本文用离心薄层层析法对半合成头孢菌素类化合物进行了制备量分离的研究。采用国产LBC-Ⅰ型离心薄层层析仪,在1mm厚硅胶GF(254)(10-40μ,薄层层析用)吸附层上有效地分离了7β—(6—取代-2-喹
In this paper, the preparative separation of semisynthetic cephalosporins was studied by centrifugal TLC. Using domestic LBC-Ⅰ centrifugal thin-layer chromatography, 7β- (6-substituted-2-quinoline
