The aerial parts of Cressa cretica L. yielded five flavonoids that were identified as quercetin (1), quercetin-3-β-O-D-glucoside (2), kaempferol-3-O-β-D-glucoside (3), kaempferol-3-O-α-L-rhamno-(1→6)-β-D-glucoside (4) and quercetin-3-O-α-L-rhamno-(1→6)- β-D-glucoside (rutin) (5). All of the isolated flavonoids were identified by spectroscopic methods (UV, FAB-MS, ¹H-NMR and ¹³C-NMR). The isolated flavonoids except quercetin are reported here for the first time from Cressa cretica L.
