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.

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.

Diabetes is a life-threatening metabolic disorder. This study was undertaken to evaluate the antihyperglycemic and antioxidative potential of seed powder of Trigonella foenum-graecum L in alloxan (55 mg/kg) induced diabetic rats. The results obtained showed that extensive oxidative stress is generated in tissues of diabetic rats as evidenced by increased production of hydrogen peroxide, increased accumulation of malondialdehyde (MDA) and 4-hydroxynonanal (4HNE) and decreased activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) in tissues of diabetic rats. It was observed that the transcription of genes of SOD, GPx, and CAT was also significantly decreased when compared with control. Treatment of Trigonella for 15 days to diabetic rats showed hypoglycemic effect and improved the altered levels of H2O2, MDA, and 4HNE, the activities of SOD, GPx, and CAT as well as transcription of these genes in the liver and the brain of diabetic rats.

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.

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.
