Pharmacological Effects of Rosemary Extract

The antioxidants extracted from rosemary are currently recognized as the best natural antioxidants in the world. Rosemary Extract has astringent properties that firm the skin and improve blood circulation, and is therefore in high demand in the cosmetics sector, accounting for about 32% of the total demand for rosemary. Let's take a look at the pharmacological effects of Rosemary Extract.

The following is a list of contents:

• Antibacterial effects

• Antioxidant effects

• Anti-neural damage effect

Antibacterial effects

A large number of scientific studies have shown that the main antibacterial components of rosemary are α-pinene, camphor, and 1,8-cineole, all of which belong to Rosemary Extract. Using rosemary essential oil, tea tree essential oil, and lavender essential oil as materials, in vitro and in vivo antibacterial experiments were performed on mice. The results showed that rosemary essential oil had significantly higher inhibitory effects on Staphylococcus aureus, Streptococcus species, and Escherichia coli. For tea tree, essential oil, and lavender essential oil, the lung lobes of mice infected with pneumonia showed different degrees of hemorrhage, blood spots, and lung tissue lumps. Significant improvement, bleeding and blood spots gradually reduced, and hard tissue gradually became soft, close to the lung tissue morphology of mice in the negative control group.

The petroleum ether, ethyl acetate, n-butanol, and water fractions were isolated from Rosemary Extract and used to inhibit seven species of bacteria, including Escherichia coli, Salmonella and Staphylococcus aureus, etc. The results showed that at the same concentration, the petroleum ether and ethyl acetate fractions had strong inhibitory effects on seven species of bacteria, while the n-butanol and water fractions had strong inhibitory effects on seven species of bacteria. The results showed that the petroleum ether and ethyl acetate fractions were more effective in inhibiting seven bacteria at the same concentration, while the n-butanol and water fractions were less effective. Rosemary essential oil was coated with oleic acid or chloroform to form microdroplets, which were shown to inhibit the attachment and biofilm formation of Candida albicans and Candida tropicalis. The mechanism of rosemary against Escherichia coli is that the 1,8-eudesmanin compounds it contains disrupt the cell membrane of Escherichia coli. In addition, sage phenol, which is a non-essential oil component, is now also considered to have an antibacterial effect.

Antioxidant effects

Rosemary contains a variety of active ingredients, most of which have antioxidant properties, making it a natural and non-toxic antioxidant. Rosemary Extract was dissolved in triglyceride at a mass fraction of 0.4% and compared with a blank triglyceride. The peroxide value of the triglyceride with Rosemary Extract was consistently lower than the blank, indicating that Rosemary Extract has an antioxidant effect on oleaginous substances.

Anti-neural damage effect

Rosemary Extract, which contains lignan, syringic acid, and rosmarinic acid, can reduce the expression of heat shock protein 74 in nerve cells, which may improve the damage and degeneration of nerve cells under stressful conditions. Alzheimer's disease is a degenerative disease of the nervous system that occurs with nerve cell damage and death. The pathological marker of Alzheimer's disease is the deformed deposition of β-amyloid protein, and Rosemary Extract inhibits the formation of β-amyloid protein and the increase of DNA repair enzyme poly(adenosine diphosphate) polymerase (PARP) caused by it, suggesting that Rosemary Extract, which contains syringic acid, has an intervention effect on Alzheimer's disease.
