実験手順

Working solution of 1% vanillin was prepared by dissolving 0.1 g of vanillin in 10 mL of 5 N HCl, whereas 5% dimethylaminocinnamaldehyde (DMACA) was prepared in methanol containing 5% H2SO4. Lyophilized extract for 100 mg of dry kernels was dissolved in 0.5 mL of vanillin or DMACA working solutions. Taxifolin and catechin each at a concentration of 100 ppm were used as reference compounds for color reactions. Because vanillin is catechin-specific and produces bright red color, no color is developed when it reacts with taxifolin. DMACA reacting with catechin produces dark greenish blue color, whereas reacting with taxifolin produces purple color.
