ISOLATION AND IDENTIFICATION OF TWO NEW PYRONE COMPOUNDS FROM THE CULTURE OF HERICTUM ERINACEUS

Four crystalline and one liquid compounds were isolated from the solid cultured extract of Hericium erinaceus, Two of them are new, named herierin Ⅲ and Ⅳ. Their chemical structures were determined as 6-methy 1-2,5-dihydroxymethyl-γ-pyranone (Ⅲ) and 2-hydroxymethy 1-5-a-hydroxy-ethyl-γ-pyranone (Ⅳ). The others are 4-chloro-3, 5-dimethoxybenzoic-O-arabitol ester, 4-chloro-3, 5-dimethoxybenz0ic methyl ester and 4-chloro-3,5-dimethoxybenzoic acid. In addition, a mixture of palmic and stearic acid, a mixtrue of behenic acid and tetracosanic acid and a mixture of 5α-ergostan-3-one, 5α-stigmasten-22-en-3-one and 5α-stigmastan-3-one were also isolated.
