摘　　要：以香草迷迭香为原料,进行超临界CO2萃取迷迭香抗氧化剂的工艺优化,并利用响应曲面法进行试验设计、工艺参数优选。结果表明:超临界萃取迷迭香抗氧化剂的最佳工艺条件为萃取压力26.98MPa、萃取时间2.28h、夹带剂用量0.48mL/g;实际所得抗氧化剂中总酚含量达12.70mg/g。该方法简便、可靠,可用于迷迭香抗氧化剂的提取。The response surface methodology was used to optimize the supercritical carbon dioxide extraction of antioxidant components from rosemary leaves.Three extraction parameters including pressure,length of extraction time and entrainer（absolute ethanol） amount were optimized based on total phenol content in extract.The optimum extraction conditions were extraction pressure 26.98 MPa,extraction time 2.28 h and entrainer concentration 0.48 mL/g,respectively,the resulting extract containing 12.70 mg/g total phenolic compounds.The extraction method can provide a simple,reliable and applicable method for the extraction antioxidant components from rosemary leaves.
