ABSTRACT


The composition of leaf cuticular neutral lipids of Amphoricarpos autariatus ssp. autariatus collected at canyon of river Tara (North Montenegro) was investigated by GC/MS (nonpolar fraction), LC-ESI TOF MS and 1H NMR spectroscopy (more polar fraction). The nonpolar fraction (ca. 15% of the whole surface extract) contained C 27 - 33 n-alkanes, those with odd-number of carbons predominating. The LC-ESI MS and 1H NMR of the more polar fraction revealed 13 sesquiterpene lactones, constituting ca. 97.5% of the lactone mixture, identified as the known guaianolides, so-called amphoricarpolides, found previously in the aerial parts of the genus. The lactone fraction exhibited considerable in vitro effect against eight fungi, i.e. Aspergillus ochraceus , A. nigerA. versicolor , Penicillium funiculosumP. ochrochloronTrichoderma virideFusarium verticillioides and Fulvia fulvum.
