A Simple Reverse Phase Ultra Performance Liquid Chromatography Validated Method for Concurrent Estimation of Daunorubicin and Cytarabine in Drug Substances and Drug Product

A fast, precise, accurate, and steadiness indicating isocratic liquid chromatographic technique was created for the synchronous assurance of the daunorubicin and cytarabine in bulk and formulation. To optimize a column CHS C18 100 × 2.1 mm, 1.8 μm, mobile phase, including buffer 0.1% orthophosphoric acid, acetonitrile pick in the proportion 70:30 v/v, was pumped through the column at a flow rate of 0.3 mL/min at 240 nm, initiate to be an efficient method for elution of drug with good peak shapes, as well as, retention times. The retention time of daunorubicin and cytarabine were initiated to be 0.556 and 0.743 minutes. The % recovery was got at 100.07 and 99.88% for daunorubicin and cytarabine separately. The limit of detection (LoD) and limit of quantitation (LoQ) values got from the relapse formula of daunorubicin and cytarabine were 0.16, 0.5, and 0.64, 1.93, correspondingly. The relapse equation of daunorubicin is y = 2974.3x + 648.32, and y = 4896.5x + 4851.5 of cytarabine.
