    Abstract:
    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.
