The fruiting body of Phellinus linteus was extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH and H₂O. The repeated silica gel and ODS column chromatographies of the EtOAc fraction led to isolation of four sterols. From the result of spectral data including NMR, MS and IR, the chemical structures of the sterols were determined as ergosta-7,24(28)-dien-3β-ol (episterol, 1), 5α,8α-epidioxyergosta-6,9(11),22-trien-3β-ol (dehydroperoxyergosterol, 2), 5α,8α-epidioxyergosta-6,22-dien-3β-ol (ergoterol peroxide, 3), and 3β,5α-dihydroxy-6β-methoxyergosta-7,22-diene (6-O-methylcerevisterol, 4).
