Comparison of X-ray diffraction Fourier fingerprint pattern and similarity analysis of Chinese agarwood and Aquilaria sinensis
Objective:To study Chinese agarwood and Aquilaria sinensis by X-ray diffraction (XRD) and establish the identification method of Chinese agarwood.Methods:Eight sorts of Chinese eaglewood and Aquilaria sinensis were analyzed and the fingerprint patterns were determined by X-ray diffraction.The degree of different fingerprint patterns was calculated and analyzed according to the position (2θ) of peaks searched.Results:The similarity of eight sorts of Chinese agarwood was high,which was between 0.9096 and 0.9601,while Aquilaria sinensis (0.7917) and Chinese agarwood in the 2θ(10°-20°) were different in the spectrogram.The similarity of Chinese agarwood and Aquilaria sinensis was low.Conclusion:X-ray diffraction Fourier fingerprint can be used for identification and analysis on Chinese eaglewood,and the results of similarity calculation can be used for quality evaluation.
