Six triterpenes including three new from extracts of sclerotium of Inonotus obliquus and four compounds from extracts of cultured mycelia have been isolated. They were lanosterol (1), inotodiol (2), trametenolic acid (3), 3b-hydroxy-8,24-dien-lanosta-21,23-lactone (4), 21,24-cyclopentalanosta-3b,21,25-triol-8-ene (5), 3b,22,25-trihydroxy-lanosta-8-ene (6) from the sclerotium and lanosterol (1), ergosterol (7), ergosterol peroxide (8), glucositol (9), 3b,22-dihydroxy-lanosta-7,9(11),24-triene (10), and 5-(2ў-etene-6ў,6ў-dimethyl-cyclohexa)- 3-methyl-pentanol (11) from the cultured mycelia. The biogenetic relationship of those compounds is discussed in detail.
