Abstract: Two new drimane sesquiterpenoids (1 and 2), as well as five known compounds (3-7), were isolated from the basidiomycete Trichaptum biforme. The structures of new compounds were elucidated by extensive spectroscopic methods, and the known compounds were identified by comparing their spectroscopic data with those reported in the literature. The cytotoxicities results against five human cancer cell lines of compounds 1 and 2 were negligible.
