The repeated column chromatographic separation of the MeOH extract of Laportea bulbifera Weddell resulted in the isolation of five flavonoids. Structures of the isolated compounds have been identified as $isorhamnetin-7-O-{alpha}-L-rhamnoside$ (1), $isorhamnetin-3-O-{alpha}-L-rhamnoside$ (2), $isorhamnetin-3,7-O-{alpha}-L-dirhamnoside$ (3), $isorhamnetin-3-O-{alpha}-L-rhamnopyranosyl-(1{ ightarrow}2)-{eta}-galactopyranoside$ (4), $isorhamnetin-3-O-{alpha}-rhamosyl-(1{ ightarrow}2)-rhamnoside$ (5) by spectroscopic means.
