This investigation was conducted to observe changes of lipid components (phospholipids, free sterols, free fatty acids, triglycerides and estrified sterols) and fatty composition in diethyl ether extract and 86% MeOH extract from cotyledon and seedling axis of mung bean which were germinated in the dark at 25-$27^{\circ}C$ for 7 days. The total lipid contents in cotyledonn and seedling axis gradually decreased during germination. The triglyceride content in total lipid from cotyledon decreased and free fatty acid content increased, but triglyceride content from seedling axis decreased slightly and free fatty acid content decreased. Free sterol, esterified sterol and phospholipid content in cotyledon increased continuously, but their content in seedling axis dcreased slightly. The major fatty acids in mung bean were palmitic acid, linoleic acid and linolenic acid.

This study was conducted to investigate the isoflavone (daidzein and genistein) contents, and the antioxidative and fibrinolytic activities of red and mung beans. Daidzein was not found in either the red or mung beans. The genistein contents of the red and mung beans were 40.7 and 27.8 mg/kg, respectively. Both samples had very high electron donating abilities and SOD-like activities. Fibrinolytic activities were not detected in the crude mung bean extract, but fibrinolytic substances were purified or activated under various pH conditions and with heat treatments. With heat treatment at 100 $^{\circ}C$ for 10 min, the specific activity was increased 4.61 fold. This study revealed that, although red and mung beans were poor in isoflavone, they could be good sources for functional products due to their strong antioxidative activities and heat- and acid-resistant proteolytic abilities.

Phaseolus aureus (mung bean), Leguminosae, has been used as an antidote from the ancient time. Especially, it has been widely used for cleaning face and skin in oriental countries. Although several constituents such as fatty acids, phytoallexin and phaseol derivatives were reported in P. aureus and related species including seedlings, there has been a few report to describe its biological activity. Therefore, in this investigation, the ethanol extract from P. aureus was obtained and its biological activities including the antioxidative and anti-inflammatory activities were studied. The 70% ethanol extract from P. aureus showed dose-dependent antioxidative activity (52.3% inhibition at 4 mg/ml) against lipid peroxidation assay, while the extract did not show the inhibitory activity of superoxide radical formation. The extract also showed the topical anti-inflammatory activity against croton-oil and arachidonic acid induced mouse ear edema test (18-19% inhibition at 7.5 mg/ear) as well as mild inhibitory activity against picryl chloride induced delayed hypersensitivity in mouse. For investigating active principles, vitexin and isovitexin (apigenin C-glycoside) as flavonoids, and adenosine were isolated from the extract using silica gel chromatography. The actual contents of vitexin and isovitexin were found to be 3.7 and 2.4 mg/g extract, respectively. Vitexin and isovitexin showed the antioxidative activity. They showed the topical anti-inflammatory activity, although the activities were not potent compared to the reference compounds. These results suggested that vitexin and isovitexin may be, at least in part, the compounds contributing the antioxidative activity in vitro and the topical anti-inflammatory activity of P. aureus in vivo. All results of present study might be one of the scientific rationale in using mung bean for skin care from the ancient time.

In this study, as a result of exploring the physiological activity of plants useful for agriculture on various plant resources, it was possible to confirm an activity similar to auxin that promotes plant rooting in methanol extract of Cinnamon Bark (cortex of Cinnamomum cassia J.Presl). After separating the active body by applying column chromatography and HPLC to the CHCl3 active fraction obtained by solvent extraction for each polarity from the methanol extract of cinnamon bark, cinnamyl alcohol was identified through GC/MS analysis. By bioassay using cinnamyl alcohol standard and the active fraction separated and purified from the methanol extract of cinnamon bark, the rooting rate of mung bean seedlings of the cinnamyl alcohol standard was 290% compared with the untreated control at 134.2 ㎍/mL concentration, and the adventitious root formation activity similar to the rooting rate (268.6%; 100 ㎍/mL) of the active fraction was shown. In conclusion, it is believed that cinnamyl alcohol contained in methanol extract of Cinnamon Bark is the main compound that induces adventitious root formation in mung bean.

An examination of the kinetic properties of UDP-glucose, (1,3)-$\beta$-glucans (callose) synthase, from mung bean seedlings (Sorbus commixta cortex) shows that these enzymes have a complex relationship with UDP-glucose and various effectors. Fluorescence assay showed that deoxynojirimycin increased the inhibitory effect of (1,3)-$\beta$-glucan synthase in a concentration-dependent manner. The inhibitory effect of sakuranetin (34.34%) was higher than that of deoxynojirimycin (80.63%). Disk diffusion method revealed that sakuranetin inhibited the growth of Candida albicans to a 1.5 mm inhibition zone. These results suggest that sakuranetin, isolated from Sorbus commixta cortex extract, can be used as stable antifungal material.

