Seaweeds, laver, sea mustard, kelp, and fusiformis, were prepared and investigated for its antioxidant and tyrosinase inhibition activities. The extracts yield, color, total phenolic contents, antioxidative activity, and tyrosinase inhibition activity of the extract samples were measured. Hunter Lightness values of laver, sea mustard, kelp, and fusiformis extracts were 82.88, 78.53, 83.04, and 78.11, respectively. The contents of total phenolic compounds of the seaweed extracts powder, laver, sea mustard, kelp, and fusiformis were 43.23, 11.59, 10.09, and 46.59 mg/g of sample, respectively. 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity of the fusiformis extract was shown to be the highest value compared with other seaweed extracts. 2,2"-azino-bis-3-ethylbenzo-thiazoline-6-sulfonic acid (ABTS) radical scavenging activities of laver, sea mustard, kelp, and fusiformis extracts were 258.00, 219.26, 95.77, and 1186.62 μmol trolox equivalence per gram, respectively, at the 1,000 ppm level. TBARS value of oil emulsion, samples without extracts was higher than those of the samples prepared with laver and sea mustard extracts. The inhibition rates (%) of the mushroom tyrosinase of laver, sea mustard, kelp, and fusiformis extracts powder were 25.93, 26.32, 24.76 and 20.24% at 1,000 ppm, respectively. The results indicated that laver, sea mustard, kelp and fusiformis extracts possess biological activities such as antioxidant activity and tyrosinase inhibition effect.
