Advanced glycation end products (AGEs) are final products formed by glycation reaction between reducing sugars and proteins, lipids or nucleic acids. These AGEs are related to progress of skin aging. In this study, we evaluate anti-aging activity of Defatted Torreya nucifera seed extract (DTSE) through antioxidant, anti-glycation, anti-elastase and inhibitory and breaking activity on the cross-linking of AGEs to collagen assay. Results showed that DTSE contained polyphenols and flavonoids. The $IC_{50}$ values of 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity were $16.4{\mu}g$ (Dried materials, DM)/mL and $16.7{\mu}g\;DM/mL$, respectively. DTSE also inhibited the formation of AGEs, elastase activity and cross-linking of AGEs to collagen as well as broke existing cross-linking of AGEs to collagen in a dose-dependent manner. Consequently, our findings suggest that DTSE could be useful as a cosmetic material with anti-aging activity.
