In order to detect adulterated radix notoginseng on the market,a method based on three-dimensional synchronous fluorescence spectroscopy for fingerprint is developed.Three-dimensional synchronous fluorescence spectra of radix notoginseng powder and its adulterants(Curcuma zedoaria powder,wheat flour)are measured by using FLS920 spectrometer.It can be found that each material is fluorescent,but the lines are different.Three-dimensional synchronous fluorescence spectra of mixtures of radix notoginseng powder and its adulterants are measured and there are significant differences between them.Experimental results indicate that the combination of synchronous fluorescence spectroscopy method and threedimensional fluorescence spectroscopy method can significantly improve the selectivity and sensitivity,with a distinct advantage in a complex multi-component mixture for fluorescence spectroscopic analysis.The study can help to identify the component and the quality of Chinese patent medicine,also can provide the reference for establishing a complete fingerprint of Chinese traditional medicine.
