Chemical Constituents from the Flower Buds of Panax ginseng C. A. Mey.

目的:对人参(Panax ginseng C.A.Mey.)花蕾的化学成分进行研究。方法:采用多种柱色谱技术进行分离纯化,并通过波谱分析方法鉴定化合物的结构。结果:分离鉴定了9个化合物,分别鉴定为咖啡碱(1)、胡萝卜苷(2)、豆甾醇3-O-葡萄糖苷(3)、α-菠甾醇(4)、7-豆甾烯-3β-醇(5)、人参皂苷Rk3(6)、人参皂苷Re(7)、人参皂苷Rg2(8)、谷甾醇(9)结论:其中化合物1为五加科植物中首次分离得到,化合物3、4、5为人参花中首次分离得到。

Objective： To study the chemical constituents from the flower buds of Panax ginseng C. A. Mey. Methods： Compounds were isolated and purified by various chromatographic techniques, and their structures were identified by spectral analysis. Results： Nine compounds were isolated and identified, in- eluding caffeine （ 1 ）, aucosterol （ 2 ）, stigmasterol-3-O-glucopyranoside （ 3 ）, α-spinasterol （ 4 ）, stigmast- 7-en-3β-o1（5）, ginsenoside Rk3 （6）, ginsenoside Re （ 7 ）, ginsenoside Rg2 （ 8 ）, and β-sitosterol （ 9 ）. Conclusion ： Compound 1 is isolated from the family of Araliaceae for the first time, and compound 3, 4, and 5 are firstly reported in the flower buds of Panax ginseng C. A. Mey.
