This study investigated the potential of Vitis amurensis seed extracts, a species closely related to grapes, as a cosmetic and functional food ingredient. The total phenolic and flavonoid contents were measured, and the antioxidant activity, α-glucosidase inhibitory activity, and tyrosinase inhibitory activity were evaluated. The total phenolic and flavonoid contents of the V. amurensis seeds were found to be 36.1 and 18.7 mg/g, respectively. The IC50 values for the DPPH and ABTS radical scavenging activities of the V. amurensis seed extracts were 24.5 and 16.7 μg/ml, respectively, indicating significant antioxidant effects. Additionally, the whitening and antidiabetic activities were assessed, with the IC50 values for tyrosinase and α-glucosidase inhibition found to be 61.7 and 124.8 μg/ml, respectively. These results suggest that the V. amurensis seed extracts possess antioxidant, whitening, and antidiabetic effects, indicating their potential as functional materials in the future.
