Omija (Schizandra chinmensis Baillon) grown widely in Korea has been used as a traditional drink and as an ingredient in herbal medicine. A determination of the proximate composition, organic acids and major anthocyanins in Omija was made. 1. The proximate composition of Omija showed water to be 84.2%, protein to be 1.1%, fats to be 0.9%, reducing sugars to be 10.9% and total anthocyanins to be 0.2% in terms of weight percent of fresh, ripe Omija 2. Gas chromatography showed citric acid(3.5%), malic acid(1.4%) and succinic acid(0.2%) to be the major organic acids of the fruit. 3. The anthocyanins, the major pigments present in Omija were separated and isolated into 3 fractions using column chromatograph on insoluble polyvinylpyrrolidone. The main anthocyanin was tentatively identified as peonodin 3-glucoside on the basis of its absorptive properties before and after treatments with acid and $AlCl_3$ in the UV and visible ranges.
