ケルセチン

の紹介 ケルセチン ：

ケルセチン is extracted from sophora japonica bud. Quercetin is green yellow powder with bitter taste, slightly soluble in water, easily soluble in alkaline solvent.

Usually quercetin refers to quercetin dihydrate. Moisture of quercetin dihydrate is 8%-12%, while it is less than 4% for quercetin anhydrous. The crystal water in the molecules of quercetin anhydrous has been removed.

Quercetin is a bioflavonoid obtained from diverse sources, including apples, buckwheat, onions, and citrus fruits.

Can Quercetin Treat COVID-19?

Quercetin has been shown by researchers to be a powerful immune booster and broad-spectrum antiviral substance. Therefore, it may help prevent and treat COVID-19 infection.

According to a 2016 study in the journal Nutrients, quercetin’s mechanism of action involves inhibiting lipopolysaccharide (LPS)-induced secretion of tumor necrosis factor alpha (TNF-α) from macrophages.

TNF-α is a cytokine involved in systemic inflammation and is secreted by activated macrophages, a type of immune cell that digest foreign substances, microorganisms, and other harmful or damaged components. Quercetin’s role and efficacy also regulates the influx of calcium ions into cells, thereby inhibiting the release of pro-inflammatory cytokines and histamine.

Quercetin also stabilizes mast cells and “can directly modulate fundamental functional properties of immune cells,” according to the paper, so it can downregulate or inhibit many inflammatory pathways and functions, thereby “inhibiting a broad range of molecular targets at the micromolar level.” concentration range”
