摘　　要：目的建立水蒸气蒸馏法提取紫穗槐挥发油的动力学模型。方法用水蒸气蒸馏法提取紫穗槐挥发油,采用两种数学模型对挥发油提取过程实验数据进行拟合。结果动模方程为:Y=Bmaxx/kd+x,提取量与提取时间的关系方程为Y=(Y0-NS)*exp(-K*X)+NS。结论数学模型拟合程度高,结果稳定,可适用于紫穗槐挥发油提取过程的优化控制。Objective To explore the kinetics model in the extraction of essential oil from Amorpha fruticosa L. Methods Essential oil ofAmorpha fruticosa L. was extracted by wet distillation. Two mathematic models were used to fit the experiment data. Results The kinetic mathematic models are y=Bmax /（kd＋x） and Y=（Y0-NS）＊exp（-K＊X）＋NS. The optimum extraction is feasible and the result is stable. Conclusion The regression of the mathematical model is effective, which can be applied to control the essential oil extraction process optimization.
