1. Introduction of Quercetin Supplement
Quercetin is widely present in the stem bark, flowers, leaves, buds, seeds, and fruits of many plants, mostly in the form of glycosides, such as rutin, quercetin, hypericin, etc., and quercetin can be obtained by the acid hydrolysis cortex. Among them, the content is higher in the stems and leaves of buckwheat, sea buckthorn, hawthorn and onion. Quercetin is also found in many foods, such as onions, shallots, asparagus, cabbage, mustard greens, green peppers, endive, grapefruit, lettuce, hawthorn, apples, mangoes, plums, radishes, blackcurrants, potatoes, and spinach. . In addition, about 100 kinds of medicinal plants (such as Sophora japonica, Arborvitae, Galangal, Coltsfoot, Mulberry, Panax notoginseng, Ginkgo, elderberry, etc.) contain this ingredient. The preparation methods of quercetin include extraction and separation, acid hydrolysis, and enzymatic transformation, among which enzymatic transformation is the most practical. Since the content of quercetin in plants is only a few thousandths to a few thousandths, and the extraction and separation are difficult and the cost is high, it is not practical to extract quercetin directly from plants. However, when analyzing, identifying flavonoids or preparing analytically pure samples, quercetin extraction and separation techniques are used.
