Abstract

Eight new lanostanoids, 12alpha,15beta-dihydroxy-3,7,11,23-tetraoxolanost-8,(20Z)(22)-dien-26-oic acid (1), 7beta,8beta-epoxy-15beta,20S-dihydroxy-3,12,23-trioxolanost-9(11),16-dien-26-oic acid (2), 7beta,8beta-epoxy-3beta,15beta,20S-trihydroxy-12,23-dioxolanost-9(11),16-dien-26-oic acid (3), 7beta,8beta-epoxy-2alpha,3beta,15beta,20S-tetrahydroxy-12,23-dioxolanost-9(11),16-dien-26-oic acid (4), 7beta,8beta-epoxy-3beta,15beta,20S,28-tetrahydroxy-12,23-dioxolanost-9(11),16-dien-26-oic acid (5), 7beta,8beta-epoxy-3beta,15beta,19,20S-tetrahydroxy-12,23-dioxolanost-9(11),16-dien-26-oic acid (6), 8beta,15beta,20S-trihydroxy-3,7,12,23-tetraoxolanost-9(11),16-dien-26-oic acid (7), 7alpha,8alpha-epoxy-15beta,23xi-dihydroxy-12-oxo-3,4-secolanost-4(28),9(11),(20Z)(22)-trien-3,26-dioic acid (8), and the methyl ester of 8 (8a) were isolated from the fruit bodies of Elfvingia applanata. Their structures were established primarily by NMR experiments, and their biological activity against Kato III and Ehlrich cells was investigated.
