This study aimed to investigate the blood glucose regulatory effect of barley noodles contained mulberry leaves water extract (MLWE) in diabetic mice in order to provide fundamental data as a functional food. ICR mice were divided into six groups as follows: normal control, positive control, barley control, mulberry control, barley+MLWE 2.5% and barley+MLWE 5% groups. High fat/high carbohydrate diet was fed for 4 weeks and diabetes mellitus was induced by i.p. injection of streptozotocin and nicotinamide. After diabetes induction, experimental diet was supplemented for 2 weeks and simultaneous measurement of body weight, blood glucose (including glucose tolerance test), liver function and blood lipid profile was conducted. As a result, there was less decrease in body weight compared to the positive control group in the groups that supplemented barley and MLWE together than the group ingesting barley and MLWE alone. In addition, regulatory effects on blood glucose, liver function and blood lipid concentration were also stronger in barley and MLWE concurrently supplemented groups. Consequently, combination of barley and MLWE was effective in the regulation of body weight, blood glucose, liver function, and blood lipid in diabetic mice. Therefore, this recipe could be a promising strategy for beneficial effects in the patients of diabetes mellitus.

Post-harvest treatment for barley production requires many steps including drying, cleaning, and packing, and these steps be needed many labor input. Rice processing complex (RPC) is useful for post harvest management system in rice production. However, it is rare to be used for barley production. This study was conducted to explore the variations of quality and labor saving between conventional method and bulk-management system in post-harvest using RPC. The sorting rate was not different between manual method and bulk management. The hardness of non-polished grain was ranged 10,175-10,329 g/$3.14mm^2$, and that for non-polished grain was higher than that for polished grain, but there was not different between drying method. There was not be showed the hunter's value such as L, a and b according to drying method. Cooking characters such as water absorption ratio, swelling ratio, and water soluble extracts by circulated or continued dryer was higher than manual drying using solar heat. Labor input per ha for each cultivation process in bulk-management of barley using rice processing complex was 21 hours, compared to 46 hr/ha in the conventional method, labor input was greatly saved by up to 54.3% in the post-harvest bulk management system.

Papilla and cytoplasmic aggregates clearly formed on the epidermal cells of barley leaves in response to the primary germ-tubes of Erysiphe graminis f. sp. hordei, but their sizes were much smaller than those in response to the appressoria. Some cells of barley leaves exposed to powdery mildew for 36-48h were more deeply stained as compared to the other cells by acid fuchsin. However, the content of malondialdehydein in powdery mildewed leaves, one of the product of lipid peroxidation, did not increase by 96h after inoculation. Positive reactions for callose, protein and phenolics were recognized in the papilla and cytoplasmic aggregates at 6h after inoculation, but cutin, suberin, cellulose and lignin were not noticeable until 72h after inoculation. The total phenol content in methanol extracts increased with increasing time after inoculation. All histochemical reactions were not race-specific in barley­powdery mildew combinations tested.

In this study, the antibacterial activities of selected barleys (UB, unhulled barley; PB, pearl barley; and NB, naked barley) and wheat (WG, wheat with germ and endosperm) extracts were evaluated against the food-borne pathogens Staphylococcus aureus KCTC 1927, Escherichia coli KCTC 2593, Salmonella Typhimurium KCTC 2054, and Bacillus cereus KCTC 1014. The amount of the antibacterial biomarker, 2,6-dimethoxy-1,4-benzoquinone (DMBQ), present in selected barleys and wheat, was measured by HPLC. Furthermore, antioxidant activity of samples was determined using the oxygen radical absorbance capacity (ORAC) assay. WG ($22.35{\pm}0.04mm$) was found to be highly inhibitory to Staphylococcus aureus followed by UB ($17.91{\pm}0.10mm$), PB ($16.87{\pm}0.05mm$), and NB ($15.69{\pm}0.20mm$). The antibacterial activity of the selected grains was correlated with antioxidant activities and the amount of DMBQ (Pearson's correlation coefficient, 0.7831). The antioxidant activity of the selected grains was also correlated with the total phenolic content (Pearson's correlation coefficient, 0.9934). WG extract showed significantly higher antibacterial activity, compared with barley extracts such as UB, PB, and NB. The results of this study suggest that barley has a potential in the development of natural antimicrobials and food preservatives for controlling food-borne pathogens.

In order to develop of health-oriented convenience foods for rice consumption, functional Misutkaru drink was made by adding several medicinal herbs extracts to fundamental Misutkaru based cereal powder(rice, barley and soybean). Fundamental Misutkaru drink was prepared with the ratio of cereal mixed rice(5g), barley(5g) and soybean(5g) on water (100 mL) and several medicinal herbs extracts. Liriopis Tuber(50%), Omija(15%), Ginseng(10%) and Jujube(25%) were mixed to fundamental Misutkaru as functional Misutkaru. And then it was extracted to added water of 10times during 36hrs at 75$^{\circ}C$. For instant Misutkaru drink of health-oriented convenience foods, mixture of them was made with fundamental Misutkaru drink(80%), extract of several medicinal herbs(20%), and it's sensory score was high. Autoclaved functional Misutkaru drink for long storage period was changed rheological type badly. Overall acceptability and storage period of nonautoclaved functional Misutkaru drink to added extract of several medicinal herbs was higher than fundamental Misutkaru drink.

