中药材性状特征的质量评价

性状特征既是中药材传统的鉴定特征，同时也是质量标准。目前在中药材化学成分研究及化学质量标准制定中，往往忽略了性状特征的质量评价。作者从多年数学和科研工作中感到中药材性状特征的质量意义尚有深入系统全面研究的必要。应该从以下３方面进行质量评价的研究：性状特征与道地药材的相关性；性状特征与内在化学成分的相关性；性状特征与疗效的相关性。

Quality Evaluation of Pharmacognostic Characteristic Features of Chinese Crude Drugs

Pharmacognostic characteristic features is not only the traditional approach to identify Chinese crude drugs, but also can be regarded as a quality criterion of the same drug. At present, these approaches were often neglected in the study of chemical composition of Chinese crude drugs and stipulation of quality criterion. The authors, based on their years of teaching and research experiences, expounded that the following three aspects should be observed during the evaluation of the quality of a crude drug; correlation between pharmacognostic characteristic and geo-herbalism ; correlation between pharmacognostic characteristics and intrinsic chemical composition; and correlation between pharmacognostic characteristics and therapeutic effect.
