The isolation of water extracts of larch bark was carried out by cellulose column and centrifugal thin layer chromatography with different solvents for elution. 落叶松树皮水浸提物,以纤维素粉作吸附剂,60%乙醇水作洗脱剂,进行了柱色谱的粗分与细分;
The detail is as follows. 1. An off-line centrifugal column chromatography system was installed. With this system, the band broadening of two cis-trans-isomers was obtained. 具体内容如下:1.构建了离线式离心柱色谱系统,应用该系统获得了一对顺反异构体在离心色谱柱内的谱带展宽情况。
