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. Abstractde Wirkung von Polianthes tuberosa (Amaryllidaceae) auf die Reproduktion und biochemische Parameter der Zwitterdrüsen der Schnecke Lymnaea acuminata (Mollusca, Pulmonata) Die Untersuchungen belegen eine deutliche Wirkung des Ethanolauszuges aus den Knollen von Polianthes tuberosa (Amaryllidaceae) und der in ihm enthaltenen Sapogenine Tigogenin und Hecogenin auf die Reproduktion der Schnecke Lymnaea acuminata (Mollusca, Polmonata). Der Ethanolauszug wie die beiden Sapogenine verursachen eine signifikante Reduktion der Fruchtbarkeit, der Schlüpfrate und der Überlebensrate der jungen Schnecken. Außerdem ergibt sich durch die mehrtägige Exposition gegenüber subletalen Konzentrationen der drei Agenzien eine geringe, aber signifikante Verminderung der Gehalte an Protein, Aminosäuren, Nucleinsäuren und der Phosphataseaktivitäten im Gonadengewebe der exponierten Schnecken. Bei Abbruch der Exposition tritt innerhalb von sieben Tagen eine vollständige Erholung der Schnecken und ihrer Reproduktion sowie der biochemischen Parameter auf Normalwerte auf. Die möglichen Wirkungsmechanismen des molluskiziden Effektes der Stoffe werden diskutiert. Citing Literature Volume27, Issue1January 1999Pages 32-37 RelatedInformation
