| Abstract: | Objective: To study the optimum extraction and atioxidative activity of polysaceharides from the disc of sunflower.Method:The extraction of the polysaccharides were prepared by L_9 (3~4) orthogonal test plan.And antioxidative activity of the extract was evaluated by two systems, hydroxylradical system and pyrogallol autooxidation methods.Result:It was found that the optimum extraction conditions were as follows:extraction temperature 95℃ ,material - water ratio 1: 20,and extraction time 4h ,the rate of extraction was 9.73% ,and temper-ature was an important factor for the extraction rate of the polysaccharides.Conclusion:The polysaccharides from the disc of sunflower were found have strong antioxidant activity. |
