering menopausal symptoms are increasingly likely to use botanicals, especially since the Women’s Health Initiative showed an increased risk for breast cancer associated with traditional hormone therapy. Serotonergic mechanisms similar to antidepressants have been proposed for Actaea/Cimicifuga racemosa (black cohosh) and Valeriana officinalis (valerian). Plant extracts with estrogenic activities for menopausal symptom relief include Glycine max (soy), Trifolium pratense (red clover), Pueraria lobata (kudzu), Humulus lupulus (hops), Glycyrrhiza species (licorice), Rheum rhaponticum (rhubarb), Vitex agnus-castus (chasteberry), Linum usitatissimum (flaxseed), Epimedium species (herba Epimedii, horny goat weed), and Medicago sativa (alfalfa). Some of the estrogenic botanicals have also been shown to have protective effects against osteoporosis. Several of these botanicals could have additional breast cancer preventive effects linked to hormonal, chemical, inflammatory, and/or epigenetic pathways.

    Full Text Available Homeostasis of hematological parameters is essential for assuring a general health status for any living organism. Iron is one of the essential mineral, involved in many vital processes – mainly in blood cells production, but in the same way it can become toxic in very high concentration. Hemoglobin and red blood cells are directed related with the iron ion, due to the high quantity (70% of total iron from organism being part of the blood (hemoglobin and muscle (myoglobin cells. Ferrous ion is part of hemoglobin structure, and red blood cells. But, the administration of high doses of iron can negatively affect the general health status, because the iron alters the enzymatic system in the vital organs. The aim of our experimental study was to verify the hypothesis that in rabbit’s organism, after intraperitoneal administration of 15g Fe2+/body weight as ferrous-gluconate hydro solution, a special diet based on a complex, fresh, organic vegetables (roots and leaves protects the organism by iron intoxication and help the hematological homeostasis. The research experiment was conducted during 43 days in summer time, on German Lop Eared breed young rabbits, which were protected with a diet that consisted of administration of Nigella sativa, some oriental spices (Allium ampeloprasum, Allium tuberosum, Coriandrum sativum, Eruca sativa, Cucumis sativus, Raphanus sativus, Trigonella foenum-graecum and other vegetables (Trifolium, Petroselinum crispum, Dacus carrota subsp.sativus and Cucumis sativus. At the final of experiment we collected blood samples for hematological test and we evaluated the erythrocytes, leukocytes, platelets, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and red cell distribution width. The results were analytical evaluated and only for hemoglobin we obtained significant increase value in experimental rabbits compared to control group of rabbits.

    The purpose of this study is to use a molecular docking approach to identify potential estrogen mimics or anti-estrogens in phytochemicals found in popular dietary herbal supplements. In this study, 568 phytochemicals found in 17 of the most popular herbal supplements sold in the United States were built and docked with two isoforms of the estrogen receptor, ERα and ERβ (a total of 27 different protein crystal structures). The docking results revealed six strongly docking compounds in Echinacea, three from milk thistle (Silybum marianum), three from Gingko biloba, one from Sambucus nigra, none from maca (Lepidium meyenii), five from chaste tree (Vitex agnus-castus), two from fenugreek (Trigonella foenum-graecum), and two from Rhodiola rosea. Notably, of the most popular herbal supplements for women, there were numerous compounds that docked strongly with the estrogen receptor: Licorice (Glycyrrhiza glabra) had a total of 26 compounds strongly docking to the estrogen receptor, 15 with wild yam (Dioscorea villosa), 11 from black cohosh (Actaea racemosa), eight from muira puama (Ptychopetalum olacoides or P. uncinatum), eight from red clover (Trifolium pratense), three from damiana (Turnera aphrodisiaca or T. diffusa), and three from dong quai (Angelica sinensis). Of possible concern were the compounds from men's herbal supplements that exhibited strong docking to the estrogen receptor: Gingko biloba had three compounds, gotu kola (Centella asiatica) had two, muira puama (Ptychopetalum olacoides or P. uncinatum) had eight, and Tribulus terrestris had six compounds. This molecular docking study has revealed that almost all popular herbal supplements contain phytochemical components that may bind to the human estrogen receptor and exhibit selective estrogen receptor modulation. As such, these herbal supplements may cause unwanted side effects related to estrogenic activity.

    Menstrual bleeding cessation is one of the most frequent gynecologic disorders among women in reproductive age. The treatment is based on hormone therapy. Due to the increasing request for alternative medicine remedies in the field of women's diseases, in present study, it was tried to overview medicinal plants used to treat oligomenorrhea and amenorrhea according to the pharmaceutical textbooks of traditional Persian medicine (TPM) and review the evidence in the conventional medicine. This systematic review was designed and performed in 2017 in order to gather information regarding herbal medications of oligomenorrhea and amenorrhea in TPM and conventional medicine. This study had several steps as searching Iranian traditional medicine literature and extracting the emmenagogue plants, classifying the plants, searching the electronic databases, and finding evidences. To search traditional Persian medicine references, Noor digital library was used, which includes several ancient traditional medical references. The classification of plants was done based on the repetition and potency of the plants in the ancient literatures. The required data was gathered using databases such as PubMed, Scopus, Google Scholar, Cochrane Library, Science Direct, and web of knowledge. In present study of all 198 emmenagogue medicinal plants found in TPM, 87 cases were specified to be more effective in treating oligomenorrhea and amenorrhea. In second part of present study, where a search of conventional medicine was performed, 12 studies were found, which had 8 plants investigated: Vitex agnus-castus, Trigonella foenum-graecum, Foeniculum vulgare, Cinnamomum verum, Paeonia lactiflora, Sesamum indicum, Mentha longifolia, and Urtica dioica. Conclusion . Traditional Persian medicine has proposed many different medicinal plants for treatment of oligomenorrhea and amenorrhea. Although just few plants have been proven to be effective for treatment of menstrual irregularities, the results and

  10. Diosgenin, a steroidal saponin, inhibits migration and invasion of human prostate cancer PC-3 cells by reducing matrix metalloproteinases expression.

    Full Text Available BACKGROUND: Diosgenin, a steroidal saponin obtained from fenugreek (Trigonella foenum graecum, was found to exert anti-carcinogenic properties, such as inhibiting proliferation and inducing apoptosis in a variety of tumor cells. However, the effect of diosgenin on cancer metastasis remains unclear. The aim of the study is to examine the effect of diosgenin on migration and invasion in human prostate cancer PC-3 cells. METHODS AND PRINCIPAL FINDINGS: Diosgenin inhibited proliferation of PC-3 cells in a dose-dependent manner. When treated with non-toxic doses of diosgenin, cell migration and invasion were markedly suppressed by in vitro wound healing assay and Boyden chamber invasion assay, respectively. Furthermore, diosgenin reduced the activities of matrix metalloproteinase-2 (MMP-2 and MMP-9 by gelatin zymography assay. The mRNA level of MMP-2, -9, -7 and extracellular inducer of matrix metalloproteinase (EMMPRIN were also suppressed while tissue inhibitor of metalloproteinase-2 (TIMP-2 was increased by diosgenin. In addition, diosgenin abolished the expression of vascular endothelial growth factor (VEGF in PC-3 cells and tube formation of endothelial cells. Our immunoblotting assays indicated that diosgenin potently suppressed the phosphorylation of phosphatidylinositide-3 kinase (PI3K, Akt, extracellular signal regulating kinase (ERK and c-Jun N-terminal kinase (JNK. In addition, diosgenin significantly decreased the nuclear level of nuclear factor kappa B (NF-κB, suggesting that diosgenin inhibited NF-κB activity. CONCLUSION/SIGNIFICANCE: The results suggested that diosgenin inhibited migration and invasion of PC-3 cells by reducing MMPs expression. It also inhibited ERK, JNK and PI3K/Akt signaling pathways as well as NF-κB activity. These findings reveal new therapeutic potential for diosgenin in anti-metastatic therapy.

  11. Vibrational spectroscopy and electrophoresis as a "golden means" in monitoring of polysaccharides in medical plant and gels

    Pielesz, A.

    In recent years, some bioactive polysaccharides isolated from natural sources have attracted much attention in the field of biochemistry and pharmacology. Of them, polysaccharides or their glycoconjugates were shown to exhibit multiple biological activities including anticarcinogenic, anticoagulant, immunostimulating, antioxidant, etc. Pharmacotherapy using plant-derived substances can be currently regarded as a very promising future alternative to conventional therapy. The advanced biotechnologies available today enable chemical investigation of well-defined bioactive plant components as sources of novel drugs. The need for safer drugs without side effects has led to the use of natural ingredients with proven safety. Special interest is focused on plant polysaccharides. This article attempts to review the current structural and conformational characterization of some importantly bioactive monosaccharides isolated from following plant cell-wall: Symphytum officinale (comfrey), Thymus pulegioides (thyme), Trigonella foenum-graecum L. (fenugreek), Tussilago farfara L. (coltsfoot), Hyssopus officinalis (hyssop), Althaea officinalis L. (marshmallow) and Equisetum arvense L. (horsetail). The chemical structures of monosaccharides were analysed using FTIR and Raman spectroscopies as well as cellulose acetate membrane electrophoresis (CAE). The dried plant samples were gently hydrolysed with sulphuric acid. The presence of glucuronic acid, galacturonic acid, alginic acid, glucose, mannose and xylose in the hydrolysates of reference substances and non-defatted plant films was proved. The possibility of a taxonomic classification of plant cell walls based on infrared and Raman spectroscopies and the use of spectral fingerprinting for authentication and detection of adulteration of products rich in cell-wall materials are discussed. Individual bands were selected to monitor the sugar content in medical plant cell walls and to confirm the identity of the analysed plants.

    Silicon (Si) fertilization improves crop cultivation and is commonly added in the form of soluble silicates. However, most natural plant-available Si originates from plant formed amorphous SiO 2 particles, phytoliths, similar to SiO 2 -nanoparticles (SiNP). In this work we, therefore, compared the effect by sodium silicate and that of SiNP on Si accumulation, activity of antioxidative stress enzymes catalase, peroxidase, superoxide dismutase, lignification of xylem cell walls and activity of phenylalanine ammonia-lyase (PAL) as well as expression of genes for the putative silicon transporter (PST), defensive (Tfgd 1) and phosphoenolpyruvate carboxykinase (PEPCK) and protein in fenugreek (Trigonella foenum-graecum L.) grown in hydroponics. The results showed that Si was taken up from both silicate and SiNP treatments and increasing sodium silicate addition increased the translocation of Si to the shoot, while this was not shown with increasing SiNP addition. The silicon transporter PST was upregulated at a greater level when sodium silicate was added compared with SiNP addition. There were no differences in effects between sodium silicate and SiNP treatments on the other parameters measured. Both treatments increased the uptake and accumulation of Si, xylem cell wall lignification, cell wall thickness, PAL activity and protein concentration in seedlings, while there was no effect on antioxidative enzyme activity. Tfgd 1 expression was strongly downregulated in leaves at Si addition. The similarity in effects by silicate and SiNP would be due to that SiNP releases silicate, which may be taken up, shown by a decrease in SiNP particle size with time in the medium.

    DNA-based testing has been gaining acceptance as a tool for authentication of a wide range of food products; however, its applicability for testing of herbal supplements remains contentious. We utilized Sanger and Next-Generation Sequencing (NGS) for taxonomic authentication of fifteen herbal supplements representing three different producers from five medicinal plants: Echinacea purpurea, Valeriana officinalis, Ginkgo biloba, Hypericum perforatum and Trigonella foenum-graecum. Experimental design included three modifications of DNA extraction, two lysate dilutions, Internal Amplification Control, and multiple negative controls to exclude background contamination. Ginkgo supplements were also analyzed using HPLC-MS for the presence of active medicinal components. All supplements yielded DNA from multiple species, rendering Sanger sequencing results for rbcL and ITS2 regions either uninterpretable or non-reproducible between the experimental replicates. Overall, DNA from the manufacturer-listed medicinal plants was successfully detected in seven out of eight dry herb form supplements; however, low or poor DNA recovery due to degradation was observed in most plant extracts (none detected by Sanger; three out of seven-by NGS). NGS also revealed a diverse community of fungi, known to be associated with live plant material and/or the fermentation process used in the production of plant extracts. HPLC-MS testing demonstrated that Ginkgo supplements with degraded DNA contained ten key medicinal components. Quality control of herbal supplements should utilize a synergetic approach targeting both DNA and bioactive components, especially for standardized extracts with degraded DNA. The NGS workflow developed in this study enables reliable detection of plant and fungal DNA and can be utilized by manufacturers for quality assurance of raw plant materials, contamination control during the production process, and the final product. Interpretation of results should involve an

    2017-10-01

    Full Text Available Introduction: Fenugreek (Trigonella foenum- graecum is a medicinal plant extensively distributed in most regions of the world. Fenugreek is an annual plant from the family of papilionaceae, leguminosae. Fenugreek leaves and seeds have been used extensively to prepare extracts and powders for medicinal uses. Its root, leaf and seed contain a number of important medicinal compounds such as polysaccharide, galactomannan, different saponins such as diosgenin, yamogenin, mucilage, volatile oil and alkaloids such as choline and trigonelline. Plant tissue culture is fundamental to most aspects of biotechnology of plants. Establishment of an efficient callus induction and direct regeneration protocol is an essential prerequisite in harnessing the advantage of cell and tissue culture for genetic improvement. For the successful application of the tissue culture technique in plant breeding, callus induction and plant regeneration potential of each plant must be determined. The present study was performed in order to determine the optimum concentration of plant growth regulators (IBA + TDZ for producing of in vitro plantlet using cotyledon and hypocotyl as an explant for two different Iranian genotypes (Ardestani and Neyshabouri. Materials and Methods: In this investigation, Ardestani and Neyshabouri genotypes were used for callus induction and direct shoot regeneration. The medium used in this investigation was MS (Murashige and Skoog basal medium. Then seeds were germinated on MS medium. For callus induction and direct shoot regeneration, cotyledon and hypocotyl explants were excised from 8-day-old sterile seedlings and cultured on MS medium containing various concentrations of IBA and TDZ. In this experiment, two combinations (TDZ + IBA were used. In the first composition, IBA had four levels (0, 0.1, 0.3, 0.5 mg l-1 and TDZ had five levels (0, 0.2, 0.4, 0.6, 0.8 mg l-1 and in the second composition, IBA had four levels (0, 0.05, 0.1, 0.15 mg l-1 and TDZ

