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.

The Aster tataricus is a chinese traditional medicine called “Ziwan” which has an expectorative and remediable cough action. The anti-oxidant activities of A. tataricus were investigated. The MeOH extract of A. tataricus showed strong anti-oxidant activity in the NBT(nitroblue tetrazolium) method system, and thus fractionated with several solvents in to the EtOAc, n-BuOH, CH$_2$Cl$_2$, H$_2$O fraction. The EtOAc soluble fraction exhibiting strong anti-oxidant activity was further purified by repeated silica gel and sephadex LH-20 column chomatography. (omitted)

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.

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.

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.

Growth responses of some intestinal bacteria such as bifidobacteria and Clostridium perfringens to the extracts of certain foodstuffs were investigated in vitro. Among edible mountain herbs, the extracts of several chui-na-muls (Aster tataricus, Ligularia fischeri and Aster scaber) had an inhibitory activity against C. perfringens on the agar plate and the water extract of Aster scaber worked selectively on it among intestinal bacteria. The water extract showed growth-promoting effect toward bifidobacteria such as B. adolescentis, B. animalis, B. bifidum, B. infantis and B. thermophilum in the broth culture. When the faecal inoculum was incubated in the culture with the extract, the population of C. perfringens decreased, whereas that of bifidobacteria increased by $10^3$ scale.$\beta$-glucuronidase activity in the culture with the water extract of Aster scaber digested with pepsin and pancreatin was lower than that in the control culture.
