A new steryl ester with a polyhydroxylated ergostane-type nucleus, 3β, 5α-dihydroxy-(22E, 24R)-ergosta-7, 22-dien-6α-yl palmitate (1), together with three known compounds (2-4) was isolated from the culture mycelia of the basidiomycete Astraeus hygrometricus. The structure of compound 1 was elucidated on the basis of extensive spectroscopic methods (IR, HR-FAB-MS, 1D and 2D NMR).
