Simultaneous Estimation of Berberine and Quercetin in Pathydi Kada Formulation by Hptlc

A sensitive, selective and precise thin-layer chromatographic method has been developed and validated for the analysis of Berberine and Quercetin in Pathydi Kada laboratory prepared and Market formulation. Separation and quantification were achieved by TLC using mobile phase of Ethyl acetate: Methanol: Glacial acetic acid (6: 4: 0.5) v/v/v (Rf 0.2 & 0.84 for Berberine and Quercetin respectively) on precoated silica gel 60F254 aluminum plates and determination was carried out at 254 and 366 nm for berberine and quercetin respectively. The calibration curve was linear in the concentration range of 4-12 μg spot-1. The method was validated for precision, repeatability and accuracy. The proposed method was found to be simple, precise, specific, sensitive and accurate for the quantification of Berberine and Quercetin. This is the first TLC report for the simultaneous estimation of Berberine and Quercetin in Pathydi Kada formulation and may be useful for the routine quality control
