摘　　要：[目的]获得从罗汉果中提取甜苷的动力学模型。[方法]通过比较超声波辅助法和常规提取法的甜苷提取效果,并采用2种超声波动力学模型和1种常规动力学模型进行验证。[结果]在优化试验条件下,超声辅助提取的效率比常规提取高,该过程符合动力学方程:lnC=γlnt+λ,而常规提取符合ln C∞C∞-C=Kt+ln C∞C-∞C0方程。[结论]超声波频率过高,提取温度过高,提取时间过长时超声波提取过程将不受动力学控制。[Objective] To obtain the dynamic models of extraction mogroside from Momordica grosvenori.[Method] Effects of ultrasonic-assisted and normal methods on the extraction result were compared,and the results were verified by two ultrasonic dynamic models and one normal dynamic model.[Result] The yield rate of mogroside was higher with ultrasonic method,and which was in accordance with kinetic equation;besides,the result of normal method was identical with equation.[Conclusion] The excessive ultrasonic frequency and extraction temperature would make the extraction process out of dynamic control.
