The effects of Allium vegetables on blood glucose levels and lipid metabolism in streptozotocin (S12) induced diabetic rats were investigated. Diabetes mellitus was induced by S1'2 injection (45 mg/kg 5.w.) into the tail vein. Sprague-Dawley rats weighing $220\;{\pm}\;10\;g$ were randomly assigned to 7 groups: normal, S1'2-control and five Allium groups (Allium cepa, Allium fistulosum, Allium sativum, Allium tuberosum and Allium victorialisL Normal and S12control groups were fed an AIN-93 diet and five Allium groups were fed a modified diet containing. 10% Allium powder each for 4 weeks. Body weight, diet intake, food efficiency ratio (FER) and organ weights- were monitored. Activities of aspartate aminotransferase (AST) & alanine aminotransferase (ALT) were observed: Plasma lev~ls of glucose, free fatty acid, triglyceride and HDL-cholesterol were analyzed. Levels of glycogen, cholesterol and triglyceride in liver were determined. Levels of malondialdehyde (MDA) in liver, lung, kidney, and pancreas were assayed. The hepatic contents of chromium (Cr) , iron (Fe), zinc (Zn) and manganese (Mu) were measured. The Allium sativum group had weight gain and suppressed a hypertrophy of the kidney significantly. The activity of ALT was significantly lowered in the diabetic groups except Allium sativum group compared to STZ-control group. The Allium sativum and Allium tuberosum groups showed the hypoglycemic effects at 4 weeks. There were no significant differences between the control and all the other diabetic groups in the plasma levels of cholesterol, HDL-cholesterol, triglycerides and free fatty acids. Most of the Allium groups except Allium fistulosum were observed significantly lowered level of MDA in the lung compared to STZ-control group. The diabetic rats fed the Allium cepa and Allium sativum have shown significantly lowered hepatic Zn contents. The results suggested that the intake of the Allium vegetables may be effective in the antihyperglycemia by lowering blood glucose levels.

To investigate the growth response of various crop species to mycorrhizal inoculation, arbuscular mycorrhizal fungi were applied to Glycine max, Vigna angularis, Senna tora, Hordeum vulgare var. hexastichon. Zea mays, Sorghum bicolor, Allium tuberosum, Solanum melongena, and Capsicum annuum. The biomass of the inoculated crops was measured every two weeks for the 12-week growth period. By measuring biomass, we calculated the mycorrhizal responsiveness of the nine crop species. Among the nine crop species, four species showed a significant response to mycorrhizal inoculation. The shoot biomasses of V. angularis, C. annuum, A. tuberosum, and S. tora significantly increased with mycorrhizal inoculation.

This experiment was conducted to investigate the effects of pH on the mineral nutrient uptake and growth of the four Chinese chives species. The Chinese chives species used in the experiment were the cultivated species grown in the farm (cultivated Allium tuberosum) and three wild species of wild Allium tuberosum, A. thunbergii and A. senescens. The pH levels of soil medium were set to be 4.5, 6.5, and 7.5. Fresh weight(FW) of cultivated A. tuberosum was highest at all pH levels. The increase of soil pH increased the FW of the wild A. tuberosum and A. thunbergii, but no difference was noted for the A. tuberosum and A. senescens. Plant height was higher in the order of wild A. tuberosum, A. thunbergii, and cultivated A. tuberosum and A. thunbergii. Notably plant height of the wild A. tuberosum increased significantly by the pH increase. The Zn content of the wild A. tuberosum was shown to be significantly higher than that of the other species and increased with the increase of soil pH. This indicates that there is a close relationship between the plant height and Zn content in Chinese chives plant. Principal component analysis for characterizing closely related A. species using the factors of plant growth and amounts of nutrients uptake showed that the cultivated A. and wild A. tuberosum were in the $4^{th}$ quadrant of the graph which are classified as the same species, while A. senescens and thunbergii was in $1^{st}$ and $3^{rd}$ quadrant indicating different species, respectively.

This study was performed to investigate the quality characteristics of sponge cake made with leek(Allium tuberosum Rottler) powder. In order to evaluate the physical and sensory properties of different cake, the leek powder was added to wheat flour at various ratios(3, 5, 7, 9%, w/w). The specific gravity of bread dough tends to increase with the addition of leek powder. The moisture levels of the sponge cakes made with leek powder were higher than that of the control. Crumb color values, lightness(L) and redness(a) decreased by leek powder addition, while yellowness(b) was significantly increased (p<0.05). In texture analyses, hardness, cohesiveness, springiness and gumminess decreased with the addition of leek powder. In sensory evaluations, the 3% leek powder sponge cake showed higher sensory property scores than others(p<0.05).

