Multi-stage countercurrent extraction technology, integrating solvent extraction, repercolation with dynamic and countercurrent extraction, is a novel extraction technology for the traditional Chinese medicine. This solvent-saving, energy-saving and high-extraction-efficiency technology can at the most drive active compounds to diffuse from the herbal materials into the solvent stage by stage by creating concentration differences between the herbal materials and the solvents. This paper reviewed the basic principle, the influence factors and the research progress and trends of the equipments and the application of the multi-stage countercurrent extraction.
多级逆流萃取技术融合了溶剂萃取、动态逆流再渗漉萃取，是一种新型的中药萃取技术。这种节省溶剂、节能且萃取效率高的技术，通过在药材与溶剂之间创造浓度差，最多可促使活性成分逐步从药材扩散至溶剂中。本文综述了多级逆流萃取的基本原理、影响因素、设备研究进展与趋势及其应用。
