| Abstract: | Two novel lanostane-type triterpenes, Ganolactone B and Ganoderiol A triacetate, were isolated from the fruiting bodies of G. sinense, together with six known compounds. The structures of the two new triterpenes were determined as 3beta,7beta- dihydroxy-11,15-dioxo-lanosta-8-en-24-->20 lactone (1) and 3beta,24,26-triacetoxy-5alpha-lanosta-7,9(11)-dien-25-ol (2), respectively, by chemical and spectroscopic means. |
