| Objective To establish an HPLC and HPLC-MS determination methods for illegal addition of hypoglycemic substances to health foods.Methods Samples were extracted by centrifugal vortexing methanol and determined by HPLC and HPLC-MS.The HPLC analysis was performed on a C18 column (250 mm×4.6 mm,5 μm) with methanol-0.01 moL·L-1 ammonium acetate as the mobile phase at a flow rate of 1.0 mL·min-1;the detection wavelength was at 235 nm;the column oven temperature was 30 ℃.The detector was DAD.The detector of the HPLC-MS is ESI+.Results The illegally added hypoglycemic substances had a good linear range,and the average recovery was 92.51% to 98.01%.HPLC-MS had a good separation and high specificity.Conclusions The method is simple,sensitive,reproducible,and highly specific for the determination of illegal addition of hypoglycemic substances to health foods. |
