[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 samplies.Conclusion X-ray diffraction Fourier pattern is a useful tool for the identification and quality control of the Scorpio.
