Abstract:
AB-8 resin was selected out to purify the red pigment of Amaranthus paniculatus by orthogonal design. The best conditions for isolation of the red pigment of Amaranthus paniculatus were determined as follows: pH 3, adsorption velocity 1.2 mL/min, solution adsorbent 15% ethanol and elution velocity 0.9 mL/min. After AB-8 macroporous resin purification, greatly enhance the pigment quality.
