Determinação de compostos fenólicos no pedúnculo de caju

Abstract

The cashew, a false fruit originated from the cashew tree (Anacardium occidentale), presents a high nutritious value, rich in vitamin C, besides containing carotenoids and phenolic compounds. In this work, an avaluation of the Nuclear Magnetic Resonance (NMR) profile and the use of solid phase extraction to identify and characterize chemical compounds was performed. The cashew extract was obtained with extraction using C18 cartridge with water and methanol as solventes, thus submitted to reversed-phase liquid chromatography, obtaining twelve fractions which were analysed by Liquid Chromatography coupled to Mass Spectrometer (UPOLC-QTOF). The chemical investigation resulted in the characterization of nine substances. The structures of all the identified substances were discovered through spectromic methods (MS-ESI) besides compairing with the available data in literature.
