中文摘要:
      采用超声波辅助提取燕麦麸油，并对其体外抗氧化性进行研究。在单因素实验基础上，采用响应面实验优化超声波辅助提取燕麦麸油工艺条件。结果表明：最佳提取工艺条件为超声波功率400 W、超声温度57?℃、提取时间49 min、正己烷与无水乙醇体积比72∶?28，在此工艺条件下，燕麦麸油提取率为96.25%；燕麦麸油对·OH、O-2·、DPPH·清除能力都随着质量浓度的升高而增大，清除效果明显，当燕麦麸油质量浓度为5.0 mg/mL时，其对·OH、O-2·、DPPH·清除率分别达46.03%、47.28%、54.87%。燕麦麸油具有较强的体外抗氧化性。
英文摘要:
      The ultrasound-assisted extraction of oat bran oil and its antioxidant activity were studied. The results showed that the optimal ultrasound-assisted extraction conditions of oat bran oil were obtained by response surface methodology based on single factor experiment as follows: ultrasonic power 400 W, ultrasonic temperature 57?℃, extraction time 49 min, volume ratio of n-hexane to anhydrous ethanol 72∶?28. Under the optimal conditions, the extraction rate of oat bran oil was 96.25%. The scavenging ability of oat bran oil on ·OH, O-2· and DPPH· increased with the increase of mass concentration of oat bran oil. When the mass concentration of oat bran oil was 5.0 mg/mL, the scavenging rates on ·OH, O-2· and DPPH· were 46.03%, 47.28% and 54.87%, respectively, which indicated that the oat bran oil had strong antioxidant activity in vitro.
