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.
