仔榄树的化学成分

摘要

采用硅胶柱层析、ODS和Sephadex LH-20等色谱技术,从仔榄树叶体积分数为95％乙醇提取物的正丁醇萃取部位分离得到11个化合物；通过理化性质和波谱数据分析,鉴定它们的结构分别为(±)-赤-3-甲氧基-4-羟基苯基丙三醇(1)、(±)-苏-3-甲氧基-4-羟基苯基丙三醇(2)、(+)-syringaresinol-4,4'-O-bis-β-D-glucopyranoside (3)、1,3,5-三甲氧基苯(4)、丁香酸葡萄糖苷(5)、2,6-二甲氧基-4-羟基-1-O-β-D-吡喃葡萄糖苷(6)、3,5-二甲氧基-苄醇-4-O-β-D-吡喃葡萄糖苷(7)、(2E,6S)-8-(α-L-arabinopyranosyl-(1”fwdarw6’)-β-D-glucopyranosyloxy)-2,6-dimethyloct-2-eno-1,2”-lactone (8)、山奈酚-3-O-β-D-吡喃葡萄糖苷(9)、2-甲胺基苯甲酸(10)、D-1-O-methyl-myo-inositol(11).化合物1～11均为首次从该植物中分离得到.%The chemical constituents of 95 % ethanolic extract of Hunteria zeylanica were separated and purified by various column chromatographies including silica gel, ODS and Sephadex LH-20 column chromatographies to obtain 11 compounds. On the basis of their physico-chemical properties and spectro-scopic data, the compounds were identified as ( ± ) -erythro-guaiacylglycerol (1) , ( ± ) -threo-guaiacylg-lycerol (2) , ( + )-syringaresinol-4,4'-O-bis-β-D-glucopyranoside (3), 1,3,5-trimethoxybenzene (4), glucosyringic acid (5) 2,6-dimethoxy-4-hydroxyphenol-l-O-β-D-glucopyranoside (6), 3 ,5-dimethoxy-benzyl alcohol 4-O-β-D-glucopyranos-ide (7), (2E,6S)-8-(α-L-arabinopyranosyl-( l"fwdarw6')-β-D-glucopyranosyloxy)-2,6-dimethyloet-2-eno-l, 2"-lactone (8), kaempferol-3-O-β-D-glucoside (9), 2-methylamino-benzoic acid (10), D-l -O-methyl-myo-inositol (11). All compounds were isolated from this plant for the first time.
