ABSTRACT:
The prime aim of the current work is to develop and validate a novel, specific, sensitive, precise, rapid and faster isocratic elution, RP HPLC method for estimation of Divalproex in bulk and pharmaceutical dosage forms. Chromatographic separation was achieved on Agilent SB C18, (50 x 4.6 mm, 5m) using an isocratic mode with mobile phase composed of Buffer and Acetonotrile are taken in 60:40%v/v(PH 4) The flow rate was 1.0ml/min, temperature is maintained at30OC and detection was made at 210 nm. The run time was 8 min. The developed method was validated according to the ICH guide lines and different analytical parameters such as linearity, precision, accuracy, specificity, limit of detection, limit of quantitation were determined. The linearity of calibration curve for each analyte is in concentration range of 25 – 150ppm. There exists good correlation between peak area and analyte concentration. Relative standard deviation values for Divaprolex is 1.24. LOD for drug is 2.3 and LOQ is 9.4. Hence the proposed method is highly sensitive, precise, accurate, robust and fast. The short retention time allows the analysis of large number of samples in short period of time and it is cost effective, so it can be successfully applied for routine analysis of active pharmaceutical ingredient and related impurities in bulk and pharmaceutical dosage forms.
