  • Attempts were made to determine the effects of 5-Korean wild vegetabel consumptions on blood glucose leveles and orgen-energy metabolisms in streptozotocin-induced diabetic rats. The 5-Korean wild vegetables were : Cassia tora L.(C.t), Lycium chinese Mill(L.c), Trichosanthes kirilowii Max(T.k), Polygonatum odoratum var. Pluriflorum Ohwi(P.o) and Arctium lappa L(A.l). Sixty male Spargue-Dawley rats(160-220g) were induced diabetes mellitus by streptozotocin injection into the tail vein and were devided into 6 groups : a diabetic control and 5-experimental groups. All groups of the rats were fed on a AIN-76 diet, and the 5-experimental groups were fed with each wild vegetable (10%) for four weeks. An increased tendency in body weight of all the groups was observed and the tendency was more significant in L.c, T.k. and P.o. groups. The organ weight of liver and kidney were higher in L.c. and A.l. groups and lower in T.k. group which has shown the improvement from diabetes. Plasma glucose levels were markedly decreased from the 1st week in C.t, T.k. and P.o. groups and the tendency has lasted throughout the four weeks experimental period. The consumption of P.o. has decreased plasma cholesterol level while any significant difference was not seen in plasma protein levels from all the experimental groups. The level of plasma triglyceride was decreased in P.o. group and the levels of plasma free fatty acids were also significantly lower in P.o. and T.k. groups. The liver protein levels were significantly higher in P.o. and T.k. groups and these two groups also showed the negative or relatively small amount of urinary glucose excretion. The experimental group of T.k. has revealed the decreased level of muscles protein and the increased level of muscle glycogen. The 5-Korean wild vegetables contained dietary fiber and 9-analyzed minerals comparable to the ordinary use vegetables.

  • This study analyzed the chemical characteristics and physiological activity of five kinds of fresh vegetables produced in trees in early spring and tried to use them as basic data for wild vegetable producers and processed food manufacturers using wild vegetables. The crude protein, minerals, ascorbic acid, folate, total phenol, total flavonoid, DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity and ACE (angiotensin converting enzyme) inhibitory activity were determined. Five spring wild vegetables contain high protein and phosphorus, indicating that they are useful food ingredients as sources of protein and phosphorus. Vitamin C content was high in R. venicifera and C. sinensis shoots, and in particular, R. venicifera and A. cortex shoots have high folic acid (folate) contents of 1,903.91 ug% and 1,525.35 ug%, respectively, which is considered a good food for folic acid intake in spring. The total phenol content was between 0.52% and 1.27%, and it was the highest in C. sinensis of 1.27%, followed by the order of R. venicifera, A.cortex, K.pictus, and A. elata, which tended to be consistent with the total flavonoid content. As for DPPH radical scavenging ability, C. sinensis (55.93%) showed the highest activity, and ACE inhibitory activity showed the highest activity in A. cortex (88.04%).

  • 산채류 종자는 주로 농가의 자가 채종으로 생산되고 있다. 농가에서는 종자만을 생산하기 위해서 산채를 재배하지 않으며, 대체로 산채를 수확한 후 채종하는 실정이다. 하지만 종자생산을 위해서 생채나 나물을 언제까지 수확해야 하는지에 대한 한계기 설정이 불분명하다. 따라서 전북농업기술원 허브산채시험장에서는 개미취와 섬쑥부쟁이는 5년생, 곤달비는 3년생 묘목을 이용하여 종자생산을 위한 적정 생채수확 한계기를 설정하고자 시험을 실시하였다. 55% 차광막을 설치한 노지 재배포장에서 생채 수확 한계기를 각각 2020년 4월, 5월, 6월까지로 두어 한계기별 생채 수량, 상품 수량 및 상품율과 개화 시기, 개화율 및 결실률 등을 조사하였다. 개미취의 생채 상품율은 수확 한계기가 늦어질수록 다소 떨어지는 경향이었으며, 개화 시기는 무처리와 4월까지 수확은 동일하였으나, 5월, 6월까지는 수확 한계기가 늦어질수록 지연되었다. 개화율은 대부분 10% 미만이었으며, 5월과 6월까지 생채를 수확한 경우는 추대 및 개화가 거의 되지 않았다. 섬쑥부쟁이는 생채를 6월까지 수확하면 4월까지 수확한 경우보다 약 2배 이상의 생채를 얻을 수 있으나 상품율은 확연히 떨어졌다. 개화 시작은 무처리와 4월까지 수확이 타 처리에 비해 빨랐으나 개화종은 시기에 상관없이 비슷하였다. 또 4월까지 생채를 수확한 경우 무처리보다 개화율, 결실률이 더 높았다. 5월 이후 수확은 생육 부진으로 이어져 개화 및 결실률이 매우 떨어졌다. 곤달비는 개미취와 섬쑥부쟁이에 비해 생채 수확 한계기가 늦어질수록 상품 수량이 눈에 띄게 증가하였으며, 처리 간 추대 시기도 차이는 없었다. 개화율은 5월 수확 이후 낮아졌으며, 결실률은 6월 이후에 급격히 떨어졌다. 따라서 채종을 위해서는 차광재배 시 개미취와 섬쑥부쟁이는 생채 수확시기를 4월 하순, 곤달비는 5월 하순까지로 한정해야 할 것으로 판단된다.

