摘　　要：用水蒸气蒸馏法提取新疆藁本挥发油,采用正交实验设计优选最佳提取工艺条件,并采用两种数学模型对挥发油提取过程实验数据进行拟合。最佳提取条件为:加水量12倍,浸泡6 h,提取5 h,氯化钠5 g。新疆藁本动模方程为:V=2.04×[1-exp(-0.01018t)](R2=0.99817)和ln(2.1-V)=-0.00944t+0.72895(R2=0.9979)。优选提取工艺可行,结果稳定。数学模型回归效果很好,可适用于新疆藁本挥发油提取过程的优化控制。Essential oil from Conioselium tataricum Hoffm was extracted by hydrodistillation and the optimum extraction conditions were determined by orthogonal design, at the same time two mathematic models were used to fit the experiment data. The optimum extraction conditions：adding 12 times water, soaking for 6 h,extracting for 5 h, adding NaCl 5 g. The kinetic mathematic models are V = 2.04×[ 1 - exp （ - 0.010 18 t） ] （R^2 =0.998 17） and ln（2.1 - V） = -0.009 44 t ＋0.728 95 （R^2 =0.997 9）. The optimum extraction is feasible and the result is stable. The regression of the mathematical model is effective, which can be applied to control the volatile oil extraction process optimization.
