| pubmed-article:15270562 | pubmed:abstractText | Four new lanostane-type triterpenes were isolated from the MeOH extract of the fruiting bodies of Ganoderma applanatum. Their structures were established as 3beta,7beta,20,23xi-tetrahydroxy-11,15-dioxolanosta-8-en-26-oic acid (1), 7beta,20,23xi-trihydroxy-3,11,15-trioxolanosta-8-en-26-oic acid (2), 7beta,23xi-dihydroxy-3,11,15-trioxolanosta-8,20E(22)-dien-26-oic acid (3), and 7beta-hydroxy-3,11,15,23-tetraoxolanosta-8,20E(22)-dien-26-oic acid methyl ester (4), respectively, by extensive spectroscopic analyses. | lld:pubmed |
