一种基于声光可调滤光器-近红外光谱技术的复方丹参片快速定性分析方法

A new method for quick identification for Fufang Danshen tablets by AOTF-near infrared spectroscopy

目的:以声光可调滤光器(AOTF)-近红外(NIR)光谱技术建立复方丹参片快速定性分析方法。方法:收集不同厂家的复方丹参片,采集样品的近红外光谱,采用主成分分析法建立复方丹参片的定性分析模型(FFDS-C),并以该模型对复方丹参片验证集样品、与其相似组方的中成药和丹参、三七、冰片3种阴性对照进行定性鉴别。结果:建立的复方丹参片FFDS-C定性分析模型,能准确鉴别复方丹参片及相近的中成药和阴性对照品。结论:该方法是一种简便、快速、低耗的新型分析技术,可用于复方丹参片的快速定性鉴别。

Objective： To establish a new method using AOTF-Near infrared spectroscopy for fast identifying Fufang Danshen tablets. Method： Near-infrared spectroscopy of Fufang Danshen tablets from different factories and different bacth numbers were collected and the discriminant analysis model （FFDS-C） was established with principal component analysis. This model was applied to predict the the different samples of Fufang Danshn tablets. Result： The model can be used to precisely identify Fufang Danshen tablets from other samples. Conclusion： The method with low consumption is simple and quick and can be applied to the identification of the Fufang Danshen tablets.
