The fusel oils and the volatile flavor compounds of two potato sojues, one of which was produced with the traditional distillation apparatus(soju-gori) and the other, with the reduced pressure distillation system, were examined. The fusel oil content was high in the potato soju that was distilled under reduced pressure (potato soju(II)). The relative ratio of the isoamyl alcohol to the isobutyl alcohol and the n-propanol was 3.1:0.8:1.0 in the potato soju that was distilled with soju-gori (potato soju(I)), and 4.0:1.2:1.0 in potato soju(II). The chromatograms of the volatile components apparently differed between potato soju(I) and potato soju(II). Potato soju(I) contained four kinds of alcohol, six kinds of ester, n-valeraldehyde, and acetic acid. Potato soju(II) contained seven kinds of alcohol, 14 kinds of ester, two kinds of aldehyde, acetic acid, and three other compounds. Potato soju(II) significantly scored higher for flavor property than potato soju(I).

Objective : This study was performed to compare anti-inflammation, anti-oxidation and anti-bacterial effects of Ligustici Rhizoma (LR) extracted with two kinds of solvents, ethanol and distilled water. Methods : It is prepared two kinds of LR extracts 20, 50, 100 ${\mu}l/mg$ by first. MTT assay way to measure cytotoxicity is formed in Raw 264.7 cell. The anti-inflammation effect is measured by ability to inhibit production of NO in Raw 264.7 cell. The anti-oxidation effect was measured by DPPH Radical scavenging ability in HaCaT cell. The anti-bacterial effect was measured by inhibition zone diameter on Propionibacterium acnes. Results : 1. LR (20 ${\mu}l/mg$) extracted with ethanol was showed 80% cytotoxicity, LR (50 ${\mu}l/mg$) extracted with ethanol and LR (20, 50 ${\mu}l/mg$) extracted with water were showed 70% cytotoxicity, LR (100 ${\mu}l/mg$) extracted with ethanol and LR (100 ${\mu}l/mg$) extracted with water were showed 60% cytotoxicity in Raw 264.7 cell. 2. LR (100 ${\mu}l/mg$) extracted with ethanol was showed more significantly inhibitory effect on NO production than the water extraction. 3. Two kinds of LR extraction groups did not show significantly scavenging effect of DPPH radicals. 4. Two kinds of LR extractions did not have a inhibitory effect on Propionibactrium acnes. Conclusion : Two kinds of LR extracts have not cytotoxicity, statistically significant ability to scavenge DPPH radicals and effect to inhibit Propionibactrium acnes. LR extracted with ethanol only have a little effect to inhibit NO production. This study proposes that LR extracted with ethanol is more effective in anti-inflammation.

The purpose of this study is to provide and suggest useful data in use of kinds of violet that is resulted from general color images of violet. The origin, history, and general images of kinds of violet were studied, and were classified vased on documcntary reviews. Findings are as follows: 1) The kinds of violet were used purple, violet, mauva, and magenta in the order of appearance of its color names and the categories of violet had been extended from dark reddish violet to affilicated colors of bright violet by development in synthetie dyestuff. 2) The kinds of violet has neutral characters due to the combination of two extreme colors, red and blue, and thereby revealing voth attreibutes in terms of symbolic, emotional, and spychological features of colors. The positive images in kinds of violet can be classified as nobleness, holiness, mysteriousness, sleep/sedation, sensuality, femininity, fragrance, and the negatibely classified images are weakness, sadness, maelancholiness, death(for example, the mourner's gard in royal families), symbols of moral corruption, and superstition.

This article examines the types of tteok (Korean rice cake) recorded in 21 old literatures of the Joseon dynasty (1392-1909) according to its main ingredients. Tteok varieties of the Joseon dynasty were categorized into jjin-tteok, chin-tteok, jijin-tteok, salmeun-tteok and guun-tteok and their changes in cooking method were discussed from the early to late eras of the Joseon dynasty. These can be summarized as follows. In the early, middle and late eras of the Joseon dynasty, there were 1, 15 and 84 kinds of tteok using non-glutinous rice as the main ingredient, and 6, 24 and 120 kinds using glutinous rice, respectively. Tteok using wheat flour was not found in the early Joseon dynasty, whereas 6 and 32 kinds were found in the middle and late eras, respectively. There were 1, 4 and 5 kinds of tteoks using buckwheat, and 5, 11 and 19 kinds using other ingredients such as yam, barley, elephant's ear, oat, and arrowroot flour, in the early, middle and late eras, respectively. The frequency of the main ingredient increased in the order of glutinous rice>non-glutinous rice>wheat flour>other ingredient>buckwheat flour during the Joseon dynasty and the ratio of tteoks using non-glutinous and glutinous rice flours was 1:1.5. The number and types of tteok were noted to increase abruptly throughout the Joseon dynasty. This may be associated with the commercial industrial development that prevailed in the late Joseon dynasty. Further study will be conducted on their recipes and ingredients recorded in these old literatures to develop a standardized recipe for the globalization of tteok.
