Popis:	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 H-1 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 H-1 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. niger, A. versicolor, Penicillium funiculosum, P. ochrochloron, Trichoderma viride, Fusarium verticillioides and Fulvia fulvum.
