中文摘要:
对超声强化超临界CO2萃取柑橘落果中活性成分辛弗林进行研究,并对不同方法的萃取物进行比较。结果表明:超声强化超临界CO2萃取柑橘落果中辛弗林的最佳工艺条件为:超声功率250 W、萃取温度45℃、萃取压力20 MPa、流体流量9 L/h、夹带剂含量12%、萃取时间4.5 h,辛弗林萃取率达到43.9%。其萃取物中辛弗林的含量为51.2%,高于超临界CO2法萃取物中辛弗林的含量(44.7%),远高于溶剂法萃取物中辛弗林的含量(4.6%)。
英文摘要:
Ultrasound-assisted extraction of synephrine from citrus dropt fruits by supercritical CO2 was studied in this paper.Then the content of synephrine extracted by ultrasound-assisted supercritical CO2 was compared with synephrine extracted by ethanol and that extracted by supercritical CO2.The result showed that the optimum extraction technique were ultrasound power 250 W,temperature 45 ℃,pressure 20 MPa,CO2 flow rate 9 L/h,modifier 12%,time 4.5 h.Under above conditions the extraction rate could reach 43.9%.The content of synephrine extracted under above conditions was 51.2%,which was higher than that(44.7%) of synephrine extracted by supercritical CO2 and far above that of synephrine(4.6%) extracted by ethanol.
