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.

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.

The antioxidant activities of water extracts from wild vegetables such as Ligularia fischeri (GC), Capsicum annuum L. (GCY), Aster scaber (CNM), Petasites japonicus S. et Z. Max (MYD), Ipomoea batatas L. (Lam) (GGM) were evaluated and compared with water extracts from freeze dried block. The antioxidant properties of water extracts from wild vegetables and their freeze dried block were evaluated using different antioxidant tests; 2.2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging, hydroxyl radical scavenging and nitrite scavenging activities. The water extracts from wild vegetables were found to have a higher total phenolic content than water extracts from freeze dried block. Total phenolic contents of water extracts from GC, GCY, CNM, MYD, and GGM were $471.66{\pm}3.52\;{\mu}g/mg,\;141.33{\pm}2.51\;{\mu}g/mg,\;177.33{\pm}2.88\;{\mu}g/mg,\;238.66{\pm}9.50\;{\mu}g/mg\;and\;122.67{\pm}3.51\;{\mu}g/mg$, respectively. At the concentrations of 1000 ppm, water extracts from GC, GCY, CNM, and GGM showed higher activities than water extracts from their freeze dried block on DPPH radical scavenger activity. The activity of water extracts from CNM, GC, GCY, MYD, and GGM were 90.9%, 89.9%, 76.6%, 71.1%, and 57.4%, respectively. When 10000 ppm of GC, GCY, CNM, MYD, and GGM water extracts tested for hydroxyl radical scavenging activity, activities were increased by 38.8%, 33.4%, 35.9%, 34.3%, and 33.8%, respectively and a similar effect was found with water extracts from GCY, CNM, and GGM freeze dried block at 10000 ppm concentration. However, the water extracts from GC and MYD was slightly more effective than freeze dried block extracts. The water extracts from wild vegetables and their freeze dried block had effective DPPH radical scavenger activity and hydroxyl radical scavenging activity at all tested concentrations. Nitrite scavenging activity of GC water extract significantly increased in a dose-dependent manner and the extract had higher nitrite scavenging activity than extracts freeze dried block extracts. We found that freeze dried block maintained antioxidant activities of the wild vegetables.

This study was conducted to obtain the basic data on the development of resources of wild edible greens, and the industrialization of the marketing of fresh wild vegetables. We have also investigated the distributing factors at five-day traditional markets (Taebaek, Hongcheon and Hoengseong) in Gangwon district, and in Jeonnam district (Naju, Damyang and Jangseong), in May and June 2007. At each market, there were 34 to 49 diverse shops selling fresh wild vegetables except at Naju, where there were 22 shops. Between 27 to 29 kinds of fresh wild vegetable were on sale at the traditional markets in Gangwon district, and 15 to 19 kinds were on sale along with many horticultural plants in Jeonnam district. Fresh wild vegetables including Aster scaber, Petasites japonicus, Pteridium aquilinum var. latussculum, Malva verticillata, leaves of Perilla frutescens, Lactuca sativa, leaves of Capsicum annuum, and Oenanthe javanica were on sale in the markets in both districts. Those selling fresh wild vegetables were typically over 51 years of age (88%), and among these over 66.4% were over 61 years old. Less than 6 kinds of fresh wild vegetable accounted for over 72.1% of the vegetables sold. Edible wild greens were mainly packed in vinyl bags (over 77%).

For screening antimutagenic effects, the effects of 95 medicinal plants on the mutagenicity of aflatoxin $B_1$ $(AFB_1)$ and benzo(a)pyrene [B(a)P] were investigated using the SOS chromotest with Escherichia coli PQ37. The mutagenicity induced by $AFB_1$ or B(a)P was reduced over 26% by 2 kinds and 8 kinds of medicinal plant, respectively. Eight plants (Bupleurum falcatum, Corydalis ternata, Gasfrodia elata, Ostericum koreanum, Pinellia ternatia, Poncirus trifoliata, Prunus armeniaca and Rehmannia glutinosa) were also shown to have inhibitory effects on both $AFB_1$ and B(a)P. The mutagenicity induced by $AFB_1$ or B(a)P was increased over 20% by 46 kinds and 2 kinds, respectively, and 8 medicinal plants (Chrysanthemum indicum, Cinnamomum cassia, Cyperus rotundus, Morus bombycis, Patrinia scabiosaefolia, Petasites japonicus, Polygonum multiflorium, Thyja orientalis) increased significantly the mutagenicity of both mutagens. However the 8 plants themself did not show the mutagenicity in SOS Chromotest with S-9 mix alone. This result suggests that the above 8 plants may have the co-mutagenic activities. In two bacterial mutation system, SOS Chromotest and Ames test, the mutagenic or antimutagenic activities of some medicinal plants wire similar except Ostricum koreanum, Eugenia caryophyllata and Scutellaria baicalensis.
