Application of DTOPSIS Method in Quality Control of Commercial Medicinal Materials of Rheum palmatum

目的:考察不同产地、规格、生长方式掌叶大黄样品的综合质量差异,并分析差异来源。方法:测定浸出物、总灰分、酸不溶性灰分、有效成分含量,应用SPSS软件和DTOPSIS分析法进行分析。结果:四川松潘掌叶大黄质量最好,西藏昌都次之,甘肃礼县较差,差异来源于浸出物、总灰分及5个成分的含量;掌叶大黄野生品优于栽培品,差异来源于浸出物、总灰分;统货、选装货优于水根,差异来源于灰分含量。结论:应用方差分析和综合评分,可以对商品药材的品质差异进行整体描述和局部深入分析,其结果可有效应用于大黄原药材的货源筛选及质量控制方案的拟定。

Objective： To study the factors that affect the quality of Rhei Radix et Rhizoma,including those from different regions,of different specifications and different growth patterns. Methods： Detect the contents of extract,total ash,acid-insoluble ash and active ingredients of Rhei Radix et Rhizoma from 18 different sources. The results were compared by SPSS software and DTOPSIS. Results： The quality of different sources was studied from the contents of extract,total ash and content of five active ingredients. The first-class of Rhei Radix et Rhizoma was from Songpan,Sichuan,and the second-class was from Changdu,Xizang. The wild Rhei Radix et Rhizoma was superior in the contents of extract and total ash compared with the cultivated one. In terms of ash content,＂shuigen＂was inferior to the integration and the selection. Conclusion： DTOPSIS method can be effectively applied to source screening and quality control of commercial medicinal materials of Rheum palmatum.
