The present study describes the comparation between the chemical constituents and biological properties of leaves and barks of Myracrodruon urundeuva for proposing the medicinal use of the plant from leaves, avoiding the degradation by remotion of the barks. The results of chromatographic profile of the hydroalcoholic extracts and fractions of leaves and barks showed similarities in the composition of the phytoconstituents, with variation for some of them that are in greater quantity of the bark extracts. The hydroalcoholics extracts from leaves (HELMu) and barks (HEBMu) exhibited promising 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (IC50 = 4.8 and 7.0 µg/ml, respectively), comparable to gallic acid (IC50 = 4.8 µg/ml). No significant cytotoxicity was observed in the concentrations evaluated (IC50 > 400 μg/ml). The HEBMu exhibited greater nociceptive activity than HELMu, however HELMu was more active against oral pathogens. This study provides support for the use of the leaves in traditional medicine instead of bark.
Key words: Anacardiaceae, phytochemical and chromatographic profile, biological activities, sustainable use.
