Les flavonoides de deux especes du genre Chrysosplenium

Five flavonols have been isolated from two species of Chrysosplenium; C. alternifolium contains penduletin 3,7-di-O-methylquercetagetin, 3,6,7-tri-O-methylquercetagetin and 3,3′,6,7-tetra-O-methylquercetagetin; C. oppositifolium possesses the last two compounds and 3,3′,7 tri-O-methylquercetagetin. These flavonols have been identified by chromatographic and spectral data; the taxonomic implication of this flavonoid pattern has been considered.
