Three known flavonoids, quercetin, quercitrin (quercetin‐3‐0‐rhamnoside) and rutin (quercetin‐3‐0‐rutinoside), have been identified for the first time in the leaves of Acanthopanax senticosus Harms by using electrospray tandem mass spectrometry techniques (ESI−MS n ). The flavonoid hyperin (quercetin‐3‐0‐β‐galactoside), already known to be present, was also investigated. The diagnostic fragment ions of the aglycone quercetin were obtained in the ESI−MS n experiments, and a fragmentation mechanism proposed. Copyright © 2002 John Wiley & Sons, Ltd.
