Abstract: This study assessed the anti-oxidative and anti-aging efficacies of amaranth extract and measured its applicability as a natural ingredient for multi-functional cosmetics. For this, the leaves and flowers of Korean native amaranth were extracted with 80% ethanol and two samples were obtained. After performing DPPH and ABTS assays, both collagenase and elastase inhibitory activities were measured. The data were then statistically analyzed. The results found the following: In terms of the antioxidant capacity of the two substances, both DPPH and ABTS radical scavenging activities revealed similar results which were dose-dependent. In collagenase and elastase inhibitory activities, the results were better than other natural materials that have recently been studied such as Eleutherococcus senticosus and Paeonia suffruticosa. Therefore, it was confirmed that amaranth extract would be suitable as an anti-aging ingredient that can prevent skin aging from ultraviolet rays or free-radicals. The said results prove the possibility of amaranth extract as a natural ingredient for multi-functional cosmetics. With the recent heightened interest in inner beauty, the development of an ingredient for cosmetics using food would be more meaningful.
