| Abstract: | The present study elucidates the effect of powder of Polianthes tuberosa bulb and its sapogenins tigogenin and hecogenin on the reproduction of the snail Lymnaea acuminata. It has been reported that the two sapogenins tigogenin and hecogenin caused a significant reduction in fecundity, hatchability, and survival of young snails. Exposure to sublethal concentration caused a small but significant reduction in protein, amino acids, nucleic acids, and phosphatase activities in gonadal tissue of treated snails. Withdrawal after 7 days indicates that the effect of powder of P. tuberosa bulb, tigogenin, and hecogenin on the reproduction and different biochemical parameters is reversible. |
