摘要
目的 :研究苦玄参的化学成分 ,为更好地开发利用苦玄参作基础。方法 :采用色谱技术进行分离 ,以波谱等方法确定化合物的结构。结果 :从苦玄参乙醇提取物的较低极性部位中分离鉴定了 6个化合物 ,即N ben zoylphenylalanyl L phenylalaninolacetate(1) ,1 羟基 7 羟甲基蒽醌 (2 ) ,9,16 二羰基 10 ,12 ,14 三烯 十八碳酸 (3) ,5 ,7,4′ 三羟基黄酮 (4) ,β 谷甾醇 (5 )和胡萝卜苷 (6 )。 结论 :化合物 1～ 6均为首次从苦玄参中分离得到。化合物 1～ 3的13 C NMR数据为首次提供。
Objective: To isolate and identify compounds from Picria fel-tarrae in order to utilize it better. Method: Constituents from Picria fel-tarrae were isolated by several column chromatography and their structures were elucidated on the basis of chemical and spectral analysis. Result: Six compounds,N-benzoylphenylalanyl-L-phenylalaninol acetate (1),1-hydroxy -7- hydroxymethyl-9,10-anthraquinone (2),9,16-dioxo-10,12,14-octadeca-trienoic acid (3),5,7,4′-trihydroxy-flavone (4),β-sitosterol (5),and daucosterol (6) were obtained from the fraction with relatively low polarity of EtOH extract of Picria fel-tarrae . Conclusion: Compounds 1-6 were isolated from picria fel-tarrae Lour for the first time,and the 13 C-NMR data of compounds 1-3 are provided firstly in the literature.
