  • The effect of garlic on glutathione S-transferase activity and the level of glutathione in the mouse liver was studied. the intraperitoneal injection of the methanol extract of garlic and ally sulfide which is one of possible active compounds in garlic to ICR mouse before the injection of aflatoxin B1 (AFB1) increased the levels of glutathione and nonprotein-SH in microsomal fraction of the livers. The injection of the chloroform fraction 2 which revealed the highest antimutgenic activity in our previous research in the increase of the activity of glutathione S-transferase and the levels of glutathione and nonprotein -SH. The glutathione itself also had the antimutagenic effect on AFB1 and N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in Salmonella typhimurium TA98 and TA100 in vitro.

  • The antiatherogenic effect of kimchi ingredients was studied in terms of antioxidative effect against Newzealand white rabbits that fed 1% cholesterol. Experimental groups was fed 8% Baechu (Brassica pekiinensis), or 1% red pepper(Capsium annum), or 1% garlic(Allium sativum) for 12 weeks. Blood samples were drawn every 2 weeks to analyze vitamin E, POV, and TBARS. Hepatic antioxidative enzyme activity, vitamin E, and carotene concentration also were measured. Plasma TBARS and POV level were markedly lowered in both red pepper and garlic fed rabbits(p<0.05) compared to control. Hepatic POV and protein carbonyl values were lowered in the rabbits fed kimchi ingredients compared to control(p<0.05). Plasma vitamin E concentration was increased in the rabbits fed red pepper and garlic compared to control(p<0.05). Hepatic vitamin E concentration was increased in red pepper and garlicfed rabbits compared to control. For the hepatic antioxidative enzyme acitivity, catalase activity was significantly increased in red pepper and garlic fed rabbits compared to control. Therefore, Baechu, red pepper, and garlic exert an antioxidative effect against rabbits fed 1% cholesterol for 3 months.

  • This experiment was conducted to elucidate the effects of mulching materials and removing time of the transparent polyethylene (PE) film on the growth of garlic at Uiseong experimental field, Korea. The experimental mulching materials comprised of transparent polyethylene film (0.025 mm) and net polyethylene (NPE). Plant height and leaf number of garlic were highest at PE treatment when the PE removing date was March 18 and this treatment also promoted the no. of cloves. Length of leaf sheath and bolting rate were highest and bulb weight loss rate was lowest at PE + NPE treatment when the PE removing date was March 18. But clove number was the lowest in this treatment compared to conventional PE film treatment. Conventional mulching method accelerated secondary growth rate but bulb weight loss was vice versa. There were statistically no differences in bulb diameter among treatments but conventional treatment positively focused on bulb diameter. Whenever PE film remove can suppress weeds compared to no mulching treatment but the dry weight of weeds were increasing trends as the removal dates of PE film were delayed. Transparent PE or PE + NPE treatments can be recommended to grow best quality garlic when PE film removing date is March 18.

  • Effects of packing materials on the gas compositions in package of fresh peeled garlic (Allium sativum L.) were investigated. The fresh peeled garlics packed in $20,\;40,\;60\;{\mu}m$ LDPE and $30\;{\mu}m$ HDPE pouches were stored at $20^{\circ}C$, 76% RH. The variables including respiration characteristics, gas compositions, general appearance, and film permeabilities to $O_2$, $CO_2$ and $H_2O$ vapor were measured. A model was evaluated for the prediction of $O_2$ and $CO_2$ equilibrium concentrations inside packages and for the optimization of packaging parameters. Experimental and simulated gas composition results were found to be in good agreement. The $30\;{\mu}m$ HDPE pouch with 4% $O_2$ and 7.5%$CO_2$ equilibrium concentrations conferred the best appearance of peeled garlic, giving 6 days of storage life. As a result, MA seemed to have a beneficial effect on appearance of fresh peeled garlic, possibly due to reduced microbial activity.

  • For developing an integrated eco-friendly package against root knot disease complex of mulberry caused by the association of Meloidogyne incognita with Fusarium solani and F. oxysporum causing serious loss in terms of leaf yield and quality during cultivation, twenty botanical extracts at 5, 10 & 20% concentrations were screened under in vitro conditions. Among the extracts, Allium sativum followed by Lasownia inermis were found to be effective at 20% concentration against both the virulent fungi and nematode. Both the extracts reduced the mycelial growth of virulent fungi to an extent of 76-100%, inhibited the hatching of nematode eggs by 80-90% and 76-85% larval mortality over the control. The other extracts were found either moderately or poorly effective in reducing the growth of fungi, hatching of nematode eggs and enhancing the mortality of larvae. The two effective botanical extracts, which rated as strong inhibitors against both nematode and virulent fungi, can be utilized in developing an integrated ecofriendly technology for better management of root knot disease complex in mulberry.

