目的:探索中药材苍术新的鉴定方法。方法:运用粉末X射线衍射Fourier特征图谱法对苍术药材进行扫描分析。结果:对8份不同产地苍术饮片及苍术对照药材进行分析,获得了苍术的X射线衍射Fourier特征图谱及特征标记峰。结论:苍术的X射线衍射Fourier谱重复性好、特征性强,具有指纹特征,可作为鉴别指标。经X射线衍射Fourier谱对比分析,南、北苍术的衍射图谱几何拓扑特征有明显差异。
Objective: To explore the new identification methods of Chinese herbal medicine Cangzhu. Methods: The scanning electron microscopy (SEM) was used to analyze the herbaceous herbs. Results: Eight herbs from different areas of Atractylodes japonica and Herba Artemisiae were analyzed, and the X-ray diffraction Fourier characteristic map and characteristic marker peak of Atractylodes japonica were obtained. Conclusion: The herb spectrum of X-ray diffraction Fourier spectrum has good repeatability, strong characteristic and fingerprint characteristics, which can be used as the identification index. By X-ray diffraction Fourier spectrum contrast analysis, South, North Atractylodes diffraction topography of the geometric topological characteristics are significantly different.
