摘要
目的:研究东方栓菌的化学成分。方法:通过凝胶、硅胶等多种柱层析方法分离纯化东方栓菌中的主要单体化合物,利用现代波谱分析方法及化学方法鉴定其化学结构。结果:从东方栓菌乙酸乙酯提取物中分离鉴定了12个化合物,分别鉴定为:多孔菌酸C(1)、齿孔酸(2)、茯苓酸(3)、硫磺菌酸(4)、齿孔醇(5)、麦角甾醇(6)、3β-羟基-5α,8α-过氧麦角甾醇-6,22-双烯(7)、3β-羟基-5α,8α-过氧麦角甾醇-6,9,22-三烯(8)、麦角甾-7,22-二烯-3β,5α,6β-三醇(9)、麦角甾-7,22-二烯-6β-甲氧基-3β,5α-二醇(10)、麦角甾-7,22-二烯-3β-醇(11)、亚油酸(12)。结论:其中,化合物1~5为首次从东方栓菌中分离得到。
Objective:To investigate the chemical constituents of Trametes orientalis.Methods:The major monomer compounds were isolated and purified by Sephadex LH-20,silica gel column chromatography,modern spectral analysis and chemical methods were used to identify the chemical structures.Results:Twelve compounds from the ethyl acetate extracts of Trametes orientalis were isolated and identified as polyporenic acid C(1),eburicoic acid(2),pachymic acid(3),sulfur bacteria acid(4),eburicol(5),ergosterol(6),3β-hydroxy-5α,8α-epidioxyergosta-6,22-diene(7),3β-hydroxy-5α,8α-epidioxyergosta-6,9,22-triene(8),ergosta-7,22-diene-3β,5α,6β-triol(9),ergosta-7,22-diene-6β-methoxyl-3β,5α-diol(10),ergosta-7,22-diene-3β-ol(11),linoleic acid(12).Conclusion:Compounds 1 to 5 are isolated from Trametes orientalis for the first time.
