Seaweed is consumed as nutritive food materials in many Asian countries such as Japan, Korea and China. In the present study, we analyzed proximate composition of two Korean seaweeds Sargassum horneri and Ecklonia cava. Crude protein content of S. horneri and E. cava were 8.57% and 9.11%, whereas 1.03% and 1.40% of total lipid was found from S. horneri and E. cava. We used supercritical carbon dioxide (SC-CO2) with ethanol, methanol, acetone and hexane for the extraction process. The highest extraction yield was obtained from E. cava by SC-CO2 with ethanol and the value was 1.52 g/100 g DW. Further, fatty acid composition of S. horneri and E. cava by SC-CO2 with ethanol were analyzed. The total unsaturated fatty acid of S. horneri and E. cava samples were 59.95% and 17.79%, respectively. Important PUFA such as EPA and DHA were present in both samples. Total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity were found in both seaweed extracts with the highest concentration obtained from E. cava extracted by SC-CO2 with ethanol.