    There are several motivations for increasing the diameter of melt textured single domain discs. The maximum magnetic field produced by a trapped field magnet is proportional to the radius of the sample. Furthermore, the availability of trapped field magnets with large diameter could enable their use in applications that have traditionally been considered to require wound electromagnets, such as beam bending magnets for particle accelerators and electric propulsion. We have investigated the possibility of using large area epitaxial growth instead of the conventional point nucleation growth mechanism. This process involves the use of large Y123 seeds for the purpose of increasing the maximum achievable Y123 single domain size. The hot seeding technique using large Y-123 seeds was employed to seed Y-123 samples. Trapped field measurements indicate that single domain samples were indeed grown by this technique. Microstructural evaluation indicates that growth can be characterized by a rapid nucleation followed by the usual peritectic grain growth which occurs when large seeds are used. Critical temperature measurements show that no local T c suppression occurs in the vicinity of the seed. This work supports the suggestion of using an iterative method for increasing the size of Y-123 single domains that can be grown

  1. Oil palm seed distribution

    Durand-Gasselin Tristan

    2005-03-01

    Full Text Available For a tropical plant, the oil palm commodity chain has the peculiarity of possessing a major seed production sector for reasons that are primarily genetic. This seed sector has numerous original aspects. Breeders are also propagators and usually also distribute their seeds. Oil palm seeds are semi-recalcitrant: they display pseudo-dormancy. Achieving seed germination is difficult and requires lengthy treatments and special installations. This restriction greatly influences seed distribution and the role of the different stakeholders in the commodity chain. It was only once it had been discovered how the “sh” gene functioned, which controls shell thickness, and when it became necessary to produce “tenera” seeds derived from exclusively “dura x pisifera” crosses, that a true seed market developed. In addition it is difficult to organize seed distribution to smallholders. This is partly due to difficulties that the profession, or a State-run organization, has in controlling middlemen networks, and partly to the absence of any protective systems (UPOV, plant breeder certificate, etc. that generally oblige breeders to preserve and propagate parents in their own installations. In fact there are major inequalities in the access to seeds between agroindustry and smallholders. Another peculiarity of the oil palm seed market is the virtually total absence of guarantees for buyers: the quality of the research conducted by breeders, the seed production strategies necessary for transferring genetic progress, and the technical quality of production. The only guarantee today comes from the relations of confidence established year after year between breeders/distributors and growers. In this fields, research can lead to some proposals: molecular biology offers some interesting prospects for certifying seed quality and social science develop effective communication methods.

In addition, more or less known folk sayings, proverbs, curses and allegories in which the seed is the key word have been collected. Then, religious books, folk art and literature works (sayings of prominent individuals and experts and observations of the author himself have been studied. According to the collected opus, it can be concluded that the vast importance of seed meaningfully entwined into all spheres of folk life and cultural heritage. Seed is directly tied to the following eight key (revolutionary milestones in the food and economic life of mankind: 1. the first and for the longest time, the seed used to be the main food of the people and the first food reserve; 2.

  8. Seed dormancy and germination.

    Reproduction is a critical time in plant life history. Therefore, genes affecting seed dormancy and germination are among those under strongest selection in natural plant populations. Germination terminates seed dispersal and thus influences the location and timing of plant growth. After seed shedding, germination can be prevented by a property known as seed dormancy. In practise, seeds are rarely either dormant or non-dormant, but seeds whose dormancy-inducing pathways are activated to higher levels will germinate in an ever-narrower range of environments. Thus, measurements of dormancy must always be accompanied by analysis of environmental contexts in which phenotypes or behaviours are described. At its simplest, dormancy can be imposed by the formation of a simple physical barrier around the seed through which gas exchange and the passage of water are prevented. Seeds featuring this so-called 'physical dormancy' often require either scarification or passage through an animal gut (replete with its associated digestive enzymes) to disrupt the barrier and permit germination. In other types of seeds with 'morphological dormancy' the embryo remains under-developed at maturity and a dormant phase exists as the embryo continues its growth post-shedding, eventually breaking through the surrounding tissues. By far, the majority of seeds exhibit 'physiological dormancy' - a quiescence program initiated by either the embryo or the surrounding endosperm tissues. Physiological dormancy uses germination-inhibiting hormones to prevent germination in the absence of the specific environmental triggers that promote germination. During and after germination, early seedling growth is supported by catabolism of stored reserves of protein, oil or starch accumulated during seed maturation. These reserves support cell expansion, chloroplast development and root growth until photoauxotrophic growth can be resumed. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

    Background: extracranial seeding of glioblastoma multiforme (GBM) is very rare and its development depends on several factors. This case report describes two patients suffering from GBM with spinal seeding. In both cases, the anatomic localization of the primary tumor close to the cerebrospinal fluid (CSF) was the main factor for spinal seeding. Case reports: two patients with GBM and spinal seeding are presented. After diagnosis of spinal seeding, both patients were highly symptomatic from their spinal lesions. Case 1 experienced severe pain requiring opiates, and case 2 had paresis of lower limbs as well as urinary retention/incontinence. Both patients were treated with spinal radiation therapy. Nevertheless, they died 3 months after diagnosis of spinal seeding. Results: in both patients the diagnosis of spinal seeding was made at the time of cranial recurrence. Both tumors showed close contact to the CSF initially. Even though the patients underwent intensive treatment, it was not possible to keep them in a symptom-free state. Conclusion: because of short survival periods, patients deserve optimal pain management and dedicated palliative care. (orig.)

    Full Text Available ABSTRACT Physalis peruviana belongs to Solanaceae family and has a high nutritional and nutraceutical potential. The production is intended for fruit consumption and the propagation is mainly by seeds. This study aimed to evaluate the influence of priming on the kinetics of germination of P. peruviana seeds stored at different temperatures. The seeds were stored at 5 and 25 °C in a chamber saturated with zinc chloride solution and in liquid nitrogen (-196 °C. Every 4 months, the seeds were removed from storage for evaluation of germination and moisture content in the laboratory and emergence and development of seedlings in greenhouse. During the last evaluation at 16 months, the seeds under the same conditions were subjected to salt stress. The moisture content varied during the storage period, but was always higher for seeds kept at -196 ºC. These seeds kept high germination percentage in water until 16 months, regardless of the tested temperature; however, in salt solution the germination percentage was significantly reduced.

The Italian and European Communities have the farming capacity to double their production, but international agreements currently prohibit such initiatives. After first providing a panorama of the world oil seed market, this paper discusses new reforms in European Communities internal agricultural policies which currently limit production. These reforms, intended to encourage the production of oil seed for use as an ecological automotive fuel alternative, call for an obligatory set-aside of 15% of producing farm-land in exchange for the compensatory removal of oil seed production limits

    High genetic quality seed is obtained from seed sources that match the planting site, have a good outcrossing rate, and are superior in some desirable characters. Non-degraded natural forests and plantations may be used as untested seed sources, which can sometimes be managed to promote outbreeding...... and increase seed production. Planted seed orchards aim at capturing large genetic variation and are planted in a design that facilitates genetic evaluation and promotes outbred seed production. Good seed production relies upon success of the whole range of reproductive events from flower differentiation...

    Full Text Available Ai Weiwei’s art installation Kui Hua Zi [Sunflower Seeds] took place between 2010 and 2011 in the gigantic Turbine Hall of the Tate Modern Gallery, in London. It consisted of 100 millions hand-crafted porcelain seeds made in Jingdezhen, China.1 An uneven surface to dive into, a haptic space of undulating vision, rustling steps, unusual horizontality, a meaningless quicksand where the separation between artwork and spectator is engulfed, the immunity of distant contemplation denied.

  20. Storage of sunflower seeds

    Denise de Castro Lima

    Full Text Available The sunflower is among the top five crops in the world for the production of edible vegetable oil. The species displays rustic behavior, with an excellent edaphic and climatic adaptability index, being able to be cultivated throughout Brazil. Seed quality is the key to increasing production and productivity in the sunflower. The objective of this work was to monitor the viability of sunflower seeds with a view to their conservation when stored in different environments and packaging. The seeds were packed in paper bags, multilayered paper, black polyethylene and PET bottles; and stored for a period of twelve months in the following environments: dry cold room (10 ºC and 55% RH, the ambient conditions of Fortaleza, Ceará, Brazil (30-32 ºC and 75% RH, refrigerator (4 ºC and 38-43% RH and freezer (-20 ºC. Every three months, the water content of the seeds was determined and germination, accelerated ageing, speed of emergence index, and seedling dry weight were evaluated. The experimental design was completely randomized, in a scheme of split-lots, with four replications. It can be concluded that the natural environment is not suitable for the storage of sunflower seeds. Sunflower seeds remain viable for 12 months when stored in a dry cold room, refrigerator or freezer, irrespective of the type of packaging used.

  1. Seed dispersal in fens

    Middleton, B.; Van Diggelen, R.; Jensen, K.

    2006-01-01

    Question: How does seed dispersal reduce fen isolation and contribute to biodiversity? Location: European and North American fens. Methods: This paper reviews the literature on seed dispersal to fens. Results: Landscape fragmentation may reduce dispersal opportunities thereby isolating fens and reducing genetic exchange. Species in fragmented wetlands may have lower reproductive success, which can lead to biodiversity loss. While fens may have always been relatively isolated from each other, they have become increasingly fragmented in modern times within agricultural and urban landscapes in both Europe and North America. Dispersal by water, animals and wind has been hampered by changes related to development in landscapes surrounding fens. Because the seeds of certain species are long-lived in the seed bank, frequent episodes of dispersal are not always necessary to maintain the biodiversity of fens. However, of particular concern to restoration is that some dominant species, such as the tussock sedge Carex stricta, may not disperse readily between fens. Conclusions: Knowledge of seed dispersal can be used to maintain and restore the biodiversity of fens in fragmented landscapes. Given that development has fragmented landscapes and that this situation is not likely to change, the dispersal of seeds might be enhanced by moving hay or cattle from fens to damaged sites, or by reestablishing lost hydrological connections. ??

    Full Text Available Adequate procedures to evaluate seed vigor are important. Regarding the electrical conductivity test (EC, the interference in the test results caused by seed-borne pathogens has not been clarified. This research was carried out to study the influence of Phomopsis sojae (Leh. and Colletotrichum dematium (Pers. ex Fr. Grove var. truncata (Schw. Arx. fungi on EC results. Soybean seeds (Glycine max L. were inoculated with those fungi using potato, agar and dextrose (PDA medium with manitol (-1.0 MPa and incubated for 20 h at 25 °C. The colony diameter, index of mycelial growth, seed water content, occurrence of seed-borne pathogens, physiological potential of the seeds, measured by germination and vigor tests (seed germination index, cold test, accelerated aging and electrical conductivity, and seedling field emergence were determined. The contents of K+, Ca2+, and Mg2+ in the seed and in the soaking solution were also determined. A complete 2 × 4 factorial design with two seed sizes (5.5 and 6.5 mm and four treatments (control, seeds incubated without fungi, seeds incubated with Phomopsis and seeds incubated with Colletotrichum were used with eight (5.5 mm large seeds and six (6.5 mm large seeds replications. All seeds submitted to PDA medium had their germination reduced in comparison to the control seeds. This reduction was also observed when seed vigor and leached ions were considered. The presence of Phomopsis sojae fungus in soybean seed samples submitted to the EC test may be the cause of misleading results.

    1997-10-01

    Magnetic-seeding filtration consists of two steps: heterogeneous particle flocculation of magnetic and nonmagnetic particles in a stirred tank and high-gradient magnetic filtration (HGMF). The effects of various parameters affecting magnetic-seeding filtration (HGMF). The effects of various parameters affecting magnetic seeding filtration are theoretically and experimentally investigated. A trajectory model that includes hydrodynamic resistance, van der Waals, and electrostatic forces is developed to calculate the flocculation frequency in a turbulent-shear regime. Fractal dimension is introduced to simulate the open structure of aggregates. A magnetic-filtration model that consists of trajectory analysis, a particle build-up model, a breakthrough model, and a bivariate population-balance model is developed to predict the breakthrough curve of magnetic-seeding filtration. A good agreement between modeling results and experimental data is obtained. The results show that the model developed in this study can be used to predict the performance of magnetic-seeding filtration without using empirical coefficients or fitting parameters. 35 refs., 7 figs., 1 tab

    Plant development is well described. However, full understanding of the regulation of processes associated with plant development is still missing. Present Dr.Sc. thesis advances our understanding of the regulation of plant development by quantitative proteomics analyses of seed development of soybean, canola, castor, flax, and model plant arabidopsis in control and environmentally challenged environments. The analysis of greenhouse-grown soybean, canola, castor, and arabidospis provided complex characterization of metabolic processes during seed development, for instance, of carbon assimilation into fatty acids. Furthermore, the analyses of soybean and flax grown in Chernobyl area provided in-depth characterization of seed development in radio-contaminated environment. Soybean and flax were altered by radio-contaminated environment in different way. However, these alterations resulted into modifications in seed oil content. Further analyses showed that soybean and flax possess alterations of carbon metabolism in cytoplasm and plastids along with increased activity of photosynthetic apparatus. Our present experiments are focused on further characterization of molecular bases that might be responsible for alterations of seed oil content in Chernobyl grown plants. (author)

    Problems associated with simplified weed management motivate efforts for diversification. Integrated weed management uses fundamentals of weed biology and applied ecology to provide a framework for diversified weed management programs; the soil seed bank comprises a necessary part of this framework. By targeting seeds, growers can inhibit the propagule pressure on which annual weeds depend for agricultural invasion. Some current management practices affect weed seed banks, such as crop rotation and tillage, but these tools are often used without specific intention to manage weed seeds. Difficulties quantifying the weed seed bank, understanding seed bank phenology, and linking seed banks to emerged weed communities challenge existing soil seed bank management practices. Improved seed bank quantification methods could include DNA profiling of the soil seed bank, mark and recapture, or 3D LIDAR mapping. Successful and sustainable soil seed bank management must constrain functionally diverse and changing weed communities. Harvest weed seed controls represent a step forward, but over-reliance on this singular technique could make it short-lived. Researchers must explore tools inspired by other pest management disciplines, such as gene drives or habitat modification for predatory organisms. Future weed seed bank management will combine multiple complementary practices that enhance diverse agroecosystems. This article is protected by copyright. All rights reserved.

