动态罐组式逆流提取技术在中药生产中的应用研究进展

Advances in studies on multi-stage countercurrent extraction technology in traditional Chinese medicine

动态罐组式逆流提取技术是集萃取、重渗漉、动态和逆流技术为一体的新型中药提取技术,具有提取效率高、溶剂节省、能耗低等特点。该技术主要利用药材与溶剂之间有效成分的浓度差,逐级将有效成分溶出扩散至起始浓度较低的提取溶剂中,达到最大限度转移药材中有效成分的目的。本研究对动态罐组式逆流提取技术的基本原理、影响因素、装备特点、应用研究进展及发展趋势进行了综述。

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 highextraction-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.
