This study attempted to investigate the functionality of Dactylosiphon bullosus, Sporochnus radiciformis, and Zonaria diesingiana extracts among algae as cosmetic ingredients. For this, antioxidant experiments were performed. D. bullosus, S. radiciformis and Z. diesingiana extracts were prepared with a 70% ethanol concentration to measure antioxidant activities. In terms of DPPH radical scavenging activity, Z. diesingiana was the highest with 94.20±0.28%. In ABTS radical scavenging activity, Z. diesingiana was the highest with 96.26±0.98%. In terms of the total phenolic contents and NO radical scavenging activity, Z. diesingiana was the highest with 47.19±2.07 mg gallic acid/g and 92.87±1.79%, respectively. The above results show that Z. diesingiana extract has the greatest antioxidant activity, confirming its potential as a cosmetic ingredient.

Particulate matter is a major contribution of air pollution and detrimental to human health. The in vitro antioxidant activities of a brown seaweed, Sargassum horneri ethanol extract (SHE) against particulate matterinduced oxidative stress were investigated by measuring 1,1-diphenyl-2-picrylhydrazyl (DPPH) free-radical scavenging activity, hydrogen peroxide (H 2 O 2 ) scavenging activity, superoxide anion (O 2 Á-) inhibition, hydroxyl radical ( Á OH) scavenging activity, reducing power, and the metal ion-chelating effect. All in vitro antioxidant activities were increased as the concentration of SHE increased (0-1000 lg/mL). When treated with particulate matter at 0-1000 lg/mL, the DPPH free radical, and H 2 O 2 scavenging activities, reducing power, and metal ion-chelating abilities of SHE were significantly decreased (p \ 0.05).These results indicate that Sargassum horneri, which is a rich source of bioactive compounds, can be used as a natural source of antioxidants in the food industries.

This study was performed in order to investigate the functional components of 5 kinds of marine algae. We have collected 5 samples of marine algae, such as the sea mustard (Undaria pinnatifida), sea tangle (Laminaria iaponice), sea weed fusiforme (Hizikia fusiforme), green laver (Entetomotpha), laver (Phophyratenera), which have been harvested in Jeollanam-do. In order to examine the functional effects, 5 kinds of marine algae were extracted with hot water (80℃, 4 hr), ethanol and methanol (R.T., 4 hr), and subcritical water extract (SWE, 3 MPa, 90℃, 150℃, 210℃). A higher yield of extract was obtained through SWE method (3 MPa, 210℃) in all of the samples obtained. The highest total sugar content was 427.4 mg/g in green laver extracted with SWE (3 MPa, 210℃). The content of the SWE total phenolic compounds was higher than that of the water and solvent (methanol, ethanol) extracts. The anti-oxidative activities of the extracts from 5 kinds of marine algae were examined through the DPPH radical scavenging activity test. The SWE (3 MPa, 150℃ and 210℃) of the marine algae was the highest among all of the extracts. As per the results, the SWE of the marine algae contained more functional components and it had a higher antioxidant activity than those of the other extracts. The IC50 value of tyrosinase in seaweed fusiforme and laver were higher than those of the other samples. These results strongly support the possible use of marine algae as functional materials.Key words：marine algae, subcritical water extract, functional components, antioxidative activity 서 론
