Catalytic processes for the production of carnosol from carnosic acid are presented. The carnosic acid may be in pure form, in an impure form, part of a plant extract, or may be present in rosemary needles. The catalyst may be iron, iron salts, a minor amount of water, rosemary needeles, or a mixture thereof.

To determine the antioxidant mechanism of food phenolics against the oxidation of food components, the reaction of carnosic acid, an antioxidative constituent of the popular herbs sage and rosemary, was investigated in the presence of ethyl linoleate and the radical oxidation initiator 2,2'-azobis-(2,4-dimethylvaleronitrile). During this process, carnosic acid was oxidized to an o-quinone and a hydroxy p-quinone, the chemical structures of which were confirmed by physical and chemical techniques, From a quantitative time course analysis of the production of these quinones, an antioxidant mechanism of carnosic acid is proposed, consisting of the oxidative coupling reaction with the peroxyl radical at the 12- or 14-position of carnosic acid and subsequent degradation reactions.

Novel catalytic processes for the production of carnosol from carnosic acid using hydrogen peroxide or a peracid are presented. The carnosic acid may be in pure form, in an impure form, part of a plant extract, or may be present in rosemary needles. The catalyst may be iron, iron salts, a minor amount of water, rosemary needles, or a mixture thereof.
