  • This study was conducted to investigate the biological activities of Areca catechu L. The antioxidative, fibrinolytic, thrombin inhibitory, and ${\alpha}$-glucosidase inhibitory activities of Areca catechu L extracted with hexane, $CHCl_3$, ethyl acetate, butanol, and water were measured. The water fraction showed the highest extraction yield at 3.65% (w/w). The butanol, $CHCl_3$, water, and ethyl acetate fractions showed strong antioxidative activities at 81.6%, 87.1%, 88.0%, and 89.5%, respectively. The fibrinolytic activity was strong only in the ethyl acetate fraction at 0.84 plasmin units/ml. The 100-fold dilution of the water fraction had the strongest thrombin inhibitory activity at 59.2%. The 100-fold dilution of butanol fraction displayed the strongest ${\alpha}$-glucosidase inhibitory activity at 88.6%. In conclusion, the extracts of Areca catechu L hold promise for use in the development of biofunctional foods to prevent cardiovascular diseases.

  • The present study was performed to compare the antioxidative and whitening activities of fermented soybean extract (FSB) and non-fermented soybean extract (SB). Antioxidative and whitening activities of FSB and SB were evaluated by the determination of DPPH, superoxide radical and hydroxyl radical scavenging activities, linoleic acid inhibition activity, and tyrosinase inhibition activity. FSB showed the higher effect than SB in the antioxidative activities. Also FSB showed the better effect than SB in whitening activity. These results demonstrated that the fermentation played a more excellent role than the non-fermentation in antioxidation and whitening. Therefore, this study suggested that FSB could be a useful cosmetic ingredient for antioxidation and skin whitening.

  • Free radicals formed during the metabolism of environmental chemicals are known to induce mutagenicity, while different types of antioxidants suppress this event. The purpose of this study was to determine the antioxidative and antimutagenic effects of soybean saponins, and to examine the relationship between these two effects for the elucidation of mechanisms involved in the anticarcinogenicity of soybean saponins. Also, antioxidative and antimutagenic effects of soybean saponins were compared with those of kinown antioxidants. For the measurement of antioxidative capacity, soybean saponins, L-ascorbic acid, $\alpha$-tocophoerol, and BHT at concentrations between 005 and 1.0mg/ml were tested for their ability to donate hydrogens and to reduce the formation of thiobarbituric substances(TBARS). Antimutagenic activity was examined using the Ames salmonella test system at concentrations of 600, 900 or 1200ug/ml. Study results showed soybean saponins and all of the other antioxidants tested possessed dose-dependent antioxidative activities. The ability of hydrogen-donation to DPPH was in the order of L-ascorbic acid>$\alpha$-tocopherol=>BHT>soybean saponins. TBARS formation was also inhibited by these compounds, in the order of BHT>$\alpha$-tocopherol=L-ascorbic acid>soybean saponins. Soybean saponins and other antioxidants also showed antimutagenicity in a dose-dependent manner. Especially, soybean saponins and BHT were excellent antioxidants compounds, inhibiting near 80% of the mutagenic effects at a concentration of 1200ug/ml. The correlation coefficients between antioxidative capacity and antimutagenicity for each compund was statistically significant at p<0.05. These results indicate that soybean saponins possess antioxidative and antimutagenic capacities. Also, antimutagenicity of saponins and other antioxidats is partly due to their antioxidative activities.

  • 부추의 in viuo에서의 항산화 및 극-노화효과를 평가하기 위해 ICR 마우스에 2%, 5% 부추식이를 13개월간 급여하면서 항산화 시스템에 미치는 영향을 조사하였다. 간에서의 지질과 산화 정도를 TBARS 값으로 측정한 결과 연령 증가에 따라 지질과산화는 증가하였으나 각 군들간에 유의적인 차이는 나타나지 않았다. 단백질 카르보닐 함량에 있어서는 대조군에 비해 부추식이군에서 유의적으로 낮은 값을 나타내어 부추식이는 조직 단백질 산화를 강력하게 억 제하였고 부추식이군 사이에서는 유의차가 나타나지 않았다 이로써 조직의 과산화를 측정하는데 TBARS보다 단백질 카르보닐 값이 더 예민한 방법임을 알 수 있었다. 간에서의 항산화 효소계 활성을 측정한 결과 SOD 활성은 대조군에서 5개월까지 증가하다가 이후로는 감소하였으나 부추식이군에서는 7개월까지 증가하는 경향을 나타내었는데 활성이 대조군에 비해 300% 이상 현저하게 높았다. GSH-Px 활성은 대조군의 경우 9개월까지 증가하다 감소하였으나 부추 첨가 식이군에서는 가령에 따라 계속 그 활성이 증가하였고 5% 부추첨가 식이군의 효소 활성이 가장 높아 대조군보다 약 200% 높은 활성을 나타내었다. Catalase 활성은 대조군의 경우 연령에 따라 활성의 변화가 없었고 부추 식이군에서 그 활성이 대조군에 비해 유의적으로 높았다. 간조직 내의 총 글루타치온 함량은 대조군에 비해 부추식 이군에서 유의적으로 높은 값을 나타내어 13개월령에서 대조군보다 118% 정도 증가하였다. 따라서 부추 속에 함유된 항산화 물질들과 함황 화합물들이 ICR 마우스의 가령에 따른 항산화 시스템을 적극적으로 보호함을 확인하였다.

