Comparison of the volatile components in two Chinese wines, Moutai and Wuliangye
Journal of the Korean Society for Applied Biological Chemistry - - 2009
Volatile and odorous components in two Chinese wines, Moutai and Wuliangye, were partially investigated by direct solvent extraction. Sample extracts were analyzed by gas chromatography/ mass spectrometry and gas chromatography-olfactometry. Fifty-six and thirty-eight compounds were found in Moutai and Wuliangye, respectively, including esters (19, 20), alcohols (8, 7), acids (6, 3), furans (5, 2)......
The effect of caffeic acid on the antinociception and mechanisms in mouse
Journal of the Korean Society for Applied Biological Chemistry - Tập 54 - Trang 177-182 - 2011
Antinociceptive profiles of caffeic acid were examined in ICR mice. Caffeic acid administered orally (from 1 to 10 mg/kg) showed an antinociceptive effect in a dose-dependent manner as measured in the acetic acid-induced writhing test. Moreover, the cumulative response time of nociceptive behaviors induced by an intraplantar formalin injection was reduced by caffeic acid treatment during the 2nd p......
Evaluation of a Pyrethrum Emulsion Prepared in Food-acceptable Components in Controlling Green Peach Aphid (Myzus persciae)
Journal of the Korean Society for Applied Biological Chemistry - Tập 52 - Trang 176-179 - 2009
Green peach aphid, Myzus persicae, is one of major pests attacking greenhouse pepper plants in Korea. We examined a pyrethrum emulsion for the control of M. persicae. The emulsion was prepared by blending natural pyrethrum extracts with food-acceptable components. The emulsion produced a clear aqueous solution when diluted in water. Laboratory evaluation showed an average 80% mortality of 2nd-inst......
Degradation of prochloraz by rice bakanae disease pathogen fusarium fujikuroi with differing sensitivity: a Possible explanation for resistance mechanism
Journal of the Korean Society for Applied Biological Chemistry - Tập 53 - Trang 433-439 - 2010
The fungicide prochloraz was subjected to degradation by the pathogen causing rice Bakanae disease, Fusarium fujikuroi, in order to gain an insight into the mechanisms of sensitivity and resistance to the fungicide. Growth-inhibiting assays of pathogens conducted on potato dextrose agar (PDA) plates by a paper-disc agar-diffusion method. Significant growth inhibition of the sensitive strain CF106 ......
Fate, occurrence, and toxicity of veterinary antibiotics in environment

Degradation of limonene by gamma radiation for improving bioethanol production
Journal of the Korean Society for Applied Biological Chemistry - Tập 57 - Trang 1-4 - 2014
Use of orange peel as a raw material for bioethanol production requires removal of its limonene content, which inhibits fermentation. Orange peel was pretreated using electron beam or gamma ray irradiation. Limonene content decreased in a dose-dependent manner, with approximately 60% reduction compared to the control after gamma irradiation at a dose of 800 kGy. However, electron beam irradiation ......
Development of a lipase-based time temperature indicator system for monitoring ground beef quality
Journal of the Korean Society for Applied Biological Chemistry - Tập 55 - Trang 535-540 - 2012
A time-temperature indicator (TTI) based on Burkholderia cepacia lipase (BCL) activity was developed for monitoring ground beef quality under dynamic storage conditions. The growth of Pseudomonas spp., the major specific spoilage bacterium in meat, was used as a ground beef spoilage index. Arrhenius and logistic models were used to show temperature dependence of the growth of Pseudomonas spp. in g......
Flavonoid glycosides from the fruit of Rhus parviflora and inhibition of cyclin dependent kinases by hyperin
Journal of the Korean Society for Applied Biological Chemistry - Tập 55 - Trang 689-693 - 2012
Chrysoeriol-7-O-β-d-glucopyranoside (1), luteolin-7-O-β-d-glucopyranoside (2), quercetin-3-O-β-d-glucopyranoside (3), quercetin-3-O-β-d-galactopyranoside (4), and quercetin-3-O-α-l-rhamnopyranoside (5) were isolated for the first time from the fruits of Rhus parviflora. The chemical structures of the compounds were determined using nuclear magnetic resonance, fast atom bombardment mass spectrometr......
Expression and functional analysis of rice plastidic maltose transporter, OsMEX1
Journal of the Korean Society for Applied Biological Chemistry - Tập 56 - Trang 149-155 - 2013
In Arabidopsis, maltose is a major product of the transitory starch degradation pathway at night, and its mobilization from the chloroplasts to the cytosol in leaf tissues via a plastidic maltose transporter, AtMEX1, is essential for normal plant growth. However, such a starch utilization pathway has not yet been characterized in rice (Oryza sativa), a monocot model plant. Examination of expressio......
