  • Among 100 species in 54 families of plants tested, leaf extracts from Allium cepa, Allium sativum, Malussieboldii, Reynoutria japonia and Rheum coreanum were inhibitory on mycelium growth of phytophthora spp.. Especially, Allium sativum and Malus sieboldii were strongly inhibitory. Allium sativum, Malussieboldii and Rhem coreanum were strongly inhibitory on zoosporangium germination of P. capsici. Malus sieboldii only were strongly inhibitory on zoosporangium germination of P. nicotiana and P. infestans.And Malus sieboldii were strongly effected on disease control of these pathogens. These results indicate the possibility of finding antagonistic plants in the nature for the control of certain pathogens in soil.

  • High performance liquid chromatographic (HPLC) analysis of mycelia of Sclerotium rolfsii grown in broth medium supplemented with garlic (Allium sativum) and onion (Allium cepa) was carried out to estimate qualitative and quantitative changes in phenolic acids. Several phenolic acids, such as gallic, chlorogenic; ferulic, o-coumaric and cinnamic acids were detected in varied amounts in mycelia grown on such media as compared to control. Phenolic acids represents a wide range of secondary metabolite found in the cells of plants and microbes including fungi. The growth characters of S. rolfsii in various supplements also varied from thin and transparent to thick and opaque.

  • BACKGROUND: Garlic (Allium sativum) contains polyphenols and sulfur compounds that are recognized as antioxidant, antithrombotic, anticancer, antibacterial, antimicrobial, nematicidal, and insecticidal activity. For this reason, the Environmentally-friendly Agriculture Promotion Act allowed the garlic extract as commercial biopesticide material for crop protection, nine commercial biopesticides containing A. sativum extract have been marketed in Korea. METHODS AND RESULTS: The determination of allylmethyl sulfide (AMS), dimethyl disulfide (DMDS), and dipropyl sulfide (DPS) in biopesticides containing A. sativum extract was developed and validated by gas chromatography (GC) mass spectrometry (MS) with head-space sampler. The developed method was validated, and the limit of quantification (LOQ) and recovery rates of AMS, DMDS, and DPS were 0.08, 0.32, and 0.09 mg/L and 90.3-91.3, 86.2-88.3, and 87.6-89.5%, respectively. From the nine commercial biopesticide samples, contents of AMS, DMDS, and DPS were analyzed using the developed method and results showed

  • 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.

  • Allium sativum (Family Amaryllidaceae or Liliaceae) is used worldwide for various clinical uses like hypertension, cholesterol lowering effect, antiplatelets and fibrinolytic activity etc. Due to these common house hold uses of Allium sativum, as a herbal supplements, and failure of patients to inform their physician of the over-the-counter supplements they consume leads to drugnutrient interactions with components in herbal supplements. Today these types of interactions between a herbal supplement and clinically prescribed drugs are an increasing concern. In vitro studies indicated that garlic constituents modulated various CYP (cytochrome P450) enzymes. CYP 3A4 is abundantly present in human liver and small intestine and contributes to the metabolism of more than 50% of commonly used drugs including nifedipine, cyclosporine, erythromycin, midazolam, alprazolam, and triazolam. Extracts from fresh and aged garlic inhibited CYP 3A4 in human liver microsomes. The in vivo effects of garlic constituents are found to be species depended and the dosing regimen of garlic constituents appeared to influence the modulation of various CYP isoforms. Studies have indicated that the inhibition of various CYPs by organosulfur compounds from garlic was related to their structure also. Studies using in vitro, in vivo, animal and human models have indicated that various garlic constituents can be the substrates, inhibitors and or inducers of various CYP enzymes. The modulation of CYP enzyme activity and expression are dependent on the type and chemical structure of garlic constituents, dose regime, animal species and tissue, and source of garlic thus this review throws light on the possible herb drug interaction with the use of garlic.

  • Gartic bulblets were planted to investigate the effect of some different cultivating conditions on the growth and bulb formation of the garlic plants (Allium sativum L.) Two different conditions namely perfect and imperect aerobic condition, and 3 different fertilizer levels was made. The split plot design was adopted for this experiment. 1) For the growth rate, under the imperfect aerobic condition, the plant height was more increased than that of perfect aerobic condition no relation to the fertilizer levels. 2) With respect to the fresh weight of garlic, the similar tendency to the growth rate was observed, but dry weight was did not. 3) The uptake of phosphorus was found to be increased in the imperfect condition. It could there be concluded that imperfect aerobic condition seems to be much favorable condition than the perfect aerobic condition to the development of garlic bulbs.

  • This study investigated the effect of allium vegetable intake on the storage and utilization of energy substrates before, during, and after exercise in tissues of rats. Ninety mts were fed either a control diet or a diet with added allium sativum (AS), allium cepa (AC), allium fistulosum (AF), or allium tuberosum (AT) for 4 weeks and then subdivided into 3 groups: before-exercise (BE) during-exercise (DE) after-exercise (AE). The DE group exercised on treadmill for 1 hour just before being sacrificed at the end of the 4th week of the dietary treatment Rats in the AE group were allowed to recuperate for 2 horns after being exercised like the DE group. Pyriooxal 5'-phospwe (PLP) levels were compared in plasma, liver and skeletal muscle of rats. There was no difference between AS animals and control animals in plasma PLP levels regardless of exercise. The plasma PLP levels of AC animals were higher than those of control animals before exercise but this PLP was decreased with exercise and lower than that of control animals after exercise. The plasma PLP levels of AF animals were higher than those of control animals during exercise but there was no difference before and after exercise. The plasma PLP levels of AT animals were higher than those of control animals regardless of exercise. Compared to those of control mts, the PLP levels of liver and muscle were significantly lower in AS, AC, AF and AT mts before exercise. The levels of liver PLP were significantly decreased in control mts while not changed in AS, AC, AF and AT mts during exercise. The levels of liver PLP tended to decrease in AS, AC and AF mts after exercise. The levels of muscle PLP were significantly decreased in control rats, while not changed in AS, AC and AF mts during exercise. The levels of muscle PLP were decreased in control mts but not changed in AS, AC and AF mts after exercise. Thus, it is suggested that the changes of PLP concentrations in plasma and tissues induced by exercise are affected by allium vegetable diet and demonstrated that allium vegetable intake induced an alteration in the redistribution of PLP among tissues.

  • Ninety rats were fed either a control diet or one of several allium vegetable diets (allium sativum (AS), allium cepa (AC), allium fistulosum (AF) or aliium tuberosum (AT) for 4 weeks and were separated into 3 groups : non-exercise (NE), exercise (EX), and exercise and recuperation (ER), The EX group was exercised on a treadmill for 1 hour just before sacrifice at the end of 4th week of diet intake and the ER group was recuperated for 2 hours after exercise. The levels of glucose (GLU), (PRO), triglyceride (TG), free fatty arid (FFA) and hemoglobin (Hb) were compared in plasma. In the U group, GLU levels of AS and AC tended to be higher than those of the control group. There were no differences in GLU levels between the control group and the allium vegetable groups in EX, whereas GLU levels of AS, AF and AT tended to be lower than that of control group in ER. There were no differences in PRO among the groups NE, EX and ER. TG and EEh levels of AS, AC, AF and AT tended to be lower than those of the control group in NE, EX and ER. Hb levels of AS, AC, AF and AT were lower than that of the control group in U and ER and tended to be lower than that of EX. These results suggest that allium vegetable diets have the potential to enhance the capacity to oxidize fatty acid and to recover triglyceride after recuperation, although there is compensation among stored fuel utilization during exercise