  • Objectives : This study was conducted to evaluate the antioxidative and fibrinolytic activity of the water and ethanol extracts from medicinal plants. Methods : Five kinds of medicinal plants(Carthami Flos, Glycyrrhizae Radix, Schisandrae Fructus, Atractylodes Rhizoma, Shiitake mushiroom) were extracted with distilled water and 70% ethanol, and the extracts were tested for their antioxidative and fibrilytic activities. Results : The highest polyphenol contents of the water and ethanol extracts from medicinal plants were 812.52 mg and 685.44 mg per 100 g of Carthamus tinctorius and Schizandra chinensis, respectively. The electron donating abilities (EDA) of the water extracts from all medicinal plants except Lentinus edodes were about 90% at 1,000 ppm and ethanol extracts were higher than those of water extracts. The highest SOD-like activity and nitrite scavenging abilities (NSA) were both of water and ethanol extracts from Schizandra chinensis. Five kinds of medicinal plants had fibrinolytoc activity and the highest activities were water and ethanol extracts from Glycyrrhiza uralensis. Conclusion : These results suggest that the medicinal plants can be used as natural antioxidant to prevent oxidative damage in normal cells probably because of their antioxidative and fibrinolytic activities.

  • The purpose of this study was to examine the antioxidative activities and tissue cell of mouse liver added caffeine. The body weight of all experimental groups increased during experimental periods, but the body weight of caffeine-containing groups were lower than those of any other experimental groups. Superoxide dismutase and catalase activities tended to decrease significantly with caffeine-containing groups, but increased in control and ginseng-containing groups. Hydroperoxide contents were increase significantly with caffeine-containing groups. Lipid peroxidation levels decreased in ginseng-containing groups, but it increased significantly with caffeine-containing group. Protein contents were a tendency of similar between control and ginseng-containing groups, but it showed a increasing tendency in caffeine-containing groups. Microscopic observation of mouse liver cell were similar tissue in ginseng and caffeine-containing groups, but it showed somewhat more injuring only at the liver cell of anhydrous caffeine group, and became the suspicion in liver diseases. This results show that antioxidative activities are slightly higher in non-caffeine and ginseng-containing drinks than caffeine-cotaining drinks. From this standpoint, we suggest that too much drinking of caffeine-containing drinks for a long time is undesirable.

  • Phaseolus aureus (mung bean), Leguminosae, has been used as an antidote from the ancient time. Especially, it has been widely used for cleaning face and skin in oriental countries. Although several constituents such as fatty acids, phytoallexin and phaseol derivatives were reported in P. aureus and related species including seedlings, there has been a few report to describe its biological activity. Therefore, in this investigation, the ethanol extract from P. aureus was obtained and its biological activities including the antioxidative and anti-inflammatory activities were studied. The 70% ethanol extract from P. aureus showed dose-dependent antioxidative activity (52.3% inhibition at 4 mg/ml) against lipid peroxidation assay, while the extract did not show the inhibitory activity of superoxide radical formation. The extract also showed the topical anti-inflammatory activity against croton-oil and arachidonic acid induced mouse ear edema test (18-19% inhibition at 7.5 mg/ear) as well as mild inhibitory activity against picryl chloride induced delayed hypersensitivity in mouse. For investigating active principles, vitexin and isovitexin (apigenin C-glycoside) as flavonoids, and adenosine were isolated from the extract using silica gel chromatography. The actual contents of vitexin and isovitexin were found to be 3.7 and 2.4 mg/g extract, respectively. Vitexin and isovitexin showed the antioxidative activity. They showed the topical anti-inflammatory activity, although the activities were not potent compared to the reference compounds. These results suggested that vitexin and isovitexin may be, at least in part, the compounds contributing the antioxidative activity in vitro and the topical anti-inflammatory activity of P. aureus in vivo. All results of present study might be one of the scientific rationale in using mung bean for skin care from the ancient time.
