钟花报春花的化学成分研究(Ⅱ)

Chemical Constituents of Primula sikkmensis Hook(Ⅱ)

从钟花报春花Primula sikkmensis Hook.中分离得到5个化合物,通过波谱分析其结构分别鉴定为5-羟基黄酮(1),2-苯基色原酮(2),5,8-二羟基黄酮(3),2'-羟基黄酮(4),3'-羟基-黄酮-4'-O-β-D-吡喃葡萄糖苷(5)。其中化合物1～4首次从该属植物中分离得到,化合物5首次从该植物中分离得到,并首次对3的NMR数据进行了归属。

Five known compounds were isolated from the Spend of Primula sikkmensis Hook. Their structures were elucidated as following based on spectral method ： 5-hydroxy flavone （ 1 ）, 2-phenyl-chromone （ 2 ）, 5,8-dihydroxy flavone （3）, 2＇-hydroxy flavone （4）, 3 ＇-hydroxy-flavone-4＇-O-β-D-glucopyranoside （5）, respectively. Compound 5 was isolated from this plant and compound 14 were isolated from genus Primula for the first time. The 1 H and 13C NMR data of comround 3 were assigned for the first time.
