Olive leaf extract, a multifunctional natural product

Olive leaf extract is a natural product derived from the olive tree (scientific name: Oleaeuropaea L). It contains a variety of active ingredients, such as oleuropein, flavonoids, biflavonoids, low-molecular tannins, etc., among which schizocene Etherterpenes are the main active ingredients1. These components give olive leaf extract a wide range of biological activities, making it widely used in the fields of medicine, health products and cosmetics.

Active ingredients and benefits
Antibacterial effect
Olive leaf extract has a broad-spectrum antibacterial effect and can interfere with the amino acid pattern required for the growth of viruses, bacteria or microorganisms, interfering with viral infections and/or transmission by inactivating viruses or preventing viruses from molting, germinating or germinating in the cell membrane. . In addition, it can directly penetrate into infected cells and irreversibly inhibit microbial replication, having a significant effect on infectious and malignant microorganisms1.

Antioxidant and protective effects
Phenolics in olive leaf extract, such as oleuropein, are highly protective against LDL oxidation. These phenolics are able to effectively protect LDL cholesterol from oxidation, which is attributed to the anti-inflammatory effects of hydroxytyrosol. In addition, olive leaf extract can also reduce the apoptosis rate induced by 6-hydroxydopamine and has a protective effect against hyperglycemia2.

cardiovascular protection
Olive leaf extract also has protective effects on the cardiovascular system. It lowers blood pressure and reduces the risk of atherosclerosis. Studies have shown that olive leaf extract can reduce monocyte adhesion to endothelial cells, thereby reducing LDL accumulation in artery walls2.

antidiabetic effect
Olive leaf extract has also shown protective effects on glucose metabolism, enhancing insulin sensitivity and reducing plasma glucose and insulin levels. This is an important finding for people with diabetes as it can help control blood sugar levels2.

Skin care effect
Oleuropein in olive leaf extract is water-soluble and can protect skin cells from ultraviolet damage, effectively maintain skin softness and elasticity, and achieve skin care and rejuvenation effects1.

security
Oleuropein in olive leaf extract is very safe and does not cause toxicological effects even at high doses. Researchers have tried to test the toxicity of oleuropein by continuously supplying ultra-high doses of oleuropein to albino mice, but no deaths were found4.

Application areas
Olive leaf extract has a wide range of applications, including but not limited to the following:

Medicine: Used in the manufacture of antibacterial, antiviral, antidiabetic and other drugs.
Nutraceutical: As a supplement, provides protection against LDL oxidation, improves glucose metabolism and skin health.
Cosmetics: Used as a skin care ingredient to protect skin cells from UV damage.
To sum up, olive leaf extract is a multifunctional natural product. Its rich active ingredients and wide range of biological activities make it have important application value in many fields.
