Most of the cells, specially in the skin, free radicals and reactive oxygen species induced aging, accompanying with diseases. The pinaceae family is very familiar plant with Korean spirit. However, those plants were not estimated for natural products in manufactural process. We employed 4 different plants, Pinus koraienis S et Z. Pinus banksiana LAMBERT. Pinus rigida MILL. Pinus densiflora S. et Z. in pinceae family. The ethanol extracts were prepared for three different parts of plant, wood, bark and leaf, respectively. In this study, we carried out free radical and superoxide radical scavenging assay to investigate the anti-oxidative activity The bark and leaf part of plants showed similar anti-oxidant effect. L-ascorbic acid and alpha-tocopherol at 10{mu}g/mL. Also we tried to investigate inhibitory effects of elastase activity in in vitro experiments on pinaceae plant extract as a matters for functional cosmetics. Among those plants, the bark of Pinus rigida MILL. and Pinus densiflora S. et Z. showed inhibitory effect. The cell viability was evaluated with MTT assay. The potential relationship was shown between the cell viability and anti-oxidant effect because the anti-oxidant effects were positively correlated wvith the cell growth in MTT assay. As the results in our experiments, we expect the potential activities of pinaceae as a material of functional cosmetics.
