Chemical Composition and Antioxidant Activities of the Oleoresin from the Clove Buds (Syzygium Aromaticum)

Abstract

The chemical composition and antioxidant activities of the oleoresin from clove buds were investigated in this work. The results showed that 20 compositions of the oleoresin were identified, and eugenol (72.85%) was found to be the main components of the oleoresin, followed by eugenyl acetate (10.54%), β-caryophyllene (4.54%), and d-cadinene (3.88%). The oleoresin from clove buds had the better scavenging capacity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 2’-azino-bis (3-ethylbenothiazoline-6-sulfonic acid) diammonium salts (ABTS) radicals, and inhibiting lipid peroxidation reaction in lard emulsion, as well as exhibited different protection effects against DNA damage caused by Fe2+ and 2,2′-azobis (2-methylpropionamidine) dihydrochloride (AAPH). And the antioxidant activities of oleoresin showed a dose-response relationship to some degree. However, the oleoresin did not have the protection against protein damage, but had a prooxidant effect on protein oxidative damage.
