OBJECTIVE： To establish fingerprint of Zhizi jinhua pills （ZZJHW） and analyze the relationship of it with in vitro antioxidant activity， in order to provide the basis for the quality control of them. METHODS： HPLC method was adopted. The separation was performed on a Sinochrom ODS-BP C18 （200 mm×4.6 mm， 5 μm） column with mobile phase consisted of 0.2％ acetic acid （containing 3 mmol/L sodium heptanesulfonate solution）-acetonitrile （gradient elution） at the detection wavelength of 254 nm and flow rate of  0.8 ml/min. The column temperature was controlled at 38 ℃， and injection volume was 10 μl. The “Chromatographic Fingerprint Similarity Evaluation System for TCM” （2012.130723 edition） issued by Chinese Pharmacopoeia Commission was used to evaluate the similarity of the 12 batches of ZZJHW using baicalin as reference peak so as to attribute the common peak of fingerprint. DPPH free radical scavenging assay was used to investigate the in vitro antioxidant activity of 12 batches of ZZJHW， and the relationship between its fingerprint and antioxidant activity was studied. RESULTS： The fingerprint of 12 batches of ZZJHW was established and the similarity between the fingerprint of ZZJHW with their reference fingerprint were all above 0.9 （except S1，S2，S3，S12）. 30 common peaks were marked， all of which were assigned to the herbs. Antioxidant experiment result showed the differences in the antioxidant capacity among different batches of ZZJHW； spectrum effect relationship showed that 13 common peaks were positively related with oxidation activity and 17 common peaks negatively related with it； among known components， oxidation activity components were mainly from Lonicera japonica， Scutellaria baicalensis and Rheum palmatum. CONCLUSIONS： The spectrum effect relationship of established fingerprint with its antioxidant activity can provide reference for the quality control of ZZJHW.
