Poudre de quercétine Dihydrate

Qu’est-ce que la poudre de quercétine Dihydrate?

La quercétine est un composé flavonoïde largement distribué dans le règne végétal et se trouve dans de nombreux légumes, fruits et herbes. La quercétine Dihydrate, également connue sous le nom de paclitaxel et de sapin de Douglas, est un composé dihydroflavonol qui appartient à la famille de la vitamine P. La quercétine dihydrate, comme son nom l’indique, contient deux eaux cristallines dans sa formule structurale. La quercétine anhydre élimine les deux eaux cristallines dans la formule structurale de la quercétine dihydrate, et la dihydroquercétine est la forme réduite de la quercétine, c’est-à-dire le produit de l’hydrogénation de la double liaison à la position 2,3 dans le noyau parent de la quercétine.

La quercétine est dérivée des boutons floraux de la légumineuse Sophora japonica L; La dihydroquercétine est obtenue à partir de deux sources, l’une en hydrogénant la double liaison en position 2,3 dans le noyau parent de la quercétine, l’autre en l’extrayant des segments du mélèze. La quercétine dihydrate est une substance chimique phytochimique ou végétale utilisée comme ingrédient dans les suppléments, les boissons ou les aliments. Il pourrait avoir des propriétés anti-inflammatoires et antioxydantes dans plusieurs études et est à l’étude pour un large éventail d’avantages potentiels pour la santé.

La poudre dihydratée de quercétine fournie par la technologie Green Spring est extraite des boutons floraux de Sophora japonica L, une plante légumineuse, et est disponible dans une variété de spécifications Avec le contenu élevé et la qualité stable. Des matières premières aux produits, Green Spring&#La production est contrôlée et traçable, et les tests de divers polluants répondent aux normes mondiales.

Benefits:

Anti-Inflammatory Effects

Quercetin reduces the release of inflammatory mediators by regulating NF-κB and inhibiting TNF-α production and gene expression as well as the expression of inflammatory mediator genes. The antioxidant effect of quercetin also helps to reduce the inflammatory response.

Antimicrobial

Quercetin has a broad-spectrum antibacterial property, and its antibacterial effect against Gram-negative bacteria is stronger than that against Gram-positive bacteria. Qin Xiaorong et al. showed that quercetin has the best antibacterial effect on Staphylococcus aureus, and the second-best antibacterial effect on Bacillus coli, Bacillus thuringiensis, Bacillus subtilis, and Pseudomonas aeruginosa.

Protecting the Skin

Zhu Yu et al. found that the number of melanocytes increased significantly after the topical application of quercetin to the guinea pig epidermis, dihydrogen has a color-enhancing effect on the dorsal skin of brown guinea pigs and has the function of promoting melanocyte proliferation and melanin synthesis. In addition, quercetin also interfered with collagen transcription and combined with radiation significantly reduced collagen synthesis in keloid fibroblasts cultured in vitro.

Protects the Cardiovascular System

Dihydroquercetin can inhibit the release of endothelin and reduce the tension of blood vessels, thus lowering blood pressure. Quercetin can significantly inhibit the increase of total protein content of cardiomyocytes caused by angiotensin II, can significantly increase SOD activity, reduce MDA content, and have an obvious preventive effect on cardiomyocyte hypertrophy.

Helps Lower Blood Pressure

Often associated with cardiovascular health, high blood pressure affects millions of people worldwide each year. a report published in the Journal of Nutrition by Edward RL, PhD, Department of Nutrition at the University of Utah Quercetin has demonstrated the ability to lower blood pressure and eliminate the complications often associated with the disease. As a vasodilator, anti-inflammatory, and antioxidant, quercetin contributes to heart health.

Helps Relieve Asthma

Quercetin acts as a bronchodilator, reducing the amount of inflammatory or allergic reaction chemicals in the body. As a result, a 2013 report published in the Journal of Nutrition states that it can reduce the severity of asthma attacks that react to these chemicals, and also reduce various forms of congestion unrelated to asthma.

Applications:

In the Food Field:

The US FDA approved quercetin (≥99.5%) processed and produced from natural products as a GRAS substance in 2010. In addition, in Japan and South Korea, quercetin is included in the categories of existing food additives and natural food additives, respectively. Quercetin Dihydrate was approved by the European Union in 2017 to be placed on the EU market as a novel food ingredient.

For Health Products:

Quercetin can increase immunity or prevent infections, it is a good expectorant, a cough suppressant, has some asthmatic effects, is used in the treatment of chronic bronchitis, and is used in health products.

In Pharmaceutical:

Recent studies have shown that quercetin also significantly inhibits platelet-derived growth factor-induced proliferation of pulmonary artery smooth muscle cells, which is important for the prevention and treatment of pulmonary hypertension. Quercetin Dihydrate powder has been used in the pharmaceutical industry for its many pharmacological properties including antiviral, anti-microbial, anti-inflammatory, anti-cancer, anti-oxidant, cardiovascular, and reproductive protection, and as an anti-obesity drug that may help prevent many chronic diseases.
