Product Specific References
DIHYDROQUERCETIN is a key dihydroflavonol intermediate between FLAVONOLS and FLAVANOLIGNINS. An NADPH-dependent dihydroflavonol 4-reductase catalyses the formation of leucocyanidin (Flavan 3,4-diol) structure.

Dihydroquercetin, a yellowish crystalline pentahydroxy-flavanone, occurring in large quantities in Larix species, Douglas fir and Jeffrey pine barks, was found to be an effective antioxidant for lard, cottonseed oil, and butter oil. This compound imparts no taste and color to fats and oils and appears to be nontoxic. Dihydroquercetin is the non-nutrient antioxidant, relating to flavonoids, which occur in food and which may be significant in the overall antioxidative protection afforded by the diet. This benefit may be conferred in three main ways:
(1) As antioxidant in food during storage and in the gastrointestinal tract;
(2) As antioxidants in the human body;
(3) By providing protection in food against oxidation as well as acting as true antioxidant.