    Magnetic-seeding filtration is a technology under development for the enhanced removal of magnetic and non-magnetic particulates from liquids. This process involves the addition of a small amount of magnetic seed particles (such as naturally occurring iron oxide) to a waste suspension, followed by treatment with a magnetic filter. Non-magnetic and weakly magnetic particles are made to undergo nonhomogeneous flocculation with the seed particles, forming flocs of high magnetic susceptibility that are readily removed by a conventional high-gradient magnetic filter. This technology is applicable to a wide range of liquid wastes, including groundwater, process waters, and tank supernatants. Magnetic-seeding filtration may be used in several aspects of treatment, such as (1) removal of solids, particularly those in the colloidal size range that are difficult to remove by conventional means; (2) removal of contaminants by precipitation processes; and (3) removal of contaminants by sorption processes. Waste stream characteristics for which the technology may be applicable include (1) particle sizes ranging from relatively coarse (several microns) to colloidal particles, (2) high or low radiation levels, (3) broad-ranging flow rates, (4) low to moderate solids concentration, (5) cases requiring high decontamination factors, and (6) aqueous or non-aqueous liquids. At this point, the technology is at the bench-scale stage of development; laboratory studies and fundamental modeling are currently being employed to determine the capabilities of the process.

    In the era of expanding nuclear energy program all over world, the role of radiation biology has acquired greater relevance and significance in addressing the health and environment issues. In view of constant human exposure to background radiation both naturally and man made e.g nuclear power plants and weapons testing, consumer products, medical X-ray, uranium mining and milling etc., the radiobiological research has been devoted to induction of cancer and evaluation of genetic effects. In the present time, nuclear terrorism and weapon related effects are raising much alarm and concern to public health. Obviously, radiation biology research has great potential in diagnosis, therapy and establishing standards for assessment risk from radiation exposure. The development of effective medical countermeasures to protect, mitigate, and treat normal tissue injury needs urgent investigation for basic molecular mechanisms and developing appropriate ready to-use kits using relevant cellular, animal model and clinical trails for practical purposes. Since the use of synthetic compounds is associated with the inherent toxicity, attention in recent years has been directed towards developing radiation countermeasure agents from the natural sources and/or nature-identical molecules. The rich biodiversity available in the Indian subcontinent has yielded several new drugs that find application in the modern medicine and there is a like hood of discovering many more, Over the last few years, interest in evaluating oriental medicinal herbs and edible phyto products for the use in anti-radiation strategies is encouraging and emerging as an acceptable approach for preventing the radiation induced lesions in many countries. Several Indian medicinal plants (Emblica officinalis, Rosemarinus officinalis, Trigonella foenum-graecum, Alstonia scholaris, Tinospora cordifolia, Phyllanthus niruri, Svzvgiumcumini, Aegle marmelos etc) and antioxidant vitamins (C and E) have been tested in this

    Full Text Available Diabetes mellitus is a common effect of uncontrolled high blood sugar and it is associated with long-term damage, dysfunction, and failure of various organs. In the adult population, the global prevalence of diabetes has nearly doubled since 1980. Without effective prevention and management programs, the continuing significant rise in diabetes will have grave consequences on the health and lifespan of the world population, and also on the world economy. Supplements can be used to correct nutritional deficiencies or to maintain an adequate intake of certain nutrients. These are often used as treatments for diabetes, sometimes because they have lower costs, or are more accessible or “natural” compared to prescribed medications. Several vitamins, minerals, botanicals, and secondary metabolites have been reported to elicit beneficial effects in hypoglycemic actions in vivo and in vitro; however, the data remain conflicting. Many pharmaceuticals commonly used today are structurally derived from natural compounds from traditional medicinal plants. Botanicals that are most frequently used to help manage blood glucose include: bitter melon (Momordica charantia, fenugreek (Trigonella foenum graecum, gurmar (Gymnema sylvestre, ivy gourd (Coccinia indica, nopal (Opuntia spp., ginseng, Russian tarragon (Artemisia dracunculus, cinnamon (Cinnamomum cassia, psyllium (Plantago ovata, and garlic (Allium sativum. In majority of the herbal products and secondary metabolites used in treating diabetes, the mechanisms of action involve regulation of insulin signaling pathways, translocation of GLUT-4 receptor and/or activation the PPARγ. Several flavonoids inhibit glucose absorption by inhibiting intestinal α-amylase and α-glucosidase. In-depth studies to validate the efficacies and safeties of extracts of these traditional medicinal plants are needed, and large, well designed, clinical studies need to be carried out before the use of such preparations can be

    The global environmental pollution is responsible for the exposure of living beings to the influence of various technogenic factors, including ionizing radiation. Exposure to such radiation represents a genuine, increasing threat to mankind and our environment. The steadily increasing applications of radiation in clinical practice, industrial and agricultural activities, residual radio-activity resulting from nuclear test explosions, have a measurable impact contributing to significant radiation hazards in humans. Further, the proliferation of terrorism and asymmetric warfare in the 21st century has rendered the modern world a dangerous place to live and work. With the realization of deleterious effects of ionizing radiation, a need was felt to protect human beings against these harmful effects by using physical and/or chemical means. Many chemical compounds have been tested for radio protective action but their practical applicability remained limited owing to their inherent toxicity at the optimum dose level. Various plants have been used for various ailments in humans since time immemorial, and herbal preparations have usually been considered safe and less toxic than the synthetic compounds. Therefore, screening of natural products present a major avenue for the discovery of new radio protective drugs and such products have drawn the attention of investigators during the last two decades. The Indian system of medicine employs a large number of plants and some of these herbals viz. The extracts of certain medicinal plant like Amla (Emblica officinalis), Rosemary (Rosemary officinalis), Methi (Trigonella foenum graecum) sapthaparna (Alstonia scholaris), Bael (Aegle inarmelos), Bhumi amla (Phyllanthus niruri), Jamun (Syzgium cumini), Gloe (Tinospora cordifolia) have been trialed in this laboratory for their radio protective action in various biological systems of mammals. The extracts of various parts of such plants have appreciable DRF on the basis of survival

    Soil to plant transfer via root uptake is one of the major compartments in the radionuclide transfer pathways to man and can be used to assess the internal radiation dose via ingestion. The variability in the Transfer Factor (TF) of Cs isotopes was investigated in three different soils from nuclear power plant sites at Rajasthan and Narora with alkaline sandy loam alluvial and Madras with acidic coastal sandy loam alluvial soil. The soils were characterized for soil properties like texture, pH, EC, organic carbon, CaCO{sub 3} (%), CEC, silt, clay sand etc. and spiked with a mixture of 800 Bq {sup 137}Cs, 300 Bq {sup 134}Cs and 10mg of {sup 133}Cs (stable). Fenugreek (Trigonella foenum-graecum L.) from Leguminosae family an annual plant commonly used as a vegetable was grown in these soils to study the uptake of Cs. The uptake of heavy toxic elements like Pb, Cd, Ni, Cr etc. and nutrients Fe, Co, Cu, Zn, Mn, Ca, Mg, Na and K was also studied. The uptake of heavy toxic elements like Pb, Cd, Ni, Cr etc. and nutrients Fe, Co, Cu, Zn, Mn, Ca, Mg, Na and K was also studied. {sup 137}Cs and{sup 134}Cs was estimated using HPGe detector (15% Relative Efficiency, 54cc-coaxial, 2keV resolution at 1332keV of {sup 60}Co). Stable Cs, K and Na were determined by the Atomic Emission Spectrophotometry and Pb, Cd, Cr etc. by Atomic Absorption Spectrophotometry. Among the three soils the transfer factor for all the elements and Cs was highest for MAPS due to higher organic matter content and acidic pH followed by NAPS and RAPS. The {sup 137}Cs and {sup 134}Cs isotopes have been taken up to the same extent from soil and transfer factors are similar to each other. But the stable Cs uptake appears to be slightly high, probably because of excess of {sup 133}Cs (mg level) added as compared to the radioactive isotopes. In spite of this high difference in the soil concentrations of Cs isotopes, uptake of {sup 133}Cs is not very high indicating to a physiological limiting process for uptake

    The global environmental pollution is responsible for the exposure of living beings to the influence of various technogenic factors, including ionizing radiation. Exposure to such radiation represents a genuine, increasing threat to mankind and our environment. The steadily increasing applications of radiation in clinical practice, industrial and agricultural activities, residual radio-activity resulting from nuclear test explosions, have a measurable impact contributing to significant radiation hazards in humans. Further, the proliferation of terrorism and asymmetric warfare in the 21st century has rendered the modern world a dangerous place to live and work. With the realization of deleterious effects of ionizing radiation, a need was felt to protect human beings against these harmful effects by using physical and/or chemical means. Many chemical compounds have been tested for radio protective action but their practical applicability remained limited owing to their inherent toxicity at the optimum dose level. Various plants have been used for various ailments in humans since time immemorial, and herbal preparations have usually been considered safe and less toxic than the synthetic compounds. Therefore, screening of natural products present a major avenue for the discovery of new radio protective drugs and such products have drawn the attention of investigators during the last two decades. The Indian system of medicine employs a large number of plants and some of these herbals viz. The extracts of certain medicinal plant like Amla (Emblica officinalis), Rosemary (Rosemary officinalis), Methi (Trigonella foenum graecum) sapthaparna (Alstonia scholaris), Bael (Aegle inarmelos), Bhumi amla (Phyllanthus niruri), Jamun (Syzgium cumini), Gloe (Tinospora cordifolia) have been trialed in this laboratory for their radio protective action in various biological systems of mammals. The extracts of various parts of such plants have appreciable DRF on the basis of survival

    In the era of expanding nuclear energy program all over world, the role of radiation biology has acquired greater relevance and significance in addressing the health and environment issues. In view of constant human exposure to background radiation both naturally and man made e.g nuclear power plants and weapons testing, consumer products, medical X-ray, uranium mining and milling etc., the radiobiological research has been devoted to induction of cancer and evaluation of genetic effects. In the present time, nuclear terrorism and weapon related effects are raising much alarm and concern to public health. Obviously, radiation biology research has great potential in diagnosis, therapy and establishing standards for assessment risk from radiation exposure. The development of effective medical countermeasures to protect, mitigate, and treat normal tissue injury needs urgent investigation for basic molecular mechanisms and developing appropriate ready to-use kits using relevant cellular, animal model and clinical trails for practical purposes. Since the use of synthetic compounds is associated with the inherent toxicity, attention in recent years has been directed towards developing radiation countermeasure agents from the natural sources and/or nature-identical molecules. The rich biodiversity available in the Indian subcontinent has yielded several new drugs that find application in the modern medicine and there is a like hood of discovering many more, Over the last few years, interest in evaluating oriental medicinal herbs and edible phyto products for the use in anti-radiation strategies is encouraging and emerging as an acceptable approach for preventing the radiation induced lesions in many countries. Several Indian medicinal plants (Emblica officinalis, Rosemarinus officinalis, Trigonella foenum-graecum, Alstonia scholaris, Tinospora cordifolia, Phyllanthus niruri, Svzvgiumcumini, Aegle marmelos etc) and antioxidant vitamins (C and E) have been tested in this

    Full Text Available Abstract Background A comparative food ethnobotanical study was carried out in fifteen local communities distributed in five districts in the Palestinian Authority, PA (northern West Bank, six of which were located in Nablus, two in Jenin, two in Salfit, three in Qalqilia, and two in Tulkarm. These are among the areas in the PA whose rural inhabitants primarily subsisted on agriculture and therefore still preserve the traditional knowledge on wild edible plants. Methods Data on the use of wild edible plants were collected for one-year period, through informed consent semi-structured interviews with 190 local informants. A semi-quantitative approach was used to document use diversity, and relative importance of each species. Results and discussion The study recorded 100 wild edible plant species, seventy six of which were mentioned by three informants and above and were distributed across 70 genera and 26 families. The most significant species include Majorana syriaca, Foeniculum vulgare, Malvasylvestris, Salvia fruticosa, Cyclamen persicum, Micromeria fruticosa, Arum palaestinum, Trigonella foenum-graecum, Gundelia tournefortii, and Matricaria aurea. All the ten species with the highest mean cultural importance values (mCI, were cited in all five areas. Moreover, most were important in every region. A common cultural background may explain these similarities. One taxon (Majoranasyriaca in particular was found to be among the most quoted species in almost all areas surveyed. CI values, as a measure of traditional botanical knowledge, for edible species in relatively remote and isolated areas (Qalqilia, and Salfit were generally higher than for the same species in other areas. This can be attributed to the fact that local knowledge of wild edible plants and plant gathering are more spread in remote or isolated areas. Conclusion Gathering, processing and consuming wild edible plants are still practiced in all the studied Palestinian areas. About 26

  16. The day of the yam.

    Science.gov (United States)

