Abstract
Twelve lanostane triterpenoids (1-12) including a new one 16α,26-dihydroxylanosta-8,24-dien-3-one (1) were isolated from the fruiting bodies of Ganoderma hainanense. The structure of the new compound was elucidated by 1D and 2D NMR and MS spectroscopic analyses. All isolates were evaluated for their cytotoxicities against human tumor cell lines K-562, SMMC-7721, and SGC-7901 and five compounds (1, 2, 5,7, and 9) showed definite cytotoxicities against K-562 cell line. Meanwhile, compounds 2, 5,7, and 9 exhibited cytotoxic activities against SMMC-7721 and SGC-7901 cell lines.
