Elaeagnus multiflora, generally referred to as the cherry silverberry, is a plant. Elaeagnus multiflora fruit, leaves, and roots have been traditionally utilized in China as a treatment for cough, diarrhea, itch, and foul sores, and even cancer. More importantly, it is being investigated as a food that is capable of reducing the incidence of cancer, and also as a means of halting or reversing the growth of cancers. Considering the dearth of information regarding the medicinal properties of Elaeagnus multiflora, we assessed the antioxidative and cytotoxic effects of Elaeagnus multiflora by examining its scavenging effects on the 1,1-diphenyl-2-picryl-hydrazyl(DPPH) radical, its inhibitory effects on lipid peroxidation, and its inhibitory effects on cancer cell proliferation in HeLa cells, MCF-7 cells, and SNU-638 cells via MTT assay. Ethanol extracts of Elaeagnus multiflora flesh and seed inhibited DPPH radical production($36.91{\pm}1.00$, $94.17{\pm}0.37$) and lipid peroxidation ($28.18{\pm}5.02$, $40.30{\pm}1.45$, respectively). The Elaeagnus multiflora seed is believed to exert a possible antioxidative effects against the DPPH radical. The ethanol extracts of Elaeagnus multiflora flesh and seed exerted the cytotoxic effects on Hela cells ($6.93{\pm}1.92$, $84.97{\pm}0.47$), MCF-7 cells($5.45{\pm}0.41$, $84.97{\pm}0.47$), and SNU-638 cells($19.39{\pm}0.43$, $76.84{\pm}0.63$) used in this study. This result suggests that Elaeagnus multiflora seeds in contrast to its flesh, is believed to exert a possible anticancer effect. Elaeagnus multiflora seeds are considered to be a the candidate for preventative and dietetic treatment as an anticancer functional food.

본 연구에서는 시판하는 naringin, rutin 및 morin 등의 이소플라본을 시료로 하여 환원력, 전자공여능, SOD 유사활성 및 hydroxyl radical 소거능 등의 항산화특성을 확인할 수 있는 실험을 행하였으며 이들에 대한 마늘 추출물의 영향을 함께 조사하였다. 항산화능을 측정한 모든 실험항목에서 대조군으로서 사용한 합성항산화제인 BHA보다 훨씬 양호한 결과를 나타내었으며, 이소플라본의 농도가 증가함에 따라서도 다소간 증가하는 것으로 나타났지만 그 차이는 크지 않았다. 특히 마늘을 첨가하였을 때는 그 효능이 더욱 상승하는 것으로 나타났는데 마늘의 첨가량을 늘릴수록 그 효능은 더욱 크게 나타났다. 또한 이소플라본 간의 비교에서는 실험항목 별로 특별한 경향은 찾아볼 수 없었는데 환원력에서는 naringin이, hydroxyl radical 소거효과 및 SOD 유사활성에서는 rutin이, 그리고 전자공여능에서는 morin이 다소 우수한 결과를 나타내었다. 따라서 이소플라본의 항산화적 특성이 매우 뛰어남을 확인할 수 있었으며 이러한 작용은 합성항산화제인 BHA보다 우수하여 기능성 식품가공을 위한 주요 소재로서도 유효하게 이용될 수 있다고 생각된다. 또한 마늘의 섭취가 이소플라본의 항산화적 특성에 상승효과를 제공할 수 있는 것으로 나타나 식생활의 올바른 개선에 중요한 역할을 할 수 있을 것으로 여겨지는 바이다.

In vitro cytotoxicity and antioxidative effects of water extracts prepared from Mustard Leaf Kimchi (MLK) during its fermentation period were investigated. The cytotoxicity against HepG2 (human hepatic cancer) by water extracts from the well fermented Mustard Leaf Kimchi was higher than others (fermented for 0 to 6 days at 18$^{\circ}C$), and IC50 of water extracts at the points of 6, 8, 10, and 14days during fermentation were 213.4, 99.2, 99.9, and 109.8${\mu}{\textrm}{m}$/ml, respectively. Antioxidative activity of water extracts from MLK during various fermentation periods was higher than that of blank distilled water. However, the antioxidative activity of well-fermented water extracts of MLK (fermented for 8-14 days) did not show any difference from that of others (fermented for 2-6 days). Thus, water extracts of well-fermented MLK (fermented during 8-14 days) significantly inhibited the growth of cancer cells in vitro, but little antioxidative activity was influenced by the various fermentation periods.

