Abstract

One new triterpene, 24-ene-2′-methyl carboxy acetylquercinicate, and 3 known compounds were isolated from the ethyl acetate extract of the fruiting bodies of Trametes orientalis (Yasuda) Imazeki. Their structures were elucidated by means of extensive spectroscopic analysis and compared with data reported in the literature. Furthermore, they were evaluated for their cytotoxicity against 5 human cancer cell lines in vitro. Compound 4 showed significant cytotoxicity, especially to the leukemic HL-60 cell line (IC50 = 1.77 ± 0.07 μM), while compounds 1-3 showed significant cytotoxicity to SMMC-7721 (hepatoma cell line).
