真姬菇次生代谢产物化学成分研究
Study on the Chemical Constituents of the Secondary Metabolites from Hypsizygus marmoreus
【摘要】 [目的]研究真姬菇次生代谢产物的化学成分。[方法]真姬菇通过大米培养发酵、乙酸乙酯提取后,获得提取物。提取物经硅胶柱、Sephadex LH-20凝胶柱、RP-C18反相硅胶柱等分离纯化,根据波谱数据与文献对比解析化合物结构。[结果]从真姬菇大米发酵的乙酸乙酯提取物中分离得到了14个化合物,分别鉴定为羟基大黄素(1)、1,8-二羟基蒽醌(2)、大黄素(3)、大黄素甲醚(4)、1-羟基-2-甲基蒽醌(5)、2,4-二羟基苯甲酸甲酯(6)、4-羟基苯甲酸甲酯(7)、(2ALPHA)-A′-新伽马蜡烷-2,22-二醇(8)、β-谷甾醇(9)、豆甾醇(10)、麦角甾-4,6,8(14),22-四烯-3-酮(11)、麦角甾-7,22-二烯-3-酮(12)、硬脂酸(13)、油酸(14)。[结论]化合物1~14均为首次从玉蕈属真菌次生代谢产物中分离得到。
【Abstract】 [Objective] To study the chemical constituents of the secondary metabolites from Hypsizygus marmoreus. [Method]The fermented rice substrate of Hypsizygus marmoreus was extracted by using ethyl acetate, then separated and purified through silica gel, Sephadex LH-20 column and RP-C18 column. Compared with the reports, the structures of isolated compounds were identified according to spectral data. [Result]Totals of 14 compounds were isolated from the ethyl acetate extraction of Hypsizygus marmoreus, which were identified as citreorosein(1), 1,8-Dihydroxyanthraquinone(2), emodin(3), physcion(4), 1-Hydroxy-2-methylanthraquinone(5), methyl 2,4-dihydroxybenzoate(6), 4-Hydroxybenzoic acid methyl ester(7), 2-hydroxydiplopterol(8), β-Sitosterol(9), stigmasterol(10),(22E)-ergosta-4,6,8(14),22-tetraen-3-one(11), ergosta-7,22-dien-3-one(12), stearic acid(13), oleic acid(14). [Conclusion]Compounds 1-14 are isolated from the genus Hypsizygus for the first time.
