方法:用硅胶柱层析法对平贝总碱进行分离纯化,固定相为薄层层析硅胶G,流动相为乙酸乙酯-甲醇-氨水(17:2:1)。
The solid phase was thin layer chromatography silica gel G and the mobile phase was ethyl acetate-methanol-ammonia ( 17:2:1 ) .

薄层层析硅胶GF254为固定相,乙酸乙酯甲醇水(7-2-1,v/v/v)为展开剂,熊果苷和氢醌的Rf值分别为0.56和0.67。
The optimal conditions of TLC were as follows : silica gel GF254 as stationary phase , ethyl actate-methanol-water ( 7-2-1 , v / v / v ) as mobile phase .
