摘要：In this study, twenty seven (27) female albino rats were used in the determination of contraceptive effect of oral administration of aqueous suspension of Ricinus communis seed. Estrogen and progesterone levels of these rats were analysed using electrochemiluminescent method. The result revealed estrogenic property of the aqueous suspension of R. communis seed, which is partly attributed to the anticonceptive effect of the seeds. The estrogenic activity was high with 107×10 -2 mg/kg dose administered after 48hours and 7 days respectively, indicating some degree of dose-dependency. In addition, alteration of estrogen/progesterone balance as indicated by this study may be responsible for the contraceptive effect of aqueous suspension of R. communis seed.
