摘要
目的:建立老鹳草药材XRD的鉴定分析新方法。方法:对老鹳草药材及其它7种易混品进行X射线衍射分析,并按2θ进行相似度计算与分析。结果:获得了老鹳草药材及其它7种易混品不同的X射线衍射Fourier指纹图谱。结论:粉末X射线衍射Fourier指纹图谱鉴定法可用于老鹳草药材与易混品的鉴定和识别,相似度的计算结果进一步证明了方法的可行性。
Objective ： To provide a X-ray diffraction （XRD） new method to identify different of herbal drugs of Geranium. Methods： Analyse X-ray diffraction Fourier pattern of 1 plants of Geranium, 7 kinds substitute, and degree of different fingerprint patterns was calculated and analyzed according to the position （2 theta value） of peaks searched. Results： Obtain the different X-ray diffraction Fourier pattern of 1 kinds plants of Geranium and 7 kinds substitutes of Geranium. Conclusion ： This method can be used for indentification on different medicinal material of Geranium.
