A method of solvent induced phase extraction and ultra performance convergence chromatography（UPC2） was established for the determination of coumarin in Chinese traditional patent medicine and raw materials.Samples were crushed（60 mesh），and extracted with acetonitrile-water（7∶3,by volume） using dichloromethane as induced separation solvent.The targeted compound was detected by UPC2 method.The limit of detection（LOD,S/N=3） for coumarin was 0.1 mg/L.The linear range of coumarin was in the range of 0.3-10.0 mg/L.The spiked recoveries ranged from 89.8% to 102.3% and the relative standard deviations were between 0.31% and 1.0%.Compared with UPLC method，the method showed the advantages of high selectivity and low detection cost，and its analysis time is only 1/4 of the UPLC.This study provided a new pretreatment and detection method for the high throughput detection of the coumarin.
