Basic Information
 

Introduction

Quercetin is a plant flavonol from the flavonoid group of polyphenols. It is found in many fruits, vegetables, leaves, seeds, and grains; capers, red onions and kale are common foods containing appreciable amounts of quercetin. Quercetin has a bitter flavor and is used as an ingredient in dietary supplements, beverages, and foods.

Physiological Activity

Inflammation
Some laboratory studies have shown that quercetin may have anti-inflammatory properties , and its potential curative effects are being studied. 

Pipin can alleviate the symptoms of hay fever.  One of its enzyme-modified derivatives was found to reduce the eye symptoms of hay fever. 

A study on mice showed that quercetin can effectively reduce flushing caused by immediate-release niacin, partly by reducing the production of prostaglandin D2.  Preliminary data from a four-person pilot clinical trial supports this view. 

Cancer
Laboratory in vitro cell studies have shown that pepitin can also be turned into a carcinogen, but this study did not report that it will increase the risk of cancer in animals or humans. 

The American Cancer Society stated that although pecortin "has been selected as an effective substance for many diseases including cancer," and "some early experimental results show that it has promising development, there is no reliable clinical evidence for pecoretin. It can prevent or treat human cancer." Adequate intake of fruits and vegetables may reduce the risk of cancer , and quercetin is one of many possible sources of action that has been studied.

In animal experiments, it has been speculated that pepitin may reduce the risk of certain cancers.  An eight-year study found that three flavonoids-kaempferol, pepin and myricetin-can reduce the risk of pancreatic cancer in smokers. 

The combination of pepitin and ultrasound can inhibit skin cancer and prostate cancer cells cultured in vitro. 

Metabolism
Lopin has been shown to increase energy metabolism in rats, but only in the short term (less than 8 weeks).  The effect of pecorin on exercise tolerance in mice is related to the increase of mitochondrial biosynthesis.  Oral administration of 12.5 to 25 mg/kg of pepitin in mice can increase the gene expression of mitochondrial biomarkers and improve exercise tolerance. .

There have been preliminary studies on the safety and effectiveness of pepitin for glucose absorption in sarcoidosis, asthma, obesity and diabetes. 

Some scholars have also claimed that pepitin can lower the blood pressure of patients with hypertension , and can reduce the level of low-density lipoprotein cholesterol in obese people. 

In vitro studies have shown that the combined application of pepitin and resveratrol can inhibit the production of fat cells.
