Purpose: The effects of water extract and distillate from the mixture of black goat meat and medicinal herb on MG-63 osteoblast proliferation and mouse bone marrow derived osteoclast formation were investigated. Methods: Proximate composition, volatile basic nitrogen (VBN), mineral content, free amino acid composition and free fatty acid composition in black goat meat were determined. Water extract and distillate were prepared with three groups; goat meat only (BG-E, BG-D), six herbs added group (BG-E6, BG-D6), and eight herbs added group (BG-E8, BG-D8). Osteoblast proliferation, mineralization and calcium uptake activity of MG-63 cells were measured and tartrate resistant acid phosphatase activity of osteoclasts was analyzed. Results: Black goat meat had remarkably low fat and high level of calcium. Glutamic acid was the most abundant amino acid. Herbs added extract groups (BG-E6 and BG-E8) showed increased MG-63 cell proliferation in a concentration dependent manner, while all the distillates did not show the effect. All extracts and distillates showed significantly increased osteoblast mineralization depending on the concentration. In particular, herb added extract, BG-E6, increased 170.3% of control and the distillate of BG-D and BG-D6 increased up to 168.5% and 159.8%, respectively. Calcium uptake activities of all water extracts showed remarkable increase of BG-E6 and BG-E8 up to 615.5% and 628.1% of control, respectively. Ditillates had no effect except BG-D6. All water extracts significantly reduced the activity of tartrate-resistant acid phosphatase (TRAP) in osteoclasts derived from mouse bone marrow. Conclusion: Combination of black goat meat and medicinal herb increased the MG-63 cell proliferation and effectively inhibited osteoclast differentiation in both water extracts and distillate of them, which implies that they could be used as potent functional food materials for bone health.

The antimicrobial and antioxidative effect of mechanical bamboo smoke distillate (MBSD) and traditional bamboo smoke distillate (TBSD) were investigated. Antimicrobial activity was demonstrated against all the microorganisms used in this experiment and was the higher in TBSD than in MBSD, with an activity concentration in the range 10-50 ${\mu}m/8$ mm paper disc. At the same concentration the antimicrobial activities of TBSD and MBSD was Gram positive bacteria>gram negative bacteria>Lactotobacillus>yeast. The minimum inhibition concentration (MIC) of BSC was 1.0-7.3${\mu}L/mL$, and the maximum lethal concentration (MLC) was 26.7-116.7 ${\mu}L/mL$. The soybean oil oxidative stability increased with increasing BSD concentration. The induction periods of oil oxidation were 3.75, 4.57 and 12.06 days for the samples with BSD added at 0.1%, 0.5%, and 1.0%, respectively. The RAE in soybean oil with 0.5% BSD was evaluated to be 168.45%, being similar to that of the sample with 0.02% BHT.

Application of steam distillation on the analysis of pesticide residue in soil, water and crops was studied using the nitrogen distillation apparatus. Most pesticides which were extracted by organic solvents could be analyzed by the steam distillation method. For instance, distillations of PCNB, ${\gamma}-BHC$, ${\alpha}-or$ ${\beta}-endosulfan$, IBP, diazinon, fenthion, fenitrothion, alachlor, butachlor, pretilachlor, metolachlor, pendimethalin, benthiocarb and molinate were possible, but not simazine, atrazine and nitrofen. The optimum volume of distillate for a sufficient extraction of pesticide varied according to kind of pesticide. In general, the volume needed was little for carbamate, but much more for organochlorine. When the definite amount of distillate was obtained and then the condenser was washed by acetone, the optimum volume of distillate was less. Using the steam distillation method, the amount of organic solvent needed for one extraction of pesticide from soil, water and vegetable was less than the conventional solvent extraction method, and the analytical procedure became simpler. The process of concentration and clean up was mostly unnecessary, although a ghost peak was apparent in the gas chromatogram according to the kind of materials distilled.

This study was carried out to investigate on the catalytic pyrolysis products of hardwood (Alnus hirsuta (Spach) Rupr. Quercus acutissima Carruters, Robinia pseudoacacia L., and Populus tomentaglandulosa T. Lee) and comparing the rate of catalytic pyrolysis from untreated wood (ordinary wood) with that of treated wood with catalizer (Ammonium phosphate, Ammonium sulfate, Ammonium chloride and Urea). The results were summerized as follows; 1) It is the Populus tomentiglandulosa T. Lee that the species has the most content of holocellulose and pentosan. And Populus tomentiglandulosa exhibited high yield of the distillate in pyrolysis products by Ammonium phosphate with catalizer. 2) The distillate of pyrolysis products is decreased in accordance with increasing catalytic concentration. And untreated wood (ordinary wood) with catalizer has the most distillate of pyrolysis products. 3) The yield of charcoal in pyrolysis products is increased in accordance with increasing catalytic concentration and lignin content of species. 4) The caloric values of charcoal in pyrolysis products is decreased with increasing catalytic concentration. And untreated wood (ordinary wood) with catalizer had the most caloric values, but the caloric values of charcoal did not show statistically significent difference at 5% levels in catalizer.

