Spectrophotometric Determination of Cephalexin

Li Huakan (Jinzhou Medical College, Jinzhou 121001) Ma Xiaoda (Jinzhou Institute of Professional Disease, Jinzhou 121000)  
Cephalexin reacts with ninhydrin in acid medium to give a violet colour product with maximum absorption wavelength at 566 run. The optimum condition of determination was reported. The liner range of Beer's law is 0.5 - 50 mg/L. The apparent molar absorptivity is 7.93 ×103L·mol-1·cm-1 at 566 nm. The method is successfully applied to the determination of cephalexin for pharmaceutical preparation.
