Quercetin is a phytochemical that is part of the coloring found in the skins of apples and red onions.Quercetin may

expel phlegm and arrest oughing, it can also be used as antiasthmatic. Quercetin has anticancer activity, inhibits PI3-

kinase activity and slightly inhibits PIP Kinase activity, reduces cancer cell growth via type II estrogen receptors.

 

Quercetin may inhibit histamine release from basophils and mast cells.Quercetin may control the spread of certain

viruses within the body. Quercetin may help reduce tissue destruction. Quercetin may also be beneficial in the

treatment of dysentery, gout, and psoriasis.

Function & Application 

1. Applied in pharmaceutical industry: Some medicine with bromelain like throat tablet can diminish inflammation,

facilitate digestion and improve immunological competence.So it can be applied in examination, treatment of gynecopathy,

glaucoma and inset bitten.

 

2. Applied in food industry: It can be applied in hydrolyzing protein of plants and animals, so it can be used in the meat

tenderizer,wine clarifier,stabilizer of noodle,health foods and soy sauce brewing etc. It can also improve the nutritional value.
