Background: To study the antidiabetic effects and mechanisms of the fenugreek extracts in streptozotocin (STZ)-induced type 2 diabetic (T2DM) mice fed a high-fat diet (HFD).
Methods: We established C57BL/6J mice model of T2DM using HFD-fed and STZ-induced method. Then, the mice were administered with two types of fenugreek extracts (E1, flavonoid and E2, stilbene glycoside) for 4 weeks and the effects on fasting blood glucose (FBG), weight, superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and pathological indexes were investigated.
Results: Administration of fenugreek extracts decreased the FBG level compared with that of the model group. Comparatively, the high-dose E2 decreased the FBG more significantly than the other treatments did. Both extracts showed an obvious antioxidant effect by increasing serum SOD and CAT activities and decreasing the MDA content. Furthermore, the high-dose E1 showed a significant difference (< .01) compared with the model group in the three investigated indexes.
Conclusion: Our study demonstrated that both the flavonoid and stilbene glycoside extracts of fenugreek improved the hyperglycemia in the T2DM mice model. Moreover, the antidiabetic effects of both extracts might be due to their antioxidant activity in vivo.

Introduction Insulin resistance is a fundamental factor in the pathogenesis of polycystic ovarian syndrome (PCOS) and has been found to mediate a close association with obesity and dyslipidemia. While the anti-diabetic and anti-inflammatory properties of fenugreek seed extracts have been demonstrated, research on its anti-hyperlipidemic properties is still in its novice stage, with inconclusive evidence. The present study assessed the impact of fenugreek seed extracts rich in furostanolic saponins (Furocyst) on lipid profiles across different categories of body mass index (BMI) in women with PCOS.

This study investigates the removal of ibuprofen and diclofenac from aqueous media via a fully pressurized dissolved air flotation system, enhanced by fenugreek-derived saponin, a plant-based biosurfactant. The use of fenugreek saponin in flotation processes distinguishes this work from previous studies as it offers an ecofriendly and efficient alternative to chemical surfactants. The biosurfactant's surface-active properties were confirmed through FT-IR, UV-vis spectroscopy identified key functional groups and structural characteristics of the saponin, NMR provided molecular insights into its bioactive components, and surface tension analyses demonstrated its ability to reduce interfacial tension, indicating effective surfactant behavior.

Article Synopsis
- This study explores the use of cyclopentyl methyl ether (CPME) as a more efficient and environmentally friendly alternative to hexane for extracting fenugreek seed oil.
- In simulations and experiments, CPME outperformed hexane, yielding 7.23% oil compared to hexane's 4.25% and preserving more beneficial fatty acids and bioactive compounds.
- CPME also demonstrates better oxidative stability and lower volatile organic compound emissions, making it a sustainable option for oil extraction while offering improved antioxidant and antibacterial properties.
