Objective： To optimize depigmenting technology of polysaccharides from Portulace oleracea with activated carbon.Method： On the basis of single-factor tests,according to Box-Behnken center-united experimental design principles,response surface analysis of three factors and three levels was adopted with activated carbon dosage,depigmenting time and temperature as factors.A second order quadratic equation for decolorization of polysaccharides was built,after analyzed significance of three factors,optimal decolorization conditions of polysaccharides solution was concluded.Result： Optimal decolorization technology were as follows： the amount of activated carbon 30 g.L-1,decolorization time 50 minutes,decolorization temperature at 40 ℃.Under these conditions,decolorization rate of polysaccharides was up to 68.05%.Conclusion： This optimized decolorization technology was simple and stable with good predictability.
