Description
Quercetin Product Overview
Quercetin (C15H10O7) is a yellow crystalline powder that is practically insoluble in water. Commercial quercetin is usually the dihydrate, made from rutin extracted from the flower buds of Sophora japonica.
In addition, producers of nutritional products use it in capsules and tablets, often combined with vitamin C, bromelain or Resveratrol, within the regulations of each market. Similarly, food producers use it in functional foods and drinks, and cosmetic formulators use it as an antioxidant. Researchers also use it widely as a reference flavonoid.
Because its water solubility is low, producers sometimes use special formulations to improve dispersion. Related plant actives in our range include Green Tea Extract, Grape Seed Extract and Ascorbic Acid (Vitamin C).
