Pericarpium castaneae extracts have variously potent activities, such as anti-oxidative activity and free radical scavenging activity. in vivo and in vitro studies both indicate that pericarpium castaneae extracts acts as a free radical scavenger($IC_{50}:7.6{\mu}g/ml$) stronger than gallic acid($IC_{50}:12.5{\mu}g/ml$) and ellagic acid($IC_{50}:15{\mu}g/ml$) which could prevent cutaneous UV damages and skin aging. The extracts showed a good effect as a anti-oxidant($IC_{50}:50{\mu}g/ml$). It was shown that the appearance of wrinkle in human skin was reduced by topical application of pericarpium castaneae extracts. And the treatment of human skin with the extracts increased the elasticity and moisture of the skin. We investigated the effect of the pericarpium castaneae extracts on production of extracellular matrix using cultured A431 fibroblast cells. The results indicated that the extracts had no detectable effect on collagen synthesis. But synthesis of cell adhesion protein was increased by the extracts. The results suggest that increase of cell adhesion protein synthesis by pericarpium castaneae extracts has closely related to reduction of wrinkle in skin.
