| Notes | Objective To optimize the ultrasonic-assisted extraction technology of oat bran saponins,and study their in vitro antioxidant capacity.Methods On the basis of single factor experiment,response surface methodology was used to analyze the effects of ethanol concentration,ultrasonic power,ultrasonic time,extraction temperature,and extraction time on saponins extraction yield,thus obtaining the best extraction conditions.The antioxidant activity of extracts was evaluated by the DPPH,hydroxyl free radical,ABTS and super-oxide anion free radical oxidation resistance.Results The optimal extraction conditions were as follows：ethanol concentration was 90%,ultrasonic power was 284 W,ultrasonic time was 11 min,the extraction temperature was 70 ℃,and the extraction time was 180 min.Under these conditions,the extraction yield of saponins was（3.17±0.1）%.In addition,it concluded that the oat bran saponins had certain scavenging capacity of DPPH,hydroxyl free radical,ABTS and super-oxide anion free radical.Furthermore,the sc |
