v-innovate Technologies provides high performance liquid chromatography-mass spectrometry (HPLC-MS/MS) based methods for quercetin analysis, which provides sufficient stability, sensitivity and high resolution for identification and quantification of quercetin. This approach has the advantages of simple, stable, fast, accurate, specific and reproducible, which can help researchers to analyze quercetin effectively.
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.
v-innovate Technologies 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.
Our newly developed sample preprocessing method provides safety, environmental protection, rapidness, effectiveness, and the average recovery rate is above 90%. Sample preprocessing at v-innovate Technologies complies with the in-house standard operation procedures (SOP), ensuring maximized homogeneity between samples.
