Abstract :
The present study analysed the antioxidant activity of the technical Cashew Nut Shell Liquid (tCNSL) using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assay and the xanthine oxidase assay, as well as in vivo evaluation by Saccharomyces cerevisiae assay. Also, the chemical composition of tCNSL was determined by gas chromatography–mass spectrometry (GC–MS), revealing the presence of cardanols (40.26%), cardols (29.95%), phytosterol (10.68%), triacontanes (4.66%) and anacardic acid (1.79%). The DPPH-based assay results showed that tCNSL 1000 μg/ml reduced the radical level by 88.9%, and the scavenging of hydroxyl radicals in the xanthine oxidase assay indicated significant antioxidant activity (IC50 = 702 μg/ml). In addition, tCNSL exerts an important protective effect against oxidative stress in yeast when used in 100–500 μg/ml concentration range, when exposed to paraquat or H2O2, indicating an in vivo antioxidant effect.
