Objective] To establish HPLC fingerprints for indentification ofCordycepssinensisin Tibet. [Methods] The HPLC analysis was performed on Waters Symmetry RP-C18 column (250×4.6mm, 5μm) and detected at 260nm. The mobile phase was consisted of methnol and acetate buffer (pH 6.5) using a gradient elution. The column temperature was 25℃, and the flow rate was 0.8mL/min. The similarity of fingerprints was evaluated by the fingerprint similarity calculation software, then, duster analysis was studied. [Results] The precision and repeatability of the method were good as the relative standard deviation (RSD) of intrabatch was less than 5%. The fingerprints of 29 batches ofCordycepssinensisin Tibet, 3Cordycepssinensisfrom Sichuan and Qinghai, 2Cordycepsmilitaris, and 1 fakeCordyceps sinensiswere compared in characteristic components and similarity. The results demonstrated that Cordycepssinensiswas differentiated from theCordycepsmilitarisand fakeCordycepssinensis. [Conclusion] The method was simple, feasible and reproducible, and can be offered as technical basis for the identification ofCordycepssinensis.
