摘要
目的研究民族药岩白菜(Bergenia pururascens)的化学成分。方法利用硅胶、凝胶等色谱技术对岩白菜块根的甲醇提取物进行分离纯化,利用波谱学阐明结构。结果从岩白菜块根中分离得到9个单体化合物,分别鉴定为岩白菜素(Bergenin,1)、齐墩果酸(Oleanicacid,2)、熊果苷(Arbutin,3)、阿夫儿茶精(Afzelechin,4)、11-O-没食子酰岩白菜素(11-O-galloyl bergenin,5)、没食子酸(Gallic acid,6)、Breynioside A(7)、Diethyl disulfoxide(8)、(+)-儿茶素((+)-Catechin,9)。结论化合物4、7、8首次从该种植物中分离得到,化合物8为首次从该属植物中分离得到的含硫化合物。
Objective To investigate the chemical constituents of Bergenia pururascens. Methods The powered tuber were extracted with MeOH and purified by silica gel and Sephadex LH-20 column chromatograph. The chemical structures were elucidated on the basis of spectral analysis and physico-chemical evidence. Results Nine compounds were obtained from Bergenia pururascens, they are characterized as Bergenin （ 1 ）, Oleanic acid （2）, Arbutin （3）, Afzelechin （4）, 11-O-galloyl bergenin （5）, Gallic acid （6）, Breynioside A （7）, Diethyl disulfoxide （8）and （＋）-Catechin （9）. Conclusion Compounds 4, 7, 8 were obetained for the first time from Bergenia pururascens.
