Abstract: Objective To optimize the process conditions of the oil extraction ofseabuckthorn oil and to evaluate its antioxidant activity by anti-free radical action.Methods The extraction time and particle size of sea-buckseed oil were optimized by using the response surface software design-expert.Its antio xidant activity was studied through its anti-dpph free radical reaction.Results The best process of seabuckthorn seed oil was extracting time 3 h,material liquid than 1:8,extraction temperature 80 C,about 30 mesh size,the yield is highest at 11.13％.The optimum reaction time was 8 min in control,and with the increase of concentration,seabuckthorn oil antioxidant activity increased,when the addition amount of 4.00 ml sample,clearance rate as high as 77.62％.Conclusions This method is simple and reliable,the extraction rate is high,and the test results show that the oil has obvious anti-oxidative effect,which can be used as whitening and wrinkling products to delay the aging of human body.
