Abstract

Triterpenoid distribution in epicuticular waxes of 20 central Balkan Sedum L. species and four out-groups of genera: Hylotelephium H. Ohba, Crassula L., Echeveria DC., and Kalanchoe Adans. were investigated for chemotaxonomic purposes. Identification and quantification of wax triterpenoids were performed by GC/MS and GC-FID analyses. Distribution of identified triterpenoids (oleanane, lupane, and taraxerane series), as a pattern in statistical analysis, indicated very good agreement with phylogeny and systematics, except members of series Rupestria Berger, in which case the distribution of triterpenoids did not support known classification in a satisfactory manner. According to the obtained clustering, Kalanchoe is shown as similar to Sedum samples, while the other out-groups were clearly separated.
