摘要(Abstract):

目的:结合黄连(味连)的外观物性特征量化和内在品质评价指标,为味连的分级及质量评价提供实验依据。方法:分别测量14批不同产地味连的大小(总长度、总宽度、主根长度、主根直径、分枝数目、分枝长度、分枝直径、过桥长度、质量)、颜色(外部颜色、内部颜色)、含量(表小檗碱、黄连碱、巴马汀、小檗碱),采用SPSS聚类分析和主成分分析对其测定结果进行分析。结果:主成分分析选3个主因子,得出味连药材的特征指标为总长度、主根长度、主根直径、分枝长度、质量、表小檗碱含量、小檗碱含量、外观颜色总色值;聚类分析将14批样品分为2大类,道地产区与非道地产区在外观和内在质量上存在一定的差异性。结论:味连的外观物性特征量化结合内在含量指标评价,并通过数理统计处理后,可用于味连药材的分等。
Objective: Combining the quantitative physical property characteristics of the appearance with the internal quality evaluation index,its aims to provide experimental basis for the classification and quality evaluation of Coptis chinensis.Method: Fourteen batches of C.chinensis from different areas were respectively measured in size(total length,total width,root length,taproot diameter,branch number,branch length,branch diameter,length of the bridge,weight),color(external color,internal color),content(epiberberine,coptisine,palmatine,berberine).Then the determination data were evaluated by spss principal component analysis and cluster analysis.Result: Three principal components were extracted from the original data.The principal component analysis results showed that the characteristic elements might be the total length,main root length,taproot diameter,branch length,weight,the total color value of the appearance and content of epiberberine and berberine.The results of cluster analysis showed that 14 batches of samples could be clustered reasonably into two groups.In terms of the appearance and quality,there were some differences between in the geo-authentic and non-authentic producing areas of C.chinensis.Conclusion: The method which was combining the quantitative physical property characteristics of the appearance with the internal quality evaluation index,and through the processing of mathematical statistics,could be used for the the classification of C.chinensis.
