Abstract
Two new lanostanoid triterpenes named 3β-hydroxy-4,4,14-trimethyl-7,11,15-trioxochol-8-en-24-oic acid (1) and 3β-hydroxy-7,11,12,15,23-pentaoxo-lanost-8-en-26-oic acid (2) were isolated from the fruit bodies of Ganoderma lucidum, which is the major component of the antitumor product SunRecome®. Their cytotoxic activities were assayed in vitro against HeLa, p388, SGC-7901, BEL-7402 cell lines, and the results showed that 1 had IC50 values of 18.00 μM against p388 cell, 12.70 μM against Hela cell, 22.00 μM against BEL-7402 cell, 1.50 μM against SGC-7901 cell and 2 had IC50 values of 9.85 μM against p388 cell, 17.10 μM against Hela cell, 51.00 μM against BEL-7402 cell, 42.00 μM against SGC-7901 cell.
