The possibility of identification of families of antibacterial agent residues in fish tissue was studied by disk assay using three test organisms, Bacillus subtilis BGA, Micrococcus luteus ATCC 9341, and Bacillus cereus var. mycoides ATCC 11778. In the present method, a simple clean-up procedure was performed to obtain the aqueous solution from homogenized flounder muscle sample(10g) in Mcilvaine buffer. Then, aqueous solution was fractionated into A and B to be used in disk assay by choloroform and Sep-Pak $C_{18}$ cartridge column after being defatted in hexane. The chloroform layer of fraction A was used for the analysis of macrolide antibiotics(ML), sulfa drugs(SA), chloramphenicol(CP), and quinolone antibiotics(QN). Adsorbed materials to Sep-Pak $C_{18}$ of fraction B were also employed for the analysis of penicillins(PC), tetracyclines(TC), and nitrofuran derivatives(NF) Minimun-detectable concentrations by the present method were, $0.1{\mu}g$/g for oxytetracycline, tetracycline, doxycycline, spiramycin and ciprofloxacin, $0.025{\mu}g$/g for erythromycin and ampicillin, $1.0{\mu}g$/g for sodium nifurstyrenate and florfenical, $0.25{\mu}g$/g for sulfamonomethoxie and sulfadimethoxine, $2.5{\mu}g$/g for oxolinic acid and flumequine, and $15{\mu}g$/g for piromidic acid, respectively. Three test organisms showed different sensitivity patterns for each family of antibacterial agent. Sensitivity patterns were B. cereus > B. subtilis > M. luteus for TC and NF, M. luteus > B, subtilis > B. cereus for ML and PC, B. cereus = B. subtilis > M. luteus for CP and QN, and B. subtilis > B. cereus=M. luteus for SA. The present method utilizing these characteristics could be useful as a routine screening test for the determination of family of antibacterial agent residues in fish tissue.
Residue level of myclobutanil[2-p-chlorophenyl-2-(1H-1,2,4-trizol-l-yl-methyl) hexane nitril] and number of soil microorganism were investigated at different environmental conditions such as the sterile and the non-sterile soils, moisture content, pH, temperature, application rate, and soil types under laboratory and field to study the effect of those factors on degradation characteristics of this fungicide and change of microflora in soil. Decomposition rate of myclobutanil was 3.9 times faster in the non-sterile soil than in the sterile soil, 1.6 times in the field than in the laboratory, 1.4 times in the concentration of 10ppm than in that of 20ppm, and 1.2 times in the clay loam soil than in the silty loam soil. Degradation rate of myclobutanil was the fastest at pH 9.0 among the tested pHs and the latest at pH 5.5. Degradation rate of myclobutanil was in order of $27^{\circ}C$ > $37^{\circ}C$ > $17^{\circ}C$. Otherwise, the effect of soil water content on myclobutanil degradation was found not clear. Number of microorganism in the non-sterile soil was remarkedly more than that in the sterile soil. Numbers of microbes were not significantly different between treatment plot and non-treatment plot of myclobutanil at the different conditions of soil moisture content, pH, temperature and soil type. Numbers of fungi and total microbes were more in the treatment than in the non-treatment of myclobutanil at field test but the same trends were not found at laboratory test. Within non-treatment of myclobutanil, numbers of microbes were not significantly different under the various condition of pH, application rate, and soil type in laboratory and upland field. The number of bacteria were more in 60% moisture content of water holding capacity than in 40% and the number of fungi were more in $17^{\circ}C$ of soil temperature than in $37^{\circ}C$. Within the application plot of myclobutanil, numbers of microbes were not significantly different at various pH in laboratory and upland field. The number of bacteria and total microbes were more in 80% moisture content of water holding capacity than in 40% and 60% and actinomycetes were more at $27^{\circ}C$ in the clay loam soil than at $17^{\circ}C$ in the silty loam soil.
The study was performed for elucidating angiotensin converting enzyme (ACE) inhibitory activity and comparing antioxidative activity of Panax ginseng extracts prepared at different conditions. Total phenolic content, inhibitory activity on ACE and antioxidative effects were tested on 10 ethanolic extracts and correlation coefficient between total phenolic content and physiological activity was calculated. Yield and total phenolic content of 50% ethanolic extract prepared at $85^{\circ}C$ exhibited the highest value as 42.52% and 0.82%, respectively. Among the fractions obtained from 50% ethanolic extract prepared at room temperature, water fraction showed the highest value in yield as 72.08% and ethyl acetate fraction did in total phenolic content as 6.59%. In the test on ACE inhibitory activity, 50% ethanolic extract obtained at room temperature indicated the strongest effect of 93.8% which was higher than 85.2% of commercialized ACE inhibitor and solvent fractions showed potent inhibitory activity in order of hexane fraction, diethyl ether fraction, ethyl acetate fraction, butanol fraction and water fraction at concentration of $4000{\mu}g/ml$. 50% Ethanolic extract prepared at $85^{\circ}C$ had the most potent inhibition effect on human LDL oxidation as 78.2% at $200{\mu}g/ml$ and the other extracts also did above 60%. Diethyl ether fraction and ethyl acetate fraction showed strong inhibition activity $(34.38%{\sim}78.13%)$ on LDL oxidation at concentration of $10{\sim}200\;{\mu}g/ml$. From the statistical analysis via SAS program, correlation coefficient between total phenolic content and ACE inhibitory effect was 0.6353 at P<0.05. Conclusively, this report showed that the most efficient extraction condition for elevating inhibitory activity on ACE and LDL oxidation, phenolic content and yield from Panax ginseng was 50% ethanol extraction at room temperature or high temperature condition. And Panax ginseng would be used for preventing hypertension or atheroscrelosis for man via inhibitory action on ACE and LDL oxidation.
