Objective : To evaluate the effect of petroleum ether (60-80), chloroform, acetone, ethanol and aqueous extracts of Plumbago rosea leaves on the estrous cycle and to identify the estrogenic activity of active acetone and ethanol extracts in female albino rats. Methods : Plant extracts were tested for their effect on the estrous cycle at two dose levels: 200 and 400 mg/kg, respectively. The effective acetone and ethanol extracts were further studied on estrogenic activity in rats. Histological studies of the uterus were carried out to confirm their estrogenic activity. Results : The acetone and ethanol extracts were most effective in interrupting the normal estrous cycle of the rats (P<0.05, <0.01, <0.001). These later exhibited prolonged diestrous stage of the estrous cycle with consequent temporary inhibition of ovulation. The antiovulatory activity was reversible on discontinuation of treatment. Both the extracts showed significant estrogenic and antiestrogenic activity. Conclusion : The acetone and ethanolic extracts of P. rosea leaves have an antifertility activity.
