This study evaluated the antioxidant activity and quality characteristics of rice cookie with added butterbur powder in a ratio of 0, 5, 10, 15, and 20% to confirm the possibility of butterbur as a functional food. The moisture content, spread factor, leavening rate, and hardness of rice cookies increased with an increase in the amount of butterbur powder; whereas a decrease in the pH and baking loss rate was observed. The L and b values decreased as the amount of butterbur powder increased, but the value was the lowest when 5% of butterbur powder was added. The sensory liking score showed the highest preference for 10% butterbur powder regarding appearance, flavor, taste, texture, and overall preference. In the principal component analysis (PCA), the addition of 10% butterbur powder positively affected the measure of food acceptance in terms of organoleptic properties of butterbur. Besides, as the amount of added butterbur powder increased, the antioxidant activity of rice cookies increased. Based on these results, it appears that the addition of butterbur powder to rice cookies in a 10% ratio can produce rice cookies with excellent antioxidant activity, overall quality, and high preference.

We evaluated the effects of butterbur (Petasites japonicus Maxim) addition to the diet on lipid profiles and antioxidant biomarkers such as total glutathionine, TBARS value, carbonyl value, GPx, GR, SOD and paraoxonase activity in the plasma or liver of mice. The distribution of body fat deposition, total cholesterol (TC) contents, and atherogenic index in the plasma were significantly decreased in the butterbur group. The levels of GSH and the activity of GR and SOD were significantly higher in the liver of the butterbur group than in that of the control group. Lipid oxidation of the liver and kidney and protein oxidation of the liver and heart were decreased in the butterbur group. Additionally, the DNA damage, as determined using the comet assay (single cell gel assay) with alkaline electrophoresis and as quantified by measuring the tail length (TL), was decreased in the butterbur group. The results of the present study showed that a diet with added butterbur exerts degenerative disease-protective effects on oxidative DNA damage and lipid peroxidation.

The antioxidant activities of the extracts of butterbur (Petasites japonicus) derived from different extraction methods were investigated. SOD (superoxide dismutase)-like activity differed according to the extraction solvents, showing a greater antioxidant effect with ethanol solvent than that of water. Ethanol extracts of butterbur leaves showed higher SOD-like activity of 96.7% than those of water extracts. The contents of polyphenolic compounds were higher in water extracts than those in ethanol extracts. The highest content of polyphenolic compounds was 223mg/g dry weight for butterbur leaves. EDA of butterbur roots was 61.5% in the water extract and EDA in butterbur leaves was 34.9% in the ethanol extract. The anticancer effects with the extracts of butterbur were experimented by fractionations with different solvents. 41.9% of the growth of stomach cancer cells, SNU-719, were inhibited and also 72.7% of the growth of liver cancer cells, Hep3B, were inhibited by the butanol fractions of butterbur, while not affecting the growth of normal cell, DC 2.4.

The effects of food restriction on the fecal microflora, moisture, pH, indole, ${\beta}$-glucosidas, and ${\beta}$-glucuronidase in rate were studied for 4 weeks. Four groups of rats for feeding was allocated to the following experimental trials : (1) control containing 1% cellulose, (2) control with food restriction, (3) treatment of diet containing butterbur, (4) treatment of butterbur combined with diet restriction. Treatment of butterbur combined food restriction significantly (p<0.05) reduced the growth of Bacteroides, Peptococus, Streptococcus, Staphylococcus, and Escherchia coli, respectively. No remarkable changes in the ${\beta}$-glucosidase and ${\beta}$-glucuronidase activities were observed but indole content significanlty decreased. Based on these results, treatment of butterbur combined with diet restriction in rats had a significantly effect for preventing the growth of those pathogenic microorganims.

Change on the structural carbohydrate(several fiberous components) was determined by vegetables(crown daisy and butterbur)-cultivated in Ulsan, Kyungnam, Korea-as its stage of maturity developed. Samples were separated into leaf and stem, which were dried at 7$0^{\circ}C$ for 24hr, and ground to pass a 1mm screen. They were subjected to moisture, crude protein, crude fat and several dietary fiber-DF(dietary fiber, include unavaible components), NDF(neutral detergent fiber), ADF(acid detergent fiber), lignin, hemicellulose, cellulose and protein corrected NDF(c-NDF), IDF(indigestible fiber, include lignin, hemicellulose and cellulose). In general, structural carbohytrate(several dietary fiber) of vegetable was affected by the growth stage. In case of crown daisy and butterbur, dietary fiber in leaf was higher than DF in stem.