1. Objectives The purpose of this study is to investigate the effects of oral administration of distilled Suhwagije-tang in aging rats. 2. Methods The SD rats used in this experiment were 6, 48 and 68 weeks old. These groups were treated with distilled water(DW), 1% Vitamin C(Vit. C) and 50% Suhwagije-tang(SGT) distillate respectively, once a day for 4 weeks. Blood samples were taken from heart and the levels of various parameters in serum were analysed. 3. Results and Conclusions (1) At all concentration of SGT, survival rates of liver cells were higher than the control group. (2) The rate of which the 10W-SGT group gained weight was significantly higher than that of the control groups. (3) The levels of albumin in serum of 10W-SGT group were significantly increased in comparison to those of the DW group. The levels of ALP, total cholesterol and HDL-cholesterol in serum of 52W-SGT group were significantly decreased in comparison to those of the DW group. (4) The levels of testosterone in serum of SGT groups showed no significantly changes in comparison to those of the control groups. Testosterone levels were naturally decreased with advancing years, so 72W-DW group's testosterone level was significantly decreased in comparison to those of 10W-DW group's. In contrast, 72W-SGT group's level was the highest in comparison to those of the control groups and those of deviation from 10W, 52W and 72W in SGT groups was also smaller than control groups'. (5) The levels of glucose, total-bilirubin, ALT, AST, BUN, CRP, hs-CRP, homocystein, Na, K, Na/K ratio, Cl and Ca in serum of SGT groups showed no significantly changes in comparison to those of the control groups. These results suggest that oral administration of Suhwagije-tang distillate should be effective in promoting growth and preventing rapid decline of testosterone in aging rats does not cause any imbalance in liver, kidney and electrolyte.

Volatile flavor components of fresh ginseng (Panax ginseng C.A. Meyer.) were studied. Steam distillate of fresh ginseng was extracted with ethyl ether and the extract was separated into four fraction: neutral, phenolic, acidic and basis fractions. The ethyl ether concentrates and neutral fraction were analyzed by a combination of SE-54 fused silica capillary gas chromatography and mass spectrometry. Major flavor components of fresh ginseng were predominantly mono(n +2) and sesquiterpenes(n +3) in over two hundred constituents. Of these, 28 were newly identified in volatile flavor components of fresh ginseng by GC-MS.

The purification of indole from 54.3wt% indole fraction (temperature range of distillate: $250{\sim}255^{\circ}C$) recovered by extraction-distillation combination of coal tar fraction (temperature range of distillate: $240{\sim}265^{\circ}C$) was examined by solute crystallization. The feed consists of eight components such as quinoline, iso-quinoline, indole, quinaldine, 1-methylnaphthalene, 2-methylnaphthalene, biphenyl and phenyl ether. Hexane and an aqueous solution of methanol (50 : 50 vol%) were used as the crystallization solvent and the coolant, respectively. A batch stirred tank of glass material was used as a crystallization apparatus. By increasing the operation temperature and the volume ratio of solvent to feed at initial, the purity of indole increas ed, but yields of indole showed a decreasing tendency. Solute crystallization method using hexane as a solvent was excellent because the purity of 99.3 wt% indole was recovered at the yield of 50% without washing operation.

A seawater distiller, in which the waste heat from a portable electric generator was used, with a multiple-effect diffusion still was designed. The waste gas from small generators commonly used in islands has not yet been used because it has less thermal energy; however, this waste gas can be used as a heat source for small-capacity distillers and as an additional heat source for solar stills. The proposed distiller comprises a series of closely spaced parallel partitions that are placed in contact with saline-soaked wicks. In the distiller, evaporation and condensation processes are repeated to recycle the thermal energy for increasing the distillate productivity. Experimental results show that the proposed distiller with only one-effect still can produce at least 6.7 kg/day of distilled water; the proposed distiller with a ten-effect still is expected to produce 43 kg/day of distilled water. This amount of distillate is approximately four times the maximum daily productivity of the solar stills, as determined in outdoor experiments.

In this work, the reaction characteristics for the non-catalytic esterification of palm fatty acid distillate were analyzed. The esterification reaction was assumed as the pseudo homogeneous $2^{nd}$ order reversible reaction and 'reaction effectiveness factor (${\eta}$)' was used to take accounts into evaporation and reaction of water and methanol, which take place simultaneously in the liquid phase. The nonlinear programming was used to derive appropriate kinetic parameters, the reaction rate constant and mass transfer coefficient, minimizing the error between experimental data and the numerical values. Based on these parameters, the apparent activation energy was calculated to be 43.98 kJ/mol.
