萃取是大多数科学研究的重要先决条件，涉及从生物/环境系统中分离和分析化合物。在进行提取这些物质的传统和现代方法中使用大量有机溶剂引起安全、环境问题和成本效益问题。与其他方法相比，亚临界水萃取（SWE）提供了一种合适的，安全的，具有成本效益和环境安全的替代方法，因为它利用了超临界水在高温和高压条件下（100-374摄氏度，>50巴）的特殊性质来提取非极性分析物。本文综述了SWE的原理和动力学，以及目前的应用程序作为一个可行的工具，从各种生物基质中提取化合物的关键评价。虽然需要更多的研究来提高全SWE应用，但其在植物化学物质以及其他生物活性分子（包括来自植物和动物成分的真菌毒素）的提取中的采用似乎是有希望的，并且需要被适当地利用。
Extraction is a vital prerequisite in most scientific studies involving the isolation and analysis of compounds from biological/environmental systems. The use of large quantities of organic solvents in performing both conventional and modern methods of extraction of these substances stirs issues of safety, environmental concern and cost-effectiveness. Subcritical water extraction (SWE) offers a suitable, safe, cost-effective and environmentally safe alternative compared to other methods as it takes advantage of the special properties of supercritical water under high temperature and pressure conditions (100-374 degrees C, >50 bar) to extract non-polar analytes. This review presents a critical appraisal of the principles and dynamics of SWE, and the current applications as a viable tool in the extraction of compounds from various biological matrices. Although more research is needed to improve full SWE applications, its adoption in the extraction of phytochemicals as well as other bioactive molecules including mycotoxins from both plant and animal components seems promising and needs to be properly exploited.
