麻黄碱与伪麻黄碱是麻黄的主要有效成分,也是一对化学物理性质相似的差向异构体。二者的结构只是构象不同,用色谱方法分离有一定难度。本文成功地引入共轭方向在μBordapak C_(18)色谱柱上对流动相组成进行
Ephedrine and pseudoephedrine are the main active ingredients of ephedra and are also epimers with similar chemical and physical properties. The structure of the two is only a conformational difference, with chromatographic separation of a certain degree of difficulty. This paper successfully introduced the conjugate direction on the μBordapak C_ (18) column on the mobile phase composition
