  • Title: Structure identification of a prenylflavonol glycoside from Epimedium koreanum by electrospray ionization tandem mass spectrometry.
    Author: Dou J, Liu Z, Liu S.
    Journal: Anal Sci; 2006 Mar; 22(3):449-52. PubMed ID: 16733321.
    Abstract:
    A novel prenylflavonol glycoside, named acetylicariin, has been isolated from the aerial parts of Epimedium koreanum Nakai. The structure has been identified by electrospray ionization multi-stage tandem mass spectrometry (ESI-MSn) and other chemical evidence, which has been elucidated as 8-prenylkaempferol-4'-methoxyl-3-O-alpha-L-rhamnopyranosyl-7-O-beta-D-(2"-O-acetyl)glucopyranoside.
