Objective： To establish a fingerprint analysis method for Kangdu mixture. Methods： An HPLC method was used with the following chromatographic conditions： an Agilent C_（18） chromatographic column（ 150 mm × 4. 6 mm,5 μm） was applied,the mobile phase was 0. 1% phosphoric acid water and acetonitrile with gradient elution at a flow rate of 1. 0 ml·min^（-1）,the column temperature was 25 ℃,and the detection wavelength was 290 nm. Results： Under the selected chromatographic conditions,17 common peaks were identified to construct the fingerprint for 10 batches of Kangdu mixture,and the similarity of the samples was above 0. 9. Conclusion：The established method is with high precision and good reproducibility,which can be applied in the fingerprint evaluation of Kangdu mixture.
