Decolorization of Crude Tussilago farfara L.Polysaccharide by Resins
To select a suitable decolorizing resin for crude Tussilago farfara L. polysaccharide(TPS), the decolorization effect of crude TPS by five resins are studied. And the adsorption equilibrium of TPS pigment on the selected resin was investigated.The results show that the decolorization ratios of LS-206 is higher than those of other resins. Under optimized dynamicad sorption conditions (flow rate of 1.5BV/h,2BV of 5mg/ml TPS solution in 298K), the decoloration, deproteinization and polysaccharide recovery ratios of LS-206 resin were 90.04%, 91.42% and 85.38%, respectively. The above results show thatmacroporous anion exchange resins are suitable for the decolorization of crude TPS.
