[Studies on X-ray diffraction Fourier fingerprint pattern of Cornu Elaphuri Davidiani].

OBJECTIVE: To establish the analytical method for the fingerprint pattern of Cornu Elaphuri Davidiani by X-ray diffraction. METHODS: Cornu Elaphuri Davidiani from different ages and different parts were analyzed and the fingerprint patterns were determined by X-ray diffraction. The degree of different fingerprint patterns was calculated and analyzed. RESULTS: The reference X-ray diffraction Fourier fingerprint pattern and characteristic diffraction peaks of Cornu Elaphuri Davidiani were obtained by fifteen samples of Cornu Elaphuri Davidiani from different ages and different parts. CONCLUSION: This method can be used for identification and evaluation of Cornu Elaphuri Davidiani.
