Studies on the Neutral Constituents of Pachysandra terminalis SIEB. et ZUCC.I. : Isolation and Characterization of Sterols and Triterpenes

Abstract

Neutral components of the alcoholic extracts from Pachysandra terminalis SIEB. et ZUCC. (Buxaceae) were submitted to alkaline hydrolysis and systematic examination was made on the benzene-soluble part of the neutral fraction thus obtained. Several kinds of sterols, friedelin-type triterpenes, and cycloartenol-type triterpenes were isolated in crystalline form and characterised.
