Sterols and triterpenes in Viburnum opulus L. leaves

IZABELA RYCHLIŃSKA

Abstract

Ursolic acid and β-sitosterol were isolated from Viburnum opulus L. leaves with the use of column chromatography. Their structure was determined by spectroscopic methods (IR , NMR ). Other sterols and triterpenes in fractions obtained from benzine and chloroform extracts from V. opulus L. leaves were examined using TLC, GC, GC/MS methods. Following triterpenes there were identified: α-amyrin, β-amyrin, as well as sterols: campesterol, stigmasterol, β-sitosterol. The qualitative analysis of benzine and chloroform extract from V. opulus L. flowers has indicated the presence of β-sitosterol and ursolic acid.
