沉香及其伪品的鉴定方法研究进展

Research progress of identification methods of Lignum aquilariae resinatum and its counterfeits

沉香伪品来源较多,沉香及其伪品的鉴别方法中,性状鉴别是最简单、直观的方法,在实际鉴定工作中,应多方法相辅相成,相互补充,建议在沉香的鉴别中采用以醇溶性浸出物含量、HPLC指纹图谱结合显微鉴别为主,以理化鉴别反应和薄层色谱分析为辅的方法。多技术结合、建立特征指纹图谱数据库是未来沉香及其伪品鉴别技术的发展趋势。

There are many sources of Lignum aquilariae resinatum counterfeits. Among the identification methods of Lignum aquilariae resinatum and its counterfeits, the morphological identification is the simplest and most intuitive. During the practice, many methods should be applied together and complemented with each other. It is recommended that the alcohol-soluble extract content, HPLC fingerprint combined with microscopic identification are the main method, supplemented by physical and chemical identification reaction and thin layer chromatography. Moreover, the combination of multiple technologies and the establishment of a characteristic fingerprint database is the future development trend of Lignum aquilariae resinatum and its counterfeit identification technology.