Defatted rice bran is mixed with diluted acid solution, the mixture is agitated some hrs. at constant temparature. After the mixture is filtered, thus filtrate is obtained.

This study was conducted to investigate the synthesis of previtamin D$_3$(PreD$_3$), lumisterol$_3$($L_3$) and vitamin $D_3$ ($D_3$) in dorsal skin of 8 week-old broiler chicks irradiated by UV light. The Hubbard line day-old broiler chicks were fed with vitamin D-depleted ration (or 3 weeks and with medium broiler diet for 5 weeks. The 3$\times$3cm area of dorsal skin was defeathered one day before the experiment. The 310nm UV light was utilized to irradiate the dorsal skin, which was separated into epidermis and dermis after irradiation. The irradiated epidermis was extracted with 60% ethyl acetate in n-hexane and PreD$_3$, $L_3$, D$_3$ and 7-dehydrocholesterol (7-DHC) were analyzed by HPLC. When UV light was treated for 0, 90 or 150min. the L$_3$ content in the separated epidermis was 219, 298 or 248ng/$\textrm{cm}^2$, respectively. The irradiation for 90min produced 79ng/$\textrm{cm}^2$ of L$_3$, and the synthesizing rate was 0.9ng/$\textrm{cm}^2$/min. The PreD$_3$ content was 23, 33 or 12ng/$\textrm{cm}^2$ when exposed for 0, 60 or 150min The 10ng/$\textrm{cm}^2$ of PreD$_3$ was produced for 60min. The D$_3$ was generated by 27ng/$\textrm{cm}^2$ when exposed for 90min. The 7-DHC contents were decreased gradually from initial 123 to 35ng/$\textrm{cm}^2$ when exposed for 150 min, showing the rate of disappearance as 0.6ng/$\textrm{cm}^2$/min.
This study was conducted to increase sweetpotato utilization and to determine the vegetative value of sweetpotato tips by investigating the phenolic compounds, antioxidative effect in oil, electron donating ability, nitrite scavenging effect and ACE inhibition activities. The phenolic compounds present in sweetpotato tips are the gallic, chlorogenic, gentisic, caffeic, couramic and ferulic acid, which are 16-122 times higher compared to other vegetables such as spinach, soybean sprout, and perilla leaves. In each solvent extract, the total phenolic compounds (175.8mg/g) was composed of 55% EtOAc extraction and 39% BuOH extract, respectively. The results of induction period using the Rancimat method showed that the antioxidant activity of SP tips was higher than the tocopherol or BHT. The relative levels of each solvent extract in SP tips were as follows: EtOAc>BHT>BuOH>Tocopherol>Water>$CHCl_3$>Hexane. The peroxide value was measured every 5 days for 25 days during storage and results showed that the peroxide value, the tips, tuberous root and tocopherol were lower compared to spinach, soybean sprout and perilla leaves. Nitrite scavenging effects were excellent in sweetpotato tips, perilla leaves and soybean sprout, especially, inhibition rate of perilla leaves (72%) were superior to the others. In process of solvent extraction, activity of BuOH and water extractions were the best. ACE inhibition activity in sweetpotato tips was 1.5 times higher than in tuberous roots and $1.9{\sim}3.7$ times higher than in spinach, soybean sprout, perilla leaves.
This study was designed to develop a functional pharma-food using Salicornia europaea (SE). Tiny seeds from the mature SE were collected, and their biological activities were evaluated. The extraction yield of the seed in hot water was found to be 29.6% and the hot water extract (HWE) contained 25.7 mg/g total polyphenol (TP) and 11.5 mg/g total flavonoid (TF), which are similar to those contained in leaf and stem of SE. Among the subsequent organic solvent fractions, the ethylacetate (EA) fraction exhibited the highest content of TP (158.3 mg/g), TF (136.2 mg/g), and total sugar (228.3 mg/g). The EA fraction exhibited broad-range antibacterial activities against gram-positive bacteria, and the butanol fraction exhibited growth inhibitory effect against only Staphylococcus epidermidis. An antioxidation activity assay of the HWE and its fractions showed the EA fraction to have the highest radical scavenging activity with $RC_{50}$ values of 57.0, 29.0, and $28.9{\mu}g/ml$ against DPPH anion, ABTS cation, and nitrite, respectively. The $RC_{50}$ values of vitamin C against DPPH anion, ABTS cation, and nitrite were 10.7, 4.0, and $18.0{\mu}g/ml$, respectively, indicating that the EA fraction of SE has potent antioxidant compounds. In an anticoagulation assay, the EA fraction exhibited a 15-fold extended thrombin time at 5 mg/ml and activated partial thromboplastin time at 7 mg/ml, which are comparable to the activities of aspirin. The HWE and its fractions had no hemolysis activities against human RBCs at up to 1 mg/ml. These results suggest that the EA fraction from SE has a great potential as a new antibacterial and anticoagulation agent.

