  • L-PHA, a lectin having lymphoagglutinating activity but devoid of erythroagglutinability which is contained in Korean white kidney bean (Phaseolus vulgaris L.), was isolated and purified through several techniques such as ion exchange chromatography, hydroxyapatite column and affinity chromatography. Purified L-PHA was identified as a single band by polyacrylamide disc gel electrophoresis. The molecular weight of the L-PHA was estimated about 125, 000 daltons by polyacrylamide gel electrophoresis and it was turned out having one subunit (probably dimer of the Yachnin's model) of Mr~60, 000. Immunochemical studies also tried and these results reconfirmed the purity of this L-PHA.

  • Determining the optimal mixing ratio of pumpkin, water, glutinous rice powder, red bean, kidney bean in preparing Hobakjook has been attempted and on the basis of it, Hobakjook with glutinous rice powder was set to be A group, and the one that glutinous rice powder was replaced by brown glutinous rice powder for the purpose of enhancing preference and nutrition was set to be B group. A group and B group with additional 0%, 5%, 10%, 15% perilla powder of pumpkin weight was labeled as Al-A4 and Bl-B4 respectively, and then analyzed nutritionally. Optimal material mixing ratio and preference was investigated by use of sensory evluation and instrumental test. As a result, the optimal material mixing ratio was determined as pumpkin 400 g, water 60 cc, glutinous rice powder 40 g, red bean 30 g, kidney bean 30 g, salt 4 g, sugar 10 g. In sensory evaluation significant difference (P < 0.05) was shown among the samples in color., flavor.1, falvor. II and overall quality. And A3 in viscosity, A2 in color, A4 in sweetness, B2 in flavor 1, Al and B2 in flavor 11, and B2 in overall quality was preferred most. Instrumental measurement shows that B4 in viscosity and A4 in sweentness was highestly recorded and showed significant difference (p<0.05). As the addition of perilla powder increased, the viscosity and sweetness was increased. In color measurement A4 in L value, A3 in a value, and Bl in b value was highestly recorded. And as perilla powder was added, L value and a value was increased while b value was decreased. Color in sensory evaluation was significantly correlated to b value in instrumental measurement. In summary, Hobakjook with brown glutinous rice was superior to the one with glutinous rice in preference and proximate composition, and as the addition of perilla powder was increased, proximate composition was increased but preference was rather decreased, and Hobakiook with 5% addition of perilla powder to brown glutinous rice powder was preferred most.

  • Pear black necrotic leaf spot (PBNLS) on pear trees (Pyrus pyrifolia) is caused by a Korean isolate of Apple stem grooving virus (ASGV-K). Yellow spots were detected in Phaseolus vulgaris (kidney bean) and Chenopodium quinoa which were grown near the diseased pears in year 2000 through 2003. The ASGV-K, the causative agent of PBNLS, was detected from the symptoms of the diseased kidney bean plant and C. quinoa. ASGV-harboring fungi were also isolated from symptomatic plants and from soils surrounding the infected plants. The ASGV-harboring fungus was identified and characterized as Talaromyces flavus. Ecopathological studies showed that the number of ASGV-harboring fungi on the pear leaves was not correlated with differences in temperature or severity of symptoms. Additionally, there was no difference in fungus frequency among the orchard locations or different host plants. Although the frequency of fungi isolated from the soil was not affected by changes in temperature or location, the fungi occurred at higher densities in the rhizosphere than in the plants themselves.

