Abstract
Six main flavonoid glycosides were isolated, for the first time, from the ethanol extract of Alhagi maurorum Boiss (Leguminosae).. They were identified as kaempferol, chrysoeriol, isorhamnetin, chrysoeriol-7-O.-xylosoid, kaempferol-3-galactorhamnoside, and isorhamnetin 3-O.-β-D-apio-furanosyl (1-2) β-D-galactopyranoside. Their identities were established by m.p., UV, EI-mass, Fab-mass, 600 MHz 1H and 13C NMR. The total extract (300 and 400 mg/kg) and two of the isolated compounds (chrysoeriol 7-O.-xylosoid and kaempferol-3-galactorhamnoside, 100 mg/kg each) showed a very promising antiulcerogenic activity with curative ratios 66.31%, 69.57%, 75.49%, and 77.93%, respectively.
