Oxidative stress has a crucial role in the progression of diabetes and its complications. Soluble fibre-rich fenugreek seeds (Trigonella foenum-graecum L.) are understood to have a beneficial effect in the management of diabetes. Previously, we have shown that the amelioration of diabetic hyperglycemia and related metabolic abnormalities was potentiated by onion (Allium cepa L.) in experimental rats. The present study evaluated the additive beneficial effect of dietary fenugreek seeds (10%) and onion (3%) on oxidative stress in diabetic rats. These dietary interventions lowered oxidative stress, the combination producing a higher beneficial effect (p < 0.05), although not additive. Dietary fenugreek, onion, or fenugreek+onion countered hypercholesterolemia (p < 0.05), especially from low-density lipoprotein−associated fraction by 43%, 35%, and 54%, respectively. Elevated concentrations of cholesterol and triglycerides in the liver and heart under diabetic conditions were significantly counteracted by these dietary interventions, with the additive combination resulting in greater effect. These findings were also corroborated by restoration of histopathological abnormalities of heart and liver tissues along with lowered heart and liver weights. It is inferred that an alleviation of oxidative stress contributes further to the antidiabetic influence and this nutraceutical potential of fenugreek seeds and onion was higher when consumed together.

Objective: The objective of this study is to investigate the estrogenic and antiestrogenic activity of Fenugreek seeds, Trigonella foenum-graecum L. in the estrogen-dependent breast cancer cell line, MCF-7, including its effect on the expression of estrogen-dependent presenilin 2 (pS2) gene.Methods: An activity guided fractionation was carried out with extracts from fenugreek seeds in MCF-7 cells. Cytotoxic activity assays were conducted with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay. Most fractions were also tested also tested in media with estradiol 10 nM We also analysed the expression of pS2 gene. For the analysis of pS2 gene expression we employed PCR primers for pS2 and for β-actin as a housekeeping gene using real-time polymerase chain reaction (RT-PCR).Results: Based on cytotoxic activity assay in MCF-7, the active fractions are ethyl acetic fraction and its phases ethyl acetic (EA) 2 and EA 2.2. The most active fraction was EA 2.2 (IC50=27.129 ppm), which exhibited a biphasic effect; at low concentrations, it stimulated the growth, and at high concentrations it showed strong cytotoxic effects. EA2.2 fraction in concentration 20 ppm, also could induce pS2 gene expression in media with and without estrogen.Conclusion: The most active fraction was the ethyl acetate phase and further subfractions. The most active fraction also induced the expression of pS2 gene which was studied by RT-PCR.

Separation of Trigonelline, the major alkaloid in fenugreek seeds, is difficult because the extract of these seeds usually contains Trigonelline, choline, mucilage, and steroidal saponins, in addition to some other substances. This study amis to isolate the quaternary ammonium alkaloid (Trigonelline) and choline from fenugreek seeds (Trigonella-foenum graecum L.) which have similar physiochemical properties by modifying of the classical method. Seeds were defatted and then extracted with methanol. The presence of alkaloids was detected by using Mayer's and Dragendorff's reagents. In this work, trigonilline was isolated with traces of choline by subsequent processes of purification using analytical and preparative TLC techniques. Further identification was done by using HPLC, IR and MP. Pure Trigonelline was isolated from the seeds of Trigonella-foenum graecum excluding other alkaloid like choline. In this study, a new, fast and convenient method for isolation and purification of Trigonelline from fenugreek seeds has been established. Unlike other methods, this one excludes all the non-alkaloidal components from the fenugreek seeds extract.

Protective effects of Fenugreek seeds (Trigonella foenum graecum L), added in the diet, upon oxidative stress and dysfunctions in kidney, thyroid and liver of alloxan-diabetic rats were investigated.In our study, the alloxan-induced diabetes triggered 1) increased levels of glucose, total cholesterol and triglycerides in blood, 2) increased activities of alkaline phosphatase and transaminases in blood, 3) increased levels of creatinine, urea and protein in blood, 4) a decreased level of TSH and an increased level of free thyroxin in plasma.In addition, an oxidative stress, evidenced by an increase of lipids peroxidation level and superoxide dismutase activity associated with a decrease of glutathione peroxidase and catalase activities in hepatic and renal tissues, was observed.When Fenugreek seeds powder (100g/kg) was added in the food for 30 days, all this parameters were significantly shifted to more normal values.In conclusion, fenugreek seeds powder displays beneficial effects upon hepatotoxicity, nephropathy, thyroid dysfunction and oxidative stress in alloxan-diabetic rats. This property could be attributed to the presence of antioxidant components, such as complex polysaccharides and phenolic acids, as confirmed by analyses.

Trigonella foenum-graecum L. is a widely used herb in traditional medicine. The aim of this study was to evaluate the genetic polymorphisms in fenugreek plants following the treatment of fenugreek seeds with different combinations of biotic and abiotic agents using the random amplified polymorphic DNA (RAPD)-PCR technique. We assessed the effects of two strains of the fungus Trichoderma harzianum (Th-1 and Th-2), methyl jasmonate (MeJA), and Aloe vera gel (AVG) on growth parameters of fenugreek plants. Combinations of Th-1, MeJA, AVG significantly increased fenugreek root length, shoot length, shoot fresh weight, number of true leaves, and chlorophyll content. The Th-2 isolate, on the other hand, markedly slowed plant development (except for root length which was not affected significantly). In contrast, the combination with MeJA had no considerable effect on all growth measures, whereas the combination with VAG resulted in a substantial drop in shoot height and chlorophyll content when compared to other growth parameters that were unaffected. The present study has shown that the PCR amplification of DNA, using five primers for RAPD analysis, produced 62 DNA fragments that could be scored in all genotypes. The total number of polymorphic bands was 26, and the average percentage of polymorphism was 54.21%. The RAPD-PCR results showed that the treatment of fenugreek seeds with Th-1 alone or in combination with MeJA and AVG induced polymorphisms in fenugreek leaves.

Introduction: Trigonella foenum-graecum L. (Fenugreek) seeds and Cordia myxa fruits have been known as agents with anti-diabetes effects in Iranian traditional medicine. We compared the effects of aqueous extracts of these plants on diabetes-induced cognitive dysfunction. Methods: In our study, rats were equally allocated to 4 groups (n=12/group) as follows: control; diabetic; diabetic rats treated with T. foenum graecum seeds extract (TE) (870 mg/kg BW); and diabetic rats treated with C. myxa fruit extract (CE) (500 mg/kg BW) for 30 days. Diabetes was induced by alloxan (120 mg/kg BW, ip). Cognitive dysfunction was determined through memory task and passive avoidance learning (PAL). Results: Diabetes resulted in cognitive impairment in PAL and memory task. CE and TE significantly reduced serum blood sugar (P<0.05) and brain lipid peroxidation (P<0.001). Moreover, treatment with both extracts prohibited learning and memory deficits in diabetic groups in comparison to the non-treated group; however, there was no significant difference between the groups that were treated with TE or CE. Conclusion: Aqueous extract of fenugreek seeds and C. myxa are effective in preventing diabetesinduced lipid peroxidation and memory loss in animal models of diabetes.
