Five steroles were isolated from the sclerotium of Polyporus umbellatus FRIES (Polyporaceae) and identified as (22E)-ergosta-5,7,9(11),22-tetraen-3β-ol (1),ergosta-5,7-dien-dien-3β-ol (2), ergost-7-en-3β-ol (3),(22E)-ergosta-6,8(14),22-trien-3β-ol (4),and (22E)-ergosta-8(14),22-dien-3β-ol (5).Their structures were determined on the basis of spectral data.Compounds 1-5 have been isolated from the sclerotium of P.umbellatus for the first time.
