| Abstract: | A method for the determination of dimethyl fumarate（DMF） in food was studied. The DMF in food sample was extracted with methanol, separated in C18 column with methanol -ammonium acetate buffer（ volume ratio 55：45 ） as mobile phase, determined with HPLC - diode array detector at 210 nm and measured by relative external standrard means. The linear range of the method was 1 - 16 μg/mL（ r = 0.999 87 ）. The detection limit was 0.1 μg/g. The RSD was 0.54% - 2.18% （ n = 6 ） and the recovery rate was 85.3% - 116.4%. The method is precise and convenient for the determination of DMF in food. |
