中药药代动力学用分析的方法,对中药多成分的复杂体系的体内动力学过程进行综合表征。探究一个或若干成分在多大程度上能够代表或表征总成分的体内动力学过程,将是研究的关键。本文以所做的工作为基础,结合有关文献,以葛根素与葛根黄酮的体内药代动力学为例,对该问题进行了较为深入讨论。结果表明:葛根素的体内动力学过程与葛根黄酮在许多方面接近,可以用其来表征葛根黄酮的体内动力学过程。同类未定性成分体内动力学特征与葛根素有较好的相关性,可以共同来表征葛根黄酮的药代特征。

The pharmacokinetics of Chinese medicines requires that the in vivo dynamics process of the complex system of multi - components of Chinese medicines should be comprehensively characterized by analytical methods. It is the key to study to what extent one component or some more can represent or characterize the process of in vivo dynamics of the total components. This article gives a rather deep exploration of this subject on the basis of the authors' study, in combination with related literatures and taking the in vivo dynamics of puerarin and the flavone of the root of kudzu vine as an example. The result shows that the process of the in vivo dynamics of puerarin is quite similar to that of the flavone of the root of kudzu vine and therefore, the former is able to characterize the latter. And the characteristics of in vivo dynamics of non - definite components of the latter's like are greatly interrelated and can characterize the latter's pharmacokinetics as well.
