目的研究胡蔓藤(Gelsemium elegans Benth.)中的化学成分。方法采用硅胶柱色谱和ODS柱色谱进行分离,Sephadex LH-20及制备液相进行纯化,根据理化性质和光谱分析进行结构鉴定。结果分离鉴定了8个化合物,分别为(+)-8-hydroxypinoresinol(1)、cleomiscosin C(2)、cleomiscosinA(3)、3,4-二羟基苯甲醛(3,4-dihydroxyphenyl aldehyde,4)、咖啡酸(caffeic acid,5)、1-O-咖啡酰基奎宁酸(1-O-caffeoylquinic acid,6)、4-O-咖啡酰基奎宁酸(4-O-caffeoylquinic acid,7)、1-O-咖啡酰基奎宁酸甲酯(1-O-caffeoylquinic acid methyl ester,8)。结论化合物1-8为首次从该属植物中分离得到。
Objective To study the chemical composition of Gelsemium elegans Benth. Methods The compounds were isolated by silica gel column chromatography and ODS column chromatography. Sephadex LH-20 and its preparative liquid phase were purified and identified by physicochemical properties and spectral analysis. RESULTS: Eight compounds were isolated and identified as (+) - 8-hydroxypinoresinol (1), cleomiscosin C (2), cleomiscosin A (3), 3,4-dihydroxyphenyl aldehyde Caffeic acid (5), 1-O-caffeoylquinic acid (6), 4-O-caffeoylquinic acid 1-O-caffeoylquinic acid methyl ester (8). Conclusion Compounds 1-8 were isolated from this genus for the first time.