Lettuce (Lactuca sativa L.) is known to contain water-soluble substances that are biologically active. Aqueous or methanol extracts and residues from leaves of lettuce plants were assayed to determine their allelopathic effects, and the causative allelochemicals from fractions were quantified by means of HPLC analysis and bioassayed. Extracts from oven-dried leaf samples were more phytotoxic than those from freeze-dried samples. Leaf extracts of 40 g L$^{-1}$ were completely inhibitory on root growth of alfalfa (Medicago sativa L.), while root growths of barley (Hordeum vulgare L.) and soybean (Glycine max L.) were less sensitive. Early seedling growth of both alfalfa and barnyard grass (Echinochloa crus-galli) was significantly reduced by methanol leaf extracts. The major allelopathic substances analyzed by HPLC were coumarin, trans-cinnamic acid, o-coumaric acid, p-coumaric acid and chlorogenic acid. Of them p-coumaric acid was found as the greatest amount (8.9 mg 100 g$^{-1}$ ) in the EtOAc fraction; only coumarin was found in all the fractions. Hexane and EtOAc fractions of L. sativa reduced alfalfa root growth more than did BuOH and water fractions. These results suggest that lettuce had potent herbicidal activity, and that its activity differed depending on type and amount of causative compounds by fraction.

In order to evaluate the physicochemical properties of sludge compost and to identify the effects water-extracts from sludge compost in 2, 6, 8, 12 weeks of decomposing process on seed germination and root elongation in cabbage, lettuce, soybean and barley plants was investigated. The content of total nitrogen in sludge compost increased slightly in 6 weeks decomposing process, and then decreased gradually. Organic matter content decreased continuously overall decomposing process. As decomposition was processing, pH of sludge compost decreased slightly, and EC increase within 6 weeks decomposing process, and then decreased. The content of nitrogen in water-extracts from sludge compost increased within 8 weeks decomposing process and decreased in 12 weeks decomposing process. The content of ammonium nitrogen was similar with that of total nitrogen, and the ratio of ammonium and nitrate increased within 8 weeks, and then decreased. Cation content and EC decreased the late of decomposing process and pH didn't change. The water-extracts from sludge compost during decomposing process inhibited seed germination and root elongation in cabbage (Brassica campestris), lettuce (Lactuca sativa), barley (Hordeum vulgare) and soybean (Glycine max). The inhibition of root elongation in cabbage was greater than that of relative seed germination, whereas relative seed germination in lettuce was more inhibit than root elongation. Relative seed germination and root elongation in soybean were inhibited slightly, but those of in barley was inhibited strongly. In this study, we would identify the effects of water-extracts from sludge compost on seed germination and root elongation was different to the species of seed. The inhibition of seed germination and root elongation treated with the water-extracts which extracted from sludge compost in the early stage of decomposing process was greater than that of in the late stage of decomposing process.

This research has been carried out to find out the highest effect on insecticidal, fungicidal and herbicidal activities in leaves, stem and tuber extracts of yacon (Smallanthus sonchifolius) and extraction methods such as water, boiling water and methanol. Characteristics of potential herbicidal components among extraction methods were investigated by solvent fractions such as hexane, chloroform, ethyl acetate, butanol, and water. Generally, methanol extract was the best on inhibition of germination rate, plant height, and root length in cucumber and barley. On the other hand, the inhibition effect on growth in cucumber and barley was the best in tuber among plant parts of yacon. Inhibition of germination rate, plant height, and root length in cucumber and barley in solvent fractions was the best in water fraction, but there were no differences in other fractions. Digitaria sanguinalis L. and Solanum nigrum L. by 5 and 10% extractions of yacon tuber were controlled by more than 70~80% and 95~100%, respectively. However, there was no inhibition effect on foliar treatment in cucumber and barley as affected by 5 and 10% extractions of yacon tuber. Mortality of green peach aphid (Myzus persicae Sulzer) was 50% at 3 days after treatment of 5% extracts of yacon leaves. Mortality of brown plant hopper (Nilaparvata lugens Stal) was only 24% in 5% extracts of stems and leaves with midrib, but was 57% in 5% extracts of leaves without midrib. There was no fungicidal effect on anthracnose (Colletotrichum truncatum), wilt disease (Fusarium oxysporum), verticillium wilt (Verticillium dahliae), bacterial blight (Xanthomonus oryzae) in 5% extracts of yacon leaves.
