ABSTRACT: A simple, precise reverse phase high performance liquid chromatographic (RP-HPLC) method has been developed and validated for the flavonoid quercetin, isolated from Tridax procumbens L. The method was validated by using Phenomenex C18 (250 x 4.6mm i.d) Column. A simple, cost effective mobile phase consisting of (ACN and 10 m/moL Phosphate buffer as mobile phase in proportion of 50:50 v/v ) pH 3, 1.0 ml/min Flow rate at 370nm by using UV Visible detector. The retention time of Quercetin was found to be 3.392 minutes. The Quercetin linearity range was found to be 05 to 25 μg/mL. The accuracy and precision of commercially available preparations and in-house cream formulations were investigated using a one-way ANNOVA test. The Percentage recovery of both formulations was found to be 99.83%, 99.88%, 99.82% and 98.92%, 98.18%, 98.86%. Robustness of analytical method was studied by using 2/3 full factorial design by using Design expert software. The Percentage assay and % RSD of marketed capsule and in house cream was found to be 98.38 %, 97.40% and 0.05273, 0.02053 respectively. The Limit of Quantitation and Limit of detection were found to be 0.9053μg/mL and 2.5435μg/mL respectively. The development method of quercetin is simple, accurate, precise, sensitive, and robust
