摘要

A UV visible spectroscopic method has been developed for the simultaneous estimation of quercetin and ellagic acid in a suspension. Validation of the developed method was done according to ICH Q2R2 guidelines. Calibration curves (R2 > 0.98) were prepared, demonstrating a linear response for the concentration ranges of both drugs. The results indicated high levels of accuracy and precision (all %RSD values <2%). The findings suggest that this method can be readily adopted in routine laboratory settings, facilitating the simultaneous monitoring of drug levels in both bulk and dosage forms.
