  • An hydrocarbon alcohol and steroids were isolated from the hexane fraction of the extract from the seeds of Phaseolus radiatus L. And also a flavonoid was identified from the ethyl acetate and butanol fraction. The structure of the obtained compound were elucidated by spectroscopic methods (UV, IR, mass and NMR) and their physicochemical properties. As the results, triacontanol, stigmasterol, ${\beta}-sitosterol$ and vitexin were identified.

  • Four crop plant species were tested to assess an ecotoxicity in arsenic-amended soils. Test plants were Sorghum bicolor, Cucumis sativus, Triticum aestivum, and Phaseolus radiatus. The presence of arsenic decreased the root and shoot growths. Arsenite was more toxic than arsenate to all test plants. Root growths of Phaseolus radiatus and Cucumis sativus seem to be a good protocol to assess ecotoxicity of soils contaminted by arsenic.

  • Effect of plant hormones on the leaf senescence of mung bean (Phaseolus radiatus) was investigated by measuring the changes of reducing sugar contents and invertase isozyme activities in detached leaves treated with NAA, $GA_3$ or BA. During dark-induced senescence, reducing sugar contents in the detached leaves increased temporarily at 4 d, thereafter decreased rapidly and reached minimum values within 7-14 d. The pattern of soluble acid invertase activity in the senescing leaves kept in the dark was similar to that of reducing sugar accumulation, whereas the activities of alkaline and extracellular invertases were not significantly changed during leaf senescence. Therefore, these results suggest that soluble acid invertase, but not alkaline and extracellular invertases, induces the accumulation of reducing sugar during leaf senescence of mung bean plants. Exogenous NAA application had little or no effect in the increase of soluble acid invertase activity during dark-induced senescence compared to the control. However, exogenous applications of $GA_3$ and BA led to the increase of soluble acid invertase activity in the senescing leaves. Particularly, BA application was very effective in enhancing the activity of soluble acid invertase as well as in delaying chlorophyll breakdown during dark-induced senescence. These results suggest, therefore, that BA regulates the activity of soluble acid invertase, which leads to the accumulation of reducing sugar, and the stability of photosynthetic apparatus to delay leaf senescence.

  • Objectives : This study is designed to clarify whitening, anti-inflammatory effect of fractions extracted from the mixture of Phaseolus radiatus L. and ethanol. Methods : In this experiment, we were intended to reveal whitening, anti-inflammatory effect of fractions extracted from the mixture of Phaseolus radiatus L. and ethanol. The whitening activity was confirmed by UV blocking activity, tyrosinase inhibiting activity, and melanin formation inhibiting activity. Anti-inflammatory activity is confirmed by measurement of cytotoxicity level by MTT assay and measurement of Cytokine expression, which is the main mediator of inflammation reaction. Results : As a results, overall activity was high in the ethyl acetate fraction. Tyrosinase inhibitory activity was less than 20% at all concentrations, but the activity to inhibit melanin self-production was higher than that of ethyl acetate fraction at $32.19{\pm}2.79%$ at $100{\mu}g/m{\ell}$. And ethyl acetate fraction had a relatively high UV blocking activity. In the anti-inflammatory test, the concentration-dependent activity was shown, and the chloroform and ethyl acetate fractions showed significant NO production inhibitory activity. Cytokine expression was superior to that of the final stage of B cell differentiation, and cell viability was over 80% except for the chloroform fraction at the concentration of $200{\mu}g/m{\ell}$. Conclusions : The results of this experiment confirmed the whitening effect and anti-inflammatory effect of Phaseolus radiatus L.'s extracts and fractions and report the possibility of application as external medicine.

  • ATP contents of soybean(Glycine max Merrill) and mungbean (Phaseolus radiatus L.) seeds being germinated with Hoagland solution at $30^{\circ}C$ for 6 days were determined. In pregerminated seed, ATP contents in soybean and mumgbean were 11.4 and 63.0$\mu$g/g fresh seed respectively. During germination, the highest ATP content of soybean seeds was 550% of initial content on 2nd day and that of mungbean was 480% on 1st day after germination. ATP content in cotyledon of soybean and mungbean were increased up to 4th and 1st day after germination respectively, thereafter both were decreased, but those in the root, including the hypocotyl, of both seeds were continuously increased with germination progress.

  • The soluble acid invertase ($\beta$-D-fructofuranoside fructohydrolase, EC 3.2.1.26) was isolated and characterized from the hypocotyls of mung bean (Phaseolus radiatus L.). The enzyme was purified to apparent homogeneity by consecutive step using diethylaminoethyl (DEAE)-cellulose anion exchange, Concanavalin (Con) A affinity and Sephacryl S-300 chromatography. The overall purification was about 148-fold with a yield of about 15%. The finally purified enzyme exhibited a specific activity of about 139 $\mu$mol of glucose produced mg-1 protein min-1 at pH 5.0 and appeared to be a single protein by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and nondenaturing PAGE. The enzyme had the native molecular weight of 70 kD and subunit molecular weight of 70 kD as estimated by Sephadex G-200 chromatography and SDS-PAGE, respectively, suggesting that the enzyme was composed of a monomeric protein. On the other hand, the enzyme appeared to be a glycoprotein containing N-linked high mannose oligosaccharide chain on the basis of its ability to bind to the immobilized C on A. The enzyme had a Km for sucrose of 1.8 mM at pH 5.0 and maximum activity around pH 5.0. The enzyme showed highest enzyme activity with sucrose as substrate, but the activity was slightly measured with raffinose and cellobise. No activity was measured with maltose and lactose. These results indicate the soluble acid invertase is a $\beta$-fructofuranosidase.

  • In order to investigate whether or not the alcohol-treated rat liver cells can be protected by Korean Citrus junos and medicinal herbs, We compared the serum biochemistry of rats administered both alcohol and the complex of Korean Citrus junos and medicinal herbs to control rats treated with alcohol alone. The activities of Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) in the citron 3 (Citron 3, less mellowed citron which was ripened for three months)+Phellinus linteus, Alnus japonica, Dendropanax morbifera and citron 4 (Citron 4, completely mellowed citron which was ripened fer four months)+Phaseolus radiatus, Cordyceps militaris group were significantly low when compared with the negative control group (p<0.05). The levels of triglyceride (TG) in all experimental groups were significantly lower than the negative control group (p<0.05). The concentrations of total cholesterol in the citron 3+Phellinus linteus, Atnus japonica, Dendropanax morbifera and citron 4+Phaseolus radiatus, Cordyceps militaris, Phellinus linteus were lower than the negative control group (p<0.05). The activities of alcohol dehydyogenase (ADH) in all experimental groups were significantly high when compared with the normal control group (p<0.05). These results suggest that the complex of Korean Citrus junos and medecinal herbs could be an excellent candidate for protecting vat liver cell damage induced by alcohol.
