An acylated kaempferol glycoside, namely kaempferol-3-O-ÃŽÂ±-L-(2Ã‚Â”,3Ã‚Â”-di-E-pcoumaroyl)-rhamnoside (1) was isolated from the flowers of Foeniculum vulgare Mill. and F. dulce DC. It is thus isolated for the first time from family Apiaceae. In addition, the different organs of both plants afforded six flavonoid glycosides - namely afzelin (kaempferol-3-O-ÃŽÂ±-L-rhamnoside) (2), quercitrin (3), isorhamnetin-3-O-ÃŽÂ²-D-glucoside (4), isoquercitrin (5), rutin (6), and miquelianin (quercetin-3-O-ÃŽÂ²-D-glucuronide) (7). Structure elucidation of the above mentioned flavonoids was achieved by UV, 1H- and 13C-NMR, 1H-1H COSY, HMQC and EI-MS.
