Abstract Four flavonoids from leaves of Acanthopanax Senticosus Harms were observed in negative ion mode in the electrospray mass spectra. Two of them were further isolated and identified as quercitrin (quercetin-3-O- -L-rhamnoside) and hyperin (quercetin-3-O- -D-galactoside) on the basis of MSn and NMR data. The other two compounds in the mixtures were tentatively established as quercetin and rutin ( quercetin-3-O-rutinoside) in terms of their electrospray tandem mass spectrometry (ESI-MSn) data. Three of the four flavonoids (excluding hyperin) haven't been reported in this plant before.
