Abstract:
Using the leaves of Actinidia kolomikta as test material,taking the yield of crude polysaccharide as the response value,on the basis of single-test,the effect of homogenate extraction factors on crude polysaccharide were designed by the response surface method(RSM) to determined the optimum technology.And the antioxidant capacity of the crude polysaccharide was assessed through radical scavenging test.The results showed that the liquid-solid ratio was 17.38 mL·g-1,the rotate speed was 2.22 gear,the extraction temperature 44.54 ℃,and the extraction time was 10.49 minutes.Under the condition the yield of the crude polysaccharide from the leaves of Actinidia kolomikta was 10.69%.The radical scavenging test showed that the crude polysaccharide had antioxidant capacity,and the antioxidant capacity was proportional to the concentration of crude polysaccharide.
