Abstract :
[en] Water soluble polysaccharides were extracted from waste residues after the industrial production of the essential oil from Deverra tortuosa plant as novel approach for valorization of these wastes. The extraction yield was 7.82%. The chemical composition, structural characterization, functional, antioxidant, antihypertensive and cytotoxic properties of the Deverra tortuosa water-soluble polysaccharides (DTWSP) were treated. This study was carried out using different techniques such as FT-IR, NMR, XRD, zeta potential and DSC to obtain the structural characterization of DTWSP. The X-ray pattern revealed the semi-crystalline behavior of DTWSP. The analysis of the monosaccharide composition by GC–MS showed the presence of glucose galactose, mannitol, gluconic acid, xylose and ribose. In addition, DTWSP exhibited important techno-functional properties (SWC, WSI, WHC and OHC). Antioxidant activities of DTWSP were determined using different antioxidant assays: DPPH radical-scavenging capacity (IC50 = 1.26 mg/ml), reducing power, ABTS assay and ferrous chelating capacity. The findings indicated that DTWSP displayed excellent antihypertensive (98.92% at 0.8 mg/ml) and antioxidant activities but low cytotoxic effects on HeLa cell lines. Overall, the results suggested that WMRP presents a promising natural source of antioxidants and antihypertensive agents. Graphical Abstract: [Figure not available: see fulltext.]
