Establishment of fingerprint of processing Gentianae scraba Bge and its mutual mode by HPLC / 中成药

ABSTRACT

AIM:To establish the HPLC fingerprint of methanol-resoluble component of processing Gentiana scraba Bge collected from different habits to provide evidence for quality control and quality evaluation of Gentiana scraba Bge.METHODS:Ten batches of processing Gentiana scraba Bge were measured by RP-HPLC,and the mutual mode was made by the similarity degree evaluating system 2004 of Chromatographic Fingerprint of Traditional Chinese Medicine promulgated by Chromatographic condition,consisted of Agilent-Eclipse-XDB-C_ 18-column and gradient elution with methanol-water,the detection wavelength was at 254 nm,flow rate was at 1.0 mL/min and the column temperature was at 20 ℃.RESULTS:The mutual mode of processing Gentiana scraba Bge was set up and the similarity of fingerprints of processing Gentiana scraba Bge from different habits was gained.CONCLUSION:According to the analysis of statistics,this method is steady,accurate with good repeatability and can be used as standardization implantation and quality control of Gentiana scraba Bge.
