“…QC methods for herbal drugs have been published and reviewed using FT-IR and Raman spectroscopy [38,39]. Different grades of Panax notoginseng powders can be directly differentiated by using FT-IR and 2D FT-IR [40]. A combination of ATR-FTIR micro-spectroscopy imaging can be applied directly for identifying complex mixtures of powdered herbal drugs [41].…”

“…The peak at 1,368 cm À1 corresponded to NO 3 À , indicating the signature of nitrate in the samples. 52 The peak at 53 The peaks at 923 and 862 cm À1 represented the stretching vibration of C-C and the bending vibration of C-H, respectively. 54 According to the original spectrum, the different origins could not be directly discriminated from the spectra only by the naked eye; this was owing to the similar chemical composition of P. notoginseng samples.…”

“…47 The band near 1640 cm À1 may contain the bending vibration absorption peak of the hydroxyl group and the stretching vibration absorption of the conjugate carbonyl group, as well as the vibration absorption of the aromatic compound skeleton. 45 Small band 1250 cm À1 is assigned to the asymmetric vibration of (═C-O-C) or attributed to the vibration of (-C(CH 3 ) 2 -), which can be found in C-4 or C-25 of dammarane saponins. 48 In addition, the peak near 1039 cm À1 was attributed to C-C-O or C-C-OH vibration.…”
