ABSTRACT
Objective The properties of anthocyanins in Suaeda heteroptera Kitag.were investigated.Methods Properties of the extract were determined via spectral absorption,physco-chemical analyses.Results Spectrogram results showed that the red pigment was classified to anthocyanins.The color properties of the pigment were similar to plant anthocyanins and pH changes could affect the tone of the color.The pigment was soluble in water,alcohol;slightly soluble in acetone;and insoluble in petroleum ether.Under natural light,degradation of the pigment could be accelerated.High temperature was disadvantage to the pigment stability.Redox stability was very low.Fe~(2+),Mg~(2+),Cu~(2+) and Mn~(2+) did not significant affect the tone of the color.Conclusion The pigment from Suaeda heteroptera Kitag.is water-soluble anthocyanins,and may be important nature edible pigment resource.
