    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 <i>Eleutherococcus senticosus and Paeonia suffruticosa</i>.
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.
