基于变异系数权重的模糊物元模型评价甘肃商品纹党的质量

目的:依据模糊物元模型对甘肃商品纹党进行质量评价。方法:对甘肃不同产地、不同商品等级纹党药材中5种主要成分的含量进行测定,运用基于变异系数权重的模糊物元模型对纹党药材质量进行综合评价。结果:依据欧氏贴近度数值大小,其中贴近度值0.450的样本量有18批,这些样本评价度较高,主要来自于甘肃文县、武都区的样本。商品等级为二等品的样品普遍靠前,综合排序并不以商品等级顺序排序,受产地因素影响较大。结论:该方法及模型能客观地评价纹党药材的质量,可用于其他药材质量的评价。

Evaluating Quality of Gansu Merchandise Wen Codonopsis Radix with Fuzzy Matter-element Model Based on Variation Coefficient Weight

Objective: To evaluate the quality of Gansu merchandise Wen Codonopsis Radix with the fuzzy matter-element model. Method: Content of five main components in the samples of Wen Codonopsis Radix with different commercial grades from different origins were determined. Then the quality of Wen Codonopsis Radix was evaluated by the fuzzy matter-element model based on variation coefficient weight. Result: According to the value of Euclid approach degree, there were 18 batches of samples higher than 0.450, with higher evaluation degree, mainly coming from Wen county and Wudu district in Gansu. The samples of commercial grade two were generally at the very top in ranking. The comprehensive ranking was not depending on the commercial grade, but also greatly affected by place of origin. Conclusion: The method and model can be used to objectively evaluate the quality of Wen Codonopsis Radix, and can be used for the quality evaluation of other medicinal materials.
