Studies have been conducted on fermentation products known to increase biological activity through bioconversion of mycelium. In this study, ethanol extract of waxy sorghum (WS) and ethanol extract of waxy sorghum fermented with Phellinus linteus mycelium (WSPM) were prepared, and functional component contents, antioxidant activity, and cytotoxicity were analyzed. Total polyphenol contents and total flavonoid contents of WSPM were higher than those of WS. In addition, the ${\beta}-glucan$ content of WS was higher than that of WSPM. DPPH and ABTS radical scavenging activities showed that WSPM had higher antioxidant activity than WS at all concentrations. Analysis of SOD-like activity also showed higher antioxidant activity in WSPM. MTT assay demonstrated that WSPM exhibited high inhibitory activity in all cancer cells, and in particular, in HeLa cells with the highest inhibition. A concentration-dependent increase in anticancer activities of WS and WSPM was detected in all cancer cells, which was identical to the SRB assay result. MTT and SRB assay showed the increased cytotoxicity of WSPM in cancer cells. Therefore, it is expected that WSPM can be used as a functional food material.

Soybean quality is determined based on protein content, lipid content and fatty acid composition, and several functional components including isoflavones, anthocyanins and functional activity. Because the level of each component changes during seed development, it is necessary to know the concentration of quality-related components in developing seeds. Little is known of the pattern of changes in quality-related components. Seeds from field-grown soybean was harvest from the $R_6$ stage to the $R_8$ stage in 2004. Seed characteristics and the level of nutritional components were examined. Seed moisture content was dropped rapidly after the $R_7$ stage in the tested varieties. Seed growth rate was the highest from the beginning of the $R_6$ stage to the mid-$R_6$ stage. Chlorophyll content was decreased rapidly in pods and seeds. However, seed growth period from the $R_6\;to\;R_8$ was 35 days. The crude protein content was. increased dramatically between 63 DAF and 70 DAF and then increased slightly. The pattern of isoflavone accumulation was nearly similar to that of seed weight increase. From the late $R_6$ stage to the $R_7$, the accumulation rate was higher as compared to other stages. The angiotensin inhibitory activity was increased according to seed development from 63 ($R_6$) to 84 DAF ($R_8$). The difference of inhibitory activity in heated soybean powder, however, was not great among stages. The inhibitory activity was affected by heating treatment. The most effective heating time was 10 min. Excessive heating longer than 30 min resulted in a lowered inhibitory activity of soybean on ACE.

BACKGROUND: Anthocyanins have been recognized as health-enhancing substances due to their antioxidant activity, anti-inflammatory, anticancer, and hypoglycemic effects. The objective was to identify anthocyanins-rich rice grains for the development of functional foods and/or functional food colorants METHODS AND RESULTS: Rice grains of one black and three red-hulled rice varieties were extracted with acidified 80% aqueous methanol. The antioxidant activity of the methanolic extracts was screened on TLC plates and in an in vitro assay using DPPH (1, 1-diphenyl-2-picrylhydrazyl) as a free radical source. Red-hulled rice varieties exhibited higher antioxidant activity (88%, 1 mg/mL) than black rice (67%, 1 mg/mL). Among the red-hulled varieties tested, rice variety SSALBYEO54 (901452) was the most active (72%, 0.5 mg/mL). Rice extracted anthocyanin compounds were analyzed by HPLC-DAD-FLD and LC-MS/MS. Red-hulled varieties comprised cyanidin-3-glucoside in addition to ferulic acid esters, apigenin and kaempferol glycosides. CONCLUSION(s): Anthocyanins identified in the black rice variety were cyanidin-7-O-galactoside, cyanidin-3-Oglucoside, cyanidin-3'-O-glucoside, cyanidin-5-O-glucoside, cyanidin-3, 7-O-diglucoside, cyanidin-3, 5-O-diglucoside and peonidin-4'-O-glucoside. The results of this study show that the black rice (IT212512) and red-hulled rice variety SSALBYEO54 (901452) contain notable antioxidant activity for potential use in nutraceutical or functional food formulations.

The primary objective of this study was to determine the effects of a water-distilled extract with 15 kinds of Korean medicinal herb on antioxidant activity, antimicrobial activity against Helicobacter pylori, and lipid metabolism. The water-distilled extract (WE) and fermenting water-distilled extract (FE) of medicinal herbs were utilized in order to make functional beverages. The EDA (electron donating activity), SOD-like ability, and RAE (relative antioxidant efficacy) of WE averaged 24.47, 50.35, and 1.57%, respectively, but the EDA, SOD-like ability, and RAE of FE was retardeded by 12.01, 35.72, and 1.55%, respectively. The antimicrobial activity against Helicobacter pylori of WE averaged 12.84 mm as a diametric clear zone, and was significantly (p<0.05) higher than those measured in the WE and control. Serum triglyceride contents, total serum cholesterol contents, and serum LDL-cholesterol contents of the WE group were significantly (p<0.05) lower than those of the control group. The liver total-cholesterol contents and liver triglycerides of WE group were significantly (p<0.05) lower than those of the control group. The plasma TBARS value of the WE group was significantly (p<0.05) lower than that of the control group. The sensory evaluation, taste, and smell of FE were more desirable than those of WE, but the color of WE was more desirable. According to the above results, the water distilled extracts (WE) of 15 kinds of medicinal herb are supposed to be effective with regard to antioxidant activity and lipid metabolism, but the antimicrobial activity against Helicobacter pylori was increased as the result of fermentation.

