title: Further amphoricarpolides from the surface extracts of Amphoricarpos complex from Montenegro.
abstract: Analysis of composition of sesquiterpene lactone fraction of leaf cuticular neutral lipids of Amphoricarpos complex from two different localities in north Montenegro, i.e., canyon of river Tara (A. autariatus ssp. autariatus) and mountain Zeletin (A. autariatus ssp. bertisceus) afforded sesquiterpene lactones with guaianolide skeletons (17 compounds), so called amphoricarpolides, typical for this genus. Nine of them, 9-17, were new compounds, and their structures were elucidated by detailed analyses of IR, NMR, and MS data.
