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.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
