Araçás species have been used in traditional medicine for possessing several pharmacological properties such as antiseptic, digestive, anti-hemorrhagic, controlling blood pressure and diuretic. This study aimed to make a pharmacognostic characterization to establish control parameters of the plant drug quality (leaf), the determination of phenolic compounds, flavonoids, tannins, vitamin C and β-carotene, and to evaluate the powder antioxidant capacity of Psidium cattleianum leaf. From powder of P. cattleianum leaves, pharmacognostic analyzes were performed and quantification assays of bioactive compounds and antioxidant activity by DPPH capture using spectrophotometric methods. In the pharmacognostic characterization were determined the density (0.366 g. ml-1 ± 0.015), the ash content (17.52% ± 1.002), moisture (9.32% ± 1,006) and the pH (5.4 &p.. View More»
