从天然药物中探索活性成分是阐明药效的物质基础,也是从天然界寻找类似药源或人工培育和化学合成以扩大药源的依据。对高含量或疗效特异的活性成分还可提制成纯品提供药用以保证疗效和安全药用等。我国解放以来在以上各方面都作了大量的工作,今着重将1983～1985年中的研究概况按成分类别择要分述:
Exploring active ingredients from natural medicines is the basis for elucidating the pharmacodynamics, and it is also the basis for finding similar sources of medicine or artificial breeding and chemical synthesis to expand the source of medicines from nature. The active ingredients that are specific for high levels or efficacy may also be formulated into pure products to provide drugs for efficacy and safe medical use. Since the liberation of our country, we have done a lot of work in all the above aspects. We will focus on the summary of the research in the middle of 1983-1985 according to the composition categories:
