What is Quercetin?

Quercetin is a widely distributed flavonol compound with a variety of biological activities in the plant kingdom. Quercetin is widely found in the stem bark, flowers, leaves, buds, seeds and fruits of many plants, mostly in the form of glycosides, such as rutin, quercetin, hyperoside. Quercetin can be obtained by acid hydrolysis. Among them, quercetin content is higher in the stem and leaves of buckwheat, sea buckthorn, hawthorn and onion. Quercetin fights free radicals, complexes or traps free radicals to prevent lipid peroxidation in the body. Quercetin can directly inhibit tumors and effectively play a role in cancer prevention and anticancer. Quercetin also has strong biological activity in antibacterial, anti-inflammatory, anti-allergic and prevention of diabetes complications. In addition, quercetin has the functions of lowering blood pressure, enhancing capillary resistance, reducing capillary fragility, lowering blood lipids, dilating coronary arteries and increasing coronary blood flow. Quercetin is non-toxic, so it has great significance for the treatment and prevention of cancer, aging and cardiovascular diseases, which has great development value.

Creative Proteomics provides the simple, rapid, accurate, affordable and highly automated analytical method and equipment to analyse quercetin. High performance liquid chromatography-mass spectrometry (HPLC-MS/MS) can solve some of the problems associated with quercetin analysis. Improved extraction and purification steps can also increase the sensitivity of the analytical method.

Applications of Quercetin Analysis

Dietary assessment: Analysis of quercetin content in various foods provides valuable information for dietary assessment and recommendations.

Pharmacokinetics: Monitoring the absorption, distribution, metabolism and excretion of quercetin in the body helps to understand its pharmacokinetic properties and optimize its therapeutic use.

Biomarker discovery: Identification of quercetin metabolites in biological samples as potential biomarkers for various diseases and conditions.

Drug discovery: screening natural products for quercetin-like compounds with therapeutic potential, or evaluating the efficacy of quercetin-like drugs in preclinical and clinical studies.

Toxicology: To assess the safety of quercetin and its derivatives by identifying and quantifying any potentially toxic metabolites.
