The isolation of volatile compounds by vacuum-distillation with freeze-drying was tested 1 with fresh ginseng roots. The roots were frozen at-8$0^{\circ}C$; they were dried at-4$0^{\circ}C$ tinder vacuum(40 tory), for 24 hours; and the ice condensed at the silrface of condenser in the freeze-dryer was thauved at room temperature. The ether extract of the resulting aqueous solution was analyzed by gas chromatography (GC) equipped with a flame ionization detector (FID) or a nitrogen-phosphorils detecto(NPD) and by gas : chromatography/mass spectrometry(GC/MS). More than forty peaks were observed in the CG(FID) profile. and more than ten peaks were observed in the GC(NPD) profile. Among them, thirteen components 1including one aldehyde, four hydrocarbons, two esters, folly alcohols, and two vyrazines were identified: six components the molesuiar ions of which were m/z, 204 were estimated to be a series of azulene compounds; and the other components unidentified were estimated to have molecular weights of lower than 254. Therefore, the freeze-drying technicue is thought to be usefu1 for the isolation of volatile compounds of such low molecufilar weights from vegetables, fruits and biological fluids as well as fresh ginseng roots under the tested conditions.

Objectives : The fresh young leaves and dried fruits of Zanthoxylum piperitum (Korean name: Chopi) are used as diuretics, stomachies, anthelmintic and for the treatments of disorders of the digestive organ in Asia. We investigated inhibitory effects of Zanthoxylum piperitum extract on lipopolysaccharide(LPS)-induced production of nitric oxide(NO) and pro-inflammatory cytokines including $TNF-{\alpha}$ and $IL-1{\beta}$ from RAW264.7 mouse macrophage cells. Methods : After methanol extract of Zanthoxylum Fructus (Zanthoxylum extract) was pretreated in RAW264.7 cells, the cells were stimulated with LPS. Cell toxicity of Zanthoxylum extract was assayed bv MTT assay. The production of NO from the cells was measured in culture medium by Griess reaction. The production of $TNF-{\alpha}$ and $IL-1 \;{\beta}$ from the cells was measured in culture medium by ELISA. Results : Zanthoxylum Fructus extract greatly inhibited the production of inflammatory mediators such as NO, $TNF-{\alpha}$ and $IL-1{\beta}$ from LPS-stimulated RAW264.7 cells. Conclusion : This result suggests that Zanthoxylum extract may have an anti-inflammatory effect through the inhibition of inflammatory mediators.

Objective: Gastric cancer is an important public health problem in the world and Turkey. In addition to Helicobacter pylori (H. pylori), smoking, alcohol consumption and family history, certain dietary factors have been associated with its occurrence. The impact of dietary habits and life-style factors on the risk of gastric cancer in Turkey were evaluated in this study. Design: A questionnaire was applied to 106 patients with gastric adenocarcinoma and 106 controls without cancer matched for age (range 28-85 years) and gender selected from a hospital based population. Adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated with logistic regression analysis. Results: The incidence of H. pylori was 81.3% in patients. Frequent consumption of salty dishes, very salty foods like pickles, soup mixes, sausages, foods at hot temperature (ORs = 3.686, 7.784, 5.264, 3.148 and 3.273 respectively) and adding salt without tasting (OR = 4.198) were associated with increased gastric risk. Also heavy smoking and high amount of alcohol consumption (p = 0.000) were risk factors. Frequent consumption of green vegetables, onion, garlic and dried fruits (ORs = 0.569, 0.092, 0.795 and 0.041) was nonsignificantly associated with decreased risk. Conclusion: Improved dietary habits, reducing salt consumption and eradication of H. pylori infection may provide protection against gastric cancer in Turkey.

In this study, four plants grown naturally in Egypt that are usually consumed by pastoral nomads were screened for their total phenolic contents, antioxidative, and anti-$\alpha$-amylase activities. Dried powder of plant's part was extracted in absolute or 70% ethanol. A polar extract of Panicum turgidum (PTPE) had the highest total polyphenol content {92.5 mg gallic acid equivalents (GAE)/g}, followed by an alkaloid extract of Withania somnifera (WSAlk; 77.5 mg GAE/g), and an ethanol extract of Leptadenia pyrotechnica (LPEE; 59.1 mg GAE/g). By employing different assays such as DPPH radical scavenging, reducing power, $Fe^+$ chelating, $H_2O_2$ scavenging and total antioxidant capacity, it was shown that PTPE, WSEE (ethanol extract of W. somnifera), WSAlk and LPEE had promising antioxidant activity, though, their potency varied according to the different tests. WSAlk had the highest level of $\alpha$-amylase inhibition (40.2%) in vitro, followed by WSEE (30.5%). Therefore, it can be concluded that these plants, especially extracts of PTPE, and WSAlk are beneficial to physiological health, and could be used in food and pharmaceutical industries to prepare dietary supplements, functional foods or food preservatives.

