中药复方系由多种药味所组成,历来有主付佐使的讲究。关于分析方中各药主次作用的方法,通常是采用拆方研究法,但因工作量很大,往往难以进行。近年来由于正交设计的试用,已增加了这种研究的可能性。中药复方的正交实验一般包括三个基本步骤:1.根据研究目的进行正交设计。2.按正交表进行实验。3.根据实验数据进行分析,形成结论。以下就复方中各药主次作用的正交实验及直观分析法的应用,结合实例作一概述。
The traditional Chinese medicine compound is composed of a variety of medicinal flavors, and has always paid attention to the chief payers. As for the method of analyzing the secondary effects of each drug in the prescription, the disassembly method is usually used, but it is often difficult to perform due to the large workload. In recent years, the possibility of such research has increased due to the trial of orthogonal design. Orthogonal experiment of traditional Chinese medicine compound generally includes three basic steps: 1. Orthogonal design according to the research purpose. 2. Experiment with orthogonal tables. 3. Analyze according to experimental data to form a conclusion. The following is an overview of the orthogonal experiment and the application of the visual analysis method for each agent in the compound prescription.
