A new method for determination of cephalexin based on the color reaction between cephalexin and ninhydrin has been developed.

基于头孢氨所含伯氨基在酸条件下可与茚三酮发生显色反应,从而建立流动注射光光度法测定头孢氨的新方法。

To provide proof of grafting, modified hydrolysate was identified by indanthrone, the IR and amino acid composition analysis of hydrolysate and modified hydrolysate were studied.
