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.
