Abstract
From the leaves and flowers of Crataegus monogyna and C. pentagyna six new flavonoid-C- and O-glycosides respectively have been isolated and identified as 2″-O-rhamnosyl-orientin, 2″-O-rhamnosyl-isoorientin, 2″-O-rhamnosyl-isovitexin, rutin, spiraeosid, 8-methoxy-kämpferol and 8-methoxy-kämpferol-3-O-glucoside. The structure of O-rhamnosyl-vitexin and O-acetyl-O-rhamnosyl-vitexin isolated previously, have been elucidated unambigiously mainly by NMR- and MS-spectroscopy.Keywords
