The purpose of this study was to evaluate the antioxidative activities of jeolpyun containing Cnidium officinale M extract (2%, 4%, 6%, 8%) by total polyphenol contents, electron donating ability on 2,2-diphenyl-1-picrylhydrazyl (DPPH), scavenging ability of superoxide anion radical and decomposing ability of hydrogen peroxide. In chromaticity analysis, the brightness significantly decreased with increasing Cnidium officinale M extract content. Jeolpyun containing 8% Cnidium officinale M extract revealing the highest value for the redness and the yellowness, 1.07, 12.70, respectively. The total polyphenol contents of jeolpyun containing 8% Cnidium officinale M extract were the highest content of 4,213 ㎍ gallic acid equivalent (GAE)/mL. The total polyphenol contents revealed significant difference (p<0.05). Jeolpyun containing 8% Cnidium officinale M extract revealing the highest electron donating ability (83.55%). The electron donating abilities were significantly related at p<0.05. The scavenging abilities of superoxide anion radical for jeolpyun containing 4% Cnidium officinale M extract revealed the highest ability (0.01676). There was no significant difference. The hydrogen peroxide decomposing ability for jeolpyun containing 8% Cnidium officinale M extract revealed the most hydrogen peroxide decomposing ability (-0.193) and the hydrogen peroxide decomposing ability revealed a significant difference (p<0.05).

In this study, antioxidative activities of Jeolpyun containing Smilacis chinae R. extract powder (2%, 4%, 6%, 8%) were evaluated using total polyphenol contents, electron donating ability on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and decomposing ability of hydrogen peroxide. In chromaticity analysis, the brightness significantly decreased with increasing Smilacis chinae R. extract powder content. Jeolpyun containing 6% Smilacis chinae R. extract powder revealed the highest value (9.67±0.603) for the redness and 2% Smilacis chinae R. extract powder was the highest value (14.20±0.917) for the yellowness. Total polyphenol contents of Jeolpyun containing 8% Smilacis chinae R. extract powder were the highest content of 17,320±390.38 ㎍ gallic acid equivalent/mL (GAE/mL). Total polyphenol contents were significant relation at p<0.05. Electron donating ability for Jeolpyun containing 8% Smilacis chinae R. extract powder revealed the highest electron donating ability (74.24±0.827%). Electron donating abilities revealed significant difference (p<0.05). Jeolpyun containing 6% Smilacis chinae R. extract powder revealed the most hydrogen peroxide decomposing ability (-3.38±1.44) and hydrogen peroxide decomposing ability revealed significant difference (p<0.05).

In this study, the antioxidative activity of Jeolpyun containing S. glauca (Bunge) Bunge powder (2%, 4%, 6%, and 8%) and extract (2%, 4%, 6%, and 8%) was evaluated based on the total polyphenol contents, electron-donating ability, scavenging of superoxide anion radical, and decomposition of hydrogen peroxide. Total polyphenol contents of Jeolpyun containing 8% S. glauca (Bunge) Bunge powder were the highest with a value of 2,280±0.00 ㎍ GAE/mL. It was observed that total polyphenol content exhibited a significant relation with concentrations at p<0.05. The electron-donating ability of Jeolpyun containing 8% S. glauca (Bunge) Bunge extract was the highest with a value of 83.93±0.69%. The electron-donating abilities revealed significant differences between concentrations (p<0.05). The superoxide radical scavenging ability of the blank was 0.01523±0.00068 and Jeolpyun containing 6% S. glauca (Bunge) Bunge powder was the highest with a value of 0.00977±0.00842. The hydrogen peroxide decomposing ability of Jeolpyun containing 0% S. glauca (Bunge) Bunge powder was -0.00377±0.0049; 8% S. glauca (Bunge) Bunge powder revealed the highest decomposing ability of -0.0476±0.0234. Hydrogen peroxide decomposing abilities revealed significant differences between concentrations (p<0.05). Jeolpyun containing S. glauca (Bunge) Bunge powder and extract demonstrated improved antioxidative activities.
