English abstract The extract of the medicinal species Alternanthera brasiliana Kuntze afforded six di- and triglycosyl kaempferol and quercetin derivatives. Their structures were elucidated based on the ¹H- and 13C-NMR data and are reported here for the first time in this genus. Kaempferol 3-O-robinobioside and kaempferol 3-O-rutinoside significantly inhibited the human lymphocyte proliferation in vitro
Portuguese abstract O extrato da espécie medicinal Alternanthera brasiliana Kuntze forneceu seis derivados di- e triglicosilados de kaempferol e quercetina. As estruturas foram elucidadas com base em RMN de ¹H e 13C. Os seis flavonóides são inéditos no gênero. Kaempferol 3-O-robinobiosídeo e kaempferol 3-O-rutinosídeo inibiram mais eficientemente a proliferação de linfócitos humanos in vitro
