Popis: 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-kampferol and 8-methoxy-kampferol-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.
