Quercetin is a kind of polyhydroxy flavonoids, which widely exists in flowers, leaves and fruits of plants. Quercetin has many biological activities and high medicinal value. Its known pharmacological effects include anti-cancer, anti-oxidation, anti-fibrosis, anti-inflammation and so on. New pharmacological effects have been found continuously, such as anti-aging, anti-depression and so on. At present, many studies on the pharmacological effects of quercetin are not yet mature, and the drugs with quercetin as the main component are relatively few, and have not been widely used in clinical treatment.
In addition to extensive anti-tumor effects, quercetin also has important antioxidant effects. In the process of oxidative stress, excessive production of high active molecules such as reactive oxygen species (ROS) and reactive nitrogen free radicals (ROS) leads to imbalance between oxidation system and antioxidant system, which eventually leads to tissue damage and disease development. Free radicals can not only cause or aggravate diseases such as tumors, stroke and heart disease, but also have a close relationship with free radical damage in the aging process.
In recent years, the anti-fibrosis studies of quercetin have shown that quercetin has anti-hepatic fibrosis, pulmonary fibrosis, keloid hyperplasia and glaucoma filtering bleb scarring. The anti-fibrosis mechanisms include inhibiting fibroblast proliferation, inhibiting collagen synthesis, preventing oxidative damage, inhibiting angiogenesis and inducing cell apoptosis.
Quercetin can alleviate the inflammation caused by PMN activation by preexcitator and achieve anti-inflammatory effect. In addition, quercetin also showed good anti-inflammatory effects in the experimental study of the treatment of non-bacterial prostatitis and acute gouty arthritis.
It has been found that quercetin has anti-bacterial, anti-aging, anti-depression, anti-leukemia, anti-diabetes and other pharmacological effects. Quercetin has broad-spectrum antimicrobial activity, and its antimicrobial activity to Gram-negative bacteria is stronger than that of Gram-positive bacteria.
