Natural rosemary extract antioxidant effect

Antioxidant action mechanism. Rosemary is now recognized as a highly effective natural antioxidant. Antioxidants can be divided into:

(1) Free radical terminators, most of which are phenolic compounds, such as tertiary butyl hydroxyanisole (BHA), di tertiary butyl hydroxytoluene (BHT), tertiary butyl hydroquinone (TBHQ), and tocopherol;

(2) Reducing agents, such as ascorbic acid and its salts, sulfite and its salts, riboflavin, etc;

(3) Chelating agents, such as EDTA citric acid, phytic acid, etc;

(4) Unilinear oxygen inhibitors such as carotene. Rosemary antioxidant is not only a free radical terminator, but also a singlet oxygen inhibitor.


In addition to flavonoids, the antioxidant components extracted from rosemary are mainly salvianolic acid, salvianolic acid, rosmarinic acid, and rosemarin, all of which have active sites of phenolic diterpenoids. In addition, rosemary also contains a variety of different phenols, such as rosemary diphenol and rosemary quinone, which are used in conjunction with each other to demonstrate overall antioxidant activity. These antioxidant components of rosemary, as chain breaking free radical terminators, inhibit the progress of peroxidation chain reactions by capturing peroxy free radicals. Due to the relatively stable phenolic free radicals generated, they react slowly with lipid compounds, thereby blocking the transmission and growth of free radical chains and inhibiting the progress of the oxidation process.

Rosemary acid

Rosmarinic acid is a phenolic acid compound with certain physiological activity. Its structural characteristics are that there are four - OH groups on two benzene rings. Therefore, it is an effective antioxidant component in rosemary. The experimental results indicate that rosmarinic acid has a mild antithrombotic effect, and its mechanism may be related to its anti platelet aggregation and increased fibrinolytic activity.
