Two novel trinorlanostanes, cochlates A and B (1 and 2), with a 3,4-seco-9,10-seco-9,19-cyclo skeleton, as well as six new triterpenoids, fornicatins D-F (3-5) and ganodercochlearins A-C (6-8), together with five known triterpenoids (9-13), were obtained from the fruiting bodies of Ganoderma cochlear. The structural elucidation was achieved by interpretation of spectroscopic data, and compounds 2 and 7a were further characterized by X-ray crystallographic analysis. Fornicatins A, D, and F (10, 3, and 5) and fredelin (13) lowered the ALT and AST levels in HepG2 cells treated with H2O2, suggesting that they could display in vivo hepatoprotective activities.
