1)For the development of functional food and cosmetics using the hot water extract of Undaria pinnatifida, the concentrations of vitamin, amino acid and element and activities of antioxidant and nitrite scavenging were investigated. The results are shown as follows: Vitamin C and E concentrations were 0.301 and 0.11 mg/100 g, respectively. Mineral concentrations were an order of Ca > Mg > K > Fe. The concentrations of total amino acids were an order of Glu > Ala > Val > Leu > Gly > Pro. Total phenol concentration and DPPH radical scavenging activity were increased with the increase of the concentration of extract. Especially, when the extract concentrationwas increased from 1.0 to 10.0 mg/mL, the total phenol concentration was increased from 0.043 to 0.125 OD 725 nm. DPPH radical scavenging activity at 50 mg/mL was 70.1%. The antioxidant activity of extract was stable in range of 80 to 140℃ and pH 3-9. The nitrite scavenging activity was increased with the decreaseof pH and the increase of it’s extract concentration. Especially, it was 83.4% at 50 mg/mL (pH 1.2). These results showed that the hot water extract of U. pinnatifida can be applied to functional food and cosmetics.
