Quality control method of policresulen suppository and policresulen suppository composition

The invention relates to a quality control method of a policresulen suppository and a policresulen suppository composition. Specifically, the invention relates to a method for controlling the quality of a policresulen suppository. According to the method, high performance liquid chromatography (HPLC) is used to measure the contents of m-cresol-4-sulfonic acid, m-cresol-6-sulfonic acid, and m-cresol-4,6-disulfonic acid of a policresulen suppository. The method also comprises a step of using HPLC to measure the content of policresulen dimer in the policresulen suppository. The invention also relates to a policresulen suppository composition. The provided quality control method can effectively control the product quality, and prepared policresulen suppository has excellent properties.
