HPLC fingerprint and UV–Vis spectroscopy coupled with chemometrics for Curcumae radix species discrimination and three bioactive compounds prediction
Microchemical Journal（2021）
Abstract
•HPLC fingerprints of single species and full samples were separately developed.•UV–Vis spectra showed there were three peaks in Huangyujin and one in others.•Discrimination models were respectively established based on the two techniques.•Quantification models based on UV–Vis spectra were used to determine three compounds.