    Rosser, A

    Yam, the staple food in several tropical countries, is a good source of the steroid used in the manufacture of the pill and other sex hormone preparations -- saponin diosgenin. In the early days of production of oral contraceptives (OCs), most yams were gathered from the wild in Mexico. The type richest in steroids takes 3 years to mature and its cultivation has become something of an art. Yams grow best in light, well-drained soil, and for this reason are grown in mounds which have been heavily manured. Propagation is by planting the tops or heads or by small portions of the tuber which is a swollen shoot. Other varieties are planted before the onset of the rains and the crop harvested about 8 months later. In 1970 the Mexican government nationalized the yam industry as a safeguard. This pushed up prices and the drug companies looked elsewhere for a cheap source. Although Mexico still remains the principal grower, India, South Africa, and the Far East supply the industry with plant origin steroids. As more than 90% of the hefty yam tubers consist of water, well over 100,000 tons have to be harvested every year to provide the 600-700 tons of the saponin diosgenin used by the drug companies. In China, where Western corticosteroids are regarded as too expensive for the barefoot doctors, several species of yam are used. Research has been going on to find another source of diosgenin and the most promising seems to be fenugreek, Trigonella foenumgraecum. "Foenum graecum" is Latin for Greek hay and was used by the early Greeks as a culinary and medicinal herb throughout the Mediterranean area. The richness of fenugreek was used to improve the roundness of women's breasts and to stimulate the flow of milk. Bath University has spent 10 years researching the development of a species of fenugreek which will yield large amounts of diosgenin. A certain amount of steroids come from animal sources. Such steroids are given when there is an adverse reaction from the

    Background: Cancer is a major cause of mortality worldwide with increasing numbers by the years. In North Africa, the number of cancer patients is alarming. Also shocking is that a huge number of cancer patients only have access to traditional medicines due to several factors, e.g., economic difficulties. In fact, medicinal plants are widely used for the treatment of several pathologies, including cancer. Truthfully, herbalists and botanists in North African countries prescribe several plants for cancer treatment. Despite the popularity and the potential of medicinal plants for the treatment of cancer, scientific evidence on their anticancer effects are still scarce for most of the described plants. Objective: Bearing in mind the lack of comprehensive and systematic studies, the aim of this review is to give an overview of studies, namely ethnobotanical surveys and experimental evidence of anticancer effects regarding medicinal plants used in North Africa for cancer therapy. Method: The research was conducted on several popular search engines including PubMed, Science Direct, Scopus and Web of Science. The research focused primarily on English written papers published between the years 2000 and 2016. Results: This review on plants traditionally used by herbalists in North Africa highlights that Morocco and Algeria are the countries with most surveys on the use of medicinal plants in folk medicine. Among the plethora of plants used, Nigella sativa and Trigonella foenum-graecum are the most referred ones by herbalists for the treatment of cancer. Moreover, a plethora of scientific evidence qualifies them as candidates for further drug development. Furthermore, we report on the underlying cellular and molecular mechanisms. Conclusion: Overall, this review highlights the therapeutic potential of some medicinal plants as anticancer agents. The North African flora offers a rich source of medicinal plants for a wide array of diseases, including cancer. The elucidation of

    One of the key problems in production technology of pumpkin seed for oil production is mechanized harvesting and losses of seed during mechanical harvesting. The losses of pumpkin seed during mechanical harvesting at peripheral velocity of 1.57 m/s (optimally adjusted machine) were 4.4% for Gleisdorf species, 5.2% for Slovenska species and 7.8% for pumpkin with husk. The higher average losses of pumpkin seed with husk were caused by tight connection of seed and pumpkin fruit.

    1993-01-01

    Seeds of a set of near-isogenic lines (Brassica napus L.) with different seed coat color from yellow to black were irradiated by 60 Co γ-rays of 150 krad. Seed vigor, superoxide dismutase (SOD) and malondialdehyde (MDA) in germinating seeds were analysed. In these characters, no significant difference between yellow-seeded lines (YLs) and black-seeded lines (BLs) showed before irradiation. But after irradiation, SOD activity in YLs was lower than that in BLs. While MDA content in YLs was obviously higher that that in DLs. As a result of irradiation, seed vigor of YLs was lower than that in BLs. these results indicated that the irradiation resistance of rape seed was related to the level of SOD as well as protective structure or substances in seed coat and that the radiosensitivity of YLs was higher than that of DLs

    Full Text Available ABSTRACT Seed deterioration is a natural and irreversible process. Nevertheless, seed priming with water and antioxidants can minimize oxidative damage in oilseeds, resulting in attenuation of seed deterioration. The objective of this assay was to evaluate seed priming on respiratory activity of Jatropha curcas submitted to accelerated aging. Seeds from two provenances (Janauba and Pedro J. Caballero were submitted to three priming treatments (control, immersion in deionized water, and with 750 µmol L-1 of ascorbic acid and treated for accelerated aging at 41 °C for 72 h. The results showed that the priming of J. curcas seeds promoted tolerance to accelerated aging. Primed seeds, with ascorbic acid from Janauba and deionized water from Pedro J. Caballero, resulted in a higher percentage of normal seedlings, and increased germination speed index and seed respiration. The decline of physiological quality of J. curcas seeds after accelerated aging is directly associated with a reduction in respiratory activity that is related to seed moisture content.

  3. Empty seeds are not always bad: simultaneous effect of seed emptiness and masting on animal seed predation.

    Directory of Open Access Journals (Sweden)

    Ramón Perea

    Full Text Available Seed masting and production of empty seeds have often been considered independently as different strategies to reduce seed predation by animals. Here, we integrate both phenomena within the whole assemblage of seed predators (both pre and post-dispersal and in two contrasting microsites (open vs. sheltered to improve our understanding of the factors controlling seed predation in a wind-dispersed tree (Ulmus laevis. In years with larger crop sizes more avian seed predators were attracted with an increase in the proportion of full seeds predated on the ground. However, for abundant crops, the presence of empty seeds decreased the proportion of full seeds predated. Empty seeds remained for a very long period in the tree, making location of full seeds more difficult for pre-dispersal predators and expanding the overall seed drop period at a very low cost (in dry biomass and allocation of C, N and P. Parthenocarpy (non-fertilized seeds was the main cause of seed emptiness whereas seed abortion was produced in low quantity. These aborted seeds fell prematurely and, thus, could not work as deceptive seeds. A proportion of 50% empty seeds significantly reduced ground seed predation by 26%. However, a high rate of parthenocarpy (beyond 50% empty seeds did not significantly reduce seed predation in comparison to 50% empty seeds. We also found a high variability and unpredictability in the production of empty seeds, both at tree and population level, making predator deception more effective. Open areas were especially important to facilitate seed survival since rodents (the main post-dispersal predators consumed seeds mostly under shrub cover. In elm trees parthenocarpy is a common event that might work as an adaptive strategy to reduce seed predation. Masting per se did not apparently reduce the overall proportion of seeds predated in this wind-dispersed tree, but kept great numbers of seeds unconsumed.

    Five of the global issues most frequently debated today are the decline of biodiversity in general and of agrobiodiversity in particular, climate change, hunger and malnutrition, poverty and water. These issues are connected with each other, and should be dealt with as such. Most of our food comes from seeds (even when we eat meat, we indirectly eat plants, which come from seeds) and food affects our health. The evolution of plant breeding, the science which is responsible for the type and the diversity of seed that farmers plant, and hence for the diversity of food that we eat, helps us understand how agrobiodiversity has decreased. An agro-ecological model of agriculture could be solution to the most important problems affecting the planet, but is often criticized for not being able to produce enough food for a growing population casting doubts on whether food security and food safety can be compatible objectives. Participatory and evolutionary plant breeding, while benefiting from advances in molecular g...

    Sunflower seeds are a rare source of allergy, but several cases of occupational allergies to sunflowers have been described. Sunflower allergens on the whole, however, still await precise and systematic description. We present an interesting case of a 40-year-old male patient, admitted to hospital due to shortness of breath and urticaria, both of which appeared shortly after the patient ingested sunflower seeds. Our laryngological examination revealed swelling of the pharynx with retention of saliva and swelling of the mouth and tongue. During diagnostics, 2 months later, we found that skin prick tests were positive to mugwort pollen (12/9 mm), oranges (6/6 mm), egg protein (3/3 mm), and hazelnuts (3/3 mm). A native prick by prick test with sunflower seeds was strongly positive (8/5 mm). Elevated concentrations of specific IgE against weed mix (inc. lenscale, mugwort, ragweed) allergens (1.04 IU/mL), Artemisia vulgaris (1.36 IU/mL), and Artemisia absinthium (0.49 IU/mL) were found. An ImmunoCap ISAC test found an average level of specific IgE against mugwort pollen allergen component Art v 1 - 5,7 ISU-E, indicating an allergy to mugwort pollen and low to medium levels of specific IgE against lipid transfer proteins (LTP) found in walnuts, peanuts, mugwort pollen, and hazelnuts. Through the ISAC inhibition test we proved that sunflower seed allergen extracts contain proteins cross-reactive with patients’ IgE specific to Art v 1, Art v 3, and Jug r 3. Based on our results and the clinical pattern of the disease we confirmed that the patient is allergic to mugwort pollen and that he had an anaphylactic reaction as a result of ingesting sunflower seeds. We suspected that hypersensitivity to sunflower LTP and defensin-like proteins, both cross-reactive with mugwort pollen allergens, were the main cause of the patient’s anaphylactic reaction.

    This research was aimed at investigating the Effects of Fermented Ginger Rhizome (Zingiber officinale) and Fenu Greek (Trigonella foenum-graceum) on Oxidative stress and Lipid Peroxidation Biomarkers in Poloxamer 407Induced-Hyperlipidemic Wistar Rats. Hyperlipidaemia was induced with poloxamer P407 (1.5 g/kg   b.w. i.p.) The Animals were grouped into six of five animals each group. Group 1 normal control, Group 2 served as the hyperlipidemic control, Group 3 administered 0.26 g/kg cholestyramine, Group 4 fed on Fenugreek 25% supplement. Group 5 fed on 25% fermented ginger supplement, while group 6 were fed on 25% ginger and fenu greek combined   respectively. All treatments were given for a period of four week. Serum antioxidant activities such as catalase (CAT), glutathione peroxidase (GPx), Superoxide dismutase (SOD) and Malondialdehyde were evaluated.  As regards to the catalase activity there was a significant decrease in the groups' fed on 25% fenugreek and 25% fermented ginger supplements respectively. However, co-fed with both supplements significantly increase the catalase activity as compared with the hyperlipidaemic control untreated. Comparism with the positive control cholestyramine, there was also a significant increase. Also in relation to the SOD activity there was a significant increase in the activity as compared with the hyperlipidemic control. Furthermore, the Gpx activity there was a significant increase in the as compared with the hyperlipidemic control. oxidative stress biomarker activities SOD) there was significant increase (p<0.05) when compared with hyperlipidemic control. There was a significant (p<0.05) decrease in the Malondialdehyde levels in the groups fed with the supplement when compared with hyperlipidemic control. In conclusion supplements of Fenugreek and Ginger improved antioxidant status and reduced Malondialdehyde in Poloxamer-407 Induced-Hyperlipidemic Wistar Rats.

    1978-01-01

    In previous experiments, three weeks old cotyledons from gamma irradiated seeds of fenugreek beans were observed to be healthier and heavier than their non-irradiated controls. A hypothesis was set that this phenomenon was due to the accumulation of carbohydrate in the cotyledons. To test this hypothesis an experiment was designed to determine the sugars and starch contents in the cotyledons of an irradiated and nonirradiated groups at different stages of development. At the same time the amylases activities in the same groups were assayed. Results indicated that there was actually increased amount of sugars ad starch in the two and three week old cotyledons of the irradiated as compared to their controls group. These findings support the above hypothesis. The amylase activities were also higher in the irradiated groups as compared to their non-irradiated controls. These results suggest that irradiation induced stimulation of the photosynthetic rate, and amylases' activities, meanwhile, slowed the translocation of carbohydrate nutrients from the cotyledons into the growing seedlings

    Full Text Available Abstract Background The most frequently used tools in bioinformatics are those searching for similarities, or local alignments, between biological sequences. Since the exact dynamic programming algorithm is quadratic, linear-time heuristics such as BLAST are used. Spaced seeds are much more sensitive than the consecutive seed of BLAST and using several seeds represents the current state of the art in approximate search for biological sequences. The most important aspect is computing highly sensitive seeds. Since the problem seems hard, heuristic algorithms are used. The leading software in the common Bernoulli model is the SpEED program. Findings SpEED uses a hill climbing method based on the overlap complexity heuristic. We propose a new algorithm for this heuristic that improves its speed by over one order of magnitude. We use the new implementation to compute improved seeds for several software programs. We compute as well multiple seeds of the same weight as MegaBLAST, that greatly improve its sensitivity. Conclusion Multiple spaced seeds are being successfully used in bioinformatics software programs. Enabling researchers to compute very fast high quality seeds will help expanding the range of their applications.

    Full Text Available The seeding rate influences the intraspecific competition, which might affect the development and quality of seeds in soybean. However, the impact of seeding rate on the physical and physiological qualities of soybean seeds needs to be better elucidated. This study aimed to evaluate the effects of soybean plant density on the seed size as well as the effects of the interaction between the plant density and seed size on the seed mass, green seed occurence, and physiological seed quality. The experiments were carried out in the growing seasons of the years 2013/14 and 2014/15 in a Latossolo Vermelho distroférrico, under a randomized complete block design, using the NK 7059 RR cultivar with six replications. Four plant densities (150, 300, 440, and 560 thousand viable seeds ha–1 were evaluated. After the classification of seeds into four sizes, using a set of sieves, a 4 ×4 factorial scheme was used for the statistical analysis of the four plant densities and four seed sizes. The seed samples were evaluated for the seed mass, green seed percentage, germination, and vigor. Under thermal and water stress during seed development, an increase in the seeding rate led to a reduction in the green seed occurrence and an increase in the seed size and mass. However, in the absence of thermal and water stress, the seed size and mass were not altered by the seeding rate and, there was no occurrence of green seeds.

