To produce several high-quality species of Chwinamul (Aster scaber, A. Tataricus, Ligularia fischeri), leaves of the plants grown in different natural habitats were anlayzed. Contents in vitamin C and $\beta$-carotene were generally higher in plants grown in the field. However, Aster scaber picked form Yongwol and A. tataricus from Mt.Taryong contained relatively higher vitamin c and $\beta$ carotene. Crude protein and fat contents varied depending on the growing area. Ca content was markedly higher in the plants grown in the natural havitats.

In an ongoing investigation into anti-oxidative compounds from natural products, the EtOAc soluble fraction of Aster tataricus L. (Compositae) showed significant anti-oxidative activity on the NBT superoxide scavenging assay. By means of an activity-guided purification, three flavonoids, kaempferol (1), quercetin (2), astragalin (3) and one monoterpene glycoside, shionoside A (4) were isolated. Their structures were determined spectral analyses. Compounds 2 and 3 showed potent antioxidative activity, while, compounds 1 and 4 were inactive $IC_{50}$>120${\mu}g/mL$. In addition, these compounds were examined for the effect of interleukin-6 (IL-6) production in TNF-${\alpha}$ stimulated MG-63 cell. Compounds 1-3 showed negligible inhibitory activity against IL-6 production in $TNF-{\alpha}$ stimulated $MG-6{\beta}$ cell, and compound 4 was inactive.

This study evaluated the dermal cytotoxicity of sodium bromate (NaBrO₃) and the protective effect of Aster tataricus L. (AT) extract against NaBrO₃-induced cytotoxicity in the cultured NIH3T3 fibroblasts. For this study, it was done the antioxidative effects such as electron donating (ED) activity and lipid peroxidation (LP) activity as well as cell viability. NaBrO₃ significantly decreased cell viability in a dose-dependent manner and its XTT₅₀ value was measured at a concentration of 54.4 μM in these cultures. The cytotoxicity of NaBrO₃ was determined as highly-toxic by Borenfreund and Puerner's toxic criteria. The quercetin, antioxidant significantly increased cell viability against NaBrO₃-induced cytotoxicity. Regarding the protective effect of Aster tataricus (AT) L. extract on NaBrO₃-induced cytotoxicity, AT extract significantly increased the cell viability, the ED ability and the inhibitory ability of LP. From these findings, it suggested that the oxidative stress is involved in the cytotoxicity of NaBrO₃, and AT extract effectively protected NaBrO₃-induced cytotoxicity by antioxidative effects. Conclusively, the natural component like AT extract may be a putative therapeutic agent for the diminution or treatment of the cytotoxicity correlated with oxidative stress like hair dye component, NaBrO₃.

This experiment was carried out to investigate the effect of nitrogen form in the Hoagland nutrient solution on the growth of Farfugium japonicum, Aster tataricus and Chrysanthemum boreale. The nitrogen form of Hoagland nutrient solution was modified to $NH_4{^+}(100%),\;NO_3{^-}(100%),\;and\;NH_4{^+}+NO_3{^-}(50%+5%)$ for this study. In the treatment of $NO_3{^-}\;and\;NH_4{^+}+NO_3{^-}(1:1)$, F. japonicum showed the best growth, especially in fresh weight. With the treatment of $NO_3{^-}$, shoot and root fresh weight of A. tataricus and C. boreale were increased. The activity of nitrate reductase and the concentration of chlorophyll and nitrate were increased with $NO_3{^-}$ treatment in all these plants.

Research was initiated to investigate vegetation coverage and growth of main herbaceous flowers under low maintenance condition like a wild state. Eleven entries were comprised of 1 annual, 2 biennials and 8 perennials from widely used herbaceous flowers in Korea. Vegetation coverage and germination rate were high on annual and biennials when compared to perennials. Callistephus chinensis showed high vegetation coverage but lasted only for a year in 2001 and disappeared in 2002 as an annual. Oenothera odorata and Oenothera lamarckiana were also high vegetation coverage species with persistent only for two years as biennials. Therefore, these species should not be used in a large amount for ecological restoration when mixed with perennials because of affecting the vegetation coverage of perennials. There were considerable variations in vegetation coverage with perennial herbaceous flowers : Lotus corniculatus and Taraxacum platycarpum-high vegetation coverage species, Platycodon grandiflorum, Aster tataricus and Aster koraiensis-medium vegetation coverage species, and Aster yomena, Patrinia scabiosaefolia and Chrysanthemum indicum-low vegetation coverage species. Growth types of herbaceous flowers tested in this research were divided into 4 types : Callistephus chinensis, Oenothera lamarckiana and Aster koraiensis-wide leaf and tall type, Aster tataricus, Patrinia scabiosaefolia, Oenothera odorata, Taraxacum platycarpum, and Aster yomena-medium leaf and medium tall type, Platycodon grandiflorum-fine leaf and dwarf type, and Lotus corniculatus-fine leaf and tall type.

