【Abstract】 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 spectral band of the ephedrine molecules can be obtained by TLC in the samples of about 8μg,and expounds characteristics of the sample molecules and the silica gel.Therefore,it’s clarified that the main chemical composition of Chinese medicines can be carried as finger\|print type appraisal by combining TLC and SERS.\;更多还原
