摘要
目的:研究藏药宽筋藤的化学成分。方法:采用硅胶柱色谱、薄层色谱和制备高效液相色谱等分离纯化技术,结合波谱方法分离鉴定化合物结构。结果:从宽筋藤中分离纯化得到12个化合物,分别鉴定为:齐墩果酸(1)、熊果酸(2)、没食子酸(3)、对羟基苯甲酸(4)、异鼠李素(5)、p-香豆酰-多巴胺(6)、二十四烷酸(7)、二十八烷醇(8)、十九烷醇(9)、十八烷酸(10)、β-谷甾醇(11)、胡萝卜苷(12)。结论:其中,化合物1~10为首次从该植物中分离得到。
Objective: To study the chemical constituents from Tinospora sinensis. Methods:Column chromatography techniques were used for compounds separation, their structures were elucidated by means of spectral analysis. Results : Twelve compounds were iso- lated from Tinospora sinensis, their structures were identified as oleanic acid ( 1 ), ursolic acid (2), gallic acid(3) ,4-hydroxybenzoic acid (4), isorhamnetin (5) ,p-coumaroyldopamine (6) , lignoceric acid ( 7 ), octacosanol ( 8 ), nonadecanol ( 9 ), stearic acid ( 10 ) ,β-sitosterol (11 ) ,daucosterol(12). Conclusion:Compounds 1 -10 are isolated from this plant for the first time.
