OBJECTIVE To establish a quality standard of the external used washing powder for Hemorrhoid. METHODS The Radix Saposhnikoviae, Radix Et Rhizoma Glycyrrhizae and Pericarpium Zanthoxyli were identified by TLC and the content of berberine hydrochloride in Rhizoma Coptidis was determined by HPLC. RESULTS Radix Saposhnikoviae, Radix Glycytthizae and Pericarpium Zanthoxyli were found in TLC ; The linear range of berberine hydrochloride in Rhizoma Coptidis was 0. 052 4 - 2. 096 0ug （ r = 0. 999 7） ,the average recovery was 99.4% with RSD of 1.36%. CONCLUSION The method is simple and reproducible. It can be used to control the quality of the external used washing powder for Hemorrhoid.
