Abstract
Objective: To study the method of extraction of active ingredient from complex Chinese patent medicine.
Method: Supercritical fluid extraction (SFE) has been used to extract paeonol from Liuwei Dihuang pill and HPLC was used to analyze the extracts.
Result: The methanol modified supercritical CO2 (0.4 mL x min(-1)) can effectively extract paeonol from Liuwei Dihuang pill.
Conclusion: SFE-HPLC method of off-line for analysis of extract was simple, quick and accurate.
