AB  - Two new guaianolides, i.e. anthemolide B and 8-O-angeloyl-9-O- acetylanthemolide B, in addition to 12 known closely related guaianolides were identified in the aerial parts of the flowering plant Anthemis cretica subsp. cretica.

AB  - A new guaianolide, 3-deacetyl-9-O-acetylsalograviolide A, along with four known closely related lactones, salograviolide A, 9-O- acetylsalograviolide A, kandavanolide and salograviolide B were detected in the aerial parts of the flowering plant Centaurea nicolai. Antifungal tests performed on salograviolide A and its 9-O-acetyl and 3-O-deacetyl-9-O-acetyl derivatives revealed inhibitory activity against Aspergillus niger, A. ochraceus, Penicillium ochrochloron, Cladosporium cladosporoides, Fusarium tricinctum and Phomopsis helianthi. Neither of them was active against Trichoderma viride.

AB  - The isolation of two oxidation products of hyperforin from the aerial parts of Hypericum perforatum and their structure determination by means of 2D NMR methods is reported. The products had the same 1-(2-methyl-1- oxopropyl)-2,12-dioxo-3,10β-bis(3-methyl-2-butenyl)-11β-methyl-11α-(4- methyl-3-pentenyl)-5-oxatricyclo[6.3.1.0 4,8 ]-3-dodecene skeleton. In addition, one of them, with the same number of carbons as hyperforin (C 35 H 52 O 5 ), contained a 1-methyl-1-hydroxyethyl group in the 6β- position, whereas the other compound (a hemiacetal, C 32 H 46 O 5 ), presumably a degradation product of hyperforin, exhibited a 6-hydroxy function. The latter was an inseparable mixture of 6α- and 6β-hydroxy epimers undergoing (according to phase sensitive NOESY) mutual interconversion.
