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.
