Abstract

A novel quassinoid glucoside picrasinoside-A was isolated from Pierasma ailanthoides PLANCHON and the structure was established from spectral data, chemical transformations into picrasin B and quassin, and enzyme hydrolysis. The aglycon picrasin B showed a significant clastogenic activity in cell cultures of Don lung cells of Chinese hamster.
