ABSTRACT

Two new 3,4-seco-lanostane-type triterpenes, named as 15α-hydroxy-3,4-seco-lanosta-4(28),8,24-triene-3,21-dioic acid (1), 5α-hydroxy-3,4-seco-lanosta-4(28),8,24-triene-3,21-dioic acid 3-methyl ester (2), and one new lanostane triterpene 15α-acetoxylhydroxytrametenolic acid (3) together with a known one versisponic acid D (4) were isolated from the fruiting bodies of Laetiporus sulphureus var. miniatus. Their structures were determined on the basis of extensive spectroscopic methods and comparison with reported data. All four compounds were evaluated for their cytotoxicities against five human cancer cell lines; however, none exhibited inhibitory effects.
