Comparative study of the antioxidant activities of some lipase-catalyzed alkyl dihydrocaffeates synthesized in ionic liquid
The solubility limitations of phenolic acids in many lipidic environments are now greatly
improved by their enzymatic esterification in ionic liquids (ILs). Herein, four different ILs were
tested for the esterification of dihydrocaffeic acid with hexanol and the best IL was selected
for the synthesis of four other n-alkyl esters with different chain-lengths. The effect of alkyl
chain length on the anti-oxidative properties of the resulted purified esters was investigated
using β-carotene bleaching (BCB) and free radical scavenging method DPPH and …
