Establishment of HPLC Fingerprint of Homalocladium platycladum and Cluster Analysis / 中国药房

ABSTRACT

OBJECTIVE:To establish HPLC fingerprint of Homalocladium platycladum,and to carry on the cluster analysis. METHODS:HPLC method was adopted. The determination was performed on Ultimate C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid(gradient elution)at the flow rate of 0.5 mL/min. The detection wavelength was set at 360 nm, and column temperature was 28 ℃. The sample size was 10 μL. Using quercetin as reference substance,HPLC chromatograms of 13 batches of samples were determined. The similarity evaluation was carried out by using Similarity Evaluation System for TCM Chromatographic Fingerprint(2012 edition)to determine common peak. Cluster analysis were also conducted. RESULTS:A total of 12 common peaks were established in HPLC fingerprints of 13 batches of samples. The similarity was higher than 0.90. After validation,HPLC chromatograms of 13 batches of sample were in good agreement with control fingerprint. 13 batches of medicinal materials were clustered into 2 categories;S4,S6 and S10 were clustered into one category,and the rest were a category. CONCLUSIONS:Established fingerprint and cluster analysis results can provide reference for quality evaluation of H. platycladum and its exploitation and utilization.
