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

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 spectroscopic analysis of the NMR data ( 1 H, 13 C) 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 generated still has a wealth of phytochemicals, biomass that can be used as an alternative in the search for bioproducts.
