Objective: This study investigates the potential estrogenic activity of the ethanolic extract of Flemingia vestita Benth tubers using ovariectomized rat model. Materials and Methods: The ethanolic extract of F. vestita tubers has been standardized using validated HPLC method in terms of its genistein content (8.43 \± 0.05 mg/g of extract). Three to four week old young albino Wistar female rats were ovariectomized and treated for 14 days post ovariectomy with the standardized ethanolic extract at three different dose levels (100, 250, 500 mg/kg body weight) with a positive control of Estradiol valerate (1 mg/kg/day). The parameters evaluated were uterine weight, uterine glycogen, G6PDH, LDH, 17\β-estradiol, progesterone, total cholesterol, triglycerides, HDL and histo architecture of uterus. Results: Treatment with the ethanolic extract of F. vestita tubers showed dose dependent increase in uterine weight, glycogen levels, G6PDH levels, estrogen and progesterone levels when compared with the ovariectomized control. Amongst three dose levels, high dose of plant extract showed significant increase in the uterine weight (p \< 0.001), uterine glycogen content (p \< 0.001), 17-\β estradiol and progesterone levels (p \< 0.001), G6PDH and LDH levels (p \< 0.001) as well as significant decrease in HDL and triglycerides levels (p \< 0.001) compared to ovariectomized control. Histopathological evaluation of uteri sections revealed that the high dose of the plant show increase in the endometrial response as indicated by proliferation of endometrial glands and luminal epithelium of the ovariectomized rats. Conclusion: Thus, these data suggests that ethanolic extract (500 mg/kg body weight) of F. vestita tubers may exhibit good estrogenic activity in ovariectomized rat model.

Introduction: Eclipta alba Linn. (Asteraceae) is an important ingredient of several Ayurvedic formulations. The monograph on different parts of plant like flowers, leaves, roots are listed in Ayurvedic pharmacopeia of India. The plant is reported to be effective for broad range maladies like inflammation, reproductive problems of females etc. It is also used as a hepatoprotectant, analgesic, antibacterial and antidiabetic agent. Wedelolactone is used as a bioactive marker to establish the quality of the crude drug and its formulations. In the present study, wedelolactone-based standardization of Eclipta alba and its quantitation from marketed herbal and Ayurvedic formulations has been documented using RP-HPLC. Methods: In the current work, an isocratic method has been developed and validated to quantitate wedelolactone from whole plant of Eclipta alba. This method is validated as per ICH guidelines and is used to quantitate the content of wedelolactone in polyherbal formulations like Liv52, Geriforte, Mahabhringaraj oil etc. Results: The LOD is found to be 0.5 \μg/mL and the LOQ is 1 \μg/mL. The linearity range of response is from 5 \μg/mL to 100 \μg/mL. Conclusion: The validated method is found to be simple, sensitive, accurate, rugged and reproducible. This developed method can be recommended for quality assurance and marker-based standardization of polyherbal formulations containing whole plant of Eclipta alba.
