From the lipophilic fraction of fresh Polyporus dispansus, three new farnesylphenols (III, IV, V) and a new isopentenyphenol (VII)were isolated along with grifolin (II), O-methylgrifolin (I) and grifolic acid (VI). The structures of these new compounds were elucidated as shown in formulas III, IV, V and VII, respectively, on the basis of spectral and chemical evidence. Grifolin (II) and neogrifolin (VIII) were also isolated from P. confluens.