The objective of this study was to determine the effects of different growing regions on quality characteristics, total bioactive compound contents, and in vitro antioxidant activity in aronia. Aronia grown in 3 different regions (Sangjoo, Ulju, and Youngcheon) in Korea was obtained and used fresh or as a freeze-dried powder. No statistically significant differences were observed for moisture, ash, crude lipid, and crude protein contents in aronia sampled from the 3 different regions. Aronia grown in Sangjoo had the highest total acid content and the lowest sugar content and pH value. Conversely, aronia grown in Youngcheon possessed the lowest total acid content and the highest sugar content and pH value. Aronia grown in Sangjoo possessed relatively high levels of polyphenols, flavonoids, and anthocyanins, as well as high antioxidant activity in comparison with aronia produced in other regions. Aronia grown in Youngcheon scored the highest for taste and overall acceptability in sensory evaluations, which may be related to the high sugar content and pH, and the low total acidity of the fruits. It is possible that higher sugar contents and pH, and lower total acidity in the aronia grown in Youngcheon result in more preferable sensory characteristics. However, they also contain relatively low levels of total polyphenols, flavonoids, and anthocyanins, and have low antioxidant activity as measured by 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging assays.

Effects of the root-knot nematode, Meloidogyne hapla, on the growth and yields of hot-pepper (var.: Cheongyong gochu) and tomato$(var.:\;Bogsu\;\#)$ were studied with inoculating 500, 2,500, 5,000, 7,500, 10,000 and 20,000 nematodes per plant in pots. Results were analyzed with comparing weight of fruits harvested throughout the season from both hot-pepper and tomato, and with mineral contents in dried stoots and roots of pepper plant 20 weeks after the inoculation. No significant difference was found on the plant growth at all levels of inoculation until the 8th week after the inoculation. However, the plant growth was significantly depressed from the 12th week in the pots inoculated with over 10,000 nematodes, and the yields were reduced by $16\%$ in hot-pepper and $14\%$ in tomato respectively when 10,000 nematodes were inoculated.

This study examined the quality change of red peppers during storage at various temperatures and humidities. It was observed that red peppers showed mold at aw 0.75(>25% water content), discoloration at aw 0.33(<10%) and browning at aw 0.75(>19%). The most ideal condition of the storage for red peppers was a 13∼15% water content and 60${\pm}$5% RH. The storage life for whole red peppers were 2.0 months at 40$^{\circ}C$, 13.6 months at 25$^{\circ}C$, 27.3 months at 15$^{\circ}C$, 30.0 months at 10$^{\circ}C$, and 65.0 months at -3$^{\circ}C$. During any storage period above, level of capsanthin, browning and capsaicin were changed for whole peppers. Browning appeared to be a crucial factor for marketable quality of stored red peppers. It was found that the level of capsaicin & capsanthin have a miner relationship with marketable quality for consumer. Storing red peppers in nitrogen and vacuum atmosphere packing condition was found to be better than storing them in air at various temperatures in terms of storage life and quality maintenance. The nitrogen gas packaged red peppers kept longer shelf life and better quality compared with vacuum packaging.

The enzyme activity and the micronutrient content of powdered raw meal (PRM) and powdered processed meal (PPM) were compared. PRM was made of freeze-dried cereals, fruits, and vegetables. PPM was made of the same materials as PRM, but with heat processing such as steaming, roasting and hot air drying. The activity of $\alpha$-amylase of PRM was higher than that of PPM. However there were no differences of the concentration of proximate components between PRM and PPM. The concentrations of vitamin A, C, folic acid, biotin, calcium, potassium, sodium and iron in PRM were higher than in PPM, but there were no differences in vitamins E, B$_1$, B$_2$, phosphorus and zinc. This research demonstrated that PRM retains greater nutritional value because there is higher enzyme activity and less loss of micronutrients during processing in PRM than in PPM.
