[Determination of salicylic acid, resorcinol and chloramphenicol in junlieping tincture by reversed-phase high performance liquid chromatography].

Huiyun Zeng, Genlin Sun, Cen Li

Abstract

A reversed-phase high performance liquid chromatographic method was developed for the quantitative determination of salicylic acid, resorcinol and chloramphenicol in Junlieping tincture. The operation was carried out on an ODS column with the mobile phase of a mixture of acetonitrile-methanol-water(25:10:65, volume proportion). The eluate was detected at 278 nm wavelength. This method is simple, fast and can be used for the quality control of Junlieping tincture.
