In order to compare the anti-inflammatory effects of five selected cereal grains-proso millet, hwanggeumchal sorghum, foxtail millet, barnyard millet, and adlay-the inhibitory activities of 80% ethanol (EtOH) extracts obtained from the individual grains on lipopolysaccharide (LPS)-induced nitric oxide (NO) generation were investigated in RAW264.7 cells. The EtOH extract of barnyard millet (Echinochloa crus-galli var. frumentacea) grains exhibited more potent anti-inflammatory activity than that of the other grains. When the EtOH extract of barnyard millet grains was sequentially fractionated with n-hexane, methylene chloride (MC), ethyl acetate (EtOAc), and n-butanol, the majority of the anti-inflammatory activity was detected in the MC fraction, followed by the EtOAc fraction. Pretreatment with the MC fraction caused downregulation of the expression levels of iNOS- and COX-2-specific transcripts and proteins, as well as proinflammatory cytokine gene transcripts (IL-$1{\beta}$, IL-6, and TNF-${\alpha}$) in LPS-stimulated RAW264.7 cells. Additionally, the MC fraction could suppress not only the LPS-induced nuclear translocation of cytosolic NF-kB, but also the LPS-induced activation of MAPKs, such as ERK, JNK, and p38MAPK. Further analysis of the MC fraction by HPLC identified kaempferol, biochanin A, and formononetin as the major phenolic components. Both kaempferol and biochanin A, but not formononetin, could exert anti-inflammatory effect at the same concentrations as those of the MC fraction. Consequently, these results indicate that kaempferol and biochanin A are among the most effective anti-inflammatory phenolic components in barnyard millet grains. This finding suggests that barnyard millet grains and the MC extract enriched in kaempferol and biochanin A could be beneficial functional food sources that have an anti-inflammatory effect.

It has been known that diseases related with aging or cancer result, at least in part, from free radicals, and antioxidants may reduce or prevent the abnormalities associated with free radical formation via its scavenging action. Thus, this study was carried out to investigate the antioxidative and antimicrobial activities of nut species for the purpose of developing antioxidant from natural products. Antioxidant activities of four kinds of nuts such as chestnut, groundnut, walnut and acorn were examined by measuring the radical scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. The extracts from chestnut hull and acorn barnyard millet showed strong antioxidative activities among 10 samples tested. Because of their highest antioxidative activity among 10 samples, radical scavenging effects of 4 different extract compartments (Hexane, EtOAc, BuOH and $H_2O$ extracts) from chestnut hull and acorn barnyard millet, were further examined by DPPH method. EtOAc and BuOH extracts exhibited antioxidative activities similar to those of natural, tocopherol or synthetic antioxidants, BHA. These findings demonstrates that major fraction of the antioxidative activity of chestnut hull or acorn barnyard millet was the EtOAc and BuOH extract compartments. However, antimicrobial activities against food-related bacteria and yeasts was relatively weak.

To examine the antioxidant activities of 11n selected miscellaneous cereal grains (proso millet, yellow glutinous proso millet, hwanggeumchal sorghum, glutinous sorghum, white glutinous sorghum, yellow glutinous foxtail millet, nonglutinous foxtail millet, green glutinous foxtail millet, golden foxtail millet, barnyard millet, and adlay), the free radical-scavenging activities of 80% ethanol extracts of the individual grains were investigated using 1,1-diphenyl-2-picryl-hydrazl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) methods. The ethanol extracts of hwanggeumchal sorghum, glutinous sorghum, and barnyard millet grains exhibited more potent free radical-scavenging activities as compared to the other grains. When these three ethanol extracts were sequentially fractionated with n-hexane, methylene chloride, ethyl acetate, and n-butanol, the majority of the antioxidant activities were detected in the ethyl acetate and butanol fractions in which phenolic ingredients were abundant. The ethyl acetate and butanol fractions of hwanggeumchal sorghum and the ethyl acetate fraction of glutinous sorghum showed higher antioxidant activity than that of ${\alpha}$-tocopherol. Both ferric thiocyanate (FTC) and thiobarbituric acid (TBA) methods demonstrated that these organic solvent fractions could inhibit lipid peroxidation. The ethyl acetate fractions from hwanggeumchal sorghum, glutinous sorghum, and barnyard millet grains could suppress tertiary-butyl hydroperoxide (TBHP)-induced apoptotic events, including sub-G1 peaks, ${\Delta}{\Psi}m$ loss, activation of caspase-9 and caspase-3, and cleavage of PARP and lamin B, in human HL-60 cells. These results show that the grains of hwanggeumchal sorghum (Sorghum bicolor L. Moench cv. Hwanggeumchalsusu), glutinous sorghum (Sorghum bicolor L. Moench cv. Chalsusu), and barnyard millet (Echinochloa esculenta) possess efficient antioxidant activity, which could protect cells from oxidative stress-mediated cytotoxicity.