Some biological activities such as an electron donating capacity, the contents of total polyphenol compounds and flavonoids, fibrinolytic activity and $\alpha$-glucosidase inhibitory activity have been detected in hot water extracts of Ligularia fischeri and Angelica gigas Nakai. To increase the usefulness of the functional ingredients for prevention and improvement of some metabolic disorders, ethanol-treated hot water extracts of Angelica gigas Nakai were prepared. A hot water extract of Ligularia fischeri has 92% of electron donating capacity, 39.4 mg/g of total polyphenol compounds, 24.8 mg/g of flavonoids and 29.8% of $\alpha$-glucosidase inhibitory activity, but no fibrinolytic activity. A hot water extract of Angelica gigas Nakai has 94.7% of electron donating capacity, 5.8 mg/g of total polyphenol compounds, 2.6 mg/g of flavonoids, 0.48 plasmin units of fibrinolytic activity and no $\alpha$-glucosidase inhibitory activity. However, with partial purification using cold ethanol treatment, the $\alpha$-glucosidase inhibitory activity of Angelica gigas Nakai was increased to 70.5%. Thus, we expected a more useful effect with the use of the addition of a cold ethanol-treated Angelica gigas Nakai extract. The L, b values of cold buckwheat noodles using a mixture of 0$\sim$3% of Ligularia fischeri powder and 0.5% of an ethanol-treated hot water extract of Angelica gigas Nakai were decreased with the addition of an increasing amount of Ligularia fischeri powder. Among the mechanical qualities, only adhesiveness was significantly higher in 3% Ligularia fischeri noodles. From sensory evaluation data, it was determined that these two functional ingredients did not ruin the color, texture, and overall acceptance of the cold buckwheat noodles. A higher amount of the extracts improved the quality of the product with little added cost.

This study aims to confirm the possibility of using the invasive alien plants in Jeju as a functional biomaterial. To achieve this purpose, 70% ethanol extract and solvent fractions were prepared for five invasive alien plants (Hypochaeris radicata, Rumex acetosella, Humulus japonicus Siebold & Zucc., Solanum viarum, Lactuca scariolar) and their antioxidant, antibacterial anti-inflammatory and anti-obesity effects were investigated. The DPPH radical scavenging activity of ethanol extract from invasive alien plants was shown in the order of Rumex acetosella > Hypochaeris radicata > Humulus japonicus. Antimicrobial activity of ethanol extract against food poisoning bacteria (4 species) and oral cavity-induced microorganisms (6 species) was measured. As a result, the extract of Humulus japonicus showed high antibacterial effects against food poisoning bacteria (E. coli, V. parahaemolyticus) and oral microbes (L. casei, S. epidermidis, E. faecalis). In LPS-induced RAW 264.7 cells, the anti-inflammatory effect of ethanol extract from invasive alien plants was investigated. As a result, the NO production inhibition activity was highest in the Rumex acetosella and the Humulus japonicus Siebold & Zucc. ethanol extract, and the NO production inhibition activity was concentration-dependent. In addition, the Rumex acetosella and the Humulus japonicus Siebold & Zucc. ethanol extract showed a concentration-dependent inhibitory effect on cytokine (IL-6) production. These extracts also showed inhibitory activity of COX-2, an inflammatory protein. This suggests that NO production inhibition activity by the extract of invasive alien plants is the result of inhibition of iNOS and COX-2 expression. Currently, organic solvent fractions of crude extract are manufactured and the investigation of active ingredients is continuing along with evaluation of biological activity such as anti-inflammatory. These results are expected to be a major data for the study on the separation and utilization of active ingredients with antioxidant, antibacterial and anti-inflammatory effects using foreign plant crude extract and solvent fractions, and are highly likely to be applied to the development of functional food and cosmetics materials.

Purpose: This study attempts to understand the effect of stabilization exercise of biofeedback scapular on muscle activity and functional evaluation of the upper extremity in stroke patients. Methods: Patients were divided into two groups; a biofeedback scapular stabilization exercise group comprised of 8 patients and a task-oriented training group including another 8 patients, and 30-minute exercise was performed 5 times a week for 8 weeks. Electromyogram was used to measure muscular activity of lower trapezius, deltoid middle, and serratus anterior. Fugl-Meyer Assessment and Manual Function Test were used to evaluate functions of the muscles mentioned. Results: Significant difference was observed in the comparison group before and after exercise in muscular activity of lower trapezius, deltoid middle, and serratus anterior, Fugl-Meyer Assessment, and Manual Function Test. Conclusion: Therefore, we could see that biofeedback scapular stabilization exercise is more effective than task-oriented training in facilitating muscle activation and functional capacity of upper limb.
