What is quercetin powder?
Quercetin, also known as quercetin, is a flavonol compound widely distributed in the plant kingdom and has a variety of biological activities. Its chemical formula is C15H10O7. 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, etc. Quercetin can be obtained by acid hydrolysis Cortin. Among them, the content is higher in buckwheat stems and leaves, sea buckthorn, hawthorn, and onions. Quercetin is also found in many foods, such as onions, chives, asparagus, cabbage, mustard greens, green peppers, chicory, grapefruit, lettuce, hawthorn, apples, mangoes, plums, radishes, black currants, potatoes and spinach. . In addition, about 100 kinds of medicinal plants (such as Sophora japonica, Platycladus orientalis, galangal, coltsfoot, loranth, Panax notoginseng, ginkgo, elderberry, etc.) contain this ingredient.

Preparation method of quercetin.
Natural extraction and isolation
Since the content of quercetin in plants is only a few thousandths to a few thousandths, and its extraction and separation is difficult and costly, extracting quercetin directly from plants is not practical in production. However, when analyzing and identifying flavonoids or preparing analytically pure samples, quercetin extraction and separation technology must be used.
acid hydrolysis
The rutin (rutin) of quercetin is widely distributed in nature and has high content. For example, the content in sophora rice is as high as more than 20%. Rutin is first extracted from Sophora japonica and then acid hydrolyzed to produce quercetin. This method is feasible for production.
The main extraction methods of rutin include alkali extraction and acid precipitation, organic solvent extraction, and dipping. Among them, the alkali extraction and acid precipitation method is the most practical. Choose a 0.05% NaOH solution and boil it for 20 minutes, filter it while it is hot, and extract it 4 times with the same method to obtain an alkali aqueous solution of rutin. Add acid to precipitate it. After filtering, add acid to hydrolyze it to obtain water-insoluble quercetin. Filter , washed with water and dried to obtain quercetin solid.
enzyme conversion method
Enzymatic hydrolysis of rutin is used to prepare a large amount of quercetin monomer, which is less abundant in plants. The operation is simple and safe. The whole process is economical and practical. The output is large and suitable for industrial production. The purity of the product is >90%, which can meet the needs of food and clinical applications. . Therefore, enzymatic conversion is undoubtedly a promising preparation method.
Most quercetin production still relies on rutin, and sophora rice, the largest source of rutin, is a seasonal crop, which means that quercetin has natural price fluctuations.
