Abstract: Composition, methods of synthesizing trans-arachidin-3; and, methods of use as a dietary supplement, food additive, pharmaceutical, nutraceutical, cosmeceutical, and antioxidant. The methods of production entail organic syntheses using primary alkylamines or primary hydroxyalkyl amines, or carboxy amines (amino acids) with natural carboxylic acids (acetic acid) as catalysts to react isovaleraldehye with trans-resveratrol. The synthesis is carried out in organic solvent, which is composed of an azeotropic mixture comprising toluene with pyridine, n-butanol, n-propanol, 2-propanol, 2-methyl-1-propanol, or other alcohols that form an azeotrope with toluene. The final product is purified and analyzed for the amount of trans-arachidin-3, such as via HPLC, IR, column chromatography, and high-performance counter-current chromatography.
