Two New 3,4-Seco-Lanostane-Type triterpenes, Named as 15-hydroxy. -3,4-seco-lanosta-4 (28), 8,24-triene-3,21-dioic acid (1), 5-hydroxy-3,4-seco-lanosta-4 (28), 8,24. -triene-3,21-dioic acid 3-methyl ester (2), and one new lanostane triterpene 15-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.
