Abstract:
OBJECTIVETo investigate the flavonoids of Oxytropisfalcata.
METHODCompounds were isolated by column chromatography using silica gel, Sephadex LH -20 and ODS as the adsorbents. Their structures were elucidated by NMR and MS spectroscopic data.
RESULTEight compounds were isolated and elucidated as 2', 4'-dihydroxy-4-methoxy chalcone (1), 2', 4'-dihydroxy chalcone (2), 5,7-dihydroxy-4'-methoxy flavonol (3), 7-hydroxy-4'-methoxy flavanones (4), 3', 7-dihydroxy-2',4'-dimethoxy isoflavan (5), 2'-hydroxy-4'-methoxy chalcone (6), 2'-methoxy-4'-hydroxy chalcone (7), 2',4'-dihydroxy dihydrochalcone (8).
CONCLUSIONAll compounds were obtained from O. falcata for the first time.
