Description (eng)

The aim of this doctoral dissertation was the estimation of chemotaxonomic utility of secondary metabolites of the selected members from the genus Sedum L. (Crassulaceae), collected from the Central Balkan Peninsula. The study also included compatriots from the related genera (same family): Crassula L., Hylotelephum H. Ohba, Echeveria DC. and Kalanchoe Adans. Distribution of n-alkanes (C20-C35) and tirterpenes (olenanae, lupane and taraxerane) were monitored in hexane extracts by GC-MS and GC-FID techniques, while polar components, from methanol extracts, were monitored by HPLC technique. The contents of mentioned components were inputted uniformly in matrices (pattern) further used in statistical analyses: descriptive, univariate and multivariate methods. Distribution of characters was considered on the series level as a taxonomic rank. Different contents contributed to certain classification of examined taxa which was discussed with respect to already established systems of classification related to genus.