This study was performed to provide reference materials for the vegetable cultivating farmhouses by investigating profit and marketing situation for the folk vegetables. The survey areas covered 10 cities and counties including Kumsan, 72 farmhouses, and 8 crops including buffterbur and wild rocambole. As a result, the cultivated area of folk vegetables was increased as much as 13.7%, however, marketing cost was higher than that of horticultural crops, because they were not accessed to wholesale market. It was that the optimal period to sell the folk vegetables was shown like Jan. - Feb. for butterbur and day lily, Nov. - Dec. for wild rocambole, and Oct. - Nov. for kind of lettuce respectively. As the result of analyzing economical efficiency, the net profit per 0.1 ha was amounted to 3,438,000 won for butterbur, 3.291,000 won for wild rocambole 1,712,000 won for day lily, and 1,464,000 won for fatsia shoots. Besides, these four crops occupied more than 60% in cultivation area, and their profit was high. Therefore, it is necessary to foster them with special crops in Chnugnam area. The crops that require more labor time were such crops as 632.9 hours for day lily, 584.3 hours for butterbur, and 409.2 hours for fatsia shoots, whereas the crops that required less labor time were such field crops as 219.2 hours for fragrant edible wild aster and 233.8 hours for kind of lettuce.

In order to produce young leaf of butterbur(Petasites japoflicus MAX.) in early spring, the planting date and relationship between abscisic acid(ABA) content and dormancy were investigated. Under open field condition, the dormancy of rootstock was initiated in the beginning of October, was the deepest in the middle of November and was completely broken in the end of December. When those periods were converted by the low accumulation hour below 5$^{\circ}C$, 900 hours were required approximately. This means that the rootstock needs for dormant breaking necessitates under the low temperature. In relationship between growing period and ABA content, the ABA in root-stock did not exist during maximum growing period, from April to September. This means that the ABA together with other substances in rootstock can be transferred to the shoot part with sprouting. While shoot part withered by decreacing the open field temperature since October, the ABA intiated to exist in rootstock. This means that the ABA in the shoot part can be transferred to the rootstock part. Therefore, it was concluded that the ABA which has been known that inhibiting growth and inducing dormancy was closely related with dormancy of rootstock.

1. Objectives We know that the origine of the pe-tsai is from 백채(白菜; pronounced as bak-tsai, meaning white vegetable). But some literatures said that the japanese butterbur(Petasites japonicus (Sieb. et Zucc.) Maxim) is from 백채(白菜;: pronounced as bak-tsai), too. These two words have same origin. It makes us get into a mess. So We are about to study the origine of the pe-tsai more. Also, we investigated its historical origin, properties and Sasang constitutional medicine's efficacy. 2. Methods We reviewed farmings(e.g. 山林經濟, 林園經濟法), dictionarys(e.g. 訓蒙字會), encyclopedia(e.g. 物名攷), books on herbs and medicines to summarize literatures about the pe-tsai. 3. Results and Conclusions (1) The origin of term, pe-tsai is sung, named after a pine tree(松), chineses character pronounced as song) which we can see throughout a year. Also, pe-tsai was called white vegetables(白菜, pronounced as bak-tsai) because its appearance is green and white. Therefore, the pronounciation of sung derives from its character and we also say bak-tsai(白菜), which came from its looks. (2) Today we pronounce pe-tsai inro bae-tsu(배추) in korean. There are pronunciational developments of this word : bak-tsai(白菜) $\to$ bae-tsae $\to$ bae-tsa $\to$ bae-tsa $\to$ bae-tsae(배채) $\to$ bae-tsu(배추). (3) Our ancestor used bak-tsai(白菜) as the name of japenese butterbur, which was different from China. The latter times of Joseon(조선), however, sometimes bak-tsai(白菜) meant pe-tsai. After the year of 1800, bak-tsai(白菜) only meant pe-tsai. So when we try to translate our ancestor's books, we must examine carefully their published year. (4) Pe-tsai is used for baby's erysipelas, boil, fever in the chest, thirst after alcohol drinking and kind of diabetes. It helps digestive organs as well. Pe-tsai is used for stress, fever in the chest and cough with fever of Soyangin and Tayangin in Sasang Constitutional Medicine.
