摘要(Abstract):

利用聚类分析、Fisher判别分析和对应分析等现代统计方法,分析了羌活药材的传统商品规格特征与10种化学成分及挥发油等定量指标之间的关联,探索将中药材传统商品规格与化学定量指标结合,综合评价药材质量等级的方法。分析结果确定了羌活药材传统商品规格定性性状间、传统商品规格与化学定量指标间的多重对应关系,确定了以羌活醇、异欧前胡素及挥发油等为质量关联的主要定量指标,构建了羌活商品规格分级和同一规格下的药材质量分等的综合定量化质量判别指数HQI(herb quality index)及对应的判别函数,建立了包含传统商品规格及规格内评价的羌活药材综合质量等级标准,即不同规格间的质量等级为蚕羌>大头羌>条羌,同一规格内部的合格药材各分为2等。研究结果揭示了羌活药材商品规格与传统定性指标、与化学成分定量指标之间内在的关系,为构建基于药材传统商品形态指标与化学成分指标的综合评价指数,对药材质量进行客观综合定量评价提供了新思路。
This paper aims to explore a comprehensive assessment method combined traditional Chinese medicinal material specifications with quantitative quality indicators. Seventy-six samples of Notopterygii Rhizoma et Radix were collected on market and at producing areas. Traditional commercial specifications were described and assigned,and 10 chemical components and volatile oils were determined for each sample. Cluster analysis,Fisher discriminant analysis and correspondence analysis were used to establish the relationship between the traditional qualitative commercial specifications and quantitative chemical indices for comprehensive evaluating quality of medicinal materials,and quantitative classification of commercial grade and quality grade. A herb quality index( HQI) including traditional commercial specifications and chemical components for quantitative grade classification were established,and corresponding discriminant function were figured out for precise determination of quality grade and sub-grade of Notopterygii Rhizoma et Radix. The result showed that notopterol,isoimperatorin and volatile oil were the major components for determination of chemical quality,and their dividing values were specified for every grade and sub-grade of the commercial materials of Notopterygii Rhizoma et Radix.According to the result,essential relationship between traditional medicinal indicators,qualitative commercial specifications,and quantitative chemical composition indicators can be examined by K-mean cluster,Fisher discriminant analysis and correspondence analysis,which provide a new method for comprehensive quantitative evaluation of traditional Chinese medicine quality integrated traditional commodity specifications and quantitative modern chemical index.
