A series of new cholesterol based Schiff base derivatives, namely cholesteryl-n-(4-((E)-(4′-cyanobiphenyl-4-ylimino)methyl)phenoxy)alkanoate (3a–j) have been synthesized and characterized by IR, NMR and mass spectral studies. In vitro antioxidant activities of these compounds were evaluated against super oxide anion radical, nitric oxide radical, DPPH radical and hydrogen peroxide and were compared with standard natural antioxidant, ascorbic acid. Our results reveal that these compounds exhibit excellent radical scavenging activities.
