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.

Experiments have verified that Tang Niao Karg (a preparation from Chinese medicinal herbs) taken orally does not decrease the blood sugar of empty stomach in mice, but markedly helps lower high levels of blood sugar and lipid induced by epinephrine and glucose in mice. For rat models of diabetes induced by 4-o-pyrincidine Tang Niao Kang can significantly lower the content of blood sugar, raise the insulin level of blood serum, and enhance the tolerance to sugar.
