Functional cosmetics in Korea are defined as the products which have anti-wrinkle, and/or whitening, and/or sun-screen effects. Recently, various efforts are being made to develop functional cosmetic ingredients from natural resources. In our laboratory, we are searching for the natural products having anti-aging or whiteningactivities from plants growing in Jeju Island, Korea. We have screened anti-tyrosinase, anti-elastase and DPPH radical scavenging
activities using the ethanol extracts of plants collected in Jeju. From the activity tests, some plant species such as Distylium racemosum, Quercus glauca, Maakia fauriei, Cornus kousa, Sasa quelpaertensis were chosen for the further phytochemical study to find out bioactive
components. In this presentation, we will disclose our results on the biological activities as well as isolation and identification of some natural products of interest.
