Abstract
AVILA, Mónica C. et al. ANTIFUNGAL FLAVONOIDS ISOLATED FROM Piper septuplinervium (Miq.) C. DC (Piperaceae). Rev.Colomb.Quim. [online]. 2011, vol.40, n.1, pp.25-33. ISSN 0120-2804.
Guided fractionation of ethanolic extract of aerial part of Piper septuplinervium (Piperaceae) yielded two flavonoid-type active substances against two strains of phytopathogenic fungi (Fusarium oxysporum f. sp. dianthi and Botrytis cinerea). The structures of isolated compounds were determined by spectroscopic analysis (single-and two-dimensional NMR, HRMS). The antifungal activity was determined by disk test, followed by direct bioautography against the two strains of fungi tested.
Keywords : Piper septuplinervium; Piperaceae; flavonoids; antifungal activity.
