Objective:To determine the dissolutions of glycyrrhizic acid in Jiuganqing capsules in order to examine its inner qualitiy.Method:The content of glycyrrhizic acid was determined by HPLC as index to determine the dissolution of glycyrrhizic acid in Jiuganqing capsules by paddle method.Result:900 mL of 0.5% SDS solution was used as solvent.Paddle method was used with rotation rate at 100 r.min-1
after 45 min
dissolution is over 75% labelled amount.Conclusion: The determination of dissolution is a feasible method for controlling the inner quality of traditional Chinese medicinal preparations.
