Application of preparative high performance liquid chromatography in the study on impurities of drugs

Preparative high performance liquid chromatography(HPLC) is a way to use high-pressure,large flow of liquid delivery system for high-purity separation of the sample on high-resolution,large internal diameter,high capacity separation column.Application of the method for the separation of products in terms of purity,recovery,separation efficiency is far superior to the traditional method of preparation,and it is widely used in drug research and production fields.The efficient preparative HPLC steps,the preparative HPLC research and development direction,and the research on drug impurities in practical applications have been summarized.This article describes the research profile,characteristics of preparative HPLC,and factors that influence the process of separation and purification,steps to develop and establish the method,as well as the application of preparative HPLC in the study on impurities of drugs.Finally,the existing problems of the present preparative HPLC and the developing trend have also been discussed.
