仔榄树的化学成分

Chemical constituents from the leaves of Hunteria zeylanica

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-in-ositol(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-guaiacylglycerol （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-dimethoxybenzyl alcohol 4-O-β-D-glucopyranos-ide （ 7 ）, （ 2E, 6S ） -8-（ α-L-arabinopyranosyl-（1″fwdarw6′） -β-D- glucopyranosyloxy） -2,6-dimethyloct-2-eno-1,2＂-lactone （ 8 ）, kaempferol-3-O-β-D-glucoside （ 9 ）, 2- methylamino-benzoic acid （ 10）, D-1-O-methyl-myo-inositol （ 11 ）. All compounds were isolated from this plant for the first time.
