1)Contents of amino acids, vitamins, and minerals as well as its antioxidant activitiy of Laminaria japonica water extract have been analyzed for preparation of functional foods and cosmetic products. From the analysis of total amino acids, eighteen kinds of amino acids were found in the water extract of Laminaria japonica. Among total amino acids, the order of contents was glutamic acid (2.07 mg/g), alanine (0.51 mg/g), aspartic acid (0.44 mg/g), glycine (0.34 mg/g), and valine (0.34 mg/g). In case of free amino acids, glutamic acid (0.95 mg/g), prolin (0.54 mg/g), aspartic acid (0.44 mg/g), leucine (0.07 mg/g), and phenylalanine (0.07 mg/g) were dominant compositions. Vitamin E was only detected in water extract of Laminaria japonica. The mineral contents were as follows: K 752.60 mg, Na 259.20 mg, Ca 80.20 mg, P 29.50 mg, and Fe 8.32 mg based on 100 g Laminaria japonica water extract. The nitrite scavenging activity of the extract were gradually increased with the extracts contents to 86.2% at concentration of 100 mg/mL and DPPH radical scavenging activity of the extracts were 86.4% at concentration of 50 mg/mL.
