The optimum extraction conditions and antioxidant activities of polysaccharides from Rabdosia serra (Maxim.) Hara was studied. The extraction conditions were optimized by the single factor experiments and orthogonal experiments. Then the antioxidant activities of polysaccharides were determined by the experiments of reducing capacity and removing H2O2 capacity. Results indicated that the best extracting conditions were as follows: microwave power 480 W, treatment time 75 s,ratio of material to solvent was 1 ∶ 35 (g/mL) and extraction 2 times. Under this condition, the extraction rate of polysaccharides was 12.07 mg/g. The extracts showed obvious antioxidant activities. This method was simple, time-saving, under mild conditions. It provides a scientific basis for the exploitation and utilization of Rabdosia serra(Maxim.) Hara.
