OBJECTIVETo investigate a new method for the analysis of IR fingerprint spectra of Radix Glycyrrhizae.
METHODTwo indexes, common peak ratio and variation peak ratio, are used to compare the IR spectra of various Radix Glycyrrhizae samples, and the values are calculated by means of sequent analysis.
RESULT AND CONCLUSIONThe dual-index sequence method provides a good approach to discriminate Radix Glycyrrhizae samples of different species and geographical origins.
