Physiological activity and antioxidative activity of Maesangi(Capsosiphon fulvescens) extracts with distilled water or 95% ethanol were investigated. For the evaluation of physiological and antioxidative activities, some evaluation assay methods such as measurement of Hunter color value, chlorophyll a/b value, total phenolics, reducing power and thiobarbituric acid(TBA) value of soybean oil were used. Proximate composition and mineral contents of Masaengi were orders of crude protein>crude fiber>moisture>crude ash>crude lipid, and K>Ca>Mg>Na>P>Fe>Zn, respectively. In ethanol extract, the content of total phenolic compounds in Maesangi was determined to half times of that in Dasima(Laminaria). The reducing power of Maesangi-ehtanol extract was about 5 % of vitamin C and was lower than that of Dasima-ethanol extract. The TBA value of Maesangi-ethanol extract on soybean oil oxidation was about 47 % and 68.4 % to control in three and eight days oxidation, respectively. But TBA value difference was not observed significantly with the dosage below 5mL of ethanol extract.

Objectives : The aim of this study is to report the effect of Capsosiphon fulvescens(Maesangi) extract(MSE) on contact dermatitis(CD). Methods : CD induced by Dermatophagoides farinae body(Dfb) in NC/Nga mice. 4% sodium dodecyl sulfate(SDS) $150{\mu}l$ and Dfb(10mg/ml) ointment 100mg were topically treated twice a week for four weeks. MSE 200 mg/kg was topically treated every 4weeks. Every week, we examined the skin lesions, weight of spleen and lymph node, epidermal thickness, production of Tumor necrosis factor-alpha($TNF-{\alpha}$) and interleukin-6(IL-6). Results : MSE reduced features of Dfb-induced skin lesions, weight of spleen and production of $TNF-{\alpha}$. MSE significantly reduced weight of lymph node, epidermal thickness, number of mast cells and production of IL-6. Conclusions : MSE may have a potential therapeutic effects for CD by suppressing allergic inflammation.