  • The objective of this study was to investigate the contents of some minerals in vegetable foods by a highly sensitive Neutron Activation Analysis. Chinese Chives, Amaranth, Mugwort, Ginger, Garlic, Root of bellflower, Cultured Duduk, Wild Duduk and Cortinellus-edodes were chosen as experimental materials for this study. The contents of potassium, copper, molybdenum, and bromum were 7099.1mg%, 104.8 ppm, 45.4ppm and 40.4ppm in Chinese Chives. Chinese Chives, Amaranth and Mugwort were more abundant with iron, coppr and cobalt other than vegetable foods. The ratio of sodium to potassium for Chinese Chives was 1 to 796, for Mugwort : 1 to 147 and for Garlic : 1 to 148. As the Neutron Activation Analysis Technique was able to detect gold, samarium, bromum, lanthanum and scandium from vegetable foods, this technique is very useful to analyse the infinitestimal elements in foods.

  • The purpose of this study was to evaluate the antioxidative potential of Korean wild leaf vegetables in vivo as well as in vitro. The antloxidative activities of Pleurospemum kamtschaticum, Aderophora remotiflor and Aster gfheni were evaluated as a reference for Spinacia oleracea. Fifty rats were find either a control diet or one of several vegetable diets for 4 weeks. The level of thiobarbituric acid reactive substance (TBARS) and the activity of catalase and superoxide dismutase (SOD) in the liver were compared. The levels of total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG) in plasma were also compared. Also, the contents of $\beta$-carotene, vitamin C, vitamin E and total phenolic compound, including flavonoid and thiobarbituric acid (TBA) value using linoleic acid model system, were measured in Korean wind leaf vegetables. The TBARS values of Aderophora remotiflor and Aster giheni tended to be lower than that of Spinacia olerncea. The SOD activity of Artrr glheffi was significantly higher than that of Spinacia oleracea and reached 265% that of the control animals, whereas there was no difference between the control animals and the vegetable diet animals in terms of catalase activity. Compared to the control animals, TG and TC levels were significantly solver and showed a lower artheriosclerotic index. TBA values of Pleurospemum Kamschaticum and Aderophora remptiflor were only 18% of control value. TBA value of Spinacia olerucra was 41% of control value. These results suggest that Aderophora remotinor and Aster glheni could have antioxidative potency in vivo as well as in vitro and potential value far functional flood to improve the plasma lipid profile. flavonoid and phenolic compounds could be the major contributing factor in the antioxidative potential of Aderophora remotiflor and Aster glheni.

  • On the basis of the reported agriculturally valuable phenotypes resulted from ectopic overexpression of Arabidopsis vacuolar $H^+$-PPase (AVP1), we generated the Chinese cabbage lines expressing AVP1 which then subjected to salt stress to determine the AVP1 expression if it consistently confers the capability for increasing biomass and enhancing tolerance to salinity in other species. Collectively, here we demonstrate that the transgenic young plants show more vigorous growth and higher tolerance to salt stress than wild-type ones. Increased biomass phenotype by AVP1 expression was supported by comparing fresh and dry weights of transgenic and wild type plants grown under normal condition, while higher salt tolerance trait was confirmed by tracing the kinetics of photosystem II quantum yield and DAB-staining under gradually intensified salt stress induced by MS salt or NaCl, followed by normal condition.

  • Aralia elata is found in mountain areas all over Korean peninsula. Aralia elata is the scientific name for Japanese angelica tree. The tree belongs to the family Araliaceae, commonly known as ginseng family. Bud sprouts from apical shoot tip of the plants are rich in flavor and thus mainly used for both folk medicine and vegetable. The stalks with apical buds are gathered in the early spring and planted in sandy soil or water in the greenhouse. The sprouting buds are then collected and sold as fresh vegetable. Although the plants have been used for food, they have been cultivated in a very small scale. In spring, local farmers just go around mountain areas to search the trees and gather the stalks as much as they get and sell them to the market. No conservation efforts have been made to stop the exploitation or to save the dwindling population. We tried to provide local farmers with the plants that may be used as an alternative to stalks from wild populations. This will bel! p conserve the wild populations. However, it is hard to propagate them either by conventional cuttings or by seed germination in a short period of time. Mass propagation using tissue culture systems have shown a great promise with several woody plants. Recently we developed a mass propagation technique via somatic embryogenesis system using mature and/or juvenile explants for Aralia elata. Several factors affecting somatic embryogenesis system including SE(somatic embryo) induction, embryogenic callus proliferation, SE germination, plant regeneration and transplanting to field frill be presented. And some problems arising for the somatic embryogenesis system will be also discussed.