    1998-01-01

    Full Text Available Seed analysts need to identify seeds, and seed catalogs are used as a reference to accomplish this task. Conventional seed catalogs supply two-dimensional photographs and hand-drawn diagrams. In this study, a new, three-dimensional representation of seeds is developed to supplement these traditional photographs and drawings. QuickTime VR is a promising method for viewing three-dimensional objects on a computer screen. It permits manipulation of an object by rotating and viewing it from any pre-specified angle at an interactive speed, allowing the viewer the sense of examining a hand-held object. In this study, QuickTime VR object movies of seeds were created as interactive "movies" of seeds that can be rotated and scaled to give the viewer the sensation of examining actual seeds. This approach allows the examination of virtual seeds from any angle, permitting more accurate identification of seeds by seed analysts.

    Alberti, W.; Divoux, S.; Pothmann, B.; Tabor, P.; Hermann, K.P.; Harder, D.

    1993-01-01

    To study the interior design of model 6702 and 6711 iodine-125 seeds, contact autoradiographs were performed using mammography film. Improved resolution was obtained using a pin-hole camera with a hole of 0.1 mm x 0.1 mm. With these techniques, qualitative determination of the relative activity distribution within each seed was possible. The number of the activated resin spheres and the positions of the centers of these spheres can be exactly determined. A model calculation shows that variations in the arrangement of the activated spheres within a seed have a moderate influence on the dose distribution at source distances below 10 mm. Knowing the exact source configuration may be useful when comparing dose calculations with measured data for model 6702 125 I seeds which are currently employed in ophthalmic plaque and implant therapy of other tumors. 16 refs., 5 figs., 2 tabs

    1969-07-01

    Ethylene activity in lettuce seed (Lactuca satina) germination and tomato (Lycopersicon esculentum) petiole epinasty has been characterized by using heat to inhibit ethylene synthesis. This procedure enabled a separation of the production of ethylene from the effect of ethylene. Ethylene was required in tomato petioles to produce the epinastic response and auxin was found to be active in producing epinasty through a stimulation of ethylene synthesis with the resulting ethylene being responsible for the epinasty. In the same manner, it was shown that gibberellic acid stimulated ethylene synthesis in lettuce seeds. The ethylene produced then in turn stimulated the seeds to germinate. It was hypothesized that ethylene was the intermediate which caused epinasty or seed germination. Auxin and gibberellin primarily induced their response by stimulating ethylene production.

    Full Text Available This study was conducted to determine the effects of neem (Azadirachta indica A. Juss and moringa (Moringa oleifera seed oils on the storability of cowpea grain. Cowpea samples were treated with various concentrations (0.5, 1.0, and 1.5 mL/200 g cowpea of pure neem and moringa oils and their mixtures in ratios of 1:1, 1:2, and 1:3. The treated cowpea samples were stored for 180 days. Data were collected every 30 days on number of eggs laid, total weevil population, and percentage of uninfested grains and analysed statistically. Significantly different means were compared using LSD at <.05. Increasing oil concentration resulted in better cowpea protection, for example, in oviposition where the control had 6513 eggs, only 8 eggs were recorded in pure neem oil-treated sample at 0.5 mL/200 g. Generally, better results were obtained with higher oil concentrations either in their pure forms or mixtures. The control had a total weevil population of 4988, while most treated samples had none. The control samples had 0% uninfested grains, while 73–94% of uninfested grains were observed in treated samples after 6 months of storage. Therefore, mixture of the oils at 1.5 mL/200 g can be effectively used to store cowpea.

    Full Text Available Timely harvest is critical to achieve maximum seed viability and vigour in agricultural production. However, little information exists concerning how to reap the best quality seeds of Leymus chinensis, which is the dominant and most promising grass species in the Songnen Grassland of Northern China. The objective of this study was to investigate and evaluate possible quality indices of the seeds at different days after peak anthesis. Seed quality at different development stages was assessed by the colours of the seed and lemmas, seed weight, moisture content, electrical conductivity of seed leachate and germination indices. Two consecutive years of experimental results showed that the maximum seed quality was recorded at 39 days after peak anthesis. At this date, the colours of the seed and lemmas reached heavy brown and yellow, respectively. The seed weight was highest and the moisture content and the electrical conductivity of seed leachate were lowest. In addition, the seed also reached its maximum germination percentage and energy at this stage, determined using a standard germination test (SGT and accelerated ageing test (AAT. Thus, Leymus chinensis can be harvested at 39 days after peak anthesis based on the changes in parameters. Colour identification can be used as an additional indicator to provide a more rapid and reliable measure of optimum seed maturity; approximately 10 days after the colour of the lemmas reached yellow and the colour of the seed reached heavy brown, the seed of this species was suitable for harvest.

    2010-10-27

    Hardseededness in annual wild soybean (Glycine soja Sieb. Et Zucc.) is a valuable trait that affects the germination, viability, and quality of stored seeds. Two G. soja ecotypes native to Shandong Province of China have been used to identify the phenolics in the seed coat that correlate with the seed hardness and seed germination. Three major phenolics from the seed coat were isolated and identified as epicatechin, cyanidin 3-O-glucoside, and delphinidin 3-O-glucoside. Of the three phenolics, only the change of epicatechin exhibited a significant positive correlation with the change of hard seed percentages both under different water conditions during seed development and under different gas conditions during seed storage. Epicatechin also reveals a hormesis-like effect on the seed germination of G. soja. Epicatechin is suggested to be functionally related to coat-imposed hardseededness in G. soja.

    Full Text Available The Seed Proteome Web Portal (SPWP; http://www.seedproteome.com/ gives access to information both on quantitative seed proteomic data and on seed-related protocols. Firstly, the SPWP provides access to the 475 different Arabidopsis seed proteins annotated from 2 dimensional electrophoresis (2DE maps. Quantitative data are available for each protein according to their accumulation profile during the germination process. These proteins can be retrieved either in list format or directly on scanned 2DE maps. These proteomic data reveal that 40% of seed proteins maintain a stable abundance over germination, up to radicle protrusion. During sensu stricto germination (24 h upon imbibition about 50% of the proteins display quantitative variations, exhibiting an increased abundance (35% or a decreasing abundance (15%. Moreover, during radicle protrusion (24 h to 48 h upon imbibition, 41% proteins display quantitative variations with an increased (23% or a decreasing abundance (18%. In addition, an analysis of the seed proteome revealed the importance of protein post-translational modifications as demonstrated by the poor correlation (r2 = 0.29 between the theoretical (predicted from Arabidopsis genome and the observed protein isoelectric points. Secondly, the SPWP is a relevant technical resource for protocols specifically dedicated to Arabidopsis seed proteome studies. Concerning 2D electrophoresis, the user can find efficient procedures for sample preparation, electrophoresis coupled with gel analysis and protein identification by mass spectrometry, which we have routinely used during the last 12 years. Particular applications such as the detection of oxidized proteins or de novo synthetized proteins radiolabeled by [35S]-methionine are also given in great details. Future developments of this portal will include proteomic data from studies such as dormancy release and protein turnover through de novo protein synthesis analyses during germination.

    Transperineal I-125 seed brachytherapy for prostate cancer is rapidly expanding in Japan. Seed migrations to lung and abdomen are well known complication in the seed brachytherapy. The rate of incidence and the predisposing factors were studied. From April 2004 through January 2005, 36 patients underwent transperineal I-125 seed brachytherapy for prostate cancer. In all patients loose I-125 seeds were inserted with Mick applicator according to modified peripheral loading pattern. One day, 1 week, and 1 month after the procedure, posteroanterior and lateral chest X-rays and abdominal X-ray were performed. Abdominal and chest seed migrations were seen in 11 (30.6%) and 14 (38.9%) patients, respectively. In total, 20 patients (55.6%) showed seed migrations. Forty-two I-125 seeds migrated out of 2,508 implanted seeds. Most of the migrations were seen until 1 month after the procedure. The preplanned number of the extraprostatic seeds had a statistically significant influence upon the incidence of seed migration. Seed migration is not a rare phenomenon in transperineal I-125 seed brachytherapy for prostate cancer. To confirm seed migration, X-ray examinations 1 month after the procedure are suited.

    Full Text Available This study investigated the nutrient composition of D. edulis seed and seed coat mixture. Qualitative and quantitative phytochemicals, proximate, and vitamin compositions were evaluated using standard methods. Saponins were very high, alkaloids, flavonoids, and tannins were high, while terpenoids were low, and glycosides, aldehydes, and steroids were absent. The quantitative phytochemical determination followed the order; saponin > kaempferol > rutin > catechin > tannin > sapogenin > lunamarine > phenol > ribalinidine > anthocyanin > oxalate > phytate. For the proximate composition, carbohydrates had the highest concentration, followed by lipids and fibre, while, protein concentration was the lowest. Vitamin E (5.42 mg/100g, vitamin C (3.24 mg/100g, and vitamin A (2.84 mg/100g were the highest occurring constituent vitamins while vitamin B12 (0.035 mg/100g and vitamin B2 (0.075 mg/100g were the least occurring vitamins. This study has shown the rich phytochemical composition of D. edulis seed and seed coat mixture while showing deficiencies in proteins, distinct vitamins, and ash contents.

    This chapter pertains to the techniques of capturing the best genetic quality seeds a seed source can produce at the optimal time of high physiological maturity and maintaining these qualities throughout the handling processes, all at a minimum cost. Different collection and processing techniques...... apply to different species, seed types, situations, and purposes. Yet the collection and processing toolbox contains a number of “standard” methods for most of these groups. Records and documentation help in evaluating “best practice” for future method improvement, and it helps in linking offspring...... to seed source. Conditions are set for short- and long-term seed storage by their inert storability physiology. The potential storage life of seed may for some robust “orthodox” species be several decades, while no available storage conditions can maintain viability for sensitive “recalcitrant” seed. Seed...

    2004-01-01

    An unusual seed mutant in watermelon (Citrullus lanatus var. lanatus) has seeds with a fleshy pericarp, commonly called egusi seeds. The origin of the phenotype is unknown, but it is widely cultivated in Nigeria for the high protein and carbohydrate content of the edible seeds. Egusi seeds have a thick, fleshy pericarp that appears during the second to third week of fruit development. We studied the inheritance of this phenotype in crosses of normal seeded Charleston Gray and Calhoun Gray with two plant introduction accessions, PI 490383w and PI 560006, having the egusi seed type. We found that the egusi seed type is controlled by a single recessive gene, and the symbol eg was assigned. Copyright 2004 The American Genetic Association

    1998-01-01

    Full Text Available Seed quality will remain the centerpiece of successful agricultural programs in the year 2000. As new changes occur in agriculture driven by advancements in biotechnology, seed enhancement technologies, a more diverse seed user clientele, and communication technologies, successful seed companies will require a knowledgeable and informed workforce to assure high seed quality. A new approach to seed technology training is professed that relies on the establishment of a three-institution consortium to achieve this objective. Advantages of the consortium are identified that emphasize the unique strengths of each institution, their geographic advantages representing major climactic/agricultural zones in the world, and differing approaches to seed technology training that are facilitated by increasing ease of global communication. This may be a better way to conduct seed technology training in the year 2000.

    2016-01-01

    Full Text Available Morphological variation in seed characters includes differences in seed size and shape. Seed shape is an important trait in plant identification and classification. In addition it has agronomic importance because it reflects genetic, physiological, and ecological components and affects yield, quality, and market price. The use of digital technologies, together with development of quantification and modeling methods, allows a better description of seed shape. Image processing systems are used in the automatic determination of seed size and shape, becoming a basic tool in the study of diversity. Seed shape is determined by a variety of indexes (circularity, roundness, and J index. The comparison of the seed images to a geometrical figure (circle, cardioid, ellipse, ellipsoid, etc. provides a precise quantification of shape. The methods of shape quantification based on these models are useful for an accurate description allowing to compare between genotypes or along developmental phases as well as to establish the level of variation in different sets of seeds.

  1. The biomechanics of seed germination.

    Science.gov (United States)

    Steinbrecher, Tina; Leubner-Metzger, Gerhard

    2017-02-01

    From a biomechanical perspective, the completion of seed (and fruit) germination depends on the balance of two opposing forces: the growth potential of the embryonic axis (radicle-hypocotyl growth zone) and the restraint of the seed-covering layers (endosperm, testa, and pericarp). The diverse seed tissues are composite materials which differ in their dynamic properties based on their distinct cell wall composition and water uptake capacities. The biomechanics of embryo cell growth during seed germination depend on irreversible cell wall loosening followed by water uptake due to the decreasing turgor, and this leads to embryo elongation and eventually radicle emergence. Endosperm weakening as a prerequisite for radicle emergence is a widespread phenomenon among angiosperms. Research into the biochemistry and biomechanics of endosperm weakening has demonstrated that the reduction in puncture force of a seed's micropylar endosperm is environmentally and hormonally regulated and involves tissue-specific expression of cell wall remodelling proteins such as expansins, diverse hydrolases, and the production of directly acting apoplastic reactive oxygen. The endosperm-weakening biomechanics and its underlying cell wall biochemistry differ between the micropylar (ME) and chalazal (CE) endosperm domains. In the ME, they involve cell wall loosening, cell separation, and programmed cell death to provide decreased and localized ME tissue resistance, autolysis, and finally the formation of an ME hole required for radicle emergence. Future work will further unravel the molecular mechanisms, environmental regulation, and evolution of the diverse biomechanical cell wall changes underpinning the control of germination by endosperm weakening. © The Author 2016.

    So far there exists no corresponding quality test procedures and grading standards for the seed of Prunus humilis, which is one of the important source of base of semen pruni. Therefor we set up test procedures that are adapt to characteristics of the P. humilis seed through the study of the test of sampling, seed purity, thousand-grain weight, seed moisture, seed viability and germination percentage. 50 cases of seed specimens of P. humilis tested. The related data were analyzed by cluster analysis. Through this research, the seed quality test procedure was developed, and the seed quality grading standard was formulated. The seed quality of each grade should meet the following requirements: for first grade seeds, germination percentage ≥ 68%, thousand-grain weight 383 g, purity ≥ 93%, seed moisture ≤ 5%; for second grade seeds, germination percentage ≥ 26%, thousand-grain weight ≥ 266 g, purity ≥ 73%, seed moisture ≤9%; for third grade seeds, germination percentage ≥ 10%, purity ≥ 50%, thousand-grain weight ≥ 08 g, seed moisture ≤ 13%.

