| 中文摘要:目的 建立一种薄层色谱-表面增强拉曼光谱法对染色掺伪的西红花进行检测。方法 将乙醇溶液润湿的西红花按压在表面喷有银溶胶的薄层板上，然后对按压区域进行表面增强拉曼散射（SERS）检测。依次对润湿剂的浓度、银溶胶的喷洒时间和喷洒量等因素进行优化。结果 成功检测经金胺O、新品红、柠檬黄和胭脂红4种常见染料染色的西红花药材。结论 薄层色谱-表面增强拉曼光谱法可实现对染色西红花简单、快速、灵敏的检测要求，并满足现场快速检测的需求。 |

| TLC-SERS for detection of the dyed Croci Stigma |

| Abstract:Objective To establish a thin layer chromatography-surface-enhanced Raman scattering(TLC-SERS) method for the detection of dyed Croci Stigma. Method The dyed Croci Stigma was wetted by ethanol and pressed on TLC plate sprayed with Silver sol. The pressed zone was immediately detected by a portable Raman spectrometer. Factors including the concentration of ethanol, spraying time and amount of silver sol were investigated and optimized. Results The dyed Croci Stigma, stained by auramine O, new fuchsin, tartrazine and brilliant ponceau were successfully detected using the established method. Conclusion The combination of TLC and SERS technology provides a rapid, simple and sensitive detection method which is suitable for quick field tests. |
