【Abstract】 Twelve steroids, including eight ergostane_type sterols and four mono_glucosides of ergostane_type sterols, were isolated from the ethyl acetate soluble fraction of the fungus Pleurotus ostreatus （Jacq.:Fr.） Kummer. A new compound 3_Oβ D _glucopyranosyl₂2 E , 24 R _ergosta₇, 22_diene₅α, 6β, 9α_triol, was structurally elucidated by spectroscopic and chemical methods. The eleven known compounds were 22 E , 24 R _ergosta₇, 22_diene₃β, 5α, 6β, 9α_tetraol; 3_Oβ D _glucopyranosyl₂2 E , 24 R _ergosta₇, 22_diene₅α, 6β_diol; 22 E , 24 R _ergosta₇, 22_diene₃β, 5α, 6β_triol; 22 E , 24 R _ergosta₅, 7, 22_trien₃β_ol 3_Oβ D _glucopyranoside; ergosterol; 22 E , 24 R _ergosta₇, 22_dien₃β_ol 3_Oβ D _glucopyranoside; 22 E , 24 R _ergosta₇, 22_diene₃β_ol; 22 E , 24 R _ergosta₄, 6, 8, 22_tetraen_3one; 22 E , 24 R _ergosta₇, 22_diene₃β, 5α, 6α_triol; ergosterol peroxide; 22 E , 24 R _ergosta₇, 22_diene₃β, 5α_diol_6one.更多还原
