Abstract:The optimum extraction technology and antioxidant activity of glycoprotein from Camellia oleifera seed were performed for future development and utilization of the Camellia oleifera. On the base of singlefactor experiment, the optimum parameters of extraction for glycoprotein from Camellia oleifera seed were determined by response surface methodology. The antioxidant activity of glycoprotein was examined by using various antioxidant assays with vitamin C co-assayed as positive control. As a result, the optimized condition of glycoprotein extraction was as follows: extraction time of 8.81h, salinity of 0.12mol/L, pH value of 8.77, ratio of liquid to solid of 11.62mL/g. At the optimum conditions, the yield of protein reached to 8.76%, and the yield of saccharide reached to 10.14%. The results of above antioxidant tests demonstrated that the glycoprotein from Camellia oleifera seed has certain antioxidant activities.
