目的研究黄腊果(Stauntonia brachyanthera Hand.-Mazz.)藤茎的化学成分。方法利用溶剂萃取法、反复硅胶柱色谱、Sephadex LH-20柱色谱、开放ODS柱色谱、制备型高效液相色谱法等各种方法进行化合物的分离纯化,并采用波谱学技术进行结构鉴定。结果从黄蜡果藤茎的体积分数为70%的乙醇提取物中分离得到6个化合物,分别鉴定为3-O-α-L-吡喃阿拉伯糖-30-去甲齐墩果烷-12,20(29)-二烯-28-羧酸(3-O-α-L-arabinopyranosy-akebonic acid,1)、cyclo-olivil-9-O-β-glucopyranoside(2)、staunoside C[(+)-1-hydroxysyringaresinol-1-β-D-glucoside](3)、ficuscarpanoside B(4)、ficuscarpanoside A(5)、2-(3,4-二羟基苯基)乙基-β-D-吡喃葡萄糖苷([2-(3,4-dihydroxyphenyl)ethyl-β-D-glucopyranoside],6)。结论化合物1-3、6为首次从野木瓜属植物中分离得到,化合物4和5为首次从黄腊果中分离得到。
Objective To study the chemical composition of cane in Stauntonia brachyanthera Hand.-Mazz. Methods The compounds were isolated and purified by solvent extraction, repeated silica gel column chromatography, Sephadex LH-20 column chromatography, open ODS column chromatography and preparative high performance liquid chromatography. Their structures were identified by spectroscopic techniques. Results Six compounds were isolated from 70% ethanolic extract of yellow waxy cane and identified as 3-O-α-L-arabinofuranosyl-30-nor-substituted oleanane- 3-O-α-L-arabinopyranosy-akebonic acid, cyclo-olivil-9-O-β-glucopyranoside (2), staunoside C [(+ -1-hydroxysyringaresinol-1-β-D-glucoside], ficuscarpanoside B (4), ficuscarpanoside A (5), 2- (3,4- dihydroxyphenyl) ethyl- [2- (3,4-dihydroxyphenyl) ethyl-β-D-glucopyranoside], 6). Conclusions Compounds 1-3 and 6 were isolated from wild papaya plants for the first time. Compounds 4 and 5 were isolated from yellow berries for the first time.
