Phytochemical profile and antifungal action of Anadenanthera colubrina extract on the quality of maize seeds

Maize (Zea mays L.) is among the most cultivated crops in world and can be affected by several diseases, especially those transmitted seeds. The study of alternatives to fungicides used for seed treatment has a promising field essential oils. Thus, this determined phytochemical profile ethanolic extract from Anadenanthera colubrina (Vell.) Brenan evaluate its antifungal activity on sanitary physiological quality maize seeds were Jaboatão cultivar, which submitted following treatments: control (untreated seeds), commercial fungicide (dicarboximide) A. at 200, 400, 600, 800, 1,000 ppm. subjected germination tests completely randomized experimental design. Phytochemical prospecting indicated presence alkaloids, tannins, flavonoids saponins, as well major compounds lupeol, gallic acid, ferulic catechin quercetin. reduced incidence Aspergillus spp., including niger, Alternaria Curvularia spp. Fusarium all concentrations. highest concentrations (800 ppm) Penicillium yielded an effective Rhizoctonia did not present phytotoxic effect, guaranteeing viability vigor
