This study was conducted to determine biological activities, such as lipid peroxidation inhibition, cytotoxicity, sun blocker, inhibition of tyrosinase, and antioxidative effect, of ethanol extracts, and of solvent fractionated ethanol extracts obtained from grape seeds and skins. The strongest lipid oxidative inhibition of 66.9% and 67.6% was observed respectively, in the presence of 20 μg/mL of both ethanol extract and water fraction of grape seeds. Overall, the ethanol extracts and their fractions of grape seeds exhibited stronger lipid oxidative inhibition than that of skin extracts. On the other hand, the ethanol extracts of grape skins showed stronger cytotoxicity than that of seeds on MCF-7, Hep3B, and A549 cancer cell lines. However, the water fraction of seed ethanol extracts showed the strongest cytotoxic effect of 76.52% and 67.01% on MCF-7 and Hep3B, respectively among their fractions. Ethanol seed extracts obtained at 30℃ had the strongest absorbance both at UVA region (350 nm) and UVB region (308 nm) and the chloroform fraction showed the strongest absorbance at UVB region and butanol fraction at UVA region among their fractions, respectively. In the meantime, the ethanol extracts obtained at 30℃ and butanol fraction showed the strongest tyrosinase inhibitory effect of 39.4% and 37.6%, respectively. This study shows that ethanol extracts and their fractions of grape seeds and skins could be potential good materials for functional food and cosmetic products.
