Supercritical CO₂ extracts of Eugenia pyriformis leaves are potential sources of α-amyrin and β-amyrin, which are bioactive compounds with several possible pharmacological applications. Supercritical CO₂ extractions were performed to obtain kinetic curves at 60, 70, and 80 °C, and pressures of 150, 175, and 200 bar. Herein, the second order, equilibrium, as well as broken and intact cell mathematical models were evaluated, and the model based on Freundlich and Langmuir adsorption isotherm was also assessed. All tested models adequately represented the experimental kinetics and the Freundlich isotherm model best described the extraction kinetics.

超临界二氧化碳₂提取物的尤金尼亚膜虫的叶子是α-香树脂和β-香树脂的潜在来源，这是与几个可能的药理学应用的生物活性化合物。进行超临界CO ₂萃取以获得60、70和80°C的动力学曲线，以及150、175和200 bar的压力。在此，评估了二阶平衡模型以及破碎和完整的细胞数学模型，并评估了基于Freundlich和Langmuir吸附等温线的模型。所有测试的模型均能充分代表实验动力学，而Freundlich等温线模型最能描述萃取动力学。
