Blueberries have many benefits! Study about wild blueberry extract may accelerate wound healing
Recently, according to foreign media reports, new research shows that the extract of wild blueberry can heal wounds and accelerate wound healing. Chronic wounds, such as sores and pressure sores associated with diabetes, may be classified as "non healing" because these wounds are usually accompanied by decreased vascularization (nutrient rich vascular development). Vascularization is necessary for wound healing. Researchers at the University of Maine have previously found that phenolic extracts from wild blueberries can improve angiogenesis and cell migration of human umbilical cord cells. In this new study, the team examined the effects of phenolic extracts on living wounds. Phenols are naturally occurring compounds in some foods, which can be used as antioxidants to prevent or reverse some forms of cell damage. Researchers treated a group of rats with a topical gel containing wild blueberry phenol extract. Compared with animals treated with base gel without phenolic extract and untreated control group, the treatment group showed improved migration of endothelial cells to the wound site and increased wound closure by 12%. Researchers say wild blueberries have the potential to enhance cell migration, neovascularization (angiogenesis) and accelerate wound closure. This is good news for patients with chronic wounds such as diabetes wounds, burns and pressure ulcers.
This extract in skin care products can not only soften the skin, but also delay aging
"Alpine azalea" generally grows on high mountains. It first originated in the European Alps and Pyrenees. Now it is also distributed in Emei, Daxing'an Mountains, Changbai Mountains and other places in China. Alpine Rhododendron is a kind of medicinal plant, which was first used to treat cough, phlegm and asthma. However, in recent years, people have deepened their understanding of it. People have found that it has the effects of soothing, anti-inflammatory, anti-oxidation and skin rejuvenation. Therefore, some skin care products have begun to add Alpine Rhododendron extract. Recently, scientists have carefully identified and studied the components of Alpine Rhododendron extract, identified 14 main components, and found that this small plant contains many secrets against aging, most of which are flavonoids, including quercetin, dihydroquercetin, catechin, etc. The study was published in cosmotics. The biggest feature of flavonoids is its excellent antioxidant ability, which can effectively remove free radicals from cells and prevent cell aging. Quercetin, dihydroquercetin and catechin have been mentioned. Quercetin is a natural inhibitor of CD38, which consumes nad+. Quercetin can delay aging by increasing nad+ levels. In addition, quercetin is also a light protective substance, which can effectively delay the aging of skin fibroblasts and play the effect of skin rejuvenation. Dihydroquercetin is the reduced form of quercetin. Its effect is similar to that of quercetin. It can remove cell free radicals, play an antioxidant role, and also have anti-virus, antibacterial, anti-inflammatory and other effects. It must be known that the most famous catechin is EGCG, which is very high in green tea, reaching more than 15%. It is an important substance for green tea to exert its benefits. Its antioxidant capacity is not inferior to the first two, 40~100 times that of vitamin C. In addition to anti-oxidation, it can also resist tumor, anti-inflammatory and protect heart and brain organs. It is these flavonoids that endow Alpine Rhododendron extract with anti-oxidation, anti-aging, skin rejuvenation and other characteristics. The flavonoid family is very large. In addition to the above representative substances, time school has also reported other substances, such as curcumin in curry and urushiol in strawberry.

Several plant extracts with moisturizing effect
In plants, there are sugar groups in the structure of water-soluble components such as polysaccharides and glycosides, which have good hydration and water absorption and water retention characteristics through hydrogen bonds; the phenolic hydroxyl structures in flavonoids and polyphenols also through hydrogen bonds Binds moisture, giving it the ability to absorb and retain moisture; whereas vegetable oils retain moisture primarily by forming a thin layer of oil on the skin, preventing dryness of the skin. Polysaccharide Polysaccharides are widely found in plants. The monosaccharide units in plant polysaccharides are connected to each other to form branched or linear structures, but the main chain is usually glucan, fructan, xylan, mannan or galactan, etc., or two or more A polymer of monosaccharides. The branched-chain structures of polysaccharides exhibit great diversity. There are usually a large number of hydroxyl groups in the structure of plant polysaccharides, which have good hydration ability through hydrogen bonds. In addition, polar groups such as carboxyl groups of plant polysaccharides can also combine with water molecules through hydrogen bonds. Therefore, most plant polysaccharides have the properties of hygroscopicity and moisture retention. Plant polysaccharides have been widely used in various cosmetics as humectants. The moisturizing ability of plant polysaccharides is mainly affected by their sugar base structure, composition and molecular weight. The polysaccharides of many plant extracts can improve the moisturizing effect of the skin even at low concentrations, and can reduce water loss. β-glucan is a class of macromolecular cell wall polysaccharides widely present in plants and fungi, composed of β-glycosidic linkages of glucose groups. β-glucan is an effective moisturizing ingredient in cosmetic formulations, which can relieve dry skin and atopic diseases, and reduce itching caused by bacterial infections. β-glucans from different sources have different glycosidic bonds and their ratios and different three-dimensional structures, etc., which make β-glucans have different properties and biological activities, such as promoting wound healing, anti-inflammatory and anti-allergic. Oat β-glucan is composed of glucose groups connected by β-1,4 and 1,3 glycosidic bonds. The mixed chain structure of oat β-glucan destroys the uniform structure of β-D-glucan, making Oat β-glucan has good water solubility and moisture retention; while high molecular weight oat β-glucan has high viscosity. Aloe vera extract is a moisturizing raw material widely used in cosmetics. Many moisturizing cosmetics contain aloe vera extract. The main active ingredient of aloe extract is aloe polysaccharide. In addition to its good moisturizing effect, aloe polysaccharide has certain viscosity and gel properties, and it also has a good effect on skin wound healing and dry skin repair ; In addition, aloe polysaccharides also have certain effects on atopic dermatitis. The polysaccharides in cactus extract are composed of neutral polysaccharides, acid polysaccharides and acid glycoproteins. Cactus polysaccharides can not only hydrate, absorb and maintain skin moisture, but also have anti-inflammatory and wound healing effects. Most of the water-soluble plant polysaccharides, such as astragalus polysaccharides, licorice polysaccharides, dendrobium polysaccharides and fire ginseng polysaccharides, have good hydration and water absorption characteristics, and have good moisturizing and film-forming properties. Moisturizing, etc. have a very good effect, but also have antioxidant activity and other effects. There are also a large number of polysaccharides in seaweed, and the types of polysaccharides in different seaweeds are also different. Many seaweed polysaccharides have good hydration and hygroscopicity and the ability to retain water. Low-molecular-weight polysaccharides from some macroalgae exhibit a high ability to absorb and retain water compared to hyaluronic acid. Alginic acid is a polysaccharide from brown algae. Alginic acid can be used not only as a moisturizer, but also as a stabilizer and gelling agent in cosmetics. Alginic acid can quickly absorb water, and can also form a protective moisturizing complex through ion-ion interaction. It has good hygroscopic and hydrating properties, thereby helping to increase skin moisture and improve skin elasticity. In the presence of divalent cations, alginate has good gel properties and ion chelation; in the mask formulated with alginate, alginate forms a flexible film with better adsorption to the skin. In addition, algae extracts such as Rhizoctonia solifolia extracts have a moisturizing effect similar to hyaluronic acid, and the moisturizing effect is good and long-lasting; fucoidan improves skin elasticity through hydration; hydroxyl groups in sargassum polysaccharides and water form The intermolecular hydrogen bond promotes its water absorption,
