药物发现是新药研究的重要过程,其中药物活性筛选是决定新药研究成败的关键。本文分析了目前中药复方活性筛选的8种形式,并按历史进程将筛选技术分为传统筛选技术与现代筛选技术,简述了临床前活性药物优化技术、候选药选择技术、分离技术、分子设计、分子水平筛选、生物芯片技术、药物基因组学、药物相互作用分析技术（BIA）、化学和生物信息学结合、中药复方多层区组筛选模式（MBAS模式）等现代筛选技术的特征,并探讨药物发现策略的改变和新技术应用对于中药复方活性筛选研究进程的影响。

The discovery of medicines is an important process in the study of new medicines, in which the screening of the activity of medicines constitute the master key to the success of the study on a new medicine. This article analyzes the eight forms used in the screening of the activity of compound Chinese medicines at present; divides screening technology into the traditional and modern ones; generally presents the characteristics of such modern screening technologies as the technology for the optimization of pre - clinical active medicines, the technology for the selection of medicines to be screened, the separation technology, the technology for molecule design, the technology for screening at molecular level, the technology for bio - chips, science of medicine genomes, analytical technology for the interreaction of medicines, the technology for the combination of chemistry and bio - information and the MBAS; and explores the impact of the change in the strategy for the discovery of new medicines and the application of new technologies on the progress in the study on the screening of the activity of compound Chinese medicines.
