银杏叶片的粉末X-射线衍射Fourier指纹图谱分析

摘要

采用粉末X-射线衍射法对7个不同厂家的银杏叶片进行分析,获得了各样品的粉末X-射线衍射Fourier指纹图谱.根据银杏叶提取物的粉末X-射线衍射Fourier图谱的几何拓扑图形和32个特征共有峰,研究了银杏叶片的粉末X-射线衍射Fourier指纹图谱的图形几何拓扑规律,并计算了其特征共有峰的比例,为银杏叶片的质量鉴定提供了参考依据.%Powder X-ray diffraction analysis was used to analyze tablets of Ginkgo biloba L. from different manufacturers. The powder X-ray diffraction Fourier fingerprint patterns of these samples were obtained. Based on the geometry topology of powder X-ray diffraction Fourier fingerprint pattern and 32 characteristic peaks of the extract of Ginkgo biloba L. , the geometry topology law of powder X-ray diffraction Fourier fingerprint pattern of the tablets of Ginkgo biloba L. was studied,and the proportions of characteristic peaks were calculated. It could be used as reference for the quality identification of the tablets of Ginkgo biloba L..
