摘　　要： 文章采用八角茴香为原料,以乙醇为溶剂,经超声波提取得八角茴香提取物。通过正交试验获得最佳提取条件,然后对提取物DPPH自由基清除能力和提取物对猪油抗氧化作用进行了研究。实验表明:最佳提取条件为乙醇浓度90%、料液比1∶12、超声波处理时间70 min、浸泡时间12 h,也证明了提取物具有DPPH自由基清除能力,随着浓度的增加,提取物对DPPH.自由基的清除能力逐渐增强,但对DPPH自由基的清除率低于BHT,此外提取物对猪油的自动氧化也有明显抑制作用,当提取物添加量为油样的0.15%时,其抗氧化效果与0.02%BHT相当。 Using ethanol solution as solvent,illicium was extracted by ultrasonic.The optimal extracting conditions were obtained by orthogonal test.Then carrying on study to the DPPH· free radical elimination ability and anti-oxidation activities of lard oil.Experiment result showed that the optimal extracting conditions were ethanol concentration 90%,material-solution ratio 1∶12,extracting time 70 min,marinating time 12 h,and indicated illicium extracts has the DPPH· elimination ability,along with the density increase,the extracts gradually to strengthen to the DPPH free radical elimination ability,but which is lower then BHT,in addition it also has obvious inhibitory action to lard oid auto-oxidation,when add 0.15% extracts,its anti-oxidation effect in the lard oil was equal to 0.02 BHT.
