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.

Key words: Acanthopanax Senticosus Harms, Flavonoid, Electrospray tandem mass spectrometry (ESI-MSn), NMR
