Today is our fourth popular science article on olive leaves. In the previous articles, we introduced the origin, history and function of olive leaves.
So today we will introduce to you the application of olive leaves, and follow me to learn about it.
It can be used to manufacture new drugs for treating diseases caused by viruses, bacteria, protozoa, parasites and blood sucking insects, and for treating common cold.
In Europe and America, olive leaf extract is mainly used as dietary supplement to regulate immunity.
·skin care products
High content of oleuropein is mainly used in skin care products, which can protect skin cells from ultraviolet rays, effectively maintain skin tenderness and elasticity, and achieve the effects of nourishing and softening skin. Microherb high content oleuropein 80% is specially designed for skin care products, with high effective components and light color, which is very suitable for cosmetic formulation design.
Olive leaf essence apply to skin care products has protective, antioxidant and repair effect, specifically as follows:
1. Protection - Antioxidation - Maintaining the Viability of Skin Cells
Ultraviolet rays can cause the formation of free radicals, thus damaging skin cells and even causing cell death in the morning. Assuming that skin cells are exposed to light, look at the changes of keratinocytes and fibroblasts - some are coated with pure olive leaf extract, others are not coated. After 24 hours of observation, it is found that the cells coated with pure olive leaf extract are almost intact.
2. Protection - Antioxidant Reaction
Ultraviolet rays can also cause lipid decomposition of cell membrane. This imagination is peroxidation. Some of the skin fibroblasts were coated with pure olive leaf essence while others were not. After that, fluorescence analysis was used to measure a special substance secreted in the decomposition process to measure the degree of its peroxidation reaction. Experiments prove that pure olive leaf essence can effectively organize peroxidation reaction, thus highly protecting fiber cells.
3. Repair - Promoting Metabolism of Glutenin - Promoting Glutenin Synthesis During skin aging
the ability to synthesize Glutenin gradually decreases, and only a small amount of Glutenin can be generated by fiber cells. We measured the promotion degree of collagen synthesis in cell culture environment. Some added pure olive leaf extract while others did not. The amount of proline ( one of amino acids ) was used as an index to measure the newly synthesized collagen. Experiments show that olive leaf extract can significantly promote the production of collagen by fibroblasts.
4. Anti - glycan reaction The phenomenon of glycan reaction is a reaction that occurs in cell membrane
It will cause collagen reticulation, thus the collagen loses its original elasticity, and the skin will appear depression, i.e. wrinkles. This phenomenon gradually increases with age. After 8 days of 37C tube culture, the derivative of glycan reaction - formed between lysine and glucose - 6 - phosphate ( ester ) enzyme was tracked by fluorescence analysis. This experiment was also carried out under the condition of adding pure olive leaf essence and no pure olive leaf essence, proving its important role in anti-glycan reaction.
5. anti - gelatinase gelatinase is an enzyme produced by fiber cells under the influence of free radicals
keratinocytes will release some information under the irradiation of ultraviolet rays, thus stimulating fiber cells to produce gelatinase. Pure olive leaf essence is added to the keratinocyte culture medium and is exposed to UVA and UVB radiation. The results showed that pure olive leaf extract indirectly reduced the secretion of gluebase by inhibiting the production of " information" of keratinocytes caused by ultraviolet rays.
Well, that concludes today's article.
Olive leaf is a good thing, but what are its disadvantages and side effects that need our attention? In the next article, we will have a good talk with you about this problem.