Objectives : Green gram (mung bean) has a cold nature and has been known to detoxify against various side effects that belong to hot in nature. In particular, since it has the effect of detoxifying fever and detoxification to treat swelling, it was also used externally to treat febrile dermatological diseases such as erysipelas and rubella. This study was designed to determine whether green gram exhibits anti-inflammatory effects on contact dermatitis in mice. Methods : We investigated the effects of green gram extract (70% ethanol extract) on skin lesion, skin thickness and weights, melanin and erythema index and spleen body weight ratio in mice with contact dermatitis induced by repeated application of 1-Fluoro-2,4-dinitrobenzene. Results : Topical application of green gram extract ameliorates skin lesions of contact dermatitis such as scale and roughness induces by 1-Fluoro-2,4-dinitrobenzene. green gram extract also suppressed enlargement of skin thicknesses and weights significantly. In addition, green gram extract treatment also lowered erythema index significantly compared to those in the control group. In the histopathological observation, green gram extract prevented epidermal hyperplasia and hyperkeratosis in inflamed tissues. Finally, green gram extract did not affect changes in body weights and the spleen body weight ratio, unlike dexamethasone, which significantly prevented body weight gain and lowered the spleen body weight ratio. Conclusions : These results imply that green gram, which is known to have a detoxifying effect in Korean medicine, can be used in the treatment of contact dermatitis.

A examination of the kinetic properties of UDP-glucose : (1,3)-$\beta$-glucan (callose) synthase from mung bean seedings (Sorbus cortex) shows that these enzymes have a complex interaction with UDP-glucose and various effectors. Deoxynojirimycin increased the inhibitory effect of (1,3)-$\beta$-glucan synthase at the concentration-dependent manner by fluorescence assay. The inhibitory effect of Fr. 2-16 (97.15%) showed higher than that of deoxynojirimycin (80.63%). Fr. 2-3 inhibited the growth of the Candida albicans at 1 mm inhibition zone by disk diffusion method. These results suggest that Sorbus cortex extract can be used as a stable antifungal material.

This study was conducted with n-hexane extracts of sensitive plant Mimosa pudica, mexican poppy Argemone mexicana, panimarich Leucus aspara, water pepper Polygonum hydropiper and shialmutra Blumea lacera weeds against pulse beetle Callosobruchus chinensis (Coleoptera: Bruchidae) for protection of mung bean Vigna radiata grains. The $LC_{50}$ values of the weed extracts ranged from 4.5 to 6.4, 4.1 to 5.6 and 3.6 to 5.5 g/100 mL at 24, 48 and 72 hours of post treatment, respectively. The extracts showed 35 to 69% fecundity and 33 to 63% adult emergence inhibitory effect on the pest, and revealed 13 to 49% grain protection of mung beans. Insect mortality, fecundity and adult emergence inhibitory effects, and grain protection activity increased with increased concentration of the extracts. The shialmutra followed by water pepper extracts revealed better performances in fecundity and adult beetle emergence inhibitory effect compared to the other weeds. The findings proved that the n-hexane extracts of the five weeds are sources of botanical insecticides which may be used in the integrated management of C. chinensis.

The growth of weeds and some other plants has been considered to be inhibited by sicklepod(Cassia tora L.) sharing the habitat. The study was conducted, for the first time, to propose that this phenomenon is not only due to competition for physical and nutritional conditions but also due to allelopathy. In addition, autotoxicity of sicklepod was examined. The results are summarized as follows. 1. Rice sheath length reduced progressively from 18 % to 36 % with increasing the concentration of treating aqueous extracts of sickle pod seeds, but rice germination was not affected. In contrast, radish hypocotyl length was not reduced by the aqueous extract treatment but radish germination was significantly reduced by 66 % at 1 : 10 and 1 : 5 treatment. 2. Total chlorophyll contents in rice seedling decreased from 50 % to 65 % by treatment of seed aqueous extracts diluted from 1 : 50 to 1 : 5 ratio. 3. Aqueous extracts of sicklepod leaves significantly reduced hypocotyl length and fresh weight in radish and germination in rice, but mung bean was slightly affected by aqueous extracts only in fresh weight. 4. Volatiles from fresh, immature seeds with husk reduced the radish germination and seedling growth and radish root growth appeared to be more sensitive to the exposure to volatiles from fresh immature seeds than both germination and hypocotyl growth. 5. Volatiles from sickepod leaves inhibited germination and growth of radish, rice and mung bean, and seedling growth was more sensitive to volatiles from leaves than germination. 6. Volatiles from sicklepod leaves reduced germination and radicle length of sicklepod itself. 7. Collectively, it is concluded that there are water-soluble and volatile substances responsible for allelopathy in sicklepod.

A solid-state culture based on grain materials was attempted to produce a fibrinolytic enzyme for blood circulation improvement using Bacillus subtilis BK-17. The spore, rather than vegetative cell inoculation, of B. subtilis BK-17 on the solid-state culture was effective in the production of a fibrinolytic enzyme. Maximum spore production was obtained with a SFM medium (0.8% nutrient broth, 0.05% yeast extract, $10^{-1}$ M $MgCl_2$, $10^{-3}$ M $FeCl_3$, $10^{-4}$ $MnCl_2$, $10^{-5}$ M dipicolic acid, pH 6.5). Optimal pH and temperature were pH 6 and $30^{\circ}C$, respectively. The spore production reached a maximum at 60 hours of incubation. Bacillus subtilis BK-17 on the mung bean solid-state culture produced greater fibrinolytic activity, and less activity was seen in other grains such as kidney bean, soybean and corn. Protein and lipid contents of fermented soybeans were about 10 - 30% more than those of unfermented soybeans. Amino acid content was also 5 - 20% more than that of unfermented soybeans. These results indicated that fermented solid-state culture medium, fermented soybean in this case, can be utilized as a food supplement.
