Rosemary is a small evergreen shrub of the genus Sage in the family Labiatae, native to Europe, North Africa, and the Mediterranean coast, and has been cultivated in China in recent years in Yunnan, Guangxi, Hainan, Hunan, Sichuan, Guizhou, Fujian, and other provinces and regions. Rosemary is a multi-purpose cash crop, from which antioxidants, rosemary essential oil, etc. can be extracted. The main components of antioxidants are diterpenoids, flavonoids, triterpenoids, and other compounds with antioxidant functions; rosemary essential oil is a liquid oil composed of more than 30 volatile components. Let's take a look at Rosemary Extract's introduction and effects.
The following is a list of contents:
Substance Description
Antioxidant effect
Rosemary Extract is widely used in cosmetics, perfumes, soaps, air fresheners, insect repellents, pharmaceuticals, animal and plant fats, animal feed, meat products, seafood, flour, sauces, seasonings, baked goods, fried products, natural colors, flavors, biological pesticides, tobacco, and other fields, especially in the treatment of hematological malignancies, cardiovascular disease, anti-cancer, HIV infection, indigestion, prevention of aging and other diseases. Cardiovascular disease, anti-cancer, inhibit HIV infection, treat indigestion, prevention of Alzheimer's disease, heart disease, hyperuricemia, and respiratory system diseases, etc., which brings much convenience to production and life. In Europe, rosemary has a long history of use as a food spice and is now used in cosmetics, food, and pharmaceuticals. Existing research shows that rosemary has obvious effects in preventing the oxidation of fats and oils and maintaining the flavor of meat, etc.
Rosemary is now recognized as a highly effective natural antioxidant.
1. Antioxidants can be divided according to their principle of action:
(1) Free radical terminators, most of the phenolic structure of compounds, such as tert-butyl hydroxyanisole (BHA), di-tert-butyl hydroxytoluene (BHT), tert-butyl hydroquinone (TBHQ), and tocopherol, etc.
(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) Monoclinic oxygen inhibitors, such as carotenoids, etc. Rosemary antioxidants are not only a kind of free radical terminator but also a kind of monoclinic oxygen inhibitor.
2. Phenols
The antioxidant components from Rosemary Extract are mainly syringol, syringic acid, rosmarinic acid, and rosemary phenol, which all have the active site of phenolic diterpenes, in addition to flavonoids. In addition, Rosemary also contains many different phenols such as rosemary diphenol and rosemary quinone, which are used in an additive manner to show the overall antioxidant properties. these antioxidant components of Rosemary Extract act as chain-breaking free radical terminators, which are used to inhibit the peroxidation chain reaction by capturing peroxyl radicals, and because the generated phenoxy radicals are relatively stable, they react with Because the generated phenolic oxygen radicals are relatively stable, they react slowly with lipid-like compounds, thus blocking the free radical chain transmission and growth, and inhibiting the progress of the oxidation process.
3. Rosmarinic acid
Rosmarinic acid is a phenolic acid with certain physiological activity, and its structure is characterized by four -OH on two benzene rings. therefore, it is an effective antioxidant component in Rosemary Extract. The experimental results showed that rosemary acid has a mild antithrombotic effect, and its mechanism may be related to anti-platelet aggregation and increase fibrinolytic activity.
Huang, Lian-Dong et al. reported that the anti-inflammatory mechanism of rosmarinic acid may be:
(1) Related to the inhibition of 5-lipoxygenase (5-LO) in the metabolism of arachidonic acid.
(2) Inhibition of complement-dependent PGI2 synthesis and interference with the activity of different pathway C3 converting enzymes.
(3) Antioxidant and free radical elimination.
