The monoterpenes and sesquiterpenes are analysed in the leaf and stem of Chrysanthemum boreale using gas chromaltography-mass spectrometry (GC-MS). The total amount of sesquiterpenes are always higher than monoterpenes in both leaf (2.0-3.4 times) and stem (1.6-8.3 times). The mono- and sesquiterpenes yields of the leaf are higher than the stem. There was no significant difference among the leaf developmental stages, while those of stem were varied. Seventeen monoterpenes and 9 sesquiterpenes compound in this plants comprised more than 5% of the mean total monoterpenes and the total sesquiterpenes in each dates. Among leaf monoterpenes, the concentration of (+)-Limonene and unknown compound no. 13 (Retention time, R.T.=17.28) varied significantly during leaf growing season, and the concentrafion of unknown compound no. 7 (R.T.=35.04) and no. 9(R.T.=35.71) varied in the leaf sesquiterpenes. Similarly the results from the leaf, the concentration of five monoterpenes in stem also varied significantly during maturing period, and much varied in seven compounds of stem sesquiterpene. The major sesquiterpenes of leaf and stem were ${\alpha}-Humulene$ and compound no. 2(R.T.=26.19).

Korean folk medicine 'DulGugWha' has been used to cure common cold, cough and chronic and acute gastiritis in Korea. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of 'DulGugWha', the morphological and anatomical characteristics of Chrysanthemum species growing in Korea, i.e. C. boreale, C. indicum, C. zawadskii and C. zawadskii var. latilobum were studied. As a result, 'DulGugWha' was proved to be the whole plant body of Chrysanthemum boreale of Compositae.

The volatile aroma constituents of Chrysanthemum zawadskii var. latilobum K. were separated by hydro distillation extraction (HDE) method using a Clevenger-type apparatus, and analyzed by gas chromatography-mass spectrometry (GC/MS). The yield of C. zawadskii var. latilobum K. flower essential oil (FEO) was 0.12% (w/w) and the color was light green. Fifty-five volatile chemical components, which make up 88.38% of the total aroma composition, were tentatively characterized. C. zawadskii var. latilobum K. FEOs contained 27 hydrocarbons, 12 alcohols, 7 ketones, 4 esters, 1 aldehyde, 1 amine, and 3 miscellaneous components. The major functional groups were terpene alcohol and ketone. Borneol (12.96), (${\pm}$)-7-epi-amiteol (12.60), and camphor (10.54%) were the predominant volatiles. These compounds can be used in food and pharmaceutical industries due to their active bio-functional properties.

Chrysanthemum morifolium (CM) is a herb widely used in medicine for the treatment of a variety of diseases. In this study, using mouse peritoneal macrophages, we have examined whether CM affects nitric oxide (NO), tumor necrosis factor $(TNF)-\alpha$ and interleukin (IL)-6 induced interferon $(IFN)-\gamma$ and lipopolysaccharide (LPS). CM inhibits $IFN-\gamma$ and LPS-induced NO in dose dependent manner. We also found that CM inhibits pro-inflammatory cytokine, $TNF-\alpha$ and IL-6. The expression of cyclooxygenase-2 was reduced by CM. These finding means that CM can be used in controlling macrophages-mediated inflammatory disease.

Nine sesquiterpene lactones, which were isolated from Hemisteptia lyrata Bunge. Chrysanthemum zawadskii Herbich var. latilobum Kitamura and Chrysanthemum boreale Makino were evaluated for the farnesyl-protein transferase (FPTase) inhibitor, conducted by the scintillation proximity assay (SPA). The angeloylcumambrin B and tigloylcumambrin B inhibited a recombinant rat FPTase with $IC_{50}$ value of $78\;{\mu}g/ml$ $(225\;{\mu}M)$ and $90\;{\mu}g/ml$ $(260 \;{\mu}M)$, respectively.

Cumambrin A has been isolated from the dried flowers of Chrysanthemum boreale Makino. The complete $^1H$ and $^{13}C$ NMR assignment of cumambrin A was achieved from two-dimensional $^1H$-$^1H$ COSY and $^{13}C$-$^1H$ COSY spectra with the aid of homonuclear and heteronuclear double resonance experiments. The its structure has been verified by single crystal X-ray diffraction.

Volatile flavor compounds were isolated from the flowers of Chrysanthemum indicum L. (gamguk) produced in Korea and China by the hydro distillation, and were analyzed by gas chromatography-mass spectrometry (GC/MS). The yield of oils from Korean and Chinese gamguk were 2.0 and 0.5%(v/w), respectively. Sixty-three volatile compounds of Korean gamguk representing 89.28% of the total peak area were tentatively identified, including 35 hydrocarbons, 12 alcohols, 6 ketones, 3 esters, 5 aldehydes, 1 oxide, and 1 miscellaneous component. Thirty-six volatile components of Chinese gamguk constituted 58.15% of the total volatile composition were tentatively characterized, consisting of 19 hydrocarbons, 7 alcohols, 2 ketones, 2 esters, 4 aldehydes, 1 oxide, and 1 miscellaneous component. The predominant components of Korean oil were ${\alpha}$-pinene, 1,8-cineol, and chrysanthenone. Whereas, camphor, ${\alpha}$-curcumene, and ${\beta}$-sesquiphellandrene were the main aroma compounds of Chinese gamguk.

The flowers of Chrysanthemum boreale afforded handelin, a unique guaianolide dimer and a mixture of n-hydrocarbons and n-hydrocarbon alcohols in addition to b-sitosterol and b-sitosterol glucoside. Detailed analysis of the $^{1}H$- and $^{13}C$-NMR spectra of handelin was carried out by the application of two-dimensional $^{1}H-^{1}H$-COSY and $^{1}H$- $^{13}C$ multiple-bond, multiple-quantum spectroscopic correlation techniques. Handelin was inactive in the in vitro anti-tumor activity.

In order to study the residual amounts of absorbed organochlorine pasticides in vegetables, heptachlor and endrin were sprayed 2,4 and 6kg per 10a., respectively, before sowing the seeds in the station. The experiemental study is primarily concerned with the absorption in lettuce nad garland chrysanthemum. The absorption of each pesticide into lettuce and garland chrysanthemum, and residual pesticides in soil by timne have been analyzed by the gas chromtographic method, and the ratio of residual pesticides in vegetablesand soil were estimated. Heptachlor, heptachlor epoxide and endrin in lettuce nad garland chrysanthemum at the market in Seoul area hvae also analyzed and found extremely low level of pesticides in comparison with the level in above experimental vegetables as well as same vegetables in Japan.

Fourteen kinds of medicinal plants were screened for determining inhibitory activities on monoamine oxidase B. The extracts of Artemisia Messer-Schmidtiana (herba), Chrysanthemum indicum(flos), Ericibe obtusifolia (radix et rhizoma) and Sophora japonica (flos) strongly inhibited the enzyme. Among them, Chrysanthemi flos was chosen for elucidating its active principles, and some flavonoids were isolated and identified as acasetin (I), 5, 7-dihydroxy chromone (II), diosmetin (III), apigenin (IV), eriodictyol (V) and luteolin (VI).$IC_{50} were determined as following: 1, 2.46;II, 0.19; III, 2. 11mM, and the others showed weak inhibition.
