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。
Objective To study the chemical composition of crabs Methods The compounds were isolated and purified by repeated silica gel column chromatography, Sephadex LH-20 column chromatography and recrystallization. Their chemical structures were identified by spectral analysis. Results Eight compounds were isolated from the cortex of the yellow croaker and identified as myoinositol (1), lupeol (2), 3-acetoxyoleanolic acid (3) 16-β-hydroxylupane-20 (29) -en-3-one, 4), 1’-O-β-D- 3,4-dihydroxyphenethyl) -6’-O-vanillyl-glucopyranoside ([1’-O-β-D-3,4-dihydroxyphenyl) ], 5), daucosterol (6), oleanolic acid (7), n-butyl-β-D-fructopyranoside (8) Conclusion Compounds 1, 3 and 8 were isolated from wild papaya for the first time. Compounds 2 and 4 were isolated from yellow berries for the first time.