Aerobic cells are normally protected from the damage of free radicals by antioxidative on , zymes such as superoxide dismutase (SOD), catalase, glutathione (GSH) peroxidase, GSH S- transferase and GSH reductase which scavenge free radicals as well as nonenzymatic antioxidants such as ceruloplasmin, albumin and nonprotein-SH including GSH. The effects of each component (ginsenoside $Rb_1$, $Rb_2$, Rc, Rd, Re, $Rb_1$, Rf, $Rh_1$ and $Rh_2$) of red ginseng on the antioxidative enzyme activities were investigated in the liver in order to screen antioxidative components of red ginseng. Ginsenoside $Rb_1$ and Rc showed a tendency to increase GSH peroxidase activity, while ginsenoside Rc significantly decreased Cu,Zn-SOD activity. Especially, ginsenoside $Rh_2$ significantly increased catalase activity. These results suggest that ginsenoside $Rh_2$ is an important active component among total saponins of red ginseng.

The aim of the presents study is to investigate and compare the antioxidative effects and qualities of the cultivating root of Cynanchum Wilfori, which is increasingly used in recent days, with those of the wilding root, which has mainly been used in the past in oriental medicine for a tonic and also for prevention and treatment of various geriatric diseases including aging progress. For comparison of their antioxidative effects, the activities of the total extracts on lipid peroxidation and the activity of aldehyde oxidase(EC 1.2.3.1) as well as xanthine oxidase(EC 1.2.3.2) were investigated in vitro. In addition, their inhibitory effects on the activity of 5-lipoxygenase, which is known to induce inflammation and concerned with free radicals, were also determined in vitro. Furthermore, the amino acid contents of both roots were analyzed in order to compare their qualities. The results are as follows: 1. The wilding root inhibited significantly the activity of 5-lipoxygenase, showing five times more portent than the cultivating root. 2. Both of the wilding root and the cultivating root inhibited aldehyde oxidase activity in a dose-dependant manner. The wilding root was more effective than the other. 3. Both of the wilding root and the cultivating root dose-dependently suppressed lipid peroxidation in rat brain, kidney, and liver. 4. The anti-peroxidative effects of both roots appeared to be most strong in brain and least in liver. In particular, the cultivating root exhibited a significant inhibition on brain lipid peroxidation. 5. The cultivating root contained 15 amino acids including five essential amino acids in contrast with the less contents in the wilding root.

A novel antioxidative peptide (APVPH I, antioxidative peptides from venison protein hydrolysates I) was purified from venison by enzymatic hydrolysis, column chromatography of DEAE-Sephacel, and high-performance liquid chromatography. The molecular mass of the purified peptide was found to be 9,853 Da and the amino acid sequences of the purified peptide was Met-Gln-Ile-Phe-Val-Lys-Thr-Leu-Thr-Gly. The purpose of this study was to evaluate the effects of APVPH I against $H_2O_2$-induced neuronal cells damage in PC-12 cells. Antioxidative enzyme levels in cultured neuronal cells were increased in the presence of the peptide. In addition, APVPH I inhibited productions of nitric oxide (NO), reactive oxygen species (ROS), malondialdehyde (MDA), and cell death against $H_2O_2$-induced neuronal cell damage in PC-12 cells. It was presumed to be APVPH I involved in regulating the apoptosis-related gene expression in the cell environment. The present results indicate that APVPH I substantially contributes to antioxidative properties in neuronal cells.

Mustard Leaf Kimchi (MLK) is a traditional fermented Korean vegetable food. This study was conducted to investigate the effects of part vacuum treatment on MLK packed in a glass bottle during fermentation. There have been a few previous studies that examined the chemical and microbial changes during MLK fermentation. However, the major object of this study was to investigate the antioxidative activities of vacuum treated MLK. In this study, the antioxidative activity of vacuum treated mustard leaf Kimchi (VM) and control mustard leaf Kimchi (CM) were examined. VM and CM were fermented at $5^{\circ}C$ for 8 weeks. A model system was designed to evaluate the antioxidative activity of crude chlorophylls and carotenoids (CCC) extracts from Mustard leaf Kimchi. The oxidative reaction of the linoleic acid mixture system at $30^{\circ}C$ in the dark was quantified determining the peroxide value and conjugated dienoic acid content. The effect of the CCC extracts on lipid peroxidation in a rat liver homogenate was examined. Formation of lipid peroxides was estimated by the TBA value, and the CCC extracts were found to inhibit the TBA value. Chlorophyll a and b, and carotenoids, Which are the major components in the CCC extracts of Kimchi were isolated on a DEAE-sepharose CL-6B and Sepharose CL-6B column and TLC. The effects of chlorophyll a and b, caroteins on linoleic acid autoxidation were measured by determining the peroxide value. In addition, their effects on free radical scavenging were investigated by DPPH. In this assay, chlorophyll a showed the greatest antioxidative activity followed by chlorophyll b, and carotenoids. MLK contains a sufficient content of chlorophyll a and b, and carotenoid which have strong antioxidative activities.
