The possibility of obtaining quercetin (a natural antioxidant) from buds of Sophora
japonica
L. using subcritical water, which acts as a solvent and a reagent simultaneously
was studied. The suggested approach avoids the use of expensive and toxic organic
solvents, does not require separate extraction and hydrolysis steps and simplifies the
purification of the product. A 13-fold reduction in treatment time was achieved compared
with the traditional procedure to obtain high yield of quercetin. The loss of the target
product in the production of the dried extract was reduced.
