Processing of cocoa (Theobroma cacao L.) beans responsible for agricultural exports leads to large amounts of solid waste that were discarded, however, this one presents high contents of metabolites with biological activities. The major objective of this study was to valorise cocoa agroindustrial residue obtained by hydraulic pressing for extract rich in antioxidants. For it, the centesimal composition of residue was investigated, the green extraction was carried out from the residue after, the bioactive compounds, sugar contents and screaming by HPTLC were quantified for extract. The extract has a total polyphenol content of 229.64 mg/g and high antioxidant activity according to ABTS 225.0 mu M/g. HTPLC analysis confirmed the presence in the extract, residue of terpenes, sesquiterpenes, flavonoids and antioxidant activity. These results, as a whole, suggest that the extract from the cocoa residue has interesting characteristics to alternative crops with potential industrial uses. [GRAPHICS] .
