Abstract
Objective:
To study the quality standard of Changan oral solution.
Method:
Thin layer chromatography was used for identification pig's bile plaster. TLC scanning was used for the determination of hyodeoxycholic acid.
Results:
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%.
Conclusion:
This standard was capable to effectively control the quality of Changan oral solution.
