中药龙齿与龙骨X-射线衍射鉴别研究

目的:建立龙齿与龙骨X-射线衍射图谱,并对其进行品质评价及真伪鉴别。方法:用粉末X-射线衍射技术对样品进行分析,得到衍射图谱,并作聚类分析和相似度评价。结果:建立了以10个共有峰为特征指纹信息的龙齿与龙骨X-射线衍射图谱分析方法,并获得了一龙骨伪品图谱;样品中不同来源的龙齿相似度接近,表明其品质较均一,而不同来源的龙骨相似度相差较大,表明其品质差异显著。结论:X-射线衍射图谱分析方法可用于龙齿与龙骨的鉴别研究,并可快速检出龙骨伪品。

Identification of Dens Draconis and Os Draconis by XRD Method

Objective:To establish an XRD method for evaluating the quality of Os Draconis and Dens Draconis and applying in judgement of the counterfeit.Methods:Dens Draconis,Os Draconis and the counterfeit of Os Draconis were analyzed by XRD.Their diffraction patterns were clustered analysis and evaluated their similarity degree.Results:Established the analytical method of Dens Draconis and Os Draconis basing the features fingerprint information of the 10 common peaks by XRD pattern.Obtained the XRD pattern of the counterfeit of Os Draconis.The similarity degree of separate sources of Dens Draconis was high,while the similarity degree of separate sources of Os Draconis was significant different from each other.Conclusion:This method can be used for identification and evaluation of Os Draconis and Dens Draconis.It also can be used for identification the counterfeit of Os Draconis effectively.
