RESUMEN
OBJECTIVE:To establish the HPLC fingerprints for Herba clematidis in northeast. METHODS:HPLC was per-formed on the column of Hedera ODS-2 C18 with mobile phase of acetonitrile-0.5% phosphoric acid solution(gradient elution)at a flow rate of 1.0 mL/min,detection wavelength was 338 nm,column temperature was 30 ℃,and the injection volume was 20 μL. Using rutin as as a reference,the HPLC profiles of 10 batches of H. clematidis were determined,Similarity Evaluation Software for Chromatographic Fingerprint of Traditional Chinese Medicine(2004A edition) was used for the common peaks identification and similarity evaluation. RESULTS:There were 16 common peaks in the 10 batches of H. clematidis,similarity degree was higher than 0.9. It was proved that the HPLC profiles and control fingerprint profile of 10 batches of H. clematidis had good consistency. CONCLUSIONS:The established fingerprints can provide reference for the identification and quality evaluation of H. clematidis in northeast.
