摘要

A method has been established for separation of nisoldipine and impurities, for example reactants, products of side-reactions, and photodegradation products, by HPTLC on LiChrospher Si 60 F254s plates with detection at 280 nm. The mobile phase, cyclohexane–ethyl acetate–toluene, 7.5:7.5:10 (v/v), enables acceptable resolution of nisoldipine, in large excess, and possible impurities. Regression coefficients (r ≥ 0.997), recovery (98–108%), and determination limit (0.02–0.2%) were validated and found to be satisfactory. The method is convenient for quantitative analysis and purity control of nisoldipine in its raw material and dosage forms.
