Zhang J, Wang Y: [Application of surface-enhanced Raman spectra to the analysis of Chinese ephedra soup medicines]. Guang Pu Xue Yu Guang Pu Fen Xi. 1998 Jun;18(3):315-8.
A new method was developed to analyse the spectra of ephedrine in Chinese ephedra soup medicines, using surface-enhanced technique to combine thin layer chromatographic (TLC) technique with surface-enhanced Raman spectroscopy (SERS). The study indicates that the main vibrant characteristic spec tral band of the ephedrine molecules can be obtained by TLC in the samples of about 8 microg, and expounds char acteristics of the sample molecules and the silica gel. Therefore, it is clarified that the main chemical composi tion of Chinese medicines can be carried as finger-print type appraisal by combining TLC and SERS. |