    Bas, J. M.; Oliveras, J.; Gómez, C.

    2009-05-01

    Benefits conferred on plants in ant-mediated seed dispersal mutualisms (myrmecochory) depend on the fate of transported seeds. We studied the effects of elaiosome presence, seed size and seed treatment (with and without passage through a bird's digestive tract) on short-term seed fate in Rhamnus alaternus. In our study, we define short-term seed, or initial, seed fate, as the location where ants release the seeds after ant contact with it. The elaiosomes had the most influence on short-term fate, i.e. whether or not seeds were transported to the nest. The workers usually transported big seeds more often than small ones, but small ants did not transport large seeds. Effect of seed size on transport depended on the ant species and on the treatment of the seed (manual extraction simulating a direct fall from the parent plant vs. bird deposition corresponding to preliminary primary dispersal). Probability of removal of elaiosome-bearing seeds to the nest by Aphaenogaster senilis increased with increasing seed weight.

  10. Stimulation of lettuce seed germination by ethylene.

    Science.gov (United States)

    Abeles, F B; Lonski, J

    1969-02-01

    Ethylene increased the germination of freshly imbibed lettuce (Lactuca sativa L. var. Grand Rapids) seeds. Seeds receiving either red or far-red light or darkness all showed a positive response to the gas. However, ethylene was apparently without effect on dormant seeds, those which failed to germinate after an initial red or far-red treatment. Carbon dioxide, which often acts as a competitive inhibitor of ethylene, failed to clearly reverse ethylene-enhanced seed germination. While light doubled ethylene production from the lettuce seeds, its effect was not mediated by the phytochrome system since both red and far-red light had a similar effect.

The best temperature for germination under constant light was 30oC. The imbibition of T. impetiginosa seeds followed the common triphasic pattern, with most of the seeds attaining phase II at 24 hours and phase III at 72 hours of imbibition. Visible germination, as radicle elongation, started at 30 hours in water-imbibed seeds and at 24 hours in GA-imbibed seeds. Seeds imbibed in Paclobutrazol, an inhibitor of GA biosynthesis, failed to germinate. However, application of exogenous gibberellins overcame inhibition and allowed germination, suggesting that GAs are regulators of Tabebuia impetiginosa seed germination. The results suggested that germination in Tabebuia impetiginosa seeds is controlled by elongation of the radicle and gibberellins may play an important role in regulating it. The possible role of gibberellins is discussed.

    In order to optimize the testing methods for Paeonia suffruticosa seed quality, and provide basis for establishing seed testing rules and seed quality standard of P. suffruticosa. The seed quality of P. suffruticosa from different producing areas was measured based on the related seed testing regulations. The seed testing methods for quality items of P. suffruticosa was established preliminarily. The samples weight of P. suffruticosa was at least 7 000 g for purity analysis and was at least 700 g for test. The phenotypic observation and size measurement were used for authenticity testing. The 1 000-seed weight was determined by 100-seed method, and the water content was carried out by low temperature drying method (10 hours). After soaking in distilled water for 24 h, the seeds was treated with different temperature stratifications of day and night (25 degrees C/20 degrees C, day/night) in the dark for 60 d. After soaking in the liquor of GA3 300 mg x L(-1) for 24 h, the P. suffruticos seeds were cultured in wet sand at 15 degrees C for 12-60 days for germination testing. Seed viability was tested by TlC method.

    Parasitic Orobanchaceae germinate only after receiving a chemical stimulus from roots of potential host plants. A preparatory phase of several days that follows seed imbibition, termed conditioning, is known to be required; thereafter the seeds can respond to germination stimulants. The aim of this study was to examine whether conditioning is essential for stimulant receptivity. Non-conditioned seeds of both Orobanche cumana Wallr. and O. aegyptiaca Pers. [syn. Phelipanche aegyptiaca (Pers.) Pomel] were able to germinate in response to chemical stimulation by GR24 even without prior conditioning. Stimulated seeds reached maximal germination rates about 2 weeks after the onset of imbibition, no matter whether the seeds had or had not been conditioned before stimulation. Whereas the lag time between stimulation and germination response of non-conditioned seeds was longer than for conditioned seeds, the total time between imbibition and germination was shorter for the non-conditioned seeds. Unlike the above two species, O. crenata Forsk. was found to require conditioning prior to stimulation. Seeds of O. cumana and O. aegyptiaca are already receptive before conditioning. Thus, conditioning is not involved in stimulant receptivity. A hypothesis is put forward, suggesting that conditioning includes (a) a parasite-specific early phase that allows the imbibed seeds to overcome the stress caused by failing to receive an immediate germination stimulus, and (b) a non-specific later phase that is identical to the pregermination phase between seed imbibition and actual germination that is typical for all higher plants.

    Full Text Available The development of automated systems has been highlighted in the most diverse productive sectors, among them, the agricultural sector. These systems aim to optimize activities by increasing operational efficiency and quality of work. In this sense, the present work has the objective of evaluating a prototype developed for seed count in laboratory, using Arduino microcontroller. The prototype of the system for seed counting was built using a dosing mechanism commonly used in seeders, electric motor, Arduino Uno, light dependent resistor and light emitting diode. To test the prototype, a completely randomized design (CRD was used in a two-factorial scheme composed of three groups defined according to the number of seeds (500, 1000 and 1500 seeds tested, three speeds of the dosing disc that allowed the distribution in 17, 21 and 32 seeds per second, with 40 repetitions evaluating the seed counting prototype performance in different speeds. The prototype of the bench counter showed a moderate variability of seed number of counted within the nine tests and a high precision in the seed count on the distribution speeds of 17 and 21 seeds per second (s-1 up to 1500 seeds tested. Therefore, based on the observed results, the developed prototype presents itself as an excellent tool for counting seeds in laboratory.

    Waterbirds disperse a wide range of plant seeds via their guts, promoting biotic connectivity between isolated habitat patches. However, the intensity of digestive forces encountered by seeds, and therefore their potential to survive digestive tract passage, varies within and between waterbird species. Here, we investigate under controlled conditions how the interaction between seed traits and digestive strategies affect the germinability of seeds following waterbird-mediated dispersal. We exposed seeds of 30 wetland plant species to the main digestive processes in the dabbling duck digestive system: mechanical, chemical and intestinal digestion. These were simulated by 1) a pressure test and scarification treatment, 2) incubation in simulated gastric juice, and 3) incubation in intestinal contents of culled mallards (Anas platyrhynchos). We evaluated their separate and combined effects on seed germination, and identified the role of seed size and seed coat traits in resisting the digestive forces. Seeds were generally resistant to separate digestive processes, but highly sensitive to a combination. Resistance to mechanical break-down was reduced by up to 80% by chemical pre-treatment, especially for seeds with permeable coats. Scarified seeds were 12-17% more vulnerable to chemical and intestinal digestive processes than undamaged seeds. Large seeds and seeds with thin, permeable coats were particularly sensitive to chemical and intestinal digestion. These results indicate that efficient digestion of seeds requires multiple digestive processes. The gizzard, responsible for mechanical digestion, plays a key role in seed survival. Omnivorous birds, which have relatively light gizzards compared to pure herbivores or granivores, are thus most likely to disperse seeds successfully. Regardless of digestive strategy, small seeds with tough seed coats are most resistant to digestion and may be adapted to endozoochorous dispersal by waterbirds.

    Full Text Available The objective of this study was to study the seed quality aspects of wheat (Triticum aestivum L. and the extent of weed seed contamination present in wheat seeds produced in different regions of Iran. Four districts (cities, each including 12 fields (six certified seed fields and six farm-saved seed fields, were selected in each regions (provinces. One kilogram of the wheat seed sample was collected from each field for analysis in the laboratory. Wheat seeding was commonly done by farm-saved seed sourced from within the farm due to the high costs of certified seeds purchased from outside sources, followed by the low seed quality. The use of a farm-saved seed resulted in a higher germination rate and a lower mean time to germination compared with another system. The more positive temperatures experienced by mother plants could decrease the number of normal seedling and seedling length vigor index. Generally there was virtually no difference about physiological quality between certified seed and farm-saved seed sector that is related to lower quality of certified seed. The certified produced seeds had the lower number of weed seed, species and genus before and after cleaning. The highest seed purity and 1000 seed weight was obtained from the certified seed production system. The need for cleaning the farm-saved seed samples before sowing is one of the important findings of this survey.

    production on three seed quality components: seed mass, germination and seed vigour. In response to elevated CO2, seed mass has been reported to both increase and decrease in C3 plants, but not change in C4 plants. Increases are greater in legumes than non-legumes, and there is considerable variation among...... species. Seed mass increases may result in a decrease of seed nitrogen (N) concentration in non-legumes. Increasing temperature may decrease seed mass because of an accelerated growth rate and reduced seed filling duration, but lower seed mass does not necessarily reduce seed germination or vigour.

    The so-called 'vault of the end of the world', located in the archipelago Arctic Svalbard, brings together more than 860,000 samples seeds from around the world. The purpose of your existence -like the of thousands of other banks of its kind in all the planet - is to preserve the genetic diversity of crops, most of them are now disappearing. An international treaty approved by the United Nations, and in force since 2004, allowed the construction of this 'Sanctuary' where more than one hundred countries maintain their own banks of seeds, freezing them to 18 degrees below zero to lower its biological activity.

    Plant organs, such as seeds, are primary sources of food for both humans and animals. Seed size is one of the major agronomic traits that have been selected in crop plants during their domestication. Legume seeds are a major source of dietary proteins and oils. Here, we report a conserved role for the BIG SEEDS1 (BS1) gene in the control of seed size and weight in the model legume Medicago truncatula and the grain legume soybean (Glycine max). BS1 encodes a plant-specific transcription regulator and plays a key role in the control of the size of plant organs, including seeds, seed pods, and leaves, through a regulatory module that targets primary cell proliferation. Importantly, down-regulation of BS1 orthologs in soybean by an artificial microRNA significantly increased soybean seed size, weight, and amino acid content. Our results provide a strategy for the increase in yield and seed quality in legumes.

    2011-01-01

    Full Text Available The funicular cover of the Opuntia tomentosa seed limits imbibition; germination occurs only when the funicle is weakened or the funicular valve is removed. We investigated the role of fungi in funicular weakening and seed germination. Seeds that had been either buried in one of two sites or stored in the laboratory were germinated with and without a valve. Disinfected or nondisinfected seeds and their naked embryos were cultivated on agar or PDA. None of the 11 identified fungal genera grew on the disinfected control seeds or the embryos. The mycoflora present on disinfected and nondisinfected exhumed seeds suggest that the fungal colonization occurred in the soil and differed between the burial sites. Exhumed seeds with and without a valve germinated in high percentages, whereas only the control seeds without a valve germinated. Scanning electron micrographs showed that the hyphae penetrated, cracked, and eroded the funicular envelope of exhumed seeds.

    Full Text Available Most of the medicinal plants have seed dormancy or poor seed germination. This is due to their natural compounds or their morphological structure. Existence of such mechanisms makes the seeds able to endure harsh environments, stressful conditions or natural ageing. Different seed enhancement treatments were proposed in order to improve seed germination. In this study, it was examined Silybum marianum seed longevity (0, 48 and 72 hour of ageing and the response to seed priming when using different concentrations of cytokinin (50, 200, 350 and 500 ppm and different duration of treatment (8, 12 and 24 hour. Results revealed that ageing could be successfully alleviated using seed priming. Seed ageing significantly affected seed germination and vigour. Application of cytokinin considerably improved seed vigour in aged and non aged seeds. The most effective seed priming treatment was with 500 ppm cytokine, with the duration of 24 hours. In conclusion, it can be recommend the used of plant growth regulators like cytokine, as a good priming agent, to recover losses of seed quality and improve germination characteristics.

    Full Text Available Seed is a condensed form of plant. Under suitable environmental conditions, it can resume the metabolic activity from physiological quiescent status, and mobilize the reserves, biosynthesize new proteins, regenerate organelles and cell membrane, eventually protrude the radicle and enter into seedling establishment. So far, how these activities are regulated in a coordinated and sequential manner is largely unknown. With the availability of more and more genome sequence information and the development of mass spectrometry (MS technology, proteomics has been widely applied in analyzing the mechanisms of different biological processes, and proved to be very powerful. Regulation of rice seed germination is critical for rice cultivation. In recent years, a lot of proteomic studies have been conducted in exploring the gene expression regulation, reserves mobilization and metabolisms reactivation, which brings us new insights on the mechanisms of metabolism regulation during this process. Nevertheless, it also invokes a lot of questions. In this mini-review, we summarized the progress in the proteomic studies of rice seed germination. The current challenges and future perspectives were also discussed, which might be helpful for the following studies.

    Seed production requires the transfer of nutrients from the maternal seed coat to the filial endosperm and embryo. Because seed coat and filial tissues are symplasmically isolated, nutrients arriving in the seed coat via the phloem must be exported to the apoplast before reaching the embryo. Proteins implicated in the transfer of inorganic phosphate (Pi) from the seed coat to the embryo are unknown despite seed P content being an important agronomic trait. Here we show that the Arabidopsis Pi exporters PHO1 and PHOH1 are expressed in the chalazal seed coat (CZSC) of developing seeds. PHO1 is additionally expressed in developing ovules. Phosphorus (P) content and Pi flux between the seed coat and embryo were analyzed in seeds from grafts between WT roots and scions from either pho1, phoh1, or the pho1 phoh1 double mutant. Whereas P content and distribution between the seed coat and embryo in fully mature dry seeds of these mutants are similar to the WT, at the mature green stage of seed development the seed coat of the pho1 and pho1 phoh1 mutants, but not of the phoh1 mutant, retains approximately 2-fold more P than its WT control. Expression of PHO1 under a CZSC-specific promoter complemented the seed P distribution phenotype of the pho1 phoh1 double mutant. CZSC-specific down-expression of PHO1 also recapitulated the seed P distribution phenotype of pho1. Together, these experiments show that PHO1 expression in the CZSC is important for the transfer of P from the seed coat to the embryo in developing seeds. Copyright © 2017 Elsevier Ltd.

