采用一级动力学模型、Peleg模型、双中心动力学模型和修正的Gompertz方程对葡萄藤样品中白藜芦醇和葡萄苷的固液萃取进行了研究。通过比较调整后的决定系数、均方根误差和平均百分比误差值来评价模型的拟合优度。虽然两个网站的动力学模型与四个参数描述的数据更好，Peleg的模型，只有两个参数，可以解释的数据与拟合优度略有损失。修正的Gompertz方程对二苯乙烯类化合物的固液萃取过程的描述能力最差。实际应用-本研究介绍了比较知名的模型应用于解释提取动力学的二苯乙烯类化合物的葡萄藤，并确定最佳模型与其理由。数学模型提供关于它们所应用的系统和/或过程的信息。在设计和/或工艺应用阶段，有关该工艺和/或系统的任何信息都至关重要，因为在决策阶段，这些知识有助于设计人员和研究人员找到最佳设计参数和最有效的工艺条件，以优化目的。数学模型被认为是最经济的方法。
Solidliquid extraction of resveratrol and viniferin from grape cane samples was described by using first-order kinetic model, Peleg's model, two-site kinetic model and modified Gompertz equation. Goodness of fits of the models were evaluated by comparing the adjusted determination coefficient and root mean square error and mean percentage error values. Although the two-site kinetic model with four parameters described the data better, Peleg's model, with only two parameters, could explain the data with a slight loss of goodness of fit. The modified Gompertz equation showed the worst performance for describing the solidliquid extraction of stilbenes. PRACTICAL APPLICATIONS The present study introduces the comparison of well-known models applied to explain extraction kinetic of stilbene compounds of grape cane and to determine the best model with its justifications. Mathematical models provide information about the system and/or process to which they are applied. In design and/or process application stages, any information about that process and/or system has crucial importance because in the decision stages, this know-how helps the designers and researchers find the best design parameters and the most effective process conditions to optimize purposes. Mathematical models are accepted as the most economical ways for these purposes.
