The purpose of the present research was to investigate the physiological activities of the thermal treated eggplant on the skin. Five minute of thermal treatment at 100oC had the highest polyphenol content of eggplant. However, below and over 5 min of thermal treatment time, they did not increase. When water and ethanol extracts were used, the maximum DPPH radical scavenging activities were obtained, 66.3 and 62.8%, respectively. Among various extracts, the acetone extract gave the highest cosmetic activity. Especially, when acetone extract (15.0 mg/mL) was used, the maximum inhibition activities of tyrosinase, elastase, and collagenase were obtained, 83.4, 78.2 and 62.5%, respectively. These results suggest the anti-wrinkle and whitening and effects of acetone extract were excellent. Therefore, it is should be considered as a promising candidate for novel cosmetic agents.
