Abstract

Vismia guianensis (Aubl.) Choisy (Hypericaceae), a medicinal plant prevalent in the Amazon Forest region, presents anthraquinones as the main compounds. This study aims to compare the chemical composition of extracts obtained using organic solvents and supercritical CO₂ (scCO₂) under varying conditions. Additionally, mathematical models were applied to predict extraction kinetics. The results indicated that the extracts contained vismiaquinone A and physcion, among other minor anthraquinones, with scCO₂ proving to be more efficient in extracting both compounds. Notably, scCO₂ exhibited a higher selectivity for vismiaquinone A, yielding remarkably greater amounts. The mathematical modeling confirmed the consistency between the response surface method and the experimental data. In addition to demonstrating the effectiveness of an environmentally friendly extraction method, this research aims to add value to a medicinal plant widely used in Brazil, yet underexplored for its pharmacological and economic potential.

基于绿色化学原理的桂枝生物活性化合物可持续提取

贵州粘虫金丝桃属（金丝桃科）是一种常见于亚马逊森林地区的药用植物，其主要成分为蒽醌类。本研究旨在比较不同条件下用有机溶剂和超临界CO2 （scCO2）得到的提取物的化学成分。此外，应用数学模型预测萃取动力学。结果表明，该提取物中含有vismiaquinone A和physion等少量蒽醌类化合物，scCO2对这两种化合物的提取效率更高。值得注意的是，scCO2对vismiaquinone a表现出更高的选择性，产量显著增加。数学模型验证了响应面方法与实验数据的一致性。除了证明一种环保提取方法的有效性之外，这项研究的目的是为巴西广泛使用的一种药用植物增加价值，但其药理和经济潜力尚未得到充分开发。

期刊介绍： The Journal of Supercritical Fluids is an international journal devoted to the fundamental and applied aspects of supercritical fluids and processes. Its aim is to provide a focused platform for academic and industrial researchers to report their findings and to have ready access to the advances in this rapidly growing field. Its coverage is multidisciplinary and includes both basic and applied topics. Thermodynamics and phase equilibria, reaction kinetics and rate processes, thermal and transport properties, and all topics related to processing such as separations (extraction, fractionation, purification, chromatography) nucleation and impregnation are within the scope. Accounts of specific engineering applications such as those encountered in food, fuel, natural products, minerals, pharmaceuticals and polymer industries are included. Topics related to high pressure equipment design, analytical techniques, sensors, and process control methodologies are also within the scope of the journal.
