Popis: This study describes two extraction-free and direct spectrophotometric methods for the determination of Cephalexin in a pure and pharmaceutical dosage form. In this study, a zero-order method has exhibited maximum absorption max at 263 nm, while area under curve method has calculated in the range 260-266nm. The Linearity of both methods in the range (10- 60 nm), the limit of detection (LOD) is 0.808 for Zero-order method and 0.781 for the area under curve method. These methods are successfully applied to determination of Cephalexin in a pharmaceutical dosage form.
