Physicochemical properties and antioxidative activities of Omija(Schizandra chinensis


© 2013 The Korean Society for Biotechnology and Bioengineering Abstract: This research was to investigate physicochemical properties and antioxidative activities of rapeseed meal for the development of functional cosmetic material. Seventeen kinds of amino acid at rapeseed meal were found and glutamic acid concentration was significantly the highest (28.4 mg/g), fol-lowed by glycine, proline, arginine, isoleucine, and aspartic acid. Among various vitamins, cloline content was the high-est (459.1 mg/kg), followed by niacin, tocopherol, and pan-tothenic acid. Among various fatty acids of rapeseed meal, oleic acid was the highest (36.7%), followed by linoleic acid and linolenic acid. DPPH radical scavenging activities of methanol and acetone extract of rapeseed meal at 2.0 mg/mL were 80.4 and 78.9%, respectively. The methanol and ace-tone extracts of rapeseed meal were a stable at the range o
