【摘要】 逆流色谱技术是一种新颖的分离技术。它是不用任何固态支撑体的液液分配层析法,则能够完全排除支撑体导致的不可逆吸附和对样品的玷染、失活、变性等影响,能实现对复杂混合物中各组分的高纯度制备量分离。本文概述了这一技术的特点、发展简史和应用情况,并就中药成分高纯度标样的制备、新药研究、高质量中间体生产和生产过程的质控等问题,对如何使此项技术为中药现代化服务提出了建议。更多还原

【Abstract】 Countercurren t Chromatography is a newly -developed separation technology.It is a liquid -liquid partitio n chro-matography without using any solid s upport material a nd in its separatio n process,the irreversible adsorpt ion and the contaminatio n,inactivation and degeneration of samples,which would h e caused by its suppo rts,can be compl etely ruled out so that large quantities of high pure compound s can be separated form complex mixtures.This paper gives a brief introduction of the characteristics,history and application of t his technology and present s some suggestions on how this technology serves the moderniz ation of tradition al Chinese medicine in such fields as the preparation o f high pure standard mat erials,the R&D of new dr ugs,the production of high -quality raw materials a nd the quality contro l of production processes.更多还原
