Abstract PIP: The plant kingdom might yield an effective antifertility drug. A Mentha arvensis L. (Labiatae) fraction with uterotonic activity was isolated, and was found to be active on the nonpregnant as well as the pregnant rat uterus. According to folklore medicine, the Mexican plant Montanoa tomentosa Cerv. (zoapatle) possesses antifertility activity in women. The effect of various isolated preparations from this plant on early pregnancy were investigated in serveral rodent species including the mouse, rat hamster, and guinea pig. It was concluded that zoapatle plant extracts possess unique antifertility activity. Lin-Hsim and coworkers isolated fractions from Aristolochia molissima Hanceith contrceptive activity in female mice. Saponins of some plants were used in contraceptive formulations either as foaming agents or as spermicidal substances. Elbary and Nour investigated the spermicidal effects of saponins isolated from the following plants: Gypsophila paniculata L., Saponaria officinalis L., Enterolobium cyclocarpum, Griseb., Terminalia horrida Steud., Melilotus sicula Vitm., and Ruscus hypoglossum L. All of the saponins tested possessed spermicidal activity. Jain and coworkers isolated 2 new saponins in Pittosporum nilghrense with spermicidal effects. In this paper we have determined the spermicidal activity of saponins isolated from some Yugoslav plants, which in that aspect have not been investigated. The results are illustrated in the table. They show that all of the saponins tested were spermicidal in dependence on their nature. Saponins of Primula vulgaris Huds. and Cyclamen persicum Mill. immobilized human spermatozoa within a period of 20 s at a dilution 1:1000. Saponin of Gypsophila paniculata L. was spermicidal at dilution 1:20. These findings show that saponins isolated from some Yugoslav plants may be useful spermicides of natural origin.
