This study was carried out to investigate comparision anaylsis of metabolites in mandarin leave inoculated by Elsinoe fawcetii. For the analysis of metabolites, we performed using by UPLC-MS spectrometry in gradient eluent condition by acetonitrile and water. Flow rate was 0.4ml/min. Instruments conditions were followed by detection ion mode(positive ion), scan range(MS:m/z100-1000), spray voltage (4kV) ,capillary voltage(35v), capillary temp(300℃). Several flavones were detected in inoculated pathogen compared to control.
