Quercetin Dihydrate Powder

What is Quercetin Dihydrate Powder?

Quercetin is a flavonoid compound widely distributed in the plant kingdom and is found in many vegetables, fruits, and herbs. Quercetin Dihydrate, also known as paclitaxel and Douglas fir, is a dihydroflavonol compound that belongs to the vitamin P family. Quercetin dihydrate, as its name implies, contains two crystalline waters in its structural formula. Quercetin anhydrous removes the two crystalline waters in the structural formula of quercetin dihydrate, and dihydroquercetin is the reduced form of quercetin, that is, the product of the hydrogenation of the double bond at the 2,3 position in the quercetin parent nucleus.

Quercetin is derived from the flower buds of the legume Sophora japonica L; dihydroquercetin is obtained from two sources, one by hydrogenating the double bond at the 2,3 position in the parent nucleus of quercetin, and the other by extracting it from the segments of the larch tree. Quercetin dihydrate is a phytochemical or plant chemical used as an ingredient in supplements, beverages, or foods. It may have anti-inflammatory and antioxidant properties in several studies and is being investigated for a wide range of potential health benefits.

Quercetin Dihydrate Powder supplied by Green Spring Technology is extracted from the flower buds of Sophora japonica L, a leguminous plant, and is available in a variety of specifications with high content and stable quality. From raw materials to products, Green Spring's production is controlled and traceable, and the testing of various pollutants meets global standards. The company is equipped with a perfect testing system for accurate testing of various indicators.

Specification: 

Regulation:

It conforms to EU regulations.

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.
