目的研究蓬莱葛(Gardneria multiflora Makino)中的单萜吲哚生物碱类成分。方法蓬莱葛全株用体积分数95%乙醇溶液加热回流提取,减压回收乙醇,浓缩液加水稀释后经石油醚、三氯甲烷萃取,得总生物碱。总生物碱利用正相硅胶、反相Rp-18、Sephadex LH-20等柱色谱方法分离纯化,通过光谱数据进行结构鉴定。结果从蓬莱葛中分离得到1个单萜吲哚型生物碱。结论从蓬莱葛中分离得到1个单萜吲哚型生物碱为一新的化合物。
Objective To study the monoterpene indole alkaloids in Gardneria multiflora Makino. Method Penglaige the whole plant volume fraction of 95% ethanol heated reflux extraction, vacuum recovery of ethanol, the concentrate diluted with water, petroleum ether, chloroform extraction, the total alkaloids. The total alkaloids were separated and purified by using normal phase silica gel, reversed-phase Rp-18 and Sephadex LH-20 column chromatography. The structures were identified by spectral data. Results A monoterpene indole alkaloid was isolated from Penglaige. Conclusion A monoterpene indole alkaloid was isolated from Penglaige and was a new compound.
