Abstract
High performance liquid chromatography has been the most popular choice for the determination of atorvastatin. In this study, two-step isocratic chromatography on silica gel 60F254 HPTLC layer and densitometric quantitation at λ = 280 nm was developed for the separation of atorvastatin from plasma constituencies and sodium diclofenac as peak-tracer. The established HPTLC method was validated in terms of LOD/LOQ, linearity, recovery and repeatability. The calibration function of the analyte was linear in the range 101–353.5 ng zone−1 and the correlation coefficient was 0.9969. The limits of detection and quantitation were 30.3 and 101 ng zone−1. The recovery and relative standard deviation obtained from between-days analysis were 97.5–103.0 and 1.7–3.4%.
