摘要
目的对龙胆的化学成分进行研究。方法采用硅胶柱色谱、凝胶柱色谱进行分离 ,通过理化和波谱分析方法鉴定化合物结构。结果从乙酸乙酯层分离得到 6个化合物 ,分别为 :山奈酚(kaempferol,Ⅰ )、L 芝麻脂素 (L sesamin ,Ⅱ )、水杨酸 (salicylicacid ,Ⅲ )、阿魏酸 (ferulicacid ,Ⅳ )、齐墩果酸 (oleanolicacid ,V)、pranferin(Ⅵ )。其中化合物Ⅵ为本属中首次发现。
Objective To study the chemical constituents of Gentiana scabra Bge.Methods Six compounds were isolated by the silica gel and sephadex LH-20 column chromatography,and identified by the physico-chemical characters and many kinds of spectroscopic analyses.Results Six compounds were isolated from the EtOAc extract of Gentiana scabra Bge.They are separately kaempferol,L-sesamin,salicylic acid,ferulic acid,oleanolic acid and pranferin.Conclusion Among them, pranferin is separated from Gentiana for the first time.
