Abstract

From the aerial parts of A. melanolepis, two new sesquiterpene lactones, melanolepin B (= 1alpha ,4beta ,8alpha -trihydroxyeudesm-11(13)-en-12,6alpha -olide; 1) (I) and melanolepin C (= 1alpha ,10beta -epoxy-8beta -hydroxygermacra-4(15),11(13)-dien-12,6alpha -olide; 2), were isolated, together with four known compds., desacetyllaurenobiolide, dentatin A, taraxasterol, and (3S,5R)-loliolide. Compd. 1 was found to have the rare cis-fused eudesmane skeleton. The structures of the isolated compds. were established by means of NMR (1H, 1H-COSY, 1H, 13C-HSQC, HMBC, NOESY) and MS analyses.
