Determination of Amygdalin in Apple Core by Capillary Electrophoresis

This paper investigated the determination of amygdalin content in Apple Core by high performance capillary electrophoresis (HPCE) method. The borax solution of 20 mmol concentration containing 15% methanol was chosen as buffer solution. The experiment was performed at a constant voltage of 18kV and UV detection wavelength of 210 nm. The content of amygdalin in Apple Core was 3.432 mg/g (RSD = 4.5%) (n = 6). The recovery was in the range of 88.1% - 115.7% (n=5). This method is suitable for the detection of the content of amygdalin in Apple Core.
