| Abstract: | ABSTRACTSurface-enhanced Raman scattering spectroscopy was employed to analyze the biochemical composition of the Saposhnikovia divaricata decoction, which is a common traditional Chinese medicine. No reliable Raman peak was observed in traditional Raman spectra of Saposhnikovia divaricata decoction. However, 12 main Raman peaks (534, 616, 648, 685, 730, 781, 850, 958, 1242, 1319, 1460, and 1571 cm?1) were observed in the surface-enhanced Raman scattering spectroscopy spectra from the mixture of silver colloids with Saposhnikovia divaricata decoction as a result of the silver colloid enhanced effects on the Raman scattering of Saposhnikovia divaricata decoction. The results demonstrated that the surface-enhanced Raman scattering spectroscopy may provide a new kind of non-destructive, accurate, direct, and fast detecting method for the Saposhnikovia divaricata decoction or other traditional Chinese medicine in the form of decoction. |
