OBJECTIVE:To study the chemical constituents in the fruiting bodies of armillariella tabescens for searching active leading compounds.METHODS:Compounds were isolated from methanol extract of armillariella tabescens by chromatography column.RESULTS:Six compounds were isolated and identified as methyl oleate(1),stearic acid(2),3?-hydroxyergosta-5,7,22-triene(3),armillarisin B(4),5-hydroxy-uracil(5) and cerebroside B(6),respectively.CONCLUSION:Compounds 1,2,3,5,6 were firstly isolated from the fruiting bodies of armillariella tabescens.
