OBJECTIVE Radix Panacis Quinquefolii slices and its counterfeits from different market sources were tested by the fluorescence spectra imaging technology,in order to provide a fast and non-destructive method for the identification of Radix Panacis Quinquefolii slices.METHODS Partial least square discriminant was used as the modeling method.Radix Panacis Quinquefolii,Panax ginseng and Platycondon grandiflorum,30 samples each,were detected by staring fluorescence spectral imaging instrument,and the spectral c...
