Quercetin is a natural flavonoid extracted from the flower buds of Sophora japonica. It appears as a Yellow to yellow-green crystalline powder with a bitter taste, slightly soluble in water, and readily soluble in alkaline solutions.
This is the most widely used form, containing approximately 8%–12% moisture due to the presence of crystal water in its structure.
This form has less than 4% moisture content, as the crystal water has been removed, resulting in higher purity and stability.
- Sophora japonica (Pagoda Tree) buds - a major commercial source in Asia.
Commercial Quercetin powder is primarily produced via solvent extraction from plant materials, followed by purification.
Dried plant material is ground.
Using hot water, ethanol, or methanol, often with acid hydrolysis to convert quercetin glycosides (e.g., rutin) into the more active aglycone (quercetin) form.
Filtration, concentration, crystallization, and washing yield the crude powder. Further chromatographic purification is used for high-purity standards (>98%).
Exists in nature mainly as glycosides (bound to sugars like rutinose). Most commercial supplements provide the aglycone form, which is considered the bioactive form.
