摘要: 目的建立基于整体柱的表面增强拉曼光谱(surface enhanced Raman spectroscopy, SERS)法快速检测非法染色的青黛。方法采用混合溶剂乙醇-水(1:1,V/V)对染色青黛中的染料进行提取,利用整体柱中网状孔隙有助于银纳米颗粒在空间上耦合的特性,将样品溶液和银胶溶液混匀后滴加于整体柱上进行SERS光谱采集。结果此法可得到青黛中染色掺伪量低至500 μg/kg的孔雀石绿SERS信号。结论该方法具有快速、简便、专属性强等优点,可运用于中药材青黛非法染色的快速检测。

Abstract: Objective To develop a rapid SERS detection method based on monolithic column for detection of dye adulterated natural indigo. Methods The dyes in natural indigo were extracted and mixed with silver colloid. The spectra were recorded after applying the mixture solution to the monolithic column since the intertwined pores in monolithic column could contribute for the distribution of silver nanoparticles. Results SERS signals of malachite green dyed natural indigo at quantity as low as 500 μg/kg could be obtained. Conclusion This simple,fast and specific SERS detection method based on monolithic column could be used for rapid detection of stained natural indigo.
