Quercetin is a polyphenolic flavonoid compound that is extensively found in nature, with its history dating back to 1936 when it was first isolated by Hungarian physiologist Albert Szent-Györgyi. The name Quercetin is derived from the Latin word "quercus" (oak tree), and it is discovered in many plants, including onions, apples, tea leaves, buckwheat, and various medicinal plants such as sophora japonica (Japanese pagoda tree).

Geographical Distribution

Quercetin is widely distributed in edible plants around the world, particularly in higher concentrations in some plants from Europe, Asia, and North America. For instance, in China, quercetin can be extracted from traditional medicinal herbs such as sophora japonica and taxillus chinensis (Chinese mistletoe).
