Abstract
Chemical investigation of the extract of the whole Ammania auriculata plant resulted in the identification of 13 polyphenols, including the hitherto unknown flavonoids, kaempferol3-O-beta-(6 ''-galloylglucopyranoside)-7-O-beta-glucopyranoside, and its quercetin analogue. The structures of all isolates were elucidated by conventional methods, spectroscopic analysis, including 1D and 2D NMR, and by HRESI-MS as well.
