Objective: To screen the method on deproteinization and decoloration in extraction of of polysaccharides from Rabdosia rubescens.
Methods: The effect of deproteinization with different methods was evaluated in terms of the ratio of protein removing and polysaccharide removing, the decoloration effect was also calculated.
Results: The deproteinization effect was optimal with TCA method and activated carbon also achieved a high decoloration rate.
