Publication date: February 2017 Source:Biochemical Systematics and Ecology, Volume 70 Author(s): Josiane Aline Monteiro de Oliveira, Darlon Irineu Bernardi, Rodolfo Bento Balbinot, Alexandre da Silva Avíncola, Eduardo Pilau, Marta Regina Barrotto do Carmo, Maria Helena Sarragiotto, Debora Cristina Baldoqui The phytochemical investigation on the aerial parts of Chromolaena congesta led to the isolation of nine flavonoids, known in the literature as genkwanin (1) kumatakenin (2) acacetin (3), kaempferol 3-methyl ether (4), apigenin (5), apigenin 5,7-dimethyl ether (6), apigenin 5-methyl ether (7), luteolin (8) and kaempferol (9). The chemical structures were established on the basis of spectral evidence. All the compounds were isolated from this species for the first time. The results from the present study provide further information about the flavonoids as taxonomic marker of the genus Chromolaena, and the chemotaxonomic significance of these compounds were also summarized.
