  • Ethanol extracts from 36 vegetable samples were assayed for their growth-promoting effects on Bifidobacterium bifidum, B. longum, and Lactobacillus casei The growth-promoting effects varied according to bacterial strain and vegetable species. In modified Gy rgy broth, extracts of Lactuca sativa, Lycopersicon esculentum and L escutentum var. cerasiforme exhibited strong growth-promoting responses toward B. longum, and significant and strong growth- promoting response toward B. bifidum was observed in extracts of Actinidia arguta, Allium cepa, A. sativum, Brassica campestris subsp. napus vats. pekinensis, Capsicum frutescens, Daucus carota var. sativa, L sativa, 1. esculentum and L. esculentum var. cerasforme, Nelumbo nucifera, Cucurbita moschata, Lackca sativa var. capitata, and Rubus coreanus. For L casei, extracts of A. fshlosum, A. hberosum, Cichorium intbus, Cucurbita moschat\ulcorner Ipomoea batatas, 1. sativa var. capitata, L. esculentum, P. brachycarpa, Raphanus sativus, R. coreanus, and S. melongena strongly enhanced the growth of this bacteria. In modified Gy rgy broth, the promoting effect was most pronounced with B. bifidum and L. casei among lactic acid bacteria used. In MRS broth, A. arguta, A. cepa, A. sativum, B. campestris subsp. napus var. pekinensis, C. frutescens, and D. carota var. sativa L. satiw var. capitata, and R. coreanus strongly enhanced the growth of B. bifidum, Growth of B. longum was strongly affected by the addition of extracts from L. sativa var. capitata. For L casei, moderate growth-promoting responses were observed in 9 vegetable extracts. The promoting effect in MRS broth was most pronounced with B. bifidum among lactic acid bacteria used.

  • The study was carried out to establish an efficient protocol for shoot organogenesis and plant regeneration from stem explant cultures of Lycopersicon esculentum cv. Micro-Tom. The regenerated shoots obtained from stem explant cultures on solid MS medium containing the different concentrations of BAP. The highest number of shoots (5.3) per explant and shoot growth (0.7 cm) was obtained on MS medium containing 4.0 mg/L BA. The additions of AgNO$_3$ and putrescine substantially improved the shoot regeneration frequency, at the optimal concentration of 7 mg/L and 50 mg/L respectively. The regenerated shoots (about 1 cm) were normal and could be easily rooted with 0.1 mg/L IBA treatment. The rooted plants were hardened and transferred to vermiculite with a 92% survival rate where they grew normally.

  • The inhibitory effect of the aerial parts of Fagopyrum esculentum on the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical was examined. The n-butanol fraction from the methanol extract of title plant showed stronger inhibitory effect than other fractions on DPPH radical. Two flavonoids were isolated from n-butanol fraction having the potent activity and elucidated as quercetin-3-O-${\alpha}$-L-rhamnoside and quercetin-3-O-rutinoside on the basis of spectral evidence. The $IC_{50}$ values of these compounds on DPPH radical were 6.56 ${\mu}M$ and 8.37 ${\mu}M$, respectively.

  • In Peucedanum japonicum and Aster tataricus L. chlorogenic acid was identified by methods of P.P.C. and T.L.C. $L-Phenylalanine-U-^{14}C\;and\;sodium\;acetate-2-^{14}C$ were administered to Peucedanum japonicum, $L-Tyrosine-U-^{14}C$ to Aster tataricus and $caffeic\;acid-carboxyl-^{14}C\;and\;L-tyrosine-U-^{14}C$ to Fagopyrum esculentum $M_{OENCH}$. The incorporation of each compound into chlorogenic acid was compared. $L-Phenylalanine-U-^{14}C$ showed higher incorporation to chlorogenic acid than sodium $acetate-2-^{14}C$ in Peucedanum japonicum. $Caffeic{\;}acid-carboxyl-^{14}C$ was higher to chlorogenic acid than $L-tyrosine-U-^{14}C$ in Fagopyrum esculentum. $L-Tyrosine-U-^{14}C$ was comparatively low in Aster tataricus.

  • In this study, we investigated the potential of Lactobacillus brevis AR1 fermented broth containing various grains (Fagopyrum esculentum, Scotch oat, Sesamum indicum, Glycine max Merr, Castanea crenata, Oryza sativa L., Hordeum vulgare L., Perilla frutescens var. japonica Hara, or Triticum aestivum L.) or Saccharina japonica as a source of collagen synthesis in cosmetic products. The treatment of Lb. brevis AR1 fermented broths containing F. esculentum or S. japonica water extracts was markedly increased the synthesis of collagen in fibroblasts. The collagen synthesis capacity of the S. japonica fermentation product was higher than that of β-glucan, which was used as a positive control. Under controlled conditions in broths containing F. esculentum or the S. japonica extracts with 4% monosodium glutamate (MSG), Lb. brevis AR1 produced γ-aminobutyric acid (GABA) at a concentration of 180 mM, with an 84.5% GABA conversion rate after 72 h. Both the F. esculentum and S. japonica fermentation broths produced by Lb. brevis AR1 reduced inflammatory responses on mouse skin and did not show cell cytotoxicity in fibroblasts. These results suggest that both the F. esculentum and S. japonica fermentation products of Lb. brevis AR1 could be used as functional materials in cosmetic products to combat wrinkles and skin inflammation.

  • The liquids of Lycopersicon esculentum were extracted with 70% aqueous MeOH and the concentrates were partitioned into EtOAc, n-BuOH, and H2O fractions. The repeated silica gel and octadecyl silica gel column chromatographies for the EtOAc fraction, whose activity was confirmed, led to isolation of one flavonol compound. The chemical structures of the compound were determined as quercetin (1) based on spectroscopic analyses including nuclear magnetic resornance, infrarad spectroscopy, and mass spectroscopy. Through this study, the antioxidant efficacy was confirmed by demonstrating that the L. esculentum fraction showing an increase in glutathione mean (GM) and a decrease in glutathione heterogeneity (GH) uniformly raises the intracellular glutathione (GSH) level.

  • Antibacterial, antifungal, and Angiotensin-I-converting enzyme (ACE) inhibitory activities of buckwheat (Fagopyrum esculentum and F. tataricum) hydrolyzed by Viscozyme L and Alcalase 2.4 L were investigated. The Alcalase 2.4L-hydrolyzed buckwheat showed highest yield of 22.10-24.65%. F. esculentum hydrolysate treated with Viscozyme L from Salmonella typhimurium (clear zone: 3-4.7 mm) and Listeria monocytogenes (clear zone: 4-7.2 mm) showed highest antimicrobial activity among enzymes used. F. esculentum hydrolysate treated with Trichoderma reesei showed strongest antifungal activity among enzymes used (clear zone: 3.7-12 mm). Alcalase 2.4L-hydrolyzed F. esculentum and F. tataricum showed strong ACE inhibitory activities (61.19% and 94.48%, respectively).
