[Study on deproteinization and decoloration in extraction of polysaccharides from Rabdosia rubescens].
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.


CONCLUSIONS
The result can establish foundation for the further study of the polysaccharides from Rabdosia rubescens.
