HPLC characteristic fingerprints of sedi linearis herba and sedi herba

Objective: To study HPLC characteristic fingerprint of Sedum lineare from different harvest periods,and to compare with its related species Sedum sarmentosum.Methods: The HPLC fingerprints of Sedum lineare from different collecting periods were established and compared with Sedum sarmentosum by the same detection method.Results: Hyperin,isoquercitrin and astragaloside were identified from the HPLC fingerprint of Sedum lineare.The fingerprint of Sedum lineare growing in the same area but different environment were basically identical; while there were remarkable differences of Sedum lineare growing in the same place but from different harvest periods,with the area of most common peaks changing from little to great,and slightly different peak number.The HPLC fingerprint of the two Sedum species had four common peaks,but could be distinguished from each other.The optimal harvest period of these two species should be full-bloom stage.Conclusion: The established method can provide reference for identification and quality analysis of Sedum lineare.
