title: Quantitative determination of morphine in paregoric USP by high-pressure liquid chromatography.
abstract: The quantitative determination of morphine in paregoric by reversed-phase high-pressure liquid chromatography is described. The method is simple, accurate, and fast compared to the USP method. Benzoic acid in paregoric also can be determined quantitatively with the same column. The method was applied to two commercial samples with excellent results.
