摘要 考察了加热回流法提取苍耳子油的影响因素,主要包括料液比、药材粒径、提取温度和提取时间等,并在此基础上研究其提取动力学。结果表明苍耳子油较适宜的提取条件为,m(料)∶V(溶剂)为1∶9(g/mL),药材平均粒径为60目,在80 ℃下提取6.5 h。动力学研究表明在不同粒径下,苍耳子油的提取动力学符合二阶溶出动力学模型,即减小药材粒径,可明显增加有效成分提取率。研究结果可为苍耳子油的提取工艺设计和操作条件的选择提供借鉴。

Abstract: The refluxing extracting process of Siberian Cocklour Fruit oil and its kinetics were investigated.The effects of main parameters(extraction temperature,particles size,extraction temperature,extraction time,etc.)on the recovery of oil were studied and the optimal extraction technology was obtained,and then the extracting kinetics was studied.The optimal refluxing extraction conditions were as follows:alcohol was selected as solvent,the ratio of alcohol to raw material was 9∶1,refluxing 6.5 h at 80 ℃,and raw material size was 60 meshes.The study of kinetics showed that the material size had an important influence on extraction efficiency of oil,and the kinetic model was accord with secondorder.The result can be used to optimize and control the process of extraction of Siberian Cocklour Fruit oil.
