The sterol composition of macromycete fungus Laetiporus sulphureus was analyzed by GC-MS. The fungus contained mainly C16 to C20 fatty acids, C16 to C24 fatty acid ethyl esters, and C28, C29, and C30, Δ5, Δ7, and Δ5,7 conventional sterols, and in minor amounts Δ0 analogues with saturated and unsaturated side chains. Moreover, ergosterol peroxide and cerevisterol were identified. This sterol pattern was compared with those of other members of the family Polyporaceae reported in the literature.