Effects of a Dietary Supplement Consisting of Phaseolus vulgaris and Garcinia cambogia (RCA) on the Lipid Level and Body Weight (Phaseolus vulgaris, Garcinia cambogia (HCA)가 함유된 다이어트 식이 조성물의 체지방 개선 및 체중 변화에 미치는 영향)

  • In this study we examined effects of a new dietary supplement on the lipid level and body weight. The efficacy of this weight-reduction supplement, based on natural ingredients consisting of Phaseolus vulgaris, Garcinia cambogia, and microstalline cellulose, was investigated by randomized, placebo-controlled double-blind study. The 36 subjects were assigned evenly into weight-reduction supplemented (Active) and placebo groups (Placebo). The supplement could reduce the absorption of different types of sugar from the gastro-intestinal tract. A significant difference in weight reduction was shown in the active group (3.5 kg). Body composition measurements indicated that about 34% of fat loss in the active group could be achieved. These findings suggest that this dietary supplement could reduce body weight and fat gains, and its inhibitory effects might lead to obesity improvement.

  • The measurements of rubisco parameters are important in photosynthetic studies. In this experiment, we used photometric assay method to detect these major parameters, such as activity, carbamylation and amount of rubisco. The main advantages of this method are very simple and as sensitive as conventional methods which usually produce radioactive waste. In this study, with kidney bean (Phaseolus vulgatis L.) leaves grown at normal $CO_2$ (350ppm) and high $CO_2$ (650 ppm), we investigated the effect of $CO_2$ concentration on activation and carbamylation of rubisco by measuring the rubisco activity, carbamylation rate and amount of rubisco using a dual beam (334nm and 405nm) spectrophotometer, and analyzed the polypeptide profiles of rubisco by SDS-PAGE. When $CO_2$ concentration was raised from 350ppm to 650ppm, all parameters of rubisco were decreased : $41.2{\mu}M/m^2/s and 52.2{\mu}M/m^2/s$ to $27.4{\mu}M/m^2/s and 46.1{\mu}M/m^2/s$ for initial and total rubisco activity, respectively ; from 79% to 58.9% for carbamylation rate ; from $1.94 {\mu}M/m^2$ to 1.58{\mu}M/m^2$ for amount of rubisco. These results suggests that the decrease in rubisco activity at high $CO_2$ was caused by carbamylation. The analysis of the preparation by SDS-PAGE showed two major polypeptides at 50 and 14.5 kD which were identified as the large and the small subunits of rubisco. There were no differences in the intensity compared high $CO_2$ to normal $CO_2$ in both 50 kD and 14.5 kD bands. We also found that these inhibitory effects of $CO_2$ were reversible. When high $CO_2$ was switched to normal $CO_2$, the parameters of rubisco changed were almost the same as normal rubisco parameters. These data provide an evidence that activity of rubisco was recovered by $CO_2$ concentration of 350 ppm.

  • In this study, we investigated the levels of glutathione (GSH) and its oxidized form (GSSG) in more than 40 kinds of plant materials including seedling plants, grains, vegetables, and processed foods. The glutathione contents in the seedling plants were ranged from 0 to $120{\mu}mol/100g$. In addition, the different levels of glutathione were observed within the same family and between species. In the case of marketed grains and vegetables, azuki and kidney beans of leguminosae contained the high levels of glutathione, whereas glutathione was scarcely detected in the processed bean foods (bean paste, soybean sauce, etc.). Overall, a higher GSH content in food may contribute to a higher added value.

  • Pulses are an annual leguminous crop yielding from one to twelve grains or seeds. This study was used eight pulses except for green beans. We evaluated the chemical characteristics of these raw pulses produced in Korea. The nutritional and functional contents such as moisture, carbohydrate, crude protein, crude lipid, ash, dietary fiber, minerals(Ca, P, Fe, Na, and K), vitamins (A, E, C, B groups, folic acid, and niacin), total polyphenol, carotenoid, and flavonoid containing isoflavone were investigated. As a results, all raw samples were shown the high levels of almost nutritional contents (especially, protein, fats, and fat-soluble vitamins). In addition, yellow soybeans, red bean, and kidney bean were high the contents of total polyphenol. Of the functional contents, three lands of the yellow soybeans were shown the high flavonoid. This study represent much to provide the fundamental nutrition and function data in pulses because they have significant nutritional and health advantages for humans.
