Study on HPLC Fingerprint of Miao Medicine Ardisia crenata / 中国药房

ABSTRACT

OBJECTIVE:To establish HPLC fingerprints of Miao medicine Ardisia crenata.METHODS:HPLC method was adopted.The determination was performed on Diamonsil C18 column with mobile phase consiste of methanol-water (gradient elution) at the flow rate of 1.0 mL/min.The detection wavelength was 220 nm,and column temperature was maintained at 30 ℃.The sample size was 10 μL.Using 11-O-(3',4',5'-three-o-galloylhyperin)-bergeninum as reference,HPLC fingerprints of 16 batches of samples were determined.Common identification and similarity evaluation were performed by using TCM Chromatographic Fingerprint Similarity Evaluation Software (2012 edition).Cluster analysis of fmgerprrints was conducted.RESULTS:There were 6 common peaks in HPLC fingerprints of 16 batches of samples.The similarity among 8 batches was more than 0.9.The 16 batches of samples could be clustered into 4 categories.CONCLUSIONS:Established fingerprints can provide reference for identification and quality evaluation ofA.crenata.
