Development and validation of new analytical method for the simultaneous estimation of daunorubicin and cytarabine in bulk and pharmaceutical dosage form
A simple, Accurate, precise method was developed for the simultaneous estimation of the Daunorubicin and Cytarabine inhalation dosage form. Chromatogram was run through BDS C18 150 x 4.6 mm, 5m. Mobile phase containing 0.1% OPA: Acetonitrile taken in the ratio 60:40 was pumped through column at a flow rate of 1.0 ml/min. Temperature was maintained at 30°C. Optimized wavelength selected was 240nm. Retention time of Daunorubicin and Cytarabine were found to be 2.245 min and 2.813. %RSD of the Daunorubicin and Cytarabine were and found to be 0.6and 0.3 respectively. %Recovery was obtained as 99.39% and 99.26% for Daunorubicin and Cytarabine respectively. LOD, LOQ values obtained from regression equations of Daunorubicin and Cytarabine were 0.03, 0.10 and 0.31, 0.94 respectively. Regression equation of Daunorubicin is y = 2677x + 703.5, y = 2524x + 104.7 of Cytarabine.Retention times were decreased and that run time was decreased, so the method developed was simple and economical that can be adopted in regular Quality control test in Industries.
