| 摘 要： | 建立了高速逆流色谱(HsCCC)分离制备高纯度的桑枝酚类成分的新方法.分离条件如下:溶剂系统为正己烷-乙酸乙酯-甲醇冰(1∶1∶1∶2,v/v),上相为固定相,下相为流动相；流速2.0 mL/min；转速900rpm；进样量75 mg.收集得到三个高纯度化合物,经HPLC、MS、1H和13C NMR等分别鉴定为反式氧化白藜芦醇(25.2mg),反式白藜芦醇(7.4 mg)和桑辛素M(29.1 mg).高速逆流色谱可以高效分离桑枝成分,方法简便,技术可行,优于传统的柱色谱法.

| Abstract: | A new method was developed for the separation and purification of phenols by high-speed counter-current chromatography(HSCCC) from extract of Ramulus mori.The separation condition was determined as follows:n-hexane:ethyl acetate:methyl:water(1∶ 1∶ 1∶ 2,v/v) as the solvent system,the upper phase as the stationary phase,the lower phase as the mobile phase,2.0 mL/min of flow-rate,900 rpm of rotation speed,and 75 mg of injection amout.Trans-oxyresveratrol(25.2 mg),trans-resveratrol(7.4 mg),and moracin M(29.1 mg) were obtained and identified by HPLC,MS,1H and 13C NMR.It indicated that HSCCC can be used for separating the active compounds of Ramulus mori efficiently and exhibited many advantages compared with the column chromatography method. |
