Determination of Vitamin C Content in Brown Rice by Capillary Zone Electrophoresis

摘要

In this paper, using capillary zone electrophoresis method determined Vitamin C content in brown rice. 20 mmol/L borax solution and 20% acetonitrile concentration, 20kV voltage, 254 nm UV detection wavelength was chosen for electrophoretic analysis condition. Measured vitamin C content in brown rice was 0.043 mg/g (RSD=7.1%) (n=7).
