Objective To establish the quality control method of Chaiqin Qingre Capsules. Methods Bupleuri Radix, Forsythiae Fructus, Chebulae Fructus, and Rhei Radix et Rhizoma in the prescription were identified by thin layer chromatography (TLC);The baicalin content was quantitatively determined by high performance liquid chromatography (HPLC). Results The spots from the test solutions on the thin layer plate were clear and well separated without the negative interference. The average recovery rate of paeoniflorin was 98.39%, RSD was 0.81%. Conclusion This method is simple to operate, sensitive and accurate with strong specificity, which can be used to control the quality of Chaiqin Qingre Capsules.
