The principal objective of this study was to develop processed food with the effect of extract from Angelica gigas Nakai by assessing the quality characteristics of cookies. Cookie samples were prepared with shredded extract from Angelica gigas Nakai at varied levels of 0, 1, 3, and 5%. The pH of dough decreased significantly with the added extract from Angelica gigas Nakai and the density increased significantly in the 5% added group(p<0.05). The spread factor decreased significantly as the added extract from Angelica gigas Nakai increased(p<0.05). The Hunter color's L value in cookies significantly decreased and the a, b values in cookies increased(p<0.05). The hardness of cookies significantly increased added extract from Angelica gigas Nakai increased(p<0.05). The acid value and peroxide value were lower in added Angelica gigas Nakai extract groups than in the control group as the storage period of cookies passed. The results of sensory characteristics demonstrated that 1% added Angelica gigas Nakai extract showed the highest degree of preference among all the items of added Angelica gigas Nakai extract(color, odor, taste, hardness, crispness and overall quality) and the added Angelica gigas Nakai extract indicated possibilities for developments of Angelica gigas Nakai extract cookies.

Takenoshin Nakai (1882-1952), Japanese taxonomist and professor of the University of Tokyo, who was one of Korean flora specialists, conducted his plant exploration from 1909 to 1942 after he completed two volumes of Flora Koreana. His collections, which are currently deposited at the University of Tokyo herbarium (TI), are important research resources. Since all collection sites were simply described in his collection sites in Romanized characters based on Japanese pronunciation, it is difficult for Korean as well as Japanese botanists to pinpoint those sites using the current or the old Korean maps. No single literature has been available regarding his collection routes and sites, although this information is essential to current plant systematic research in Korea. From this current study, all locality names were reviewed based on his own collections as well as his written literatures, and those were listed as the order of his collection dates with seven maps here.

The purpose of this study was to examine the effects of Angelica gigas Nakai on ulcerative colitis. Mice were divided into 5 groups: Control group, DSS group, 5-ASA group, 50mg/kg Angelica gigas Nakai group, 100mg/kg Angelica gigas Nakai group. Four groups, excluding the control group, were fed a 5% solution of dextran sulfate sodium(DSS) in water for 7days to induce ulcerative colitis. Each water extract was administrated orally for 7 days in 5-ASA group, 50mg/kg Angelica gigas Nakai group and 100mg/kg Angelica gigas Nakai group. 5 groups were evaluated by weight, length of intestine, weight of spleen, disease activity index(DAI), amount of cytokine IL-6 production, thickness of bowel wall and degree of inflammatory cell infiltration and intestinal tissue damage. Comparing to DSS group, 100 mg/kg Angelica gigas Nakai group showed significant suppressive effect of weight loss until 4th day of experiment while 50 mg/kg Angelica gigas Nakai group showed no significant effect of suppression. Decrease of intestinal length, enlargement of spleen, intestinal tissue damage and thickening of bowel wall were significantly suppressed in both 50 mg/kg and 100mg/kg Angelica gigas Nakai group. Also disease activity and cytokine IL-6 production were inhibited significantly. Based on this result, Angelica gigas Nakai seemed to have anti-inflammatory effect and also seemed to suppress histological changes and aggravation of ulcerative colitis.

Physicochemical and sensory characteristics of pound cake prepared with various levels of Angelica gigas Nakai powder were investigated. The pH of batter prepared with Angelica gigas Nakai powder ranged between 7.17 and 7.30 and that of the control was 7.34. The moisture content and pH of pound cakes was found to decrease with increasing Angelica gigas Nakai powder content. The specific volume of the control cake was 1.793 ml/g, that of pound cakes prepared with Angelica gigas Nakai powder was 1.806~2.026 ml/g. The baking loss rate of the control was 11.33% and that of pound cakes prepared by adding Angelica gigas Nakai powder was 10.29~6.66%. DPPH radical scavenging activity of the control group was 23.58%, whereas pound cakes prepared by adding Angelica gigas Nakai powder ranged from 38.77~77.60%. The a value of redness was increased, but L and b value were decreased significantly by the addition of Angelica gigas Nakai powder. The hardness and brittleness of the pound cakes were increased significantly by the addition of Angelica gigas Nakai powder. Sensory evaluation scores in terms of flavor, taste and overall preference for pound cakes were higher for the 2% substituted sample group than for any of the others. The results of this study suggest that the addition of 2% Angelica gigas Nakai powder was the best substitution ratio for pound cake.

The effects of Angelica gigas nakai powder on bread quality during storage period were evaluated. Breads were prepared by the addition of 0, 0.5, 1, 2, 3, 5 and 10% of Angelica gigas nakai powder to flour of the basic formulation. The moisture, crude protein, crude fat and crude ash contents of the bread decreased by increasing amounts of the Angelica gigas nakai powder were the lowest in the control group. There were no significant difference in pH of the bread among each experiment groups. The weight of bread increased with increasing Angelica gigas nakai powder concentration, while the volume of dough decreased. In color values, with increase of Angelica gigas nakai powder concentration, L value decreased in the crust and crumb, but a and b values increased. As the results of texture, hardness, gumminess and chewiness were increased with increase of Angelica gigas nakai powder concentration, but adhesiveness, springiness and cohesiveness were decreased. Softness in the crumb stored for 1 or 7 days was the highest for the bread made with 2% Angelica gigas nakai powder, and chewiness was the lowest for the bread made with 5% Angelica gigas nakai powder. The water activity in the bread stored for 3 days was the highest for the breads made with 2% and 3% Angelica gigas nakai powders. After 7 days, the water activity tended gradually to decrease. In the results of sensory evaluation, the quality of the 0.5% or 1% Angelica gigas nakai powder bread showed the highest in taste and flavor. The color, taste, flavor, appearance, texture, and overall acceptability of the bread decreased with the increasing Angelica gigas nakai powder content. Considering the able outcome, the addition of Angelica gigas nakai powder by 0.5% and 1% is thought to play a role as a functional breads, along with the improvement of quality.

T. Nakai, who wrote Flora of Koreana vol. II in 1911, cited V. L. Komarov's collections and listed more than 120 specimens with ca. 65 localities. All collection sites cited were described in the Romanized characters based on the Russian pronunciation. Therefore, it is very difficult to pinpoint those sites using the current or old version of Korean map. From this study, many names were reviewed based on other studies (both the Russian version and the Japanese translated version) and records (e.g. specimen label) and presented based on the current provinces with local names, the Chinese character, the GPS data and the first page of citation.

Tstomu Ishidoya (1891-1958), a Japanese taxonomist and pharmacognosist, conducted his plant explorations on the Korean peninsula from 1911 to 1943. Especially from 1912 to 1923 Ishidoya, as a governmentemployee of Chosen Governor-General collected numerous specimens of woody plants which were later studied by T. Nakai. Collection numbers totalling 6,487 (= collections) were recorded according to Nakai's studies, while only 1,350 speciemens are confirmed to be preserved now in three Japanese herbaria (Tokyo Universtiy, Kyoto University and National Museum of Nature and Science). All collection sites were described by Nakai using romanized characters with Japanese pronunciation. For this study, one hundred seventy three locality names were reviewed using those of Ishidoya's specimens that are deposited at TI, KYO, and TNS; the database, Korean Biodiversity Information System (http://www.nature.go.kr), and the articles and literature of Nakai and Ishidoya. These are listed in the order of his collection dates.
