应用硅胶柱色谱、Sephadex LH-20柱色谱及高效制备薄层色谱等方法对青杞中的倍半萜进行分离纯化,根据理化性质和波谱数据对其化学结构进行阐明,发现并鉴定了10个倍半萜化合物,分别为:白英醇D(1),江西白英素B(2),1,2-去氢香附酮(3),山烟草酮A(4),去氢假虎刺酮(5),齿叶囊吾醇(6),甘松醇A(7),江西白英素F(8),白英醇B(9),江西白英素D(10)。化合物1~10均为首次从青杞中发现,化合物5~7为首次从茄属植物中发现。
Silica gel column chromatography, Sephadex LH-20 column chromatography and high performance preparative thin layer chromatography and other methods of sesquiterpenoids in Qingqi were isolated and purified according to their physical and chemical properties and spectral data to elucidate its chemical structure, found and identified 10 Sesquiterpene compounds are as follows: Baiying alcohol D (1), Jiangxi Baiyin B (2), 1,2-dehydroacetone ketone (3), mountain tobacco ketone A (4) (6), Cortisone A (7), Jiangxi Baiying Su F (8), Baiying alcohol B (9), Jiangxi Baiying Su D (10). Compounds 1 to 10 were found from Qingqi for the first time, and compounds 5 to 7 were found for the first time in Solanum.
