Study on quaity standard of Fukangbao oral solution

Objective: A quality control method was established for Fukangbao oral solution. Methods: The main drugs of the preparation were Radix Angelicae Sinensis and Rhizoma ChuanXiong. The chief effective component Ferulic acid of these drugs has been identified by thin - layer chromatography. The thin layer plate was silica gel - 3 %e CMC - Na(0. 4 mm), The developer was Benzene -Acetic Acid Glacial - Methanol(30 : 1 : 3). The fluorescence spot has been examined under ultraviolet light (365 nm). Results: There was no Ferulic acid spot in Fukangbao oral solution . Conclusion: The old technique couldn' t extract Ferulic acid (water vapor distillation) . The technique should be improved and extracted with ethanol reflux.
