Abstract In this study, a novel two-dimensional correlation infrared spectroscopy (2DCOS-IR) is presented to rapidly characterize and discriminate polysaccharides in Panax ginseng (PGP), P. notoginseng (PNP), and P. quinquefolius (PQP) using attenuated total reflection Fourier transform infrared spectroscopy–based on single-characteristic temperature as the external disturbance (2D-sATR-FTIR). Compared with two existing 2DCOS-IR methods based on gradient heating pathways using KBr pellet (100 mi...
