Determination of Salicylic Acid, Resorcinol and Chloramphenicol in Junlieping Tincture by Reversed-Phase High Performance Liquid Chromatography
反相高效液相色谱法测定皲裂平酊剂中水杨酸、间苯二酚、氯霉素的含量

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.
