Natural Quercetin Powder

Basic introduction

Natural Quercetin Powder, also known as quercetin, is soluble in acetic acid, and its alkaline aqueous solution is yellow. our factory use Sophora Japonica flowers as raw materials to extract quercetin.It is almost insoluble in water, and its ethanol solution tastes very bitter. It can be used as a medicine, and has good expectorant and cough-relieving effects, and has a certain antiasthmatic effect. In addition, it can also lower blood pressure, enhance capillary resistance, reduce capillary fragility, lower blood lipids, dilate coronary arteries, and increase coronary blood flow. It is used to treat chronic bronchitis. It also has an auxiliary therapeutic effect on patients with coronary heart disease and hypertension.

Source and extraction

Natural quercetin powder mainly comes from a variety of plants, such as Sophora japonica, Quercus genus plants of Fagaceae, and Onion of Liliaceae. Its extraction process usually involves grinding the plant material, extracting with an appropriate solvent, and then purifying it. For example, rutin can be extracted from Sophora japonica extract, and then quercetin can be obtained by alkali extraction, acid precipitation, purification, and hydrolysis. In addition, quercetin can also be obtained by hydrolysis of other flavonoids such as rutin and quercetin.

Biological Properties

One of the most well-known flavonoids, quercetin, has long been a part of the human diet. Numerous health advantages, including antioxidant, anti-inflammatory, antiviral, and anticancer properties, as well as the ability to relieve several cardiovascular illnesses, have been widely linked to the usage of quercetin (i.e., heart disease, hypertension, and high blood cholesterol). However, quercetin’s uses are severely constrained by its poor water solubility, chemical instability, and limited bioavailability. Its stability, effectiveness, and bioavailability can be increased using delivery methods. This chapter included quercetin’s biological activity, chemical stability, metabolism, and toxicity as well as several quercetin administration methods. In the human body, quercetin that has been digested via the mouth, small intestine, liver, and kidneys is glucuronidated, sulfated, or methylated. Numerous elements, including heat, pH, and metal ions, may have an impact on the chemical stability (including oxidation and degradation) of quercetin during food preparation and storage. The use of delivery technologies, such as lipid-based carriers, nanoparticles (NPs), inclusion complexes, micelles, and conjugate-based encapsulation, has the potential to increase the stability and bioavailability of quercetin and, consequently, its health advantages. Every delivery system has a different set of benefits and drawbacks, therefore choosing one over another should be dependent on the application domains. In the future, it may also be necessary to investigate natural, food-grade substances as the primary components of quercetin delivery methods.

Natural Quercetin Powder Manufacture Flow Chart

Function

Antioxidant effect: Quercetin has a strong antioxidant capacity, which can remove free radicals in the body, slow down cell aging, and protect cells from oxidative damage. Studies have shown that quercetin can inhibit lipid peroxidation, reduce glutathione consumption, and increase the activity of antioxidant enzymes.
Anti-inflammatory effect:It can inhibit inflammatory reactions and relieve inflammatory symptoms. It can inhibit neutrophils from gathering at the site of inflammatory reactions and reduce the release of inflammatory factors. It is helpful for the treatment of inflammatory diseases such as muscle strain, rheumatoid arthritis, and acne.
Cardiovascular protection: It can dilate blood vessels, lower blood pressure, prevent and treat coronary heart disease, inhibit thrombosis, and protect cardiovascular health. It can also improve endothelial function, reduce myocardial hypertrophy, and inhibit the proliferation and hypertrophy of vascular smooth muscle cells.
Hypoglycemic and lipid-lowering effects: It can promote the production of glycogen in the liver and lower blood sugar levels. It has an auxiliary therapeutic effect on people with diabetes or abnormal blood sugar levels. At the same time, it can inhibit the formation of fat cells, lower blood lipid levels such as cholesterol and low-density lipoprotein, and help prevent and treat hyperlipidemia.6.Other potential benefits

Here are several other potential benefits of Pure Quercetin:

· May help combat aging. Test-tube and animal research suggestsTrusted Source that quercetin may help rejuvenate or eliminate aging cells and reduce markers of aging. However, more human research is needed.

· May aid exercise performance. A reviewTrusted Source of 11 human studies found that taking quercetin may slightly improve endurance exercise performance.

· May aid blood sugar control. Human and animal researchTrusted Source indicates that the compound may reduce fasting blood sugar levels and protect against complications of diabetes.
