  Product Sophora japonica Extract Botanical Name Sophora japonica Part Used Seed Specification Quercetin 98% UV / 95% HPLC Appearance Yellow Powder Brand Name 3WBE What is Quercetin produced in HuNan 3W Botanical Extract Inc .? Quercetin, a flavonol, is a flavonoid, in other words, a plant pigment with a molecular structure like or derived from flavone. It is found in fruits, vegetables, leaves and grains. It can be used as an ingredient in supplements, beverages, or foods. Where will HuNan 3W Botanical Extract’s Quercetin used to? Antiviral Hyperoside (which is the 3-O-galactoside of quercetin) is a strong inhibitor of HBsAg and HBeAg secretion in 2.2.15 cells. Quercitrin and myricetin 3-O-beta-D-galactopyranoside inhibit HIV-1 reverse transcriptase, all with IC50 values of 60 μM. Quercetin can also inhibit reverse transcriptase, part of the replication process of retroviruses.The therapeutic relevance of this inhibition has not been established. Application of HuNan 3W Botanical Extract’s Quercetin Several laboratory studies show quercetin may have anti-inflammatory properties,and it is being investigated for a wide range of potential health benefits. Quercetin has been reported to be of use in alleviating symptoms of pollinosis.[34] An enzymatically modified derivative was found to alleviate ocular but not nasal symptoms of pollinosis. Studies done in test tubes have shown quercetin may prevent immune cells from releasing histamines which might influence symptoms of allergies. A study with rats showed that quercetin effectively reduced immediate-release niacin (vitamin B3) flush, in part by means of reducing prostaglandin D2 production. A pilot clinical study of four humans gave preliminary data supporting this.
