Abstract
ObjectiveTo optimize the process conditions of the oil extraction of seabuckthorn oil and to evaluate its antioxidant activity by anti-free radical action.
MethodsThe 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.
ResultsThe best process of seabuckthorn seed oil was extracting time 3 h, material liquid than 1:8, extraction temperature 80 ℃, 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%.
ConclusionsThis 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.
