Rapid Identification of Two Groups of Chinese Medicinals from Fossil Using Near-infrared Diffuse Reflectance Spectroscopy Method

目的:建立化石类矿物中药龙骨、龙齿、石燕和石蟹等的近红外快速识别模型。方法:用近红外漫反射光谱法结合OPUS软件,分析样品的光谱特征,建立聚类分析的模式识别方法,并验证模型的准确性。结果:这几种化石类矿物中药都有自己的特征吸收,通过模式识别技术进行快速准确地区分。结论:用近红外光谱建模,可以快速准确地鉴别龙骨、龙齿、石燕和石蟹等化石类矿物中药。

This study was aimed to establish a qualitative model of near-infrared spectroscopy in order to accurately and rapidly identify several mineral Chinese medicinals from fossil including Os Draconis, Dens Draconis, Fossil Shell of Spirifer, and Fossil Crabs. The near-infrared diffuse reflectance spectroscopy combined with OPUS software was used to analyze the spectral characteristics of these samples. The pattern recognition method was explored through cluster analysis. And the accuracy of the model was verified. The results showed that these mineral Chinese medicinals from fossil had their characteristics absorption so that they can be quickly and accurately differentiated from each other through pattern recognition method. It was concluded that based on near-infrared spectroscopic mod-eling, these mineral Chinese medicinals from fossil including Os Draconis, Dens Draconis, Fossil Shell of Spirifer, and Fossil Crabs can be quickly and accurately identified.
