迷迭香原料采用水蒸气蒸馏法提取迷迭香精油后,残渣经干燥、粉碎,采用超临界二氧化碳提取残渣中抗氧化剂的有效成分,并以鼠尾草酸、鼠尾草酚含量作为衡量工艺的主要指标,以产品的物性和得率作为衡量工艺参数的优劣.采用L9 (33)正交实验考察压力、温度、萃取时间对产品得率等因素的影响;在正交基础上通过单因素分析水携带剂对成品物性、得率以及有效成分的影响.通过正交实验发现:当压力为40MPa、温度80℃、萃取时间2.5h可以达到较好的得率和有效成分含量,但产品为膏状类,不利于工业化生产;通过单因素实验发现:当压力为40MPa、温度80℃、水携带剂含量20%、萃取时间2.5h,产品总得率达到7.2%,鼠尾草酸含量达到32%,鼠尾草酚含量达到8.1%,产品呈粉末状、气味淡,有利于工业化生产和应用.

Rosemary active antioxidant extraction is studied.After water distillation extraction and drying,grinding process,the powder was then extracted by supercritical carbon dioxide(SFE-CO2).two aspects were considered in the evaluation:(1)the total yield of extracted effective component of the antioxidants,and (2)the physical appearance of the products.The processing parameters including pressure,temperature and extracting time are optimized by orthogonality test using L9 (33).We found that under the condition of pressure 40MPa,temperature 80℃ and extraction time 2.5 hours,the yield was the highest but with the product as a paste,which was not suitable for industrial application.When the condition changed to pressure 40MPa,temperature 80℃,water carrier content 20% and extraction time 2.5 hours,the yield of the product reached to 7.2%,the content of carsonic acid was 32%,the content of carnosol was 8.1%.The final product was a powder which make this condition best for industrial application.
