Detection was carried out at 230 nm.Different validation parameters such as specificity,sensitivity, linearity, accuracy, precision, ruggedness and robustnesswere performed.Outcome: Optimizedchromatographic conditions were achieved and results showed good peakresolution between quercetin and rutin. The retention time was found at 7.4 minand 2.8 min. The LOD for quercetin and rutin was found to be 10 ng and 15 ng& LOQ was found to be 90 ng and 100 ng. The calibration curve was fixed at0-100000 ng/ml. With change in analytical method parameters, analyst,laboratory conditions did not affect the results. % CV was calculated for allthe parameters and found to be within specification limits. The developedmethod can be used for the quantitative and qualitative estimation of quercetinand rutin for the herbal medicinal products.Keywords: Herbal medicinal products,ICH, Quercetin, Rutin, UFLC %K Herbal medicinal products %K ICH %K Quercetin %K Rutin %K UFLC %U http://www.hygeiajournal.com/Downloads/57650957115.priyanka%20final%20Corrected%20manuscript.pdf