This study was aimed to evaluate and compare the proximate composition, antioxidant and antiproliferative activities of Sageretia thea (Osbeck) M.C.Johnst (S. thea) fruit and blueberry. The calorific value, crude protein, crude fat, crude ash, and carbohydrate were higher in S. thea fruit than in blueberry. S. thea fruit and blueberry have different profile of free sugars, in which amounts of fructose, glucose, and maltose were much higher in S. thea fruit than in blueberry. The methanol extracts of S. thea fruit contain higher amounts of total polyphenol and anthocyanin compared to those of blueberry extracts. In additions, 2,2-diphenyl-1-picrylhydrazyl (DPPH), alkyl, and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging activities are greater in S. thea fruit extracts. Ethyl acetate fractions and n-butanol fractions of S. thea fruit and blueberry show the most potent scavenging activity in DPPH-, alkyl-, and ABTS-radical scavenging assay. The ethyl acetate fractions of S. thea fruit and blueberry are the richest fraction in polyphenol contents while the n-butanol fractions of those are the highest fraction in anthocyanin contents. Furthermore, both S. thea fruit and blueberry extracts protect human dermal fibroblast cells against a $H_2O_2$-induced oxidative stress. The antiproliferative activities of n-hexane and chloroform fraction from S. thea fruit and blueberry were observed in AGS human gastric cancer and MDA-MB-231 human breast cancer cells. Therefore, our results suggest for the first time that the antioxidant and antiproliferative activities of S. thea fruit is comparable to that of blueberry and the nutritional value of the former is even superior to that of the latter.
This study was conducted to determine the optimum condition of extraction and antioxidant activity of ethanol extracts of Epimedium koreanum Nakai based on the icariin quantity. Also, further organic solvent fractions of hexane, chloroform, ethyl acetate and butanol were obtained from the ethanol extract of Epimedium koreanum Nakai at different temperatures. Total ethanol extraction yield of wild grape seed ranged from 11.8% to 39.3% depending on the concentration of icariin as well as different ethanol concentration, extraction temperature and time condition. Among different extraction temperatures and time, the highest extraction yield of 39.3% was obtained at 70% ethanol for 3 hour at $50^{\circ}C$ in the sample containing the 0.596% icariin (KE9412). In the meantime, the strongest free radical scavenging effect $(RC_{50})$ with $18.9{\mu}g/mL$ in the KE9412 sample was observed in 70% ethanol extract of Epimedium koreanum Nakai extracted for 7 hour at $70^{\circ}C$, while $RC_{50}$ with $35.2{\mu}g/mL$ was observed in the KE9405 (0.20% icariin content) sample at same condition. Also, antioxidant activity of ethanol extracts of Epimedium koreanum Nakai increased as icariin concentration increased. Among each fraction obtained from organic solvents, butanol fraction was found to have the strongest $RC_{50}\;(39.2{\mu}g/mL)$ and followed by ethylacetate $(49.0{\mu}g/mL)$, water $(118.8{\mu}g/mL)$, ethylacetate $(119.8{\mu}g/mL)$, and chloroform fraction $(138.5{\mu}g/mL)$ respectively.
One strain of Penicillium sp. (175-66-B), isolated from soil, was able to produce a substance that has a strong inibition activity against the Agkistrodon and Trimeresurus venoms. In this experiment, the chemical and biological properties of the sample were investigated. As an inhibitory substance, it was effective to the proteinase, hemorrhagic and lethal factors of Agkistrodon and Trimeresurus venoms, and also effective to several fractions of the proteinases and hemorrhagic factors of Agkistrodon halys blomhoffi venom. Moreover, in the addition of prednisotone, it was more effective for the cure of the mouse envenomated with the venom amount of two fold of MLD$_{100}$. This substance was very stable to the acid, alkali and heat. Its melting point was high enough to sublime at 222$^{\circ}C$ without any decomposition. This sample was easily dissolved only in hot water, but not in several organic solvents except for a little dissolution in elate. It did not have the chelating activity. It had very strong specificity to the snake venoms. but its activity was depressed by the addition of zinc or cupric salts. This sample had no acute toxicity to the mouse. Its chemical formula was $C_{16}$$H_{12}$$N_2$$O_{10}$ with the molecular weight of about 392. It has two epoxy groups and four carboxyl radicals, but amino, nitrite and nitrate radicals, unsaturated bonds and aromatic ring were not detected. Theuchemical configuration of this sample was suggested to be;
