PMID 12575119

Abstract

To study the quality standard of Changan oral solution. Thin layer chromatography was used for identification pig's bile plaster. TLC scanning was used for the determination of hyodeoxycholic acid. The TLC identification was highly specific and the spots was clear and concentrated. Linear regression for hyodeoxycholic acid was over the range of 3.50-12.25 micrograms. The average recovery of hyodeoxycholic acid was 100.5%, RSD was 3.2%. This standard was capable to effectively control the quality of Changan oral solution.
