【摘要】 将回流提取法、水蒸汽蒸馏法,超临界萃取法对丁香叶中挥发油、丁香酚的提取进行了比较,并确定丁香叶中丁香酚的最佳提取方法和条件。结果表明,超临界萃取法比回流提取法、水蒸汽蒸馏法提取效率高。超临界萃取丁香油的最佳条件为：温度为45℃、压力为14Mpa、时间为2h、二氧化碳流量为20L/h。更多还原

【Abstract】 We compared the different methods for the extraction of Volatile oil and Eugeno in Lilac leaf,the methods are circumfluense extraction,steam distillation and CO₂ Supercritical Fluid Extraction,and to find out a better extraction method and its optimzed operating conditions.The results shows that CO₂ Supercritical Fluid Extraction are superior to circumfluence extraction and steam distillation.The best condition of CO₂ Supercritical Fluid Extraction for Eugeno are 14 MPa pressure,45℃operating temperature,2h extraction time and CO₂ fluid speed is 20L/h.更多还原
