[Study on the quality standard of changan oral solution].
OBJECTIVE
To study the quality standard of Changan oral solution.


METHODS
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%.


CONCLUSIONS
This standard was capable to effectively control the quality of Changan oral solution.
