  • Garlic(Allium sativum L.) is one of the oldest cultivated plants and has been used throughout the world as food supplement and folk medicine for thousands of years. In modem times a number of garlic derived products are introduced on the market as health food supplement in ever growing scale. In 1844 German chemist Wertheim investigated the garlic first time chemically and thereafter many kinds of organosulfur compounds were isolated and their biological activities were elucidated scientifically. The main biological activities are antibacterial, antifungal, antithrombotic, cholesterol-lowering, antineoplastic and hepatoprotective activities. Chemical works as well as therapeutic and preventive effects of garlic are reviewed.

  • The aim of this was to investigate whether the regular consumption of kimchi influences the iron status (RBC , Hb, Ht, MCH, MCV, MCHC, transferrin , serum iron, and ferritin) in volunteers. Healthy male adults(n=12) took part in the study subdivided into the control Ⅰ-phase(for 2weeks), kimchi-phase (for 4 weeks), and control Ⅱ-phase(for 2 weeks). In addition to their normal diet, participant consumed 300g of lactic acid fermented Chinese cabbage kimchi daily for four weeks. In the control Ⅰ and control Ⅱ phases, the participants kept up their normal diets without consuming any fermented foods. Dietary intakes were recorded for 3 consecutive days in each phase, with the aid of household measures. Every two weeks. blood specimens were analysed. Significant differences(p<0.05) between the phases were found in MCHC, and transferrin in blood were not significantly changed during kimchi consumption. However, serum iron and ferritin levels were significantly increased(p<0.05) during kimchi consumption, achieving the highest levels in the fourth week of the kimchi components(ascrobic acid, sulfer compound, organic acid, capsaicin, gingerol , allicin). Because of lacticacid fermented kimchi's potential to prevent anemia , the consumption of this food can be recommended.

  • The purpose of the paper is to explore the current knowledge on the nutritional evaluation, cholesterol-lowering effect and antitumor activity of kimchi and its ingredients(Korean cabbage, garlic, red pepper powder, ginger and onion). Kimchi contains high contents of nutrients such as vitamins(ascorbic acid, $\beta$-carotene and vitamin B complex), minerals(calcium, potassium, iron and phosphorous), essential amino acids and dietary fiber. Kimch also contains high levels of lactic acid bacteria, allicin, capsaicin, organic acid, phenol compounds, flavonoid and sulfur compounds. The dietary fiber and lactic acid bacteria isolated from kimchi are effective in improving intestinal microflora of human. Isoluble dietary fiber shows anticancer activity, but soluble dietary fiber shows hypocholesterolemic effect. Lactic acid bacteria isolated from kimchi acts as a hypocholesterolemic or anticancer agent. A major ingredient of kimchi is mainly cruciferous and allium family vegetables, which were also reported to prevent cancer and atherosclerosis. It is suggested that kimchi is important not only as one of the traditional fermented Korean food but also as therapeutic agent for carcinogenesis and hypercholesterolemic state.

  • Aqueous extracts of garlic (Allium sativum) preparation were prepared after the samples were exposed to various heat treatments. A quantitative assessment of antimicrobial activities was carried out by determining the minimum inhibitory and microbicidal concentrations (MICs and MMCs) of the various extracts against some selected bacteria and fungi. The antimicrobial activity of garlic decreased as the heating temperature increased. This fact implies that alliinase may be the most critical rate-determinant to produce the activity when garlic is heated.

  • Garlic (Alium sativum L.), originated in the Kirghiz region of Central Asia, is oneof the oldest cultivated plants. It has reached Europe via Egypt in the days of Pharaohs. Since then, the legendary medicinal properties attributed to garlic have attracted human interests for thousands of years. However, the research on the medicinal effect of garlic, mostly on this anticarcinogenic actions has been systematically performed only for the last tow or three decades. Many researches have proven that garlic inhibits neoplasia elicited by chemical carcinogens using in vitro or in vivo experimental systems. Attention has recently been focused on assessing the therapeutic or chemopreventive measures of garlic compounds against carcinogenesis in animals. The active principles of he garlic extract, mainly the sulfur compounds and their derivatives have been deeply scrutinized into their chemical, functional and medicinal properties.