A comparison of essential oils composition of Aster tataricus L. (gaemichwi), Ligularia fischeri (gomchwi), Solidago virga-aurea var. asiatica Nakai (miyeokchwi), and Aster scaber (chamchwi) was performed by gas chromatography and mass spectrometry for the identification of volatile flavor characteristics in chwi-namuls. The essential oils were extracted by the hydro distillation extraction method. One hundred volatile flavor components were identified from gaemichwi essential oil. ${\alpha}$-Pinene (11.5%) was the most abundant compound, followed by myrcene (8.9%) and ${\beta}$-pinene (7.5%). Ninety-one volatile flavor components were identified from the essential oil of gomchwi. Aromadendrene (14.8%) was the most abundant component, followed by ${\beta}$-caryophyllene (7.6%) and 1-methyl-4-(1-methylethylidene)-cyclohexene (7.3%). Ninety-five volatile flavor constituents were detected in the essential oil of miyeokchwi, moreover, spathulenol (15.7%) was the most abundant component. Ninety-six volatile flavor constituents were detected in the essential oil of chamchwi. Epi-bicyclosesquiphellandrene (21.9%) was the most abundant component, followed by ${\beta}$-caryophyllene (9.5%) and ${\delta}$-terpinene (8.9%). The essential oil composition of gaemichwi was characterized by a higher contents of pinenes. The essential oil composition of gomchwi can be easily distinguished by the percentage of aromadendrene. Spathulenol and epi-bicyclosesquiphellandrene were regarded as the characteristic odorants of miyeokchwi and chamchwi, respectively.

Objective : Alzheimer's disease (AD) is a geriatric dementia that is widespread in old age. With an aging populace, AD is a looming problem in public health service. Alzheimer's disease is characterized by specific neuronal degeneration in certain areas of the brain. Mutations and abnormal expression of several genes are associated with ${\beta}-amyloid$ deposits and Alzheimer's disease; among them APP, PS1, and PS2, SOD, free radical, ROS. Methods:We studied herbal medicines that have a relationship to brain degeneration. From pre-modern times, although a variety of oriental prescriptions of Aster tataricus have been traditionally utilized for the treatment of AD, their pharmacological effects and action mechanisms have not yet been fully elucidated. Result : Based on morphological observations by phase-contrast microscope, TUNEL assay and MTT in the culture media, $H_20_2-induced$ cell death was significantly inhibited by Aticus. We examined by ROS formation, catalase activity and GSH activity. We studied the protective effect and inhibitory effects of neurotoxicity in $H_20_2-induced$ PC-12 cells by Aticus. Findings from our experiments show that Aticus inhibits apoptosis, which has neurotoxicities and cell damage in PC-12 cells. In addition, treatment with Aticus ($>25{\mu}g/ml$ for 6hrs) partially prevented $H_20_2-induced$ cytotoxicity in PC-12 cells, and induced a protective effect. Conclusion : As the result of this study, in the Aticus group, the apoptosis in the nervous system was inhibited, protected against the degeneration of PC-12 cells by $H_20_2$. Taken together, Aticus exhibited inhibition of $H_20_2-induced$ apoptotic cell death. Aticus was found to induce protective effect on GSH and catalase in PC-12 cells. Based on these findings, Aticus may be beneficial for the treatment of AD.

Five edible mountain vegetables(Saussurea sp. Aster tataricus, A. scaber. Synurus deltoides, Ligularia fischeri) were investigated on the basis of amplified DNA polymorphisms resulted from PCR (polymerase chain reaction) analysis. The sampled plants consisted of 38 individuals in 5 taxa. Only 10 primers out of 62 primers (60 random [10-mer] primers, two 15-mer [M13 core sequence, and (GGAT) sequence]) tested gave rise to polymorphisms in all of the tested plants, producing 176 DAN fragments amplified. Intraspecific polymorphisms found in each taxa showed intraspecies constancy (31.1-61.1%) in the banding patterns of individual plants: Saussurea sp. 31.1%, 15 bands, Aster tataricus, 40.9%, 18 bands, A. scaber. 38.5%, 15 bands. Synurus deltoides, 34.7%, 17 bands, and Ligularia fischeri, 61.1%, 22 brands, respectively. All five species were well classified from each other at the 0.93 level of similarity index value. Intraspecific and interspecific variations were appeared at the levels ranging from 0.62 to 0.99. Based on these results, our PCR analyses support the previous data derived from external morphology of the 5 edible mountain vegetables, but very low levels o intraspecific variations were detected in all of these taxa.
