Abstract: | A method was established for determining ochratoxin A in grain by high performance liquid chromatography.The linear detection ranges of ochratoxin A were 0.5-50μg/L with correlation coefficients of 0.999.The retention volume of ochra- toxin A was 2μL,the detection limit was 0.15μg/L,and the limit of quantification was 0.5μg/L.The relative standard deviations of retention time and peak area under three concentrations were between 0.03% to 0.31% and 0.41% to 1.9 l%.Recovery rates in corn spiked with ochratoxin A were between 88.3% to 96.7%. |
