Abstract

The purpose of this study was to evaluate the antioxidant components and activities of HR02/04(8:2)-W, a mixture of S. quelpaertensis Nakai and F. erecta var. sieboldii. We investigated the p-coumaric acid, total flavonoid, and total phenol contents. To evaluate the antioxidant efficacy, we measured the 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2’- azino-bis(3-ethylbenzthiazoline6-sulfonic acid) diammonium salt (ABTS) radical scavenging activity, FRAP activity, reducing power, and ORAC value. We observed the protective effect of hydrogen peroxide against cell damage in human dermal fibroblasts. As a result of the experiment, the p-coumaric acid, total flavonoid, and total phenol contents were 75.62±1.56 mg/100 g, 21.57±0.84 mg rutin equivalent (RE)/g, and 21.25±1.31 mg gallic acid equivalent (GAE)/g, respectively. In the experiments on antioxidant activity, HR02/04(8:2)-W was found to have significantly increased antioxidant activity. In the human dermal fibroblasts, the HR02/04(8:2)-W treated groups could effectively protect cells against oxidative damage. In this study, we confirmed that HR02/04(8:2)-W is a material with effective physiological antioxidant activity.
