从猴菇菌(Hericium erinaceus Bull pers)培养物中分得4个晶体和1个液态化合物。经鉴定,其中二个是新化合物,命名为猴菇菌素Ⅲ(Ⅲ)和Ⅳ(Ⅳ),其化学结构分别定为6-甲基-2,5-二羟甲基-γ-吡喃酮(Ⅲ)和2-羟甲基-5-(1′-羟基)-乙基-γ-吡喃酮(Ⅳ)。其余三个晶体的化学结构分别为4-氯-3,5-二甲氧基苯甲酸-O-阿拉伯糖醇酯(Ⅰ),4-氯-3,5-二甲氧基苯甲酸甲酯(Ⅲ),4-氯-3,5-二甲氧基苯甲酸(Ⅴ)。 Four crystals and one liquid compound were isolated from the Hericium erinaceus Bull pers culture. After identification, two of them are new compounds named as phacladin III(III) and IV(IV), whose chemical structures are defined as 6-methyl-2,5-dihydroxymethyl-γ-pyran Ketone (III) and 2-hydroxymethyl-5-(1’-hydroxy)-ethyl-γ-pyrone (IV). The chemical structures of the remaining three crystals are 4-chloro-3,5-dimethoxybenzoic acid-O-arabinitol ester (I), methyl 4-chloro-3,5-dimethoxybenzoate, respectively (III) 4-Chloro-3,5-dimethoxybenzoic acid (V).
