Four New Cucurbitane Glycosides from Hemsleya jinfushanensis

Abstract

A phytochemical study of the tubers of Hemsleya jinfushanensis L. T. Shen resulted in the isolation of four new cucurbitane glycosides, jinfushanosides A - D (1 - 4), as well as four known compounds 5 - 8. Compounds 1 - 7 were tested for bioactivity against rabbit platelet aggregation induced by PAF, ADP, or AA. Among them, compounds 1, 5, 6 and 7 weakly inhibited PAF-induced platelet aggregation.
