Exploring the apparent properties and Q-markers for quality control of Cornus officinalis

Cornus officinalis Siebold & Zucc. has a high nutritious value and is widely used in food fields. To distinguish the quality of cornus in different areas, this research provided a new strategy for comprehensively evaluating cornus. As a result, 12 iridoid glycosides and 7 polyphenols were identified and quantified by UHPLC-Q-TOF/MS in 13 batches of samples from five different origins. Chromaticity analysis pointed out that pelargonidin-3-O-galactoside, total iridoids, and total polyphenols performed high relation with 1365*. Antioxidant activity and inhibition of α-glucosidase effect correlated with the chemical analysis suggested that iridoid glycosides and polyphenols should represent…
