Antioxidant Activities and Lipid Peroxidation Inhibition Capacities of Thymoquinone, Thmol and Carvacrol

Phenolic compounds possess an aromatic ring bearing one or more hydroxyl substituent and most are of plant origin. these bioactive components found in plant essential oils have been used as therapeutic agents because they are natural sources of antioxidants, inactivate free radicals, reduce oxidative stress, and have taken place in pharmaceutical, cosmetic and food research fields. in this review, phenolic compounds thymoquinone, thymol and carvacrol that can be used instead of synthetic antioxidants in the food industry were examined. thymoquinone is the main active ingredient of nigella sativa l., which has been used for centuries in the treatment of various animal and human ailments in world history. thymol and carvacrol are known as the main components of thyme and its derivatives, which are widely used in pharmacology. since various studies have investigated the antioxidant activities of thymoquinone, thymol and carvacrol and their potential to prevent lipid oxidation and to reduce the possible effects of oxidation, the studies conducted on this subject are summarized in this study.
