基于近红外漫反射光谱的鸡血藤药材定性分析

摘要

This study was aimed to establish an identification method for Spatholobus suberectus and its adulterants by near-infrared spectroscopy (NIRS). Near-infrared diffuse reflection spectroscopy (NIRDRS) spectra of different S. suberectus and its adulterants were acquired by using OPUS INDENT analysis software. NIRDRS spectra clustering analysis model and identification model were established and verified. The results showed that S. suberectus from dif-ferent regions and its adulterants were identified successfully by clustering analysis model and identification model. It was concluded that Spatholobus suberectus and its adulterants can be identified rapidly and non-destructively by NIRS.%目的：采用近红外光谱技术对不同产地鸡血藤进行定性和真伪鉴别分析。方法：利用近红外漫反射光谱法获取不同产地鸡血藤及其混伪品的近红外光谱图，运用近红外OPUS INDENT软件对相应的光谱图进行处理并建立定性鉴别模型。结果：建立的模型能有效地鉴别不同产地鸡血藤及其混伪品。结论：近红外光漫反射光谱法能够实现对不同产地鸡血藤及其混伪品的快速无损分析，为区分不同产地鸡血藤及其混伪品提供了一个客观的评价方法。
