Discrimination of Rhizoma Paridis and its Adulterants by FT-IR and HPLC Fingerprint Combined With Chemometrics

FT-IR and HPLC combined with chemometrics analysis were developed to discriminate between RP and adulterants. The chemometrics analysis using SA and OPLS-DA indicates significant differentiation in the chemical composition of these species. This research provides important chemotaxonomic references in species identification.
