RESUMEN
Objective:To establish the HPLC fingerprint of Prunella Species from different places and evaluate it by cluster analysis.Methods:The analysis method of HPLC ngerprint was established.Alltima C18(4.6mm?250mm,5?m) was utilized for separation.The mobile phase consisted of methanol(A) and 0.5% glacial acetic acid(B) with a ow-rate of 1.0ml/min.The detection wavelength was 280nm and the injection volume was 20?l.The column temperature was 30℃.The HPLC ngerprints of Prunella Species from three di erent places were determined and analyzed by SPSS.Results:There is a big di erence among ngerprints of Prunella from di erent places.Prunella from Hubei,Anhui,Jiangxi,Guizhou,Guangxi,Sichuan were divided into a class;Henan,Jiangsu,Zhejiang were divided into another class.Conclusion:the eatsblished ngerprint showed characteristics of Prunella Species from di erent places obviously,and the attribute of Prunella Species can be distinguished e ectively by cluster analysis method.
