目的为进一步开发利用胡蔓藤(Gelsemium elegansBenth.)中非生物碱类化学成分提供依据。方法采用HPD-800大孔吸附树脂色谱、硅胶柱色谱和ODS中压柱色谱分离,采用葡聚糖凝胶LH-20柱色谱及制备液相纯化,根据理化性质和波谱数据鉴定结构。结果分离鉴定了7个非生物碱类化合物,分别为东莨菪内酯(scopoletin,1)、咖啡酸乙酯(caffeic acid ethyl ester,2)、肉桂酸(cin-namic acid,3)、水杨酸(salicylic acid,4)、香草酸(vanillic acid,5)、白藜芦醇(resveratrol,6)、正三十六烷醇(hexatriacontan-1-ol,7)。结论化合物2~4、6为首次从胡蔓藤属植物中分离得到。
Objective To further develop and utilize the chemical constituents of Alkaloids from Gelsemium elegans Benth. Methods HPD-800 macroporous adsorption resin, silica gel and ODS medium-pressure column chromatography were used. The compounds were purified by Sephadex LH-20 column chromatography and preparative liquid chromatography. Their structures were elucidated on the basis of physico-chemical properties and spectral data. Results Seven non-alkaloids were isolated and identified as scopoletin (1), caffeic acid ethyl ester (2), cin-namic acid (3), salicylide Salicylic acid (4), vanillic acid (5), resveratrol (6) and hexatriacontan-1-ol (7). Conclusion Compounds 2 ~ 4 and 6 were isolated from Arabidopsis for the first time.
