  • The purposes of this dissertation were to examine relativity between growth characteristics factors and develop the model of growth characteristics. In the result of statistical summaries of the factors in growth characteristic, the highest level of correlation was in plant height, plant width, petiole and chlorophyll in the case of Artemisia iwayomogi; leaf length, in the case of A. stolonifera;, leaf width, of A. princeps var. orientalis;, diameter, of A. feddei;, leaf thickness, of A. iwayomogi, A. princeps var. orientalis, A. montana, A. stolonifera, A. sylnatica; leaf length and leaf width of the other species. In the case of correlation analysis, leaf width and diameter were most correlative in A. capillaris;, plant height and plant width, in A. montana; plant height and leaf width, in A. stolonifera; leaf length and leaf width, in other species. The results of model analysis of growth characteristics were as follows. A. capillaris proved to be about $79.4\%$ effective ; A. princeps var. orientalis, about $91.7\%$ ; A. montana, about $70.3\%$ ; A. iwayomogi, about $49.0\%$ ; A. stolonifera, about $72.5\%$; A. sylnatica, about $75.0\%$;, A. feddei about $60.4\%$ ; A. rubripes about $54.0\%$.

  • Somatic chromosome numbers for 20 taxa of Korean Artemisia L. were investigated for the purpose of classification. Somatic chromosome numbers of treated taxa were 2n = 16, 18, 34, 36, 50, 52, 54, and therefore their basic chromosome numbers were x = 8, 9, 10, 13, 17. The chromosome number of A. japonica var. angustissima is being reported for the first time in this study. The chromosome numbers of 13 taxa were the same as in previous reports; A. capillaris (2n = 18), A. japonica var. hallaisanensis (2n = 36), A. japonica subsp. littoricola (2n = 36), A. annua (2n = 18), A. carvifolia (2n = 18), A. fukudo (2n = 16), A. keiskeana (2n = 18), A. stolonifera (2n = 36), A. sylvatica(2n = 16), A. selengensis (2n = 36), A. montana (2n = 52), A. lancea (2n = 16), A. sieversiana (2n = 18); however, the chromosome numbers of 6 taxa were different; A. japonica var. japonica (2n = 18, 36 vs 2n = 36), A. sacrorum (2n = 18, 54 vs 2n = 54), A. rubripes (2n = 16, 34 vs 2n = 16), A. indica (2n = 34, 36 vs 2n = 34), A. codonocephala (2n = 18, 50, 54 vs 2n = 50), A. argyi (2n = 34, 36, 50 vs 2n =34). The somatic chromosome numbers of Korean Artemisia are thought to be good characteristics for classifying some taxa such as A. japonica var. japonica, A. sacrorum, A. codonocephala, A. argyi, A. montana, A. sylvatica.

  • Characteristic stereostructures of farnesyl protein transferase (FPTase) inhibition materials isolated from Artemisia sylvatica and regioselectivity of biogenic Diels-Alder reactions between dehydromatricarin molecules A and B were examined quantitatively. Results revealed that the major reaction of frontier molecular orbital (FMO) interaction proceeds through charge-control reaction between LUMO of A16, dienophile and HOMO of B1, diene, and the isolated 8-acetylarteminolide and artanomaloide were minor products. FPTase inhibition activity and hydrophobicity of 8-acetylarteminolide were $pI_{50}=3.75$ and logP=2.62, respectively. FPTase inhibition activity of 8-acetylarteminolide was higher than those of artanomaloide and dehydromatricarin.

  • Two polysaccharides, ACP-UMP and ACP-ULF, were purified from the aerial part of Artemisia capillaris by anion-exchange chromatography, ultrafiltration, and gel filtration chromatography. The polysaccharides appeared to be homogenious from the results of HPLC. The molecular weights of ACP-UMF and ACP-ULF were estimated to be 16305.92 D and 3292.26 D, respectively, by MALDI-TOF MS. The sugar compositions were determined by GC to be arabinose 10.05%, xylose 1.67%, mannose 5.45G, galactose 39.06%, glucose 15.43% for ACP-UMF and arabinose 11.60%, xylose 11.15%, mannose 6.37% galactose 32.47%, glucose 18.35% for ACP-ULF. A polysaccharide, SP-M was determined to be 2462.52 D by MALDI-TOF MS. SP-M consisted mainly of rhamnose 36.49%, arabinose 29.00%, and glucose 19.38%. Incubation of CCl4-intoxicated hepatocytes with ACP-UMF reduced the levels of glutamic pyruvic transaminase (GPT) and cellular malondialdehyde (MDA) to 62.8% and 23.8%. ACP-ULF also reduced the levels of GPT and MDA to 46.1% and 38.1% and 26.3%, respectively.

  • As a part of development of traditional foods, mugwort boogag and dry laver boogag were fried insoybean oil, and BHA or tocopherol-added soybean oil. They were wrapped up in opp vinyl film, and preserved at $4^{\circ}C(RH{\;}40{\pm}5%){\;}and{\;}25^{\circ}C(RH{\;}80{\pm}5%)$. During the storage of bobogags, acid value, peroxide value, and TBA value were investigated. Changes of sensory evaluation and texture profile were also examined. Boogags were manufactured by washing the raw materials. drying in the shade, mixing them with glutinous rice flour, and hot-air drying up it to 13 % of moisture contents after dryed it up to 80% of moisture contents on dry table for 23days, in order. These boogags were packaged to manufacture goods with dryed state or fried at $160^{\circ}C$ for 10 sec. Acid value, peroxide value, and TBA value of boogags which preserved at $4^{\circ}C$ generally appeared lower than at $25^{\circ}C$. As storage time goes by, moisture contents of bobogagas preserved at $25^{\circ}C$ increased and its quality were gradually deteriorated. When the boogags were fried in BHA(0.01%) and tocopherol (0.01%) added soybean oil, changes of acid value, peroxide value, TBA value were generally low. During the storage of bobogagas antioxidant effect of BHA was higher than that of tocopherol. Texture was inclined to decrease as storage time goes, by that of boogags preserved at $4^{\circ}C$ was a little more satisfactory. Hardness was also high.