  • 본 연구에서는 마늘 중의 항미생물 작용을 가지고 있는 allyl-2-propenyl-1-thiosulfinate의 유사체들인 alkyl thiosulfinate 및 이의 산화물인 thiosulfonate화합물들을 합성하고 이들의 생물 활성을 검사하였다. Alkylsulfinate는 이황화 화합물(disulfide)를 유기 과산화산으로, 또 alkyl thiosulfonate는 thiosulfinite를 sodium periodate로 산화시켜 합성하였다. 합성한 모든 alkylthiosulfinate 및 alkyl thiosulfonate들은 Staphylococcus aureus B33에 대해서는 항세균성을, Candida utilis ATCC42416에 대해서는 항곰팡이성을 나타내었다. 나아가 이들 화합물들은 항산화성과 항응고 활성도 나타내었다.

  • This study was separated and identified prostaglandin from garlic by TLC, HPLC, and Gc-Mass. In this experiment aimed at researching the effects of garic on body weight, and serum lipid, protein and glucose in male rats. The male rats applied in this work were 42 of Sprague-Dawley strain. In addition to basal diet, the worker administrated 4 groups of the experimental rats solutions which were 0.2 and 0.4ml of raw garlic juice, and of etanol garlic extract with together 2.5% cholesterol solution solved by corn oil for 8 weeks respectively. These results were as follows. 1. Separated and identified of Prostaglandin from garlic. 2. The growth rate of body weight and food efficiency ratio(FER) appeared to be more increased in the experimental groups administrated ethanol garlic extract than raw garlic juice. 3. The content of serum total cholesterol apperaded to be decreased in the experimental group administrated 0.4ml of ethanol garlic extract. 4. The level of serum HDL-cholesterol had a tendency to be more increased in all the experimental groups administrated garlic than control group. 5. The level of serum glucose appeared to be decreased in all the experimental groups administrated garlic, particularly ethanol garlic extract.

  • 마늘은 오랫동안 그 가치가 높이 평가되고 있으며 약용, 항균 및 살균효과적인 특성으로 인해 실제로 사용되어오고 있다. 본 연구는 마늘추출물의 천연식품보존제 개발가능성을 알아보기 위해 수행되어졌으며 신선한 마늘추출물과 이를 증류수로 희석한 마늘추출물들을 사용하여 6종의 식중독균 즉, S. aureus, E. coli, S. typhimurium, V. parahemolyticus, B. subtilis, L. monocytogenes들에 대한 감수성검사를 실시하였고 그 결과를 그람양성균 치료에 사용되는 Vancomycin과 그람음성균 치료에 사용되는 Imipenem을 대조로하여 이들 균주에 대한 항균력과 비교하였다. 마늘추출물에서 6균주 모두에 대해 강한 감수성을 보이거나 혹은 중등도의 감수성을 보였는데 V. parahemolyticus만은 마늘추출물의 원액에서만 항균력이 나타났고 희석한 농도에서는 항균력이 없었다.

  • Ammonium- and potassium-loaded zeolite (NK-Z) and other four kinds of environmental friendly fertilizers/agents were applied to characterize their effectiveness on garlic (Allium sativum L.) growth and soil amelioration. Selenium dioxide ($SeO_2$) and germanium dioxide ($GeO_2$) liquid treatments significantly increased selenium (Se) and germanium (Ge) contents in garlic stems, garlic cloves and clove peels. In soil treated with ZBFC, Se contents in garlic stems, cloves, and clove peels was 13.89-, 12.79-, and 10.96-fold higher, respectively, than in the controls. The inorganic contents of plants grown in soil treated with functional strengthened fertilizers were also higher than in plants grown in control soil. Soil treated with arbuscular mycorrhizal fungi (AMF) agents exhibited significantly greater spore density and root colonization rate than in untreated soil. The density of chitinolytic microorganisms in soil treated with colloidal chitin was also significantly higher than in untreated soil. The cation exchange capacities (CEC) in ZAFC-, ZBFC-, and ZBF-treated soils was 16.05%, 8.95%, and 8.80% higher than in control soil 28 weeks after sowing.
