摘　　要：研究加热回流方法提取苍耳子油的提取动力学。在二阶提取模型基础上研究提取温度与提取速率常数,初始提取速率和最大提取率之间的关系。结果表明苍耳子油提取过程提取速率常数是温度的函数,并在此基础上推导出提取率与提取温度和时间之间的关系式为:Ct=t/(1.99×10-5exp(3 065/T)+t/(0.003T-0.748))。利用此关系式能预测任意时间和温度下的提取率,可用于指导苍耳子油的工艺改进和工业化生产。The extraction kinetics of Siberian cocklour fruit oil was investigated. An extraction model, based on the assumption of a second-order mechanism for extraction, was developed to predict the rate constant of leaching, the saturated leaching capacity, and the initial extraction rate with various extraction temperatures. The rate constant is a function of the temperature, and the re- lation of yield with exteet time and temperature was deduced：Ct = t~ （1.99 x 10-2 exp （3 065/T） ＋ t/（O. 003T- 0. 748））. This study provided a reference for industrial production.
