$\alpha$, $\beta$-4.8.13-Duvatriene-1, 3-diols was identified as the major component of diterponoid extracted from Nicotiana Tabacum L. The isolated duvatriendiol was thermolyged at 300'c under a stream of nitrogen. The approximately 20 compounds were separated from the thermolyzates and the 9 compounds of them were identified with GC/MS. However, the thermolyzates identified in this study differed in distribution from the products under the condition of a different temperature or photooxidation.

이문수,이운철,Rhee, Moon-Soo,Lee, Un-Chul 한국연초학회 1982 한국연초학회지 Vol.4 No.2

During the process of curing of the tobacco (Nicotiana tabacum L. ) leaves the concentration change of Nonvolatile organic acids and Higher fatty acids of the flue-cured tobacco leaves was observed. The contents of Nonvolatile organic acids in flue-cured tobacco leaves were as follows, malic> oxalic>malonic>citric>succinic acid. Higher fatty acids was linolenic>Palmitic>oleic >stearic$\geqq$linoleic acid, Citric acid content of last curing time was increased about 4~5 times in compare to before curing tobacco. It was concluded that significant changes of three variety flue-cured tobacco but a significant difference was observed in the composition of Daegu gold variety.

With the increase of the use of antibiotics and invasive procedures, infections caused by multidrug-resistant Acinetobacter baumannii(MRAB) are increasing. We screened the antibiotic producing strain B-51 for antibacterial activity against MRAB from the soils and studied the effects of culture medium on the antibiotic production of B-51. The medium conditions for maximum antibiotic productivity of B-51 was 2% glycerol, 0.5% soybean meal, 0.01% CaCl2, 0.01% MgSO4,7H2O and 0.01% KH2PO4 at an initial pH of 6.0, at 30℃ for 76 h.

This study was conducted to determine the aroma and volatile component changes from a different stalk positions of Korean flue-cured tobacco. Eight different stalk positions of flue-cured leaf tobaccos harvested in 2001 were used for this study. Thermal extraction method at two different treatment temperature($50\;amp;\;80^{\circ}C$) was applied for this experiment. Forty eight kinds of aroma and volatile components such as 2,4-heptadienal, hexadecane, 1-methyl-1H- pyridine, 2,5-dimethyl-1H-pyrrole were analyzed by using thermal extraction method. All of aroma and volatile components of leaf tobaccos were changed from a different stalk positions and treatment temperature. Leaf tobaccos in middle stalk position have a higher concentration of aroma and volatile components such as norsolanidione, 4-pyridinecarboxaldehyde, 4-methyl-4-OH-2-pentanone, acetic acid, propylene glycol, 1-methyl-2-pyrrolidinone, 2,5-dimethyl-1H-pyrrole. Also, Megastigmatrienone 1, 3-oxo-[alpha]­ionol, 6,10,14-trimethyl-2-pentadecanone, heptadecane, 6-methyl-2-isohexyl-l-heptene concentration were low in the middle stalk position and high in both bottom and upper position. Treatment temperature affected on the changes of many aroma and volatile components in leaf tobacco. Most of aroma and volatile components such as, 2,4-Heptadienal, dodecanoic methylester, famesol isomer and 3-acetylpyridine were sharply increased as increasing treatment temperature. This results can be used to estimate the aroma characteristics of cigarette blend using a different stalk position of leaf tobacco.

This study was conducted to evaluate the ability of anion generating air cleaner to remove gases, vapor and particles from closed room contaminated with environmental tobacco smoke (ETS). The measurements covered particle sizes of 13.8-542.5nm, particle concentration, surface area, volumes UVPM, FPM, solanesol, and the following gases and vapor; carbon dioxide, carbon monoxide, nicotine, and 3-ethenylpyridine. Tobacco smoke was generated and mixed in a closed room in which the airflow rates were in the range of 0.00-0.04 m/s. The anion generating air cleaner was startedl and the decay rates for the gases, vapor and particles were measured, When the use of anion generating air cleaner, solid components of ETS, such as respirable suspended particle (RSP), utraviolet particulate matter (UVPM, fluorescent particulate matter (FPM) and solanesol was sharply decreased, and vapor phase components of ETS, such as nicotines 3-ethenylpyidine were modelately decreased by time elapse. Even the use of anion generation air cleaner, the decreasing rate of carbon dioxide concentration was similar with control, and the decreasing rate of carbon monoxide was slower than that of control. Our results indicated that the use of anion generting air cleaner had an effect on reduction of solid and vapor components from ETs, but it had no effect on gaseous components of ETS.

