An overview of Soxhlet extraction, the advantages and shortcomings of this centenary technique as well as the attempts to improve its performance and achievements reached is here presented. Assistance of high pressure, ultrasound or microwaves has decreased or minimized the negative characteristics of the conventional extractor. Automation of Soxhlet performance opened the door to commercialization of a number of different approaches. The evolution of Soxhlet extractor is here critically discussed, and the conclusion from this overview is that the adoption of new technologies to improve its performance converts Soxhlet extraction in almost a "panacea" in this field.
本文概述了索氏提取法，介绍了这项百年技术的优点和缺点，以及为改善其性能而进行的尝试和所取得的成果。高压、超声或微波的辅助作用降低或最小化了传统提取器的一些负面影响。索氏提取器的自动化开辟了商业化的大门，出现了许多不同的方法。本文还批判性地讨论了索氏提取器的发展历程，从综述中可以得出结论，采用新技术来提高其性能，使得索氏提取几乎成为该领域的“万能药”。
