Abstract:Matrine and oxymatrine in Jieeryin and Fuyanshuan were separated and determined by Reversed Phase High Performance Liquid Chromatography,A chromatographic method for the separation and determination of matrine and oxymatrine in these preparations was established.Chromatographic coditions:ODS column with methanol water triethylamine(55∶45∶0.02) as the mobil phase,and UV detection at 215nm.The method is simple,sensitive and accurate.This study provides the scientific basis for quality evaluation and quality control in making these preparations.
