Abstract

The piquiazeiro has great importance in the Amazon, as well as used in cooking, is used in the cosmetic industry, and empirically as a medicinal product, but little is known about its potential for obtaining fungitoxic substances. This study evaluated the chemical analysis and in vitro antifungal activity of ethanolic extracts and oils of Caryocar villosum. The chemical profile of the extracts was obtained from the Thin Layer Chromatography (TLC), while the vegetable oil profile was analyzed by Gas Chromatography coupled to Mass Spectrometry (GC-MS). Different concentrations of the extracts and vegetable oils were used in biological tests. The experimental design was completely randomized in a factorial scheme with replication. The presence of flavonoids was confirmed in all extracts. The major components of the artisanal oil were oleic acid, palmitic acid, and ethyl oleate, and the major component of the industrialized oil was (Z)-9,17-octadecadienal, (Z)-octadecenal and β-sitosterol. In general, the extract of young leaves and industrialized oil showed the highest reductions in fungal colonies, and the concentrations of 40% of the extracts and 3.75 μL.mL-1 of oils caused the lowest growth of the challengers.
