  • The hypoglycemic and hypolipidaemic effects of fenugreek seeds (Trigonella foenum graecum) are well established. Owing to the wide spread use of the seeds by healthy individuals and by diabetic patients we wanted to test whether the seeds can affect biological systems such as membrane transport function. In the present study fenugreek seed polyphenols were extracted and their effect on erythrocyte membrane-bound sodium-potassium adenosine triphosphatase $(Na^+/K^+-ATPase)$ activity was studied in vitro. Fenugreek seed polyphenols inhibited $Na^+/K^+-ATPase$ in erythrocyte membrane of diabetic and normal subjects. Maximum inhibition was observed at $100\;{\mu}l$ of extract containing 0.75 mM gallic acid equivalents. The uncoupling of membrane ATPases in vitro suggest that polyphenols from fenugreek seeds may possess a positive inotropic effect.

  • Objectives : We proposed the hypothesis that administering Trigonella foenum-graecum seed extract (TSE) could alleviate menopausal symptoms and osteoporosis resulting from estrogen deficiency. Methods : Ovariectomized (OVX) rats were administered TSE at doses of 300 or 600 mg/kg body weight for 8 weeks, followed by measurement of serum lipid profile and serum bone markers using ELISA kits. Additionally, analysis of related genes in the femur and uterus was performed using Western blot and real-time PCR. Additionally, micro-CT analysis was performed to investigate the protective effect of TSE against bone loss due to oophorectomy. Results : The administration of TSE led to significant reductions in triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL) cholesterol, and glucose levels in the serum of OVX rats. Furthermore, TSE increased estradiol levels in the serum and notably improved the levels of biochemical markers associated with bone metabolism. Additionally, TSE exerted significant regulatory effects on the mRNA levels of alkaline phosphatase (ALP) and receptor activator of nuclear factor kappa-B ligand (RANKL)-genes closely associated with bone metabolism in the femur. TSE also demonstrated pronounced effects on uterine tissue, with improvements observed in gene expression related to estrogen receptors. Conclusion : Our findings confirm the efficacy of TSE in ameliorating menopause symptoms by modulating elements associated with both bone and lipid metabolism in the serum, uterine tissue, and femur of OVX rats. The present findings suggest that TSE may offer potential therapeutic effects for symptoms related to menopause and osteoporosis in females.

  • 본 연구는 건강기능식품 호로파종자식이섬유 중 4-hydroxyL-isoleucine에 대한 분석법을 개발하는 연구이다. 최적분석 조건을 확립하기 위해 시료 채취량, 전처리 용매 및 이동상 용매 조건을 비교 검토하였으며, HPLC-PDA를 이용하여 시료 중의 4-hydroxy-L-isoleucine를 분석하였다. 분석 시 사용한 컬럼은 Capcell Pack UG120 C18 (Shiseido, 4.6×250 mm, 5 ㎛)이며, 유도체 시약으로 OPA를 선정하였다. 확립된 시험법에 대해 특이성, 직선성, 검출한계, 정량한계, 정확성, 정밀성 등의 밸리데이션을 수행하였다. 5-100 ㎍/mL 농도에서 결정계수(R2) 0.999 이상으로 높은 직선성을 확인하였다. 또한, 회수율은 91.7-96.4%이었고, 정밀성은 0.5-1.1%의 상대표준편차(%RSD)를 확인하였다. 개발된 시험법은 호로파종자추출물 중 4-hydroxy-L-isoleucine 분석을 위한 시험법으로 활용되기에 적합한 것으로 판단된다.
