[Identification of traditional Chinese medicine scorpio by powder X-ray diffraction Fourier pattern].

OBJECTIVE: To set up a new analysis method of the traditional Chinese medicine Scorpio. METHODS: Ten Scorpio samples were obtained from Hubei, Shaanxi, and Shandong provinces and analyzed with X-ray diffraction Fourier pattern technique to obtain the geometric topology and characteristic marked peak of Scorpio. RESULTS: The geometric topologies of 9 samples were similar, excepting Sample 7#. Totally 11 characteristic marked peaks were observed among these 9 samples. CONCLUSION: X-ray diffraction Fourier pattern is a useful tool for the identification and quality control of the Scorpio.
