    Abstract:

    To investigate the antioxidant activities of the bee pollen extractives , water, methanol, and chloroform were used as extraction solvents and DPPH eliminating rate, ·O- removing rate, ·OH- eliminating rate, and reducing power were determined. The results showed that the water extraction had the highest yield (54.16%) while the extractives from methanol had the highest DPPH eliminating rate, ·O- removing rate, and ·OH- eliminating rate and the antioxidant activities increased with the increasing concentration. The highest DPPH eliminating rate (95.49%) was obtained under the concentration of 5g/L while the highest ·O- removing rate (80.03%) and ·OH- eliminating rate (29.14%) were obtained under the concentration of 2g/L. The chloroform extracts had the highest reducing power (49.48%) under the concentration of 5g/L. Based on the results, methanol extractives had the best antioxidant activities.