  • This paper introduces the physicochemical characteristics of garlic shoots investigated in the 8 areas of Namhae, Gohyeon-myeon (GHM), Nam-myeon (NM), Samdong-myeon (SDM), Namhae-eup (NHE), Seo-myeon (SM), Seolcheon-myeon (SCM), Idong-myeon (IDM) and Changsoen-myeon (CSM). The moisture was $80.15{\pm}0.37{\sim}83.87{\pm}0.15g/100g$. The crude protein and lipid were $1.59{\pm}0.02{\sim}2.25{\pm}0.09g/100g$ and $0.35{\pm}0.01{\sim}0.48{\pm}0.03g/100g$, respectively. Ash was $0.65{\pm}0.03{\sim}0.71{\pm}0.03g/100g$. In addition, the total levels of phenol and flavonoid were searched as $33.02{\pm}1.78{\sim}58.41{\pm}1.08mg/100g$ and $11.60{\pm}3.36{\sim}23.95{\pm}2.04mg/100g$, respectively. The garlic shoots in IDM, where the highest total chlorophyll level detected as $170.58{\pm}1.04{\mu}g/g$ and in CSM, where the lowest total chlorophyll level investigated as $116.65{\pm}0.00{\mu}g/g$, were unveiled. The mineral elements (S, Ca, Fe, K, Mg, Na, Mn and Zn) were analyzed by ICP-OES, and K was the most highly contained mineral with $7257.0{\pm}87.9{\sim}10070.0{\pm}9.7mg/kg$. Significant feature of garlic shoots in IDM and NHE was that the total amounts of mineral were relatively higher than other regions as 21,143.5 mg/kg and 20,581.2 mg/kg, respectively. The cultivating regions were revealed as the one of important matters with the level of allicin ($78.03{\pm}6.15{\sim}203.43{\pm}18.47mg/kg$). In particular, the level of allicin of garlic raised in SDM ($203.43{\pm}18.47mg/kg$) was approximately 2.2~2.6 times higher than those in CSM ($92.86{\pm}8.70mg/kg$) and SCM ($78.03{\pm}6.15mg/kg$). The sulfur compounds content of diallyl trisulde was remarkably higher, especially the garlic shoots in IDM with $830.62{\pm}14.69{\sim}1281.10{\pm}27.71mg/kg$.

  • In 1944 Cavallito and Bailey first extracted an essential oil, a powerful antibacterial principle, from the garlic and named it allicin. Later Stoll and Seeback elucidated that allicin was produced from alliin by the enzymatic action of arinase. Damaru observed the depressor responses following intraperitoneal administration of garlic juice in cats. And Thiersch presented evidence that garlic had a protective action against experimental arterosclerosis in cholesterol-fed animals. On the other hand it was also reported that anemias were caused by long-term ingestion of garlic as a result of reduction in hemoglobin and RBC. From the experiment in which the effect of garlic on the blood sugar level was studied, Lee insisted garlic elevated blood sugar level. However, August and Jain claimed that hypoglycemia was induced by garlic administration. Recently Bordia and Bansal suggested that essential oils extracted from onion and garlic have a strong preventive effect on hyperlipemia and prolonged coagulation time resulted from fat-feeding. Furthermore Bordia et al indicated that garlic exerted a strong fibrinolytic activity. In early 1920 s Sugihara reported that essential oil of garlic not only decreased arterial blood pressure but also had a paralytic effect on the isolated heart and intestinal strip of animals. The present study was proposed to investigate the effect of garlic juice and the mechanism of its action on the motility of the isolated rabbit duodenum. The motility of the isolated duodenum was recorded on polygraph by means of force transducer connected with Magnus apparatus. And the isolated duodenum was separtely pretreated with $acetylcholine(5{\times}10^{-7}\;gm/ml)$, $pilocarpine(2.5{\times}10^{-6}\;gm/ml)$, $histamine(5{\times}10^{-6}\;gm/ml)$ and barium $chloride(2.5{\times}10^{-5}\;gm/ml)$ in order to find out interations of these drugs with ASJ. The results obtained were as follows; At concentrations of 0.25%, 0.5% and 1.0% ASJ markedly inhibited contractions of isolated duodenum while tonus as well as contractility of the isolated intestine were decreased also with 0.5% and 1.0% ASJ. Since ASJ markedly abolished augmented motility of isolated intestine by histamine and partly reduced that by $BaCl_2$, it is strongly suggested that inhibitory action of ASJ on the intestinal motility is caused mainly by its antihistamine effect and partly by its direct action on the intestinal smooth muscle.
