Abstract

An HPLC (high performance liquid chromatography) fingerprint determination method of cough relieving Bulbus fritillariae cirrhosae and loquat dripping pills comprises the following steps: 1, cough relieving Bulbus fritillariae cirrhosae and loquat dripping pill tested substance solution preparation: preciously weighing the cough relieving Bulbus fritillariae cirrhosae and loquat dripping pills, and carrying out ultrasonic extraction of the cough relieving Bulbus fritillariae cirrhosae and loquat dripping pills by using 30-100% ethanol as an extraction solvent to prepare a tested substance solution; and 2, injecting the solution obtained in step 1 into a high performance liquid chromatograph, and determining to obtain a cough relieving Bulbus fritillariae cirrhosae and loquat dripping pill fingerprint. An HPLC method is adopted to establish the fingerprint according to the self characteristics of the cough relieving Bulbus fritillariae cirrhosae and loquat dripping pills, and optimal chromatogram conditions are found, so the determination result is precious, and has a good reappearance and a good stability.