This study was performed to determine the antimicrobial activity of waste food fractions, the Solanum tuberosum Peel (SP) and Allium cepa L. Peel (AP) on several microorganisms. The methanol extracts (SPM, APM) of SP and AP were fractionated to five different types, which were hexane, ethylether, ethylacetate, butanol and water Among the various fractions, ethylether and butanol fractions of AP (APMEE, APMB) showed stronger antimicrobial activity against Pseudomonas aeruginosa and Staphylococcus aureus than the other fractions. The ethylether fraction of SP (SPMEE) also showed the higher antimicrobial activity against Escherchia coli than the other 4 fractions . These results suggest that the waste food fractions, SP and AP may be developed into bioactive antimicrobial health products.

The present study was performed to evaluate the anti-oxidant and anti-proliferating activity of the water extract mixture of Cordyceps militaris (CM) and Allium tuberosum (AT). The water extract mixture rate of CM and AT was optimized by means of a sensory evaluation test. The optimized mixture rate were decided at 70% of CM, 30% of AT, and 10% of apple concentrate as an additive. The values of total acidity, pH, sugar contents, and turbidity of the water extract mixture were 0.1%, 4.28, 9.10 °Brix, and 1.48 respectively. The water extract mixture had effective DPPH radical scavenging activity, reducing power effect, and ABTS radical activity. DPPH radical activities of the water extract and the water extract mixture were 43.2% and 51.7% respectively; their reducing power (OD₇₀₀) was 1.14 and 1.43 respectively; and ABTS^.+ radical activities were 47.1% and 62.2% respectively. Also, the water extract mixture showed a higher anti-proliferating effect than the AT extract on human prostate cancer cells. These results provided experimental evidence that the water extract mixture of CM and AT is a better source of anti-oxidant and anti-cancer ingredients than a single extract of CM. In conclusion, the water extract mixture of CM and AT will be beneficial in development of a functional drink.

This study was carried out to elucidate the effect of mulching materials on the growth of Chinese chive (Allium tuberusum Rottler) and weed control. Chinese chive was grown under five mulching materials, pine leaf, oak leaf, rice straw, rice hull and sawdust, at the Experimental Farm of Chungbuk National University from June 20, 2009 to September 30, 2009. Amaranthus mangostunus, Digitaria sanguinalis, Portuclaca. oleracea, Echinochioa crus-galli var. frumetacea and Setaria viridis were dominant weeds. Both pine and oak leaves were significantly effective mulching materials in terms of weed control indices in both nursery and field. Soil moisture contents were 1.2~3.7% higher in mulching, especially in oak leaf mulching. Mulching with pine leaf significantly increased plant height, sheath length, leaf length, bulb-, root- and leaf-weights and yield of Chinese chive, but there were no significant differences among the other mulching materials although better than those in non-mulching.

The anticarcinogenic effects of various food components have received much attention in recent years. However mechanism of anticarcinogens in food materials on cancer cells have rarely been investigated. This study was performed to investigate the effects on the cytotoxicity and quinone reductase (QR) activity of Allium tuberusum (AT) on the human cancer cells. The six partition layers which are methanol (ATM), hexane (ATMH), ethylether (ATMEE), ethylacetate (ATMEA), butaonl (ATMB) and aqueous (ATMA) of Allium tuberusum were screened for their cytotoxic effects on HepG2, MCF-7, HeLa and SK-N-MC cells by the MTT assay. Among the six partition layers, ATMEE had the strongest cytotoxic effect at concentration of $150\;{\mu}g/mL$ which resulted over 95% on HepG2, HeLa, MCF-7 and SK-N-MC cell lines. The ATMEA also showed significant cytotoxic effect on HepG2 and SK-N-MC cell lines. The ATMB showed the highest induction activity of QR on HepG2 cells among the other partition layers. QR activity of HepG2 cells, grown in the presence of ATMB at the concentration of $50\;{\mu}g/mL$, was increased by 3.9 times, compared to the control value of 1.0. Based on these results, the ATMEE and ATMB may have potentially anticarcinogenic and chemopreventive activities.
