摘　　要：为探讨"熵权法"用于当归饮片综合评价中各指标的赋权,以熵权赋权法、灰色系统理论中的灰色关联度法以及聚类分析对当归饮片的质量进行综合评价。该研究测定了44批不同来源的当归饮片样品中阿魏酸、挥发油、多糖、醇浸出物、水浸出物、水分、总灰分、酸不溶性灰分8个主要指标的含量,采用熵权法客观赋权,以相对关联度(r_i)为测度,构建当归饮片质量多指标综合评价模型。结果显示,44批当归饮片的相对关联度值的范围为0.3019~0.6629,不同来源的当归饮片质量存在一定差别,可溯源及炮制工艺标准化的当归饮片S1~S8,测得的相对关联度大,质量排序均靠前,表明实施中药饮片生产链的系统管理有利于当归饮片质量控制;44批当归饮片的质量评价结果与传统当归道地产区及目前饮片市场主流品种相符合,且与聚类分析的结果基本一致。研究表明,基于熵权赋权法的灰色系统理论可用于当归饮片的质量评价,熵权法客观赋权提高了灰色关联度法的可靠性及当归饮片质量评价的科学性。In order to discuss the"entropy weight method"for weighting various indicators in the comprehensive evaluation of Angelicae Sinensis Radix slices(ASR),the quality of ASR was comprehensively evaluated by entropy weight-based gray systematic theory and cluster analysis.In this study,the contents of ferulic acid,volatile oil,polysaccharide,alcohol extract,water extract,moisture,total ash and acid-insoluble ash in 44 batches of ASR from different sources were determined.The entropy weight method was used for objective weighting.With relative correlation(r_i)as a measure,a multi-index comprehensive evaluation model was constructed for the quality of ASR.The results showed that the relative correlation value of 44 batches of ASR ranged from 0.3019 to 0.6629.There were certain differences in the quality of ASR from different sources.The ASR S1-S8,traceable and standardized in processing techno-logy,showed a high relative correlation degree and high quality ranking,indicating that the implementation of systemic management of the production chain of Chinese herbal pieces was beneficial to the quality control of ASR.The quality evaluation results of 44 batches of ASR were consistent with those of traditional geo-authentic habitats for ASR and the mainstream varieties of ASR on market,and basically consistent with the results of cluster analysis.This study suggests that the gray systematic theory based on the entropy weighting method can be used for the quality evaluation of ASR.The objective weighting of the entropy weight method improves the reliability of the gray correlation method and the scientificity of ASR quality evaluation.
