目的对五加科五加属植物无梗五加果的化学成分进行研究。方法采用硅胶柱色谱法、Sephadex LH-20柱色谱法、ODS柱色谱法以及制备液相色谱法对无梗五加果的化学成分进行分离,根据化合物的理化性质及波谱数据鉴定其结构。结果分离得到8个已知的酚酸类化合物,分别为对羟基苯乙醇(tyrosol,1)、对羟基苯丙酸(p-hydrocoumaric acid,2)、原儿茶醛(protocatechuic aldehyde,3)、咖啡酸(caffeic acid,4)、4-(3,4-二羟基苯基)-2-丁酮[4-(3,4-dihydroxyphenyl)-2-butanone,5]、没食子酸(gallic acid,6)、对羟基苯甲酸(4-hydroxy-benzoic acid,7)、邻苯二酚(pyrocatechol8,)。结论化合物5为首次从五加科植物中分离得到,化合物2为首次从五加属植物中分离得到,化合物17、、8为从该植物中首次分离得到。
OBJECTIVE To study the chemical constituents of the stems of Pentaphicaceae in Wujiaochang. Methods Silica gel column chromatography, Sephadex LH-20 column chromatography, ODS column chromatography and preparative liquid chromatography (HPLC) were used to separate the chemical constituents of S. septempunctata. Their chemical structures were elucidated on the basis of physico-chemical properties and spectral data. Results Eight known phenolic acids were isolated and identified as tyrosol (1), p-hydrocoumaric acid (2), protocatechuic aldehyde (3), p- Caffeic acid (4), 4- (3,4-dihydroxyphenyl) -2-butanone, 5, gallic acid 6), 4-hydroxy-benzoic acid (7) and catechol (pyrocatechol8). CONCLUSION Compound 5 was isolated from the plants of the genus Gracilis for the first time. Compound 2 was isolated from genus Genus for the first time. Compounds 17 and 8 were isolated from this plant for the first time.
