RESUMO
AIM To study the chemical constituents from the fruiting bodies of Abortiporus biennis (Bull.) Singer.METHODS The ethyl acetate fraction of methanol extract from A.biennis fruiting bodies was isolated and purified by silica,Sephadex LH-20 and RP-18 column,then the structures of obtained compounds were identified by spectral data.RESULTS Six compounds were isolated and identified as (22E,24R)-ergosta-5,7,22-trien-3ββ-ol (1),(22E,24R)-5α,8α-epoxyergosta-6,22-dien-3β-ol (2),cerevisterol (3),(22E,24R)-ergosta-4,6,8 (14),22-tetraen-3-one (4),1,3-dioleoyl-2-1inoleoylglycerol (5),cereboside B (6).CONCLUSION All the compounds are isolated from this fungus for the first time.
