The invention belongs to the technical field of medicines, and particularly relates to a detection method of policresulen. The content of m-cresol-4, 6-disulfonic acid, m-cresol-4-sulfonic acid, polysulfonic acid, m-cresol-6-sulfonic acid, dimercaptolphonic acid and m-cresol in the policresulen is measured by adopting a high performance liquid chromatography. The detection method can avoid the defects of the prior art, ensures the good detection and effective separation of impurities, has good system applicability and durability, can improve the passing rate of methodology verification to a certain extent, and can be used for quantifying each component in a product and releasing the product. |
