  • The purpose of this study was to investigate the effects of aerobic exercise(folk dance) with resistance exercise(elastic band) for 12 weeks on blood MDA concentration and SOD GPx activities in the elderly women. The subjects consisted 12 elderly women between 65-75 years exercise were folk dance(HRmax 50-60% levels, 60min, two per a week) and elastic band(yellow band, 60min, two per a week) program for 12 weeks. SOD, GPx activities in the before combined exercise were significantly increased than that in after combined exercise. These results show that aerobic exercise with resistance exercise program in considered to contribute enforced of antioxidant enzyme system by increased SOD and GPx activities in elderly women.

  • This study was conducted to determine antioxidative enzyme activity in serum of rats as affected by soybean cultivar, extract feeding concentration and fat dietary. In all cultivars, activities of antioxidant enzymes in treatment of various fat compositions and cholesterol followed by feeding soy-extracts were higher than in nonfeeding control, however, no significant differences existed in statistically. The activities of SOD and GSHpx in serum of rats when fed with various fat dietary were higher in Geomjeongkong 1 than in Tawonkong and Hwangkeumkong. Enzyme activities of SOD and GSHpx with each fat compositions in treatment soy-extracts was no significant differences statistically. There was significant differences among cultivars and concentrations of soy-extracts in interaction effect. Also, the activities of GSHpx was significant differences among cultivars and concentrations of soy-extracts and fat composition in interaction effect.

  • To investigate the effect of dietary supplementation of Acanthopanax senticosus (AS) and Eucommia ulmoides (EU) on antioxidant defense system in laying hens, a total of three hundreds sixty 20-wk old Hyline brown commercial laying hens were assigned to five dietary groups for 10-wk: (1) control diet, (2) control diet supplemented with AS at 0.5%, (3) control diet supplemented with AS at 1.0%, (4) control diet supplemented with EU at 0.5% and (5) control diet supplemented with EU at 1.0%. Total antioxidant status (TAS) in blood and antioxidant enzymes including superoxide dismutase (SOD), gluthathione -S- transferase (GST) and glutathione peroxidase (GSH-Px), and lipid peroxidation in the small intestine and liver were measured. There were no changes in body weight for 10-wk dietary treatment. TAS in blood significantly (P<0.05) increased in birds fed the diet supplemented with 1% AS and 0.5 and 1.0% EU compared with those fed control diet. Especially, dietary EU showed much higher (P<0.05) TAS compared with AS. In the antioxidant defense enzymes, GST activity of the small intestine was shown to be significantly (P<0.05) increased in birds fed the diets supplemented with 0.5 and 1.0% EU compared with those fed the control diet. In addition, intestinal SOD activity significantly (P<0.05) increased in birds fed the diets supplemented with 0.5% of AS and EU. However, we could not observe any significant dietary treatment effect of those antioxidant parameters in the liver. In conclusion, dietary supplementation of 0.5% AS and EU in a laying hen diet could be applied as a potential antioxidant source to improves bio-activity of antioxidant and economical aspect in laying hens.

Total Polyphenol Content and Antioxidative Activities of Mistletoe(Viscum album) Extracts by Supercritical Carbon Dioxide (초임계 이산화탄소를 이용한 겨우살이(Mistletoe, Viscum album) 추출물의 폴리페놀 함량 및 항산화 활성)

  • This study was performed to investigate antioxidant activities of Mistletoe (MS) extracts by measuring electron donating ability (EDA), super oxide dismutase (SOD)-like activity and total polyphenol content (TPC). The extracts were obtained using supercritical carbon dioxide, hot-water and ethanol extraction. EDAs was the higher in ethanol extract (70.53%) than water (36.73%) or supercritical carbon dioxide extract (15.73% at 400 bar, $30^{\circ}C$) at concentration of 10 mg/mL. However, SOD-like activities and TPCs were the highest in the supercritical carbon dioxide extract. At concentration of 1 mg/mL, supercritical carbon dioxide extract (22.54% at 200 bar, $40^{\circ}C$) was higher SOD activity than water (7.85%) and ethanol extract (6.12%). Regarding TPCs of MS extracts, the content was the highest in supercritical carbon dioxide extract (17.57 wt% catechin equivalent at 200 bar, $50^{\circ}C$) followed by ethanol and water extract. These results suggest that it can be useful to develop functional foods using antioxidative active compounds of MS with high polyphenol contents.

  • The present study evaluated the antioxidant activity, skin wrinkle reduction, and whitening activity of Pinus koraiensiscone scale extracts made with three different solvents (ethanol, supercritical fluid, and a mixture of both). Total polyphenol content was 11.03 mg/g GAE in the supercritical fluid extractand 33.79 mg/g GAE in the 70% ethanol extract. Electron donating ability of 1,000 ㎍/mL extract was 13.60% in the supercritical fluid extract, 91.37% in 70% ethanol extract, and 71.62% in mixed solvent extract. SOD-like activities in 100 ㎍/mL extract using supercritical fluid, 70% ethanol, and mixed solvents were 16.49%, 21.84%, and 10.7%, respectively. The ABTS+ radical scavenging activities of 1,000 ㎍/mL extract were 38.19%, 80.23%, and 78.72%for supercritical fluid extract, 70% ethanol extract, and mixed solvent extract, respectively. Tyrosinase inhibitory activities in 1,000 ㎍/mL extract were 24.54%, 36.55%, and 15.23% for supercritical fluid extract, 70% ethanol extract, and mixed solvent extract, respectively. Elastase inhibitory activities in 1,000 ㎍/mL extract were 15.62%, 22.56%, and 26.64% for supercritical fluid extract, 70% ethanol extract, and mixed solvent extract, respectively. Skin astringent activity (81.23% with 5000 ㎍/mL extract) was only detected in the 70% ethanol extract. Supercritical fluid and mixed solvent extracts showed no such activity. Our analysis of Pinus koraiensiscone scale extracts show that the highest aggregate activity was found in the 70% ethanol extract, followed by mixed solvent and supercritical fluid extracts. Therefore, our results oppose the hypothesis stating supercritical extract has the highest total polyphenol content and antioxidant activity.
