[摘要] 中药现代研究的核心问题之一是中药有效成分和有毒成分的问题，但其确定一直没有找到一条切实可行的方法，基本上处于探索阶段。结合中药的用药特色和现代药学研究成果，从中药原形化学成分的肠内细菌生物转化，到原形化学成分及其肠内细菌生物转化产物的肠吸收和转化、肝脏代谢、肾脏排泄等串联的研究模式来研究中药的有效成分和有毒成分，可能是一条适合中药特点的途径，亦是中药实验医学的重点内容之一。[关键词] 中药；有效成分；有毒成分；中药实验医学

ABSTRACT The problem on study of the active and toxic constituents of Chinese materia medica is the core of the problems in the field of modern research of Chinese materia medica. But approved methods for ascertaining the active and toxic constituents in Chinese materia medica have not been developed yet and are in developing phases. In combination with the characteristics of Chinese materia medica in clinical use and the achievements of modern pharmaceutical research, series model may be a finer approach to make certain of the active and toxic constituents from Chinese materia medica, which includes the parent compound biotransformation by human intestinal bacteria to make biotransformation products, and the absorption and further biotransformation in intestinal wall, the metabolization in the liver, and the secretion by the kidney of the parent compounds and biotransformation products. This method is also an important research assignment in the field of experimental medicine study of Chinese materia medica. ......
