This research was performed to determine the proximate compositions, mineral contents, alginic acid, antioxidative activities and amino acids of sea mustards (Miyeok: Undaria pinnatifida) collected from Gijang and Wando area. Ash content was higher in Gijang samples, whereas carbohydrate and moisture were higher in Wando Sil Miyeok. General compositions of dried sea mustard showed different contents as manufacture’s company and places. The major free amino acids were hydroxyproline, alanine, glutamic acid and asparagine in Gijang samples. Both Gijang and Wando Sil Miyeok showed lower contents comparing with Gijang Gadak Miyeok. Major mineral content was Na, K, Ca, Mg and P, and especially, Na and K were the most abundant in both Gijang and Wando sea mustards. Alginic acid content was almost similar in both sea mustards. Antioxidative activity of methanol extract of sea mustards was measured by using DPPH radical scavenging and SOD-like activity. DPPH radical scavenging activity was 45.5% (40μg/mL)in Gijang Gadak Miyeok and 37.0% and 26.0%(40μg/mL ) in Gijang and Wando Sil Miyok, respectively. SOD-like activity of Gijang and Wando Sil Miyok was 63% and 71%(40μg/mL) , respectively. These results show that biological activities depend on Miyeok manufacture’s process. When stimulated macrophages RAW264.7 cells with lipopolysaccharide (LPS), inhibition of NO production in Gijang Sil Miyeok (44.2%) was 9% high comparing with that of Wando Sil Miyeok (35.7%).
