摘　　要：目的:研究山菅兰色酮与芳香族类化学成分。方法:应用正相硅胶、小孔树脂、葡聚糖凝胶Sephadex LH-20、反相ODS、以及制备型高效液相等色谱法对山菅兰的化学成分进行了分离纯化;并通过理化性质及过1H-NMR、13C-NMR等波谱技术对化合物的结构进行鉴定。结果:从山菅兰乙酸乙酯层中共分离了12个化合物,分别为甲基丁香色原酮(1)、异甲基丁香色原酮(2)、5-羟基-2,7-二甲基色酮(3)、5,7-二羟基-2,6,8-三甲基色酮(4)、5,7-二羟基-2,8-二甲基色酮(5)、3-甲氧基-4-羟基苯甲酸甲酯(6)、原儿茶酸甲酯(7)、7-乙酰基-4,8-二羟基-6-甲基-1-四氢萘酮(8)、β-邻二酚羧酸甲酯(9)、2,4-二羟基-6-甲氧基-3-甲基-苯乙酮(10)、3,5-二羟基-4-甲氧基-苯甲酸甲酯(11)与吲哚-3-甲醛(12)。结论:分离得到的化合物类型,其中化合物1-5为色酮类,化合物6-12为芳香族类化合物,可为山菅兰的色酮与芳香族类成分分析提供一定的科学依据。Objective:To study the Chromones and aromatics from ethyl acetate fraction in Dianella ensifolia(L.)DC.Methods:The methanol extract was isolated by Sephadex LH-20,ODS and silica gel,coupled with the semi-preparative HPLC,to isolate the chemical constituents.The isolated compounds were identified according to their MS,1H-NMR and 13C-NMR data.Results:Eleven compounds were isolated from EtOAc extract of the edible part of Dianella ensifolia.Their structures were identified as eugenitin(1),iso eugenitin(2),5-hydroxy-2,7-dimethylchromone(3),5,7-dihydroxy-2,6,8-trimethylchromone(4),5,7-dihydroxy-2,8-dimethylchromone(5),3-methoxy-4-hydroxybenzoate(6),methyl 3,4-dihydroxybenzoate(7),7-acetyl-4R,8-dihydroxy-6-methyl-1-tetralone(8),β-orcinol carboxylate(9),2,4-dihydroxy-6-methoxy-3-methy-l acetophenone(10),methyl 3,5-dihydroxy-4-methoxybenzoate(11)and indole-3-carbaldehyde(12).Conclusion:Compounds 1-5 belong to the chromones,while compounds 6-12 are aromatic compounds.This provides a scientific basis for the analysis of chromones and aromatics components in Dianella ensifolia.