Aloe is an attractive potential food source because it has functional uses. It has been widely used as a well-being food and drink. The antioxidant activity was estimated by measuring DPPH free radical scavenging activity. We investigated the quality characteristics of cookies prepared by adding various concentrations of aloe powder (0%, 1%, 3%, 5%, all w/w) as a substitute for flour. In this study, the DPPH free radical scavenging activity, moisture content, and hardness of cookies significantly increased with increasing aloe powder, while the pH, spread factor and L and b values slightly decreased. Sensory evaluation scores in terms of texture were shown to be very similar statistically, but color, flavor, taste, and overall acceptability scores were lower than the control. As a result of this study, the quality of cookies with the addition of 1% aloe powder were the most suitable in terms of taste, flavor, texture, and sensory properties.

In order to produce Hongkuk-ju, the production and characterization of Hongkuk (Monascus red koji) by Monascus anka KCTC 6121 were investigated. The optimum cultural conditions for the production of enzyme (${\alpha}$-amylase and glucoamylase) and pigment (yellow and red) from this strain on solid culture (steamed rice) were examined. The results showed that the production of ${\alpha}$-amylase and glucoamylase reached the highest for 9 days and 8 days, respectively. Since then, the productions decreased slightly. The production of yellow and red pigments reached the highest for 8 days, decreasing slightly soon after. The optimal content of the initial moisture equally presented 30% in the enzyme and pigment production. After that, the enzyme production decreased slowly, whereas pigment production decreased sharply. The optimal temperature of the culture also showed $30^{\circ}C$ in the production of enzyme and pigment. It was found that the initial inoculum size in enzyme and pigment production was 10% and 20%, respectively. Under these optimal conditions, the production of monacolin K and citrinin was 74.35 mg/kg and 5 mg/kg for 12 days, respectively.

To use the filter materials for selective removal of carbonyl compounds in cigarette mainstream smoke, hydrazine such as 2,4-dinitrophenylhydrazine and dansylhydraznie impregnated adsorbents were prepared with perchloric acid or phosphoric acid as a accelerator in hydrazone formation reaction. The change of morphology of adsorbents in various of impregnator were investigated by SEM. Impregnation amount caused by reaction time, acid type and impregnation reagent, and the adsorption properties of carbonyl compounds in cigarette mainstream smoke were investigated. Amounts of impregnation was increased as increasing reaction time. The removal amount for vapor phase carbonyl compounds by 2,4-DNPH impregnated adsorbent was higher than that of dansylhydrazine impregnated adsorbent. The selectivity of 2,4-DNPH impregnated polyacrylic type adsorbent was superior to those of other adsorbents. This results indicated that the 2,4-DNPH impregnated polyacrylic adsorbent was applicable to cigarette filter material because of its fast reactivity and porosity.

This study was conducted to investigate the delivery pattern of volatile organic compounds(VOCs) in mainstream smoke generated by the combustion of a different ventilated cigarette. To compare the delivery pattern and the concentration of VOCs in mainstream smoke, the six different ventilated cigarette was manufactured and analyzed VOCs using the GC/MS. As a result of this experiments, cambridge filter used to trap the particulate matter in mainstream smoke did not affect on the trapping of VOCs components, and two impinger method among the trapping methods was the best condition to trap VOCs from mainstream smoke. As the slope of the delivery of VOCs such as isoprene, acrylonitrile and toluene were higher than 1, but that of benzene was lower than other VOCs.
