Abstract: A new steryl ester with a polyhydroxylated ergostane-type nucleus , 3β, 5α-dihydroxy - (22 E , 24 R ) -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) .

Key words: Astraeus hygrometricus
