An Acylated Kaempferol Glycoside from Flowers of Foeniculum vulgare and F. DulceDOI: 10.3390/70200245 Keywords: Foeniculum vulgare, F. dulce, acylated kaempferol glycoside, spectroscopy Abstract: An acylated kaempferol glycoside, namely kaempferol-3-O-α-L-(2?,3?-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-α-L-rhamnoside) (2), quercitrin (3), isorhamnetin-3-O-β-D-glucoside (4), isoquercitrin (5), rutin (6), and miquelianin (quercetin-3-O-β-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.
