ABSTRACT
Three types of Korean black raspberry wine were produced via alcoholic fermentation from juice, juice-pulp, and juice-pulp-seed, respectively. These wines were compared in terms of their anti-inflammatory activities and polyphenol contents. The total content of polyphenol compounds in wines was increased by 22.4% after supplementation with pulp and by 56.7% after supplementation with both pulp and seed. The reduction rate of NO evolution was highest in the order juice-pulp-seed wine, juice-pulp wine, and juice wine. Addition of the juice-pulp-seed wine at a level of 62.5-500 mg/L decreased the NO evolution rate by 40.5-94.2%. Eight fractions were obtained from juice-pulp-seed wine via ethyl acetate extraction and silica gel chromatography. Of these, the AF fraction, which exhibited the highest in vitro anti-inflammatory activity, exerted inhibitory effects on ear edema, writhing response, and vein membrane vascular permeability in mice. 3,4-Dihydroxybenzoic acid accounted for 37.6% of the total polyphenol content in the AF fraction.
