Use of Carapa guianensis Aubl. agro-industrial waste as an alternative for obtaining bioproducts

Abstract

The processing of Carapa guianensis seeds to obtain oil on an industrial scale generates a significant amount of residue, approximately 66% m/m, defined as andiroba agro-industrial residue, a potential source of biomolecules. The chemical profile of the extracts from this matrix and the fingerprinting by High Performance Thin Layer Chromatography (HPTLC), as well as the spectro-scopic analysis of the NMR data (1H,13C) and comparison with data obtained in the literature, allowed the identification of two new triterpene saponins in the Carapa genus (oleanolic acid 3-O-[α-L-ramnopyranosyl-(1→2)-α-L-arabinopyranosyl] and hederagenin 3-O-[α-L-ramnopyranosyl-(1→2)-α-L-arabinopyranosyl] (Pulsatilla A)), along with three limonoids reported in the species. In this way, the research showed that even after obtaining andiroba oil, the agro-industrial residue gen-erated still has a wealth of phytochemicals, biomass that can be used as an alternative in the search for bioproducts.
