黄腊果藤茎化学成分的分离与鉴定

目的研究黄腊果藤茎的化学成分。方法采用反复硅胶柱色谱法、Sephadex LH-20柱色谱法和重结晶等进行分离纯化,并通过波谱分析技术鉴定其化学结构。结果从黄腊果藤茎中分离得到8个化合物,分别鉴定为肌醇(myoinositol,1)、羽扇豆醇(lupeol,2)、3-乙酰齐墩果酸(3-acetoxyoleanolic acid,3)、16-β-羟基羽扇豆烷-20(29)-烯-3-酮(16-β-hydroxylupane-20(29)-en-3-one,4)、1'-O-β-D-(3,4-二羟基苯乙基)-6'-O-香草酰基-葡萄苷(1'-O-β-D-(3,4-dihydroxyphenyl)-ethyl-6'-O-vanilloyl-glucopyranoside],5)、胡萝卜苷(daucosterol,6)、齐墩果酸(oleanolic acid,7)、正丁基-β-D-吡喃果糖苷(n-butyl-β-D-fructopyranoside,8)。结论化合物1、3、8为首次从野木瓜属植物中分离得到,化合物2、4～7为首次从黄腊果中分离得到。

Isolation and identification of chemical constituents from stems of Stauntonia brachyanthera Hand.-Mazz.

Objective To study the chemical constituents of stems of Stauntonia brachyanthera Hand.-Mazz..Methods The compounds were isolated by chromatography on silica gel column,Sephadex LH-20 column and recrystallization method,and their structures were determined on the basis of special analysis.Results Eight compounds were obtained and identified as myoinositol(1),lupeol(2),3-acetoxy oleanolic acid(3),16-β-hydroxylupane-20(29)-en-3-one(4),1-O-β-D(3,4-dihydroxyphenyl)-ethyl-6-O-vanilloyl-glucopyranoside](5),daucosterol(6),oleanolic acid(7),n-butyl-β-D-fructopyranoside(8).Conclusions Compounds 1,3 and 8 are isolated from this genus firstly,while compounds 2,4-7 are isolated from this herb for the first time.
