In Peucedanum japonicum and Aster tataricus L. chlorogenic acid was identified by methods of P.P.C. and T.L.C. $L-Phenylalanine-U-^{14}C\;and\;sodium\;acetate-2-^{14}C$ were administered to Peucedanum japonicum, $L-Tyrosine-U-^{14}C$ to Aster tataricus and $caffeic\;acid-carboxyl-^{14}C\;and\;L-tyrosine-U-^{14}C$ to Fagopyrum esculentum $M_{OENCH}$. The incorporation of each compound into chlorogenic acid was compared. $L-Phenylalanine-U-^{14}C$ showed higher incorporation to chlorogenic acid than sodium $acetate-2-^{14}C$ in Peucedanum japonicum. $Caffeic{\;}acid-carboxyl-^{14}C$ was higher to chlorogenic acid than $L-tyrosine-U-^{14}C$ in Fagopyrum esculentum. $L-Tyrosine-U-^{14}C$ was comparatively low in Aster tataricus.

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.

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.

This experimental study was done to research effects of a number of extract on the anti-allergic effect. The results were obtained as follows: 1. In effect of herb-extract on compound $\frac{48}{80}$-mediated histamine release from Evans blue skin assay, Isatis Japonica Miquel, Dictamnus dasycarpus Turcz, Spirodela polyrhiza, Cimicifuga heracleifolia, Bupleurum chinense, Magnolia liliflora, Forsythia koreana, Aster tataricus L., Xanthium strumarium L.(MtOH), Trichosanthes kirilowii, Phellodendron amurense Rupr, Schizonepeta tenuifolia Var, Betula platyphylla show considerable visible anti-allergic effect. In the result of quantification of histamine induced compound $\frac{48}{80}$, Spirodela polyrhiza, Isatis Japonica Miquel, Trichosanthes kirilowii, Bupleurum chinense, Forsythia koreana inhibit histamine release effectively. 2. In effect of Herb-Extract on compound $\frac{48}{80}$-mediated histamine release from RPMC, Spirodcla polyrhiza, Cimicifuga heracleifolia inhibit histamine release effectively. 3. In effect of Herb-Extract on anti-DNP IgE-mediated histamine release from Evansblue skin assay. Spirodela polyrhiza, Cimicifuga heracleifolia(0.1mg/ml). Forsythia koreana, Aster tataricus L., Xanthium strumarium L.(0.1mg/ml), Trichosanthes kirilowii(0.1mg/ml) show considerable visible anti-allergic effect. In the result of quantification of histamine induced anti-DNP IgE, Spiradela polyrhiza, Isatis Japonica Miquel, Trichosanthes kirilowii, Bupleurum chinense, Forsythia koreana inhibit histamine release effectively 4. In the result of genetic manifestative inhibition about the human mast cell-1(HMC-1), Cimicifuga heracleifolia has considerable effect in IL-4 in IL-5, and Tussilage farfara L. has in IL-4. According to the above results, it is suggested that several Herb-Extract have anti-allergic effect.