    In prostate brachytherapy, seeds can detach from their deposited sites and move locally in the pelvis or migrate to distant sites including the pulmonary and cardiac regions. Undesirable consequences of seed migration include inadequate dose coverage of the prostate and tissue irradiation effects at the site of migration. Thus, it is clinically important to develop seed immobilization techniques. We first analyze the possible causes for seed movement, and propose three potential techniques for seed immobilization: (1) surgical glue, (2) laser coagulation and (3) diathermy coagulation. The feasibility of each method is explored. Experiments were carried out using fresh bovine livers to investigate the efficacy of seed immobilization using surgical glue. Results have shown that the surgical glue can effectively immobilize the seeds. Evaluation of the radiation dose distribution revealed that the non-immobilized seed movement would change the planned isodose distribution considerably; while by using surgical glue method to immobilize the seeds, the changes were negligible. Prostate brachytherapy seed immobilization is necessary and three alternative mechanisms are promising for addressing this issue. Experiments for exploring the efficacy of the other two proposed methods are ongoing. Devices compatible with the brachytherapy procedure will be designed in future. (orig.)

    Three categories of seed storage behavior are generally recognized among plant species: orthodox, intermediate and recalcitrant. Intermediate seeds cannot be stored in liquid nitrogen (LN) without a previous partial dehydration process. The water content (WC) of the seeds at the moment of immersion in LN must be regarded as the most critical factor in cryopreservation. The purpose of this study was to investigate the basis of the optimal hydration status for cryopreservation of Citrus seeds: C. sinensis (sweet orange), C. paradisi (grapefruit), C. reticulata (mandarin) in LN. To study the tolerance to dehydration and LN exposure, seeds were desiccated by equilibration at relative humidities between 11 and 95%. Sorption isotherms were determined and modeled; lipid content of the seeds was measured. Seed desiccation sensitivity was quantified by the quantal response model. Differential scanning calorimetry (DSC) thermograms were determined on cotyledon tissue at different moisture contents to measure ice melting enthalpies and unfrozen WC. Samples of total seed lipid extract were also analyzed by DSC to identify lipid transitions in the thermograms. The limit of hydration for LN Citrus seeds treatment corresponded to the unfrozen WC in the tissue, confirming that seed survival strictly depended on avoidance of intracellular ice formation.

    Leon Chua, the discoverer of a memristor, theoretically predicted that voltage gated ion channels can be memristors. We recently found memristors in different plants such as the Venus flytrap, Mimosa pudica, Aloe vera, apple fruits, and in potato tubers. There are no publications in literature about the existence of memristors in seeds. The goal of this work was to discover if pumpkin seeds might have memristors. We selected Cucurbita pepo L., cv. Cinderella, Cucurbita maxima L. cv Warty Goblin, and Cucurbita maxima L., cv. Jarrahdale seeds for this analysis. In these seeds, we found the presence of resistors with memory. The analysis was based on cyclic voltammetry where a memristor should manifest itself as a nonlinear two-terminal electrical element, which exhibits a pinched hysteresis loop on a current-voltage plane for any bipolar cyclic voltage input signal. Dry dormant pumpkin seeds have very high electrical resistance without memristive properties. The electrostimulation by bipolar sinusoidal or triangular periodic waves induces electrical responses in imbibed pumpkin seeds with fingerprints of memristors. Tetraethylammonium chloride, an inhibitor of voltage gated K(+) channels, transforms a memristor to a resistor in pumpkin seeds. NPPB (5-Nitro-2-(3-phenylpropylamino)benzoic acid) inhibits the memristive properties of imbibed pumpkin seeds. The discovery of memristors in pumpkin seeds creates a new direction in the understanding of electrophysiological phenomena in seeds.

    Full Text Available The aim of this study was to investigate germination of good bean seed of the variety Galeb and the bad bean seed of the same variety. We were also interested in germination of bean and snap bean seed damaged by grain weevil, and in germination of the seed treated by freezing which was aimed at controlling grain weevil by cold. We also recorded the differences between bean and snap bean seed, which was or was not treated by freezing in laboratory conditions. This investigation was carried out by applying the two factorial block system. The obtained results were evaluated by the variance analysis and x2 test These results suggest that the bean seed of a bad fraction had low levels of germination, but still it was present. Although the seed of good appearance was carefully selected, germination was slightly lower than it should have been. The seed with the large amount of grain weevils performed a high level germination in laboratory conditions. There were no differences in germination between the seed injured by grain weevil either in beans or in snap beans. As for the seed treated or untreated by freezing, there also were no differences between beans and snap beans. .

    Full Text Available Arabidopsis seeds rapidly release hydrophilic polysaccharides from the seed coat on imbibition. These form a heavy mucilage layer around the seed that makes it sink in water. Fourteen natural Arabidopsis variants from central Asia and Scandinavia were identified with seeds that have modified mucilage release and float. Four of these have a novel mucilage phenotype with almost none of the released mucilage adhering to the seed and the absence of cellulose microfibrils. Mucilage release was modified in the variants by ten independent causal mutations in four different loci. Seven distinct mutations affected one locus, coding the MUM2 β-D-galactosidase, and represent a striking example of allelic heterogeneity. The modification of mucilage release has thus evolved a number of times independently in two restricted geographical zones. All the natural mutants identified still accumulated mucilage polysaccharides in seed coat epidermal cells. Using nuclear magnetic resonance (NMR relaxometry their production and retention was shown to reduce water mobility into internal seed tissues during imbibition, which would help to maintain seed buoyancy. Surprisingly, despite released mucilage being an excellent hydrogel it did not increase the rate of water uptake by internal seed tissues and is more likely to play a role in retaining water around the seed.

    Full Text Available Vicia hirsuta (L. Gray S.F. (tiny vetch is a common and persistent segetal weed. Tiny vetch seeds and pods reach different stages of maturity during the crop harvest season. Some seeds that mature before cereal harvest are shed in the field and deposited in the soil seed bank, while others become incorporated into seed material. The objective of this study was to describe selected aspects of tiny vetch seed ecology: to determine the rate of individual reproduction of vetch plants growing in winter and spring grain crops and to evaluate the germination of seeds at different stages of maturity, subject to storage conditions. The seeds and pods of V. hirsuta were sorted according to their development stages at harvest and divided into two groups. The first group was stored under laboratory conditions for two months. In the autumn of the same year, the seeds were subjected to germination tests. The remaining seeds were stored in a storeroom, and were planted in soil in the spring. The germination rate was evaluated after 8 months of storage. Potential productivity (developed pods and flowers, fruit buds was higher in plants fruiting in winter wheat than in spring barley. Vetch plants produced around 17-26% more pods (including cracked, mature, greenish-brown and green pods and around 25% less buds in winter wheat than in spring barley. Immature seeds were characterized by the highest germination capacity. Following storage under laboratory conditions and stratification in soil, mature seeds germinated at a rate of several percent. After storage in a storeroom, seeds at all three development stages broke dormancy at a rate of 72- 75%. The high germination power of tiny vetch seeds stored in a storeroom indicates that this plant can be classified as an obligatory speirochoric weed species.

  14. Effects of rodent species, seed species, and predator cues on seed fate

    2011-07-01

    Seed selection, removal and subsequent management by granivorous animals is thought to be a complex interaction of factors including qualities of the seeds themselves (e.g., seed size, nutritional quality) and features of the local habitat (e.g. perceived predator risk). At the same time, differential seed selection and dispersal is thought to have profound effects on seed fate and potentially vegetation dynamics. In a feeding arena, we tested whether rodent species, seed species, and indirect and direct predation cues influence seed selection and handling behaviors (e.g., scatter hoarding versus larder hoarding) of two heteromyid rodents, Ord's kangaroo rat ( Dipodomys ordii) and the Great Basin pocket mouse ( Perognathus parvus). The indirect cue was shrub cover, a feature of the environment. Direct cues, presented individually, were (1) control, (2) coyote ( Canis latrans) vocalization, (3) coyote scent, (4) red fox ( Vulpes vulpes) scent, or (5) short-eared owl ( Asio flammeus) vocalization. We offered seeds of three sizes: two native grasses, Indian ricegrass ( Achnatherum hymenoides) and bluebunch wheatgrass ( Pseudoroegneria spicata), and the non-native cereal rye ( Secale cereale), each in separate trays. Kangaroo rats preferentially harvested Indian ricegrass while pocket mice predominately harvested Indian ricegrass and cereal rye. Pocket mice were more likely to scatter hoard preferred seeds, whereas kangaroo rats mostly consumed and/or larder hoarded preferred seeds. No predator cue significantly affected seed preferences. However, both species altered seed handling behavior in response to direct predation cues by leaving more seeds available in the seed pool, though they responded to different predator cues. If these results translate to natural dynamics on the landscape, the two rodents are expected to have different impacts on seed survival and plant recruitment via their different seed selection and seed handling behaviors.

    • Premise of the study: Frugivore selection of fruits and treatment of seeds together with seed deposition site are crucial for the population dynamics of vertebrate-dispersed plants. However, frugivore species may influence dispersal quality differently even when feeding on the same fruit species and, while animals disperse some seeds, others simply fall beneath the parent plant.• Methods: In southern Mexico, we investigated to see if within-species seed traits (i.e., length, width, weight, and volume) and germination success differed according to seed source. For five tropical tree species we obtained ingested seeds from two sources, howler monkey (Alouatta pigra) and spider monkey (Ateles geoffroyi) feces; and noningested seeds from two sources, the ground and tree crowns (with predispersed seeds used as control).• Key results: A principal components' analysis showed that traits of seeds ingested by howler monkeys differed from other sources while seeds ingested by spider monkeys were similar to noningested seeds. Howlers consumed on average the larger seeds in Ampelocera hottlei, Brosimum lactescens, and Dialium guianense. Both primate species consumed the smaller seeds in Spondias mombin, while no seed trait differences among seed sources were found in Spondias radlkoferi. For all five tree species, germination rate was greatest for seeds ingested by howler monkeys.• Conclusions: For the studied plant species, seed ingestion by howler monkeys confers higher dispersal quality than ingestion by spider monkeys or nondispersal. Dispersal services of both primate species, however, are not redundant and may contribute to germination heterogeneity within plant populations in tropical forests. © 2014 Botanical Society of America, Inc.

    Full Text Available The effect of sowing dates and harvest dates on yield and quality of white mustard seed been investigated in this study. During the experiment two sowing dates have been tested the first one based on the crops in March, and the other one when the direct sowing was carried out in late May, after the harvest of camomile crops. The harvest of the seed crops in the first seeding date was performed on 1st July, and the second on 15th September. Seed fractioning extracted the following fractions: large (3mm, medium (2 mm and small (1mm. I he objective of the laboratory' experiments was to observe the effect of the seed fraction size on the most important parameters of its quality (germination energy, total germination and absolute mass according to the stipulated terms. Based on the data obtained in the survey, it can be concluded that the seed yield is significantly affected by the varied seeding dates. Earlier seeding date produced significantly increased seed yield (1920 kg/ha than the later seeding date (1160 kg/ha. According to the seed quality parameters, the best characteristics are found in the seed fraction of 3 mm, in both seeding and harvest dates.

    A simple device that uses materials and apparatus commonly available in a radiotherapy department has been designed, fabricated and used in routine quality control relative to the activity uniformity of clinical Ir-192 seeds in ribbons. Detailed evaluation indicated that this system is easy to use and can yield relative activity measurements of individual Ir-192 seeds accurate to within 2%. With this device, activity uniformity of commercial Ir-192 seeds from two manufacturers has been assessed. For the seven shipments of Ir-192 seeds studied, the root mean square variations of individual seed strength from the average of each shipment ranged from 3.4 to 7.1%. Variation in seed activity by more than +- 10% from the average is not uncommon

    2015-01-01

    Mushroom liquid seed production technology was developed by Malaysian Nuclear Agency (Nuclear Malaysia) in the late 1990s. Initially, the liquid seeds were used mainly in the solid state fermentation process for converting oil palm empty fruit bunch fibres into ruminant feed. Considering widespread problems encountered by mushroom growers from use of solid seeds, especially in cases of contaminant agents infecting cultivated bags and inconsistencies in yield, we diverted our focus to utilising liquid seeds as alternative inocula for mushroom cultivation. These problems provide us opportunities to look into the issues and address the problems faced by mushroom growers. However, the technology of producing liquid seed at laboratory scale needs to be primed for commercial production. This paper discusses developmental aspects of mushroom liquid seed at commercial scale for the advancement of the country's mushroom industry. (author)

    In this paper, a new concept 'seed geography' was provided, and its definition, research contents, and scientific issues were put forward. Seed geography is a newly developed interdisciplinary science from plant geography, seed ecology, and phytosociology, which studies the geographic variation patterns of seed biological traits as well as their relationships with environmental factors from macroscopic to microscopic, and the seed formation, development, and change trends. The main research contents would include geography of seed mass, geography of seed chemical components, geography of seed morphology, geography of seed cell biological characteristics, geography of seed physiological characteristics, geography of seed genetic characteristics, and geography of flower and fruit. To explore the scientific issues in seed geography would help us to better understand the long-term adaptation and evolution of seed characteristics to natural environments.

    New experimental designs for the extraction of polyphenols from different seeds including Basil seed, Red seed, Sesame seeds and Ajwan seeds were investigated. Four variables the concentration and volume of methanol and NaOH solutions as well as the temperature and time of extraction were varied to see their effect on total phenol extraction. The temperature was varied in the range from 25 °C to 200 °C while the time in the range from 30 to 200 minutes. Response surface methodology was used to optimize the extraction parameters. The estimation of polyphenols was measured through phenols reduction UV-Vis spectroscopic method of phosphotungstic-phosphomolybdic acids (Folin-Ciocalteu's reagent). Calibration curve was made by using tannic acid as a polyphenols standard in the concentration range from 0.1 to 10 ppm. The regression line obtained shows the value of correlation coefficient i.e. R = 0.930 and Root mean square error of cross validation (RMSEC) value of 0.0654. The Basil seeds were found containing the highest amount of total phenols i.e. 785.76 mg/100 g. While the Sesame seeds having the least amount i.e. 33.08 mg/100 g. The Ajwan seeds and the Red seeds are containing the medium amounts i.e. 379 mg/100 g and 220.54 mg/100 g respectively.

