Objective: To establish TLC fingerprint of Evodia rutaecarpa for the place of production

the authenticity of identification and quality control. Method: TLC was used to analyze comparatively 12 groups of crude drugs E. rutaecarpa from Guizhou Yuqing

9 groups of crude drugs E. rutaecarpa from other different places of production and 2 Counterfeits. Result: The TLC chromatogram and the contour chromatogram of 12 groups of crude drugs from Guizhou Yuqing were very similar

which had 6 spots and 6 corresponding peaks. The intensity of each peak was different

reflecting that the content of chemical ingredients contained in E.rutaecarpa from different places were different.The main kinds of ingredient in E.rutaecarpa from different places were nearly the same

but the content of each component was different. The two kinds of counterfeits had no such characteristics. Conclusion: The method was simple and easy to operate

which can be used widely

such as rapid tests in procurement and production. And it provided a scientific basis to judge the quality of E.rutaecarpa and standardized planting of GAP

as well as to draw up the standard operating procedures of planting and the quality control of E.rutaecarpa.
