AIM: To establish chromatographic fingerprint of Panax gingseng C.A.Mey.by HPLC. METHODS: Separation was performed on an Agilent ZORBAX SB-C_(18)(4.6 mm?250 mm,5 ?m) analytical column with mobile phase consisting of acetonitrile and water with gradient elution with the flow rate 1.0 mL/min and the column temperature at 40 ℃.The UV wavelength used for detection was set at 203 nm and the analysis time was 90 min. RESULTS: 18 co-peaks on the HPLC fingerprints of Panax ginerseng C.A.Mey.were indicated.The similarities were determined by cosine.The results of similarity analysis were 0.90～1.00. CONCLUSION: Perfect fingerprints were obtained which can be used for the quality control of Panax gingseng C.A.Mey.
