Abstract: The extration of raphanus staivusl pigment by macroporous resin was investigated.The absorption capacity of the resin was determined to be 0.085g/ml resin.The ethyl alcohol-acid was used for colouring agent desorption.The effect of flow rate and concentration of ethyl alcohol on desorption of pigment was studied too.

Key words: Raphanus staivusl pigment , Pigment seperation , Macroporous resin
