[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 herein III and IV. Their chemical structures were determined as 6-methyl-2,5-dihydroxymethyl-gamma-pyranone (III) and 2-hydroxymethyl-5-alpha-hydroxy-ethyl-gamma-pyranone (IV). The others are 4-chloro-3,5-dimethoxybenzoic-O-arabitol ester, 4-chloro-3,5-dimethoxybenzoic methyl ester and 4-chloro-3,5-dimethoxybenzoic acid. In addition, a mixture of palmic and stearic acid, a mixture of behenic acid and tetracosanic acid and a mixture of 5 alpha-ergostan-3-one, 5 alpha-stigmasten-22-en-3-one and 5 alpha-stigmastan-3-one were also isolated.
