The fingerprints of Achyranthes bidentata BI. by HPLC / 中成药

ABSTRACT

AIM: To establish HPLC fingerprint of Achyranthes bidentata BI..METHODS: Ten batches of Achyranthes bidentata BI from different habitats were measured by RP-HPLC,and their fingerprints were obtained.C18 column was used.Acetonitrile and water gradient elution were adopted as a mobile phase,the flow rate was 1.0 mL/min,the detection wavelength was set at 250 nm,the injection volume was 20 ?L,and the column temperature was at 30 ?C.RESULTS: Fifteen common peaks were confirmed in fingerprints.CONCLUSION: This method is simple,credible and of good reproducibility,can be used for the quality control of Achyranthes bidentata BI..
