To investigate the antimicrobial activity on bacteria causing a respiration disease and antioxidant effects of water extracts from 12 kinds of wild edible vegetables, we extracted the water extracts for 72 h in $7^{\circ}C$ using distilled water as solvent. The water extracts except Ixeris dentate and Allium monanthum had high concentrations of phenol compounds and flavonoids. Liguraia fischeri specially had the highest level on total phenol compounds and flavonoids with 205 ${\mu}g/mL$ and 98. 86 ${\mu}g/mL$, respectively. The each 0.05% extracts of Sedum sarmentosum and Liguraia fischeri had high effect on the DPPH radical scavenging activity among wild edible vegetables and the most extracts promoted antioxidant activity with increasing concentration of extract. The catalase activity of Erysimum aurantiacum and Aralia elata showed more than 150 units per g of fresh tissue. The effect of antimicrobial activity on water extracts showed characteristic activity. Only Staphylococcus aureus KCTC 1928 and Corynebacterium diptheriae KCTC 3075 were inhibited cell growth on the other hands, the remainder of bacteria was not inhibited cell growth. Nevertheless, the extracts of wild edible vegetables had specific concentration as MIC for antimicrobial activity respectively. In case of the extract of Aster scaber, Erysimum aurantiacum, and Allium monanthum had over 30% antimicrobial activity on the bacteria causing a respiration disease. In results, the wild edible vegetables include high concentrations of total phenol compounds and flavonoids that give a good antioxidant activity and antimicrobial activity. Therefore the wild edible vegetables are functional food for anti-aging and physiological activation.

This study was performed to investigate the effects of Korean native plant diets on lipid and cadmium (Cd) metabolisms and also antioxidative enzyme activities in rats. Seventy male Sprague-Dawley rats weighing 210.3$\pm$2.7g were blocked into ten groups according to body weight. Rats were raised for four weeks with diets containing 0 or 0.04%(w/w) cadmium chloride and 5%(w/w) plant powder-Ssook(Artemisia princeps var. orientalis HARA), Chamchwi(Aster scaber THUNB), Gomchwi(Lingularia fischeri TUBCZ). or Solbeerum (Portulaca oleracea LINNE). Food intake, weight gain, food efficiency ratio, and weights of liver, kidney, spleen and epididymal fat were significantly lower in Cd-exposed groups, food efficiency ratio, and weights of liver, kidney, spleen and epididymal fat were significanlty lower in Cd-exposed groups. Plasma total lipid level, liver total lipid, cholesterol and triglycerde concentrations, and fecal total lipid, cholesterol and triglyceride excretions were decreased by Cd administration. Total lipid and triglyceride concentration in plasma and liver were lower in Chamchwi groups together with increased fecal total lipid and triglyceride excretions. Cholesterol concentration in plasma and liver were lower in Gomchwi groups with increased fecal cholesterol excretions. Activities of red-blood-cell superoxide dismutase(SOD), and liver catalase, SOD and glutathione peroxidase (GSH-px) were decreased significantly by Cd administration. Thiobarbituric acid reactive substance(TBARS) concentrations of plasma and liver were increased by Cd administration. Thiobarbituric acid reactive substance(TBARS) concentration of plasma and liver were increased by Cd administration. Administration of plant diets decreased plasma and liver catalase, SOD and GSH-px activities in Cd-free diet groups and increased them in Cd-administered groups. Plasma and liver TBARS concentrations were decreased in animals fed plant diets, with Chamchwi showing the most effective antioxidative capacity. The concentration of Cd accumulated in blood and tissue decreased in Cd-exposed groups fed plant diets. Liver Cd concentration were lower in the Chamchwi and Gomchwi groups, and kidney Cd levels were lower in the Ssook and Chamchwi groups. Among them, Chamchwi was the most effective in Cd detoxification. In conclusion, Chamchwi and Gomchwi were effective in lowering tissue lipid levels, with Chamchwi having the greatest antioxidative and detoxifying effects.

The study was conducted to investigate candidate materials as anti-inflammation agent from plant resources. Activities of 33 plant parts extracts with the final concentration of 5${\mu}g/ml$ were evaluated on the several inflammation-related markers such as the release of proinflammatoty cytokine [tumor necrosis factor-alpha (TNF-${\alpha}$) & interleukin-6 (IL-6)], nitric oxide (NO), the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and inhibitor of nuclear factor kappa-B alpha ($I{\kappa}-B{\alpha}$) in lipopolysaccharide (LPS)-treated RAW 264.7 cells. The extracts in the final concentration of 10 ${\mu}g/ml$ were also screened on peroxynitrite (ONOO$^-$) scavenging activity. Eleven extracts selected from the screening assay were verified on the inhibition activity on peroxynitrite and total reactive species oxygen (ROS) in the several concentrations. As results, Alpinia officinarum Hance (rhizome), Inula britannica var. chinensis Regel (flower), Ulmus arvifolia Jacq (trunk peel) and Aster scaber Thunb. (aerial part) showed comparatively potent anti-inflammatory activities in vitro cells or chemical level systems, and then these four plant parts should be studied on the antiinflammatory mechanism by further studies.
