Objectives : Antioxidant, Anticancer and Antibacterial Activities of Naesohwangryntang and its composition oriental medicines. Methods : We were experimented anti-oxidation effect and growth inhibition ability on cancer cells and antibacterial activity on various kinds of bacteria of skin. Results : The results were obtained as follows : Electron donating ability(EDA) of water extract Naesohwangryntang and ethanol extract Naesohwangryntang was 60% and 70% at 1000 ppm concentration. In the test of SOD-like activity, ethanol extract showed more activity with 27.4% in 700 ppm, while water extract was low in 19.6%. Clear zones formed by sample against the human skin-resident microflora indicated that anti-microbial activity of ethanol extract Naesohwangryntang was higher than that of water extract Naesohwangryntang. The growth inhibition rates of each sample on lung-cancer(A549), at 1000 ppm cancer cell was over 40%. The growth inhibition rate of the each sample melanoma-cancer(B16F10, G361), at 1000 ppm was over 80%. Conclusions : The results indicated that, ethanol extract which is superior in its anti-oxidation and antibacterial effect is useful to be applied in cosmetic industry.
