In this study, activity of anti-oxidation of Cinnamomum loureiroi extract (CLE). In order to measure anti-oxidation effect of CLE, phenol content of CLE, radical scavenging activity of ABTS and DPPH, and decrease of ROS production. Before the experiment, against Raw 264.7 cell, a cytotoxicity was measured and the result showed no toxicity. CLE's total polyphenol amount was 397.7±8.3 mg/g and the total flavonoid amount was 101.899±0.885 mg/g. As a measurement result of ABTS radical scavenging ability and DPPH radical scavenging ability, radical scavenging ability increased depends on the concentration. CLE's effect on the ROS creation was checked and the result showed that CLE suppressed ROS creation by showing a meaningful decrease of ROS generation. From all of the results, CLE is know to have an antioxidant effect. These results will be provided as fundamental data for further development of the new material of functional cosmetics to the results above.