    Full Text Available Peroxiredoxins (Prx are important regulators of the redox status of tree seeds during maturation and long-term storage. Thioredoxins (Trx are redox transmitters and thereby regulate Prx activity. Current research is focused on the association of Trx with Prx in tree seeds differing in the tolerance to desiccation. The results will allow for better understanding the regulation of the redox status in orthodox, recalcitrant, and intermediate seeds. The findings will also elucidate the role of the redox status during the loss of viability of sensitive seeds during drying and long-term storage.

    Full Text Available The studies on root parsley pathogens inhabiting seeds were conducted during 1981-1988 and in 1993. Filter paper method with prefreezing and keeping under light was used. Each test sample comprised 500 seeds. Pathogenicity of collected fungal isolates was tested following two laboratory methods. 238 seed samples were studied. 18 fungal species were found but only 7 proved to be important pathogens of root parsley. The most common inhabitants of root parsley seeds were Alternaria spp. A.allernata occurred on 74,8% of seeds but only a few isolates showed to be slightly pathogenic while A.petroselini and A.radicina were higly pathogenic and inhabited 11,4 and 4,2% of seeds, respectively. The second group of important pathogens were species of Fusarium found on 3,9% of seeds. F.avenaceum dominated as it comprised 48% of Fusarium isolates, the next were as follow: F.culmorum - 20%, F.equiseti - 15%, F.solani - 8%, F.oxysporum - 7% and F.dimerum -2%. Some fungi like Botrytis cinerea, Septoria petroselini and Phoma spp. inhabited low number of seeds, respectively O,4; 0,5 and 0,8%, but they were highly pathogenic to root parsley. The fungi: Bipolaris sorokiniana, Drechslera biseptata, Stemphylium botryosum and Ulocludium consortiale showed slight pathogenicity. They were isolated from 3,8% of seeds.

  9. Microscale Insight into Microbial Seed Banks.

    Microbial dormancy leads to the emergence of seed banks in environmental, engineered, and host-associated ecosystems. These seed banks act as reservoirs of diversity that allow microbes to persist under adverse conditions, including extreme limitation of resources. While microbial seed banks may be influenced by macroscale factors, such as the supply of resources, the importance of microscale encounters between organisms and resource particles is often overlooked. We hypothesized that dimensions of spatial, trophic, and resource complexity determine rates of encounter, which in turn, drive the abundance, productivity, and size of seed banks. We tested this using >10,000 stochastic individual based models (IBMs) that simulated energetic, physiological, and ecological processes across combinations of resource, spatial, and trophic complexity. These IBMs allowed realistic dynamics and the emergence of seed banks from ecological selection on random variation in species traits. Macroscale factors like the supply and concentration of resources had little effect on resource encounter rates. In contrast, encounter rates were strongly influenced by interactions between dispersal mode and spatial structure, and also by the recalcitrance of resources. In turn, encounter rates drove abundance, productivity, and seed bank dynamics. Time series revealed that energetically costly traits can lead to large seed banks and that recalcitrant resources can lead to greater stability through the formation of seed banks and the slow consumption of resources. Our findings suggest that microbial seed banks emerge from microscale dimensions of ecological complexity and their influence on resource limitation and energetic costs.

    Full Text Available The objective of this work was to determine the inheritance mode of seed coat color in sesame. Two crosses and their reciprocals were performed: UCLA37 x UCV3 and UCLA90 x UCV3, of which UCLA37 and UCLA90 are white seed, and UCV3 is brown seed. Results of reciprocal crosses within each cross were identical: F1 seeds had the same phenotype as the maternal parent, and F2 resulted in the phenotype brown color. These results are consistent only with the model in which the maternal effect is the responsible for this trait. This model was validated by recording the seed coat color of 100 F2 plants (F3 seeds from each cross with its reciprocal, in which the 3:1 expected ratio for plants producing brown and white seeds was tested with the chi-square test. Sesame seed color is determined by the maternal genotype. Proposed names for the alleles participating in sesame seed coat color are: Sc1, for brown color; and Sc2, for white color; Sc1 is dominant over Sc2.

    2016-07-01

    Purpose: To evaluate seed placement accuracy in permanent breast seed implant brachytherapy (PBSI), to identify any systematic errors and evaluate their effect on dosimetry. Methods and Materials: Treatment plans and postimplant computed tomography scans for 20 PBSI patients were spatially registered and used to evaluate differences between planned and implanted seed positions, termed seed displacements. For each patient, the mean total and directional seed displacements were determined in both standard room coordinates and in needle coordinates relative to needle insertion angle. Seeds were labeled according to their proximity to the anatomy within the breast, to evaluate the influence of anatomic regions on seed placement. Dosimetry within an evaluative target volume (seroma + 5 mm), skin, breast, and ribs was evaluated to determine the impact of seed placement on the treatment. Results: The overall mean (±SD) difference between implanted and planned positions was 9 ± 5 mm for the aggregate seed population. No significant systematic directional displacements were observed for this whole population. However, for individual patients, systematic displacements were observed, implying that intrapatient offsets occur during the procedure. Mean displacements for seeds in the different anatomic areas were not found to be significantly different from the mean for the entire seed population. However, small directional trends were observed within the anatomy, potentially indicating some bias in the delivery. Despite observed differences between the planned and implanted seed positions, the median (range) V{sub 90} for the 20 patients was 97% (66%-100%), and acceptable dosimetry was achieved for critical structures. Conclusions: No significant trends or systematic errors were observed in the placement of seeds in PBSI, including seeds implanted directly into the seroma. Recorded seed displacements may be related to intrapatient setup adjustments. Despite observed seed

    Sapium sebiferum , an ornamental and bio-energetic plant, is propagated by seed. Its seed coat contains germination inhibitors and takes a long time to stratify for germination. In this study, we discovered that the S. sebiferum seed coat (especially the tegmen) and endospermic cap (ESC) contained high levels of proanthocyanidins (PAs). Seed coat and ESC removal induced seed germination, whereas exogenous application with seed coat extract (SCE) or PAs significantly inhibited this process, suggesting that PAs in the seed coat played a major role in regulating seed germination in S. sebiferum . We further investigated how SCE affected the expression of the seed-germination-related genes. The results showed that treatment with SCE upregulated the transcription level of the dormancy-related gene, gibberellins (GAs) suppressing genes, abscisic acid (ABA) biosynthesis and signalling genes. SCE decreased the transcript levels of ABA catabolic genes, GAs biosynthesis genes, reactive oxygen species genes and nitrates-signalling genes. Exogenous application of nordihydroguaiaretic acid, gibberellic acid, hydrogen peroxide and potassium nitrate recovered seed germination in seed-coat-extract supplemented medium. In this study, we highlighted the role of PAs, and their interactions with the other germination regulators, in the regulation of seed dormancy in S. sebiferum .

  5. Supplementing seed banks to rehabilitate disturbed Mojave Desert shrublands: where do all the seeds go?

    2012-01-01

    Revegetation of degraded arid lands often involves supplementing impoverished seed banks and improving the seedbed, yet these approaches frequently fail. To understand these failures, we tracked the fates of seeds for six shrub species that were broadcast across two contrasting surface disturbances common to the Mojave Desert—sites compacted by concentrated vehicle use and trenched sites where topsoil and subsurface soils were mixed. We evaluated seedbed treatments that enhance soil-seed contact (tackifier) and create surface roughness while reducing soil bulk density (harrowing). We also explored whether seed harvesting by granivores and seedling suppression by non-native annuals influence the success of broadcast seeding in revegetating degraded shrublands. Ten weeks after treatments, seeds readily moved off of experimental plots in untreated compacted sites, but seed movements were reduced 32% by tackifier and 55% through harrowing. Harrowing promoted seedling emergence in compacted sites, particularly for the early-colonizing species Encelia farinosa, but tackifier was largely ineffective. The inherent surface roughness of trenched sites retained three times the number of seeds than compacted sites, but soil mixing during trench development likely altered the suitability of the seedbed thus resulting in poor seedling emergence. Non-native annuals had little influence on seed fates during our study. In contrast, the prevalence of harvester ants increased seed removal on compacted sites, whereas rodent activity influenced removal on trenched sites. Future success of broadcast seeding in arid lands depends on evaluating disturbance characteristics prior to seeding and selecting appropriate species and seasons for application.

    Due to the lack of foliar fungicide use, the organic production of Brassica seeds free of Alternaria spp. is difficult. Therefore, effective seed treatments certified for use in organic farming are needed to eradicate or at least effec­tively reduce the seed-borne inoculum. We here report results of

    Single grain, (RE)BCO (rare earth–barium–copper oxide) bulk superconductors in large or complicated geometries are required for a variety of potential applications, such as in motors and generators and magnetic shielding devices. As a result, top, multi-seeded, melt growth has been investigated over the past 15 years in an attempt to enlarge the size of (RE)BCO single grains specifically for such applications. Of these multi-seeding techniques, so-called bridge-seeding provides the best alignment of two seeds in a single grain growth process. Here we report, for the first time, the successful growth of YBCO (yttrium–barium–copper oxide) using a special, 45°–45°, arrangement of bridge-seeds. The superconducting properties, including trapped field, of the multi-seeded YBCO grains have been measured for different bridge lengths of the 45°–45° bridge-seeds. The boundaries at the impinging growth front and the growth features of the top, multi-seeded surface and cross-section of the multi-seeded, samples have been analysed using optical microscopy. The results suggest that an impurity-free boundary between the two seeds of each leg of the bridge-seed can form when 45°–45° bridge-seeds are used to enlarge the size of YBCO grains. (paper)

    Full Text Available Sapium sebiferum, an ornamental and bio-energetic plant, is propagated by seed. Its seed coat contains germination inhibitors and takes a long time to stratify for germination. In this study, we discovered that the S. sebiferum seed coat (especially the tegmen and endospermic cap (ESC contained high levels of proanthocyanidins (PAs. Seed coat and ESC removal induced seed germination, whereas exogenous application with seed coat extract (SCE or PAs significantly inhibited this process, suggesting that PAs in the seed coat played a major role in regulating seed germination in S. sebiferum. We further investigated how SCE affected the expression of the seed-germination-related genes. The results showed that treatment with SCE upregulated the transcription level of the dormancy-related gene, gibberellins (GAs suppressing genes, abscisic acid (ABA biosynthesis and signalling genes. SCE decreased the transcript levels of ABA catabolic genes, GAs biosynthesis genes, reactive oxygen species genes and nitrates-signalling genes. Exogenous application of nordihydroguaiaretic acid, gibberellic acid, hydrogen peroxide and potassium nitrate recovered seed germination in seed-coat-extract supplemented medium. In this study, we highlighted the role of PAs, and their interactions with the other germination regulators, in the regulation of seed dormancy in S. sebiferum.

  20. Energy cost of seed drying

    2017-11-01

    Full Text Available In this work, the energy costs of drying corn, rice and wheat seeds between 3 drying options were compared. They consisted of 1 two-stage drying by using fluidised bed dryer (FBD in the 1st stage and in-store dryer (ISD in the 2nd stage, 2 single-stage drying by fixed bed dryer (FXD and 3 two-stage drying by using FXD in the 1st  stage and ISD in the 2nd  stage. The drying conditions selected for comparison were proved to be safe for seed viability by the previous studies. The results showed that the drying options 2 and 3 consumed less energy than option 1. However, the benefits from lower energy cost must be weighed against some advantages of using FBD. Furthermore, it appeared that running the burners of FXD and ISD for warming up the ambient air during humid weather condition could shorten drying time significantly with a little higher energy cost.

  1. Seed Anatomy and Water Uptake in Relation to Seed Dormancy in Opuntia tomentosa (Cactaceae, Opuntioideae)

    Orozco-Segovia, A.; Márquez-Guzmán, J.; Sánchez-Coronado, M. E.; Gamboa de Buen, A.; Baskin, J. M.; Baskin, C. C.

    2007-01-01

    Background and Aims There is considerable confusion in the literature concerning impermeability of seeds with ‘hard’ seed coats, because the ability to take up (imbibe) water has not been tested in most of them. Seeds of Opuntia tomentosa were reported recently to have a water-impermeable seed coat sensu lato (i.e. physical dormancy), in combination with physiological dormancy. However, physical dormancy is not known to occur in Cactaceae. Therefore, the aim of this study was to determine if seeds of O. tomentosa are water-permeable or water-impermeable, i.e. if they have physical dormancy. Methods The micromorphology of the seed coat and associated structures were characterized by SEM and light microscopy. Permeability of the seed-covering layers was assessed by an increase in mass of seeds on a wet substrate and by dye-tracking and uptake of tritiated water by intact versus scarified seeds. Key Results A germination valve and a water channel are formed in the hilum–micropyle region during dehydration and ageing in seeds of O. tomentosa. The funicular envelope undoubtedly plays a role in germination of Opuntia seeds via restriction of water uptake and mechanical resistance to expansion of the embryo. However, seeds do not exhibit any of three features characteristic of those with physical dormancy. Thus, they do not have a water-impermeable layer(s) of palisade cells (macrosclereids) or a water gap sensu stricto and they imbibe water without the seed coat being disrupted. Conclusions Although dormancy in seeds of this species can be broken by scarification, they have physiological dormancy only. Further, based on information in the literature, it is concluded that it is unlikely that any species of Opuntia has physical dormancy. This is the first integrative study of the anatomy, dynamics of water uptake and dormancy in seeds of Cactaceae subfamily Opuntioideae. PMID:17298989
