Claims
- 1. An antioxidant having as an active component thereof an N-acylcarnosine compound represented by the formula (1):
- R--CO--(NH--X--CO).sub.n --OR.sup.1 ( 1)
- wherein (NH--X--CO) is a carnosine radical, R--CO is a saturated or unsaturated fatty acid radical having 6 to 24 carbon atoms, inclusive, R.sup.1 is a hydrogen atom, a sodium atom, a potassium atom, or a methyl group, and n is 1 or 2.
- 2. An antioxidant of claim 1 wherein the R--CO is a saturated or an unsaturated fatty acid radical
- 3. An antioxidant of claim 1 wherein the N-acylcarnosine compound is N-oleoyl carnosine.
- 4. An antioxidant of claim 1 wherein the N-acylcarnosine compound is selected from the group consisting of N-caprinoyl carnosine, N-oleoyl carnosine methyl ester, and N-oleoyl carnosine.
- 5. A method of protecting a substrate against oxidation which comprises the step of applying to the substrate to be protected an antioxidant having as an active component thereof an N-acylcarnosine compound represented by the formula (1):
- R--CO--(NH--X--CO).sub.n --OR.sup.1 ( 1)
- wherein (NH--X--CO) is a carnosine radical, R--CO is a saturated or unsaturated fatty acid radical having 6 to 24 carbon atoms, inclusive, R.sup.1 is a hydrogen atom, a sodium atom, a potassium atom, or a methyl group, and n is 1 or 2.
- 6. A method of claim 5 wherein the R--CO is a saturated or an unsaturated fatty acid radical having 8 to 20 carbon atoms.
- 7. A method of claim 5 wherein the N-acylcarnosine compound is N-oleoyl carnosine.
- 8. A method of claim 5 wherein the N-acylcarnosine compound is selected from the group consisting of N-caprinoyl carnosine, N-oleoyl carnosine methyl ester, and N-oleoyl carnosine.