The edible barnyard millets(Echinochloa spp.) which have essentially vanished in the farmhouses environment and in agricultural germplasm were evaluated with the aim of restoration as a crop. The proximate components and mineral elements of milled millet were nutritionally similar or better than brown rice, and the vitamin contents of $B_1$ and $B_2$ exceeded those of rice by 1.3 times and 2.3 times, respectively. ${\beta}$-Carotene which is absent from brown rice was detected at levels ranging from 15~31 ${\mu}g$ in millet samples. Nine essential amino acids, including histidine and arginine and eight non-essential amino acids, such as aspartic acid were detected. The sum of all amino acids was determined to be IEC518>525>510 in the range of 69~106 mg/g. Analysis of physiological active substances via their electron donating ability(EDA) revealed values ranging from 3.4~8.2%, with the total polyphenol component being 51.1~69.4 mg/g and ${\alpha}$-glucosidase inhibition ability determined as 8.3~10.9%. In terms of agronomical characteristics and yields of barnyard millet, three millet varieties(IEC510, 518, and 525) were suitable as edible crops. IEC525 was selected as optimum variety for cultivation on the basis of nutritional ingredients, physiological active substances, and yield.

Accurate measurements of feed energy values have a positive effect on the control of feed intake for animals, the formation of prices, and on economic profits. However, few studies have attempted to measure the energy values of domestic roughages and to validate an energy value prediction model. The purpose of this study is to build a database through measurements of the nutrient digestibility and digestible energy results of roughages used in Korea and to evaluate the domestic applicability of the National Research Council (NRC) estimation model. Oat hay, annual ryegrass, tall fescue, barnyard millet, and concentrates for beef cattle were used in the test. As a result of an in vivo digestibility trial, the total digestible nutrients (TDN) of oat hay, annual ryegrass, tall fescue, and barnyard millet were found to be 68.73, 55.02, 55.71, and 52.89%, respectively. As a result of comparing the estimated values using the NRC equation with the in vivo results, there was a difference of 3.55 to 6.84%P in the TDN. Inferred from this result, it is considered that TDN calculations using the NRC equation can be reasonable for the test feeds used in this study. These results can be utilized when revising the Korean Standard Tables of Feed Composition, which provides a comprehensive overview of Korean feed.

A phytotoxin was purified by repeated chromatography from liquid cultures of Fusarium oxysporum BG isolated from barnyardgrass. Its chemical structure was determined to be dehydrofusaric acid by mass and NMR spectral analyses. The substance showed a potent phytotoxic activity against growth of duckweed with a $EC_{50}$ value of $1.5{\mu}g/ml$. It also inhibited the root growth of barnyard millet, cress, barnyard grass, and rice cultivar 'Dongjin'. However, it had no inhibitory activity against seed germination of barnyard millet and cress, and the shoot growth of the four plant species.

This study was performed to compare the physiological effects of puffed snack on diabetic and geriatric diseases using miscellaneous cereals and grain crops. The puffed snacks were prepared with different amounts of miscellaneous cereals and grain crops (in ratios of 10%, 20%, and 30% of brown rice). Changes in the water soluble index, water absorption index, color, antioxidant activity, total polyphenol content acidity, ${\alpha}$-glucosidase inhibition activity, and sensory evaluation were also determined. As the cereal and crop contents increased, the value of the water soluble index increased while the water absorption index decreased, with the exception of glutinous foxtail and barnyard millets. With respect to color, lightness and yellowness decreased in concert with increases in the cereal and crop contents, whereas redness increased. Furthermore, the antioxidant activity and total polyphenol content as well as ${\alpha}$-glucosidase inhibition activity increased remarkably with increasing concentrations of sorghum. There was no significant difference in the physiological activities depending on the addition of millet, barley and barnyard millets. In sensory evaluation, the puffed snacks containing sorghum, millet, and glutinous foxtail millet received higher values than other samples. Altogether, our results indicate that puffed snacks containing 10~20% sorghum could be suitable as ingredients for improving sensory and physiological activities in diabetic and geriatric diseases.
