Abstract:
Objective: Study on the chemical constituents in the ethyl acetate phase extracted from the fruiting bodies of Amauroderma rude. Methods: Silica gel column chromatography, Sephadex LH-20 gel and liquid chromatography were used to separate and purify the chemical constituents in fruiting bodies of Amauroderma rude. The compounds were identified according to their physical and chemical properties and spectroscopic data. Results: Three compounds including one new lignan and two known sterols were isolated from the ethyl acetate phase of this fungus. Their structures were identified as 3,4-dihydroxyphenacyl acetyl ketone (1), (22E, 24R)-3β,5α-dihydrox-yerogosta-7,22-diene-6-one (2), and (22E,24R)-ergosta-6,9,22-trien-3β,5α,8α-triol (3). Conclusion: Compound 1 was a new lignan and named amaurolignan B.
