Chemical compositions of petals of Chrysanthemum spp. were determined to renew its interest as a food material. The moisture contents of wild Chrysanthemum boreale and holticulturized Chrysanthemum morifolium were 11.7% and 11.0%. The proximate chemical ompositions were 6.1% and 11.7% in protein, 3.7% and 5.2% in ash, 11.1% and 12.8% in reducing sugar, of C. boreale and C. morifolium, respectively. Free sugars were mainly composed of fructose, glucose and sucrose. In fatty acid composition, the ratios of saturated to unsaturated fatty acids were 1.2:1 and 3.0:1, respectively. The amino acids determined were found 0.18 and 0.26 in the ratio of essential to total amino acids in each sample. Major elements of Chrysanthemum petals were Ca, K, Fe, Mg and Na, but the contents of Ca and Fe were more than twice higher in C. boreale than c. morifolium, Major volatile flavor components were 28.22% of epi-bicyclophellandrene and 24.55% of camphor in C. boreale, and 14.24% of 4-methyl-1-(10methylethyl)-3-cyclhexen-1-ol, 10.74% of camphor and 7.64% of 1,8-cineol in C. morifolium.

Two sesquiterpene lactones were isolated from the flowers of Chrysanthemum boreale Makino by the silica gel column chromatography and recrystallization. On the basis of spectrometric studies including $^1H-NMR,\;^{13}C-NMR,\;DEPT,\;^1H-^1H\;COSY,\;{13}C-^1H\;COSY$, IR and Mass, compounds 1 and 2 were identified as germacranolide, tulipinolide and costunolide, respectively. And they showed antibacterial activity against Vibrio parahaemolyticus, Bacillus subtilis, Bacillus cereus and Staphylococcus aureus. This is the first report that Chrysanthemum boreale contained tulipinolide and costunolide.

Chrysanthemum boreale Makino is widely distributed in Korea, China, Japan and Southeast Asian countries. C. boreale is one of the herbs used for treating various inflammatory diseases in oriental medicine. The present study was conducted to identify biologically active compounds from the leaves and stems of C. boreale. We isolated two sesquiterpene sactones from the leaves and stems of C. boreale using silica gel column chromatography and recyclic high perfomance liquid chromatography. The lactones were characterized by their spectroscopic data (NMR, IR, MASS). These compounds were subjected to Farnesyl Protein Transferase (FPTase) inhibition, Nitric Oxide (NO) release inhibition and apoptosis inhibition. The structur of the following isolated compound were elucidated 8,10-${\small{O}$-Acetyl-2-methoxy-10-hydroxy-3,11(13)-guaiadiene-12,6-olide and 4,10-dihydroxy-8-${\small{O}$-Acetyl-2,11(13)-guaiadiene-12,6-olide. In the NO release inhibition assay, compound 2 showed strong activities, with an $IC_{50}$ value of $7{\mu}g/mL$, whereas compound 1 did not exhibit significant activity with an $IC_{50}$ value of over $14{\mu}g/mL$ against murine macrophage.

Objectives : Chrysanthemum boreale flower is widely distributed in Korea, Japan, China, and Eastern countries. C. boreale flower is also one of the herbs used for the treatment of various inflammatory disease in Korean Medicine. So, this research was designed to study anti-inflammatory effect of C. boreale flower and its mechanism. Methods : We investigated nitro oxide (NO) and prostaglandin $E_2$ ($PGE_2$) production by ELISA. And expressions of inducible nitric oxide synthase (iNOS), Cyclooxygenase-2 (COX-2) and nuclear factor-${\kappa}B$ P50/65 (NF-${\kappa}B$ P50, NF-${\kappa}B$ P65) were measured in RAW 264.7 murine macrophage cells induced by LPS. Results : MeOH ex., EtOAc fr., $CHCl_3$ fr. and Water fr. of C. boreale flower showed anti-inflammatory effect through inhibition of NO and PGE expression respectively. Among them, EtOAc fr. and $CHCl_3$ fr. inhibited production of NO and $PGE_2$ through inhibition of iNOS and COX-2 expression. And MeOH ex., EtOAc fr. and $CHCl_3$ fr. inhibited translocation of NF-${\kappa}B$ P65, NF-${\kappa}B$ P50 by inhibiting phosphrylation of $I{\kappa}B$. Conclusions : MeOH ex. EtOAc fr, $CHCl_3$ fr., and Water fr. of the C. boreale flower have anti-inflammatory activity.

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).

The effect of the essential oil obtained from Chrysanthemum boreale Makino on the apoptosis of KB cells was investigated. Cytotoxicity and cellular DNA content were analyzed by MTT assay, flow cytometry, agarose gel electrophoresis, and Hoechst 33258 staining. The caspase-3 and poly (ADP-ribose) polymerase (PARP) proteins were estimated by Western blotting method. The various cytotoxic effects of the essential oil which are hallmarks of apoptosis, including DNA fragmentation, apoptotic body formation, and sub-G1 DNA content, all progressed in a dose-dependent manner. Treatment with an apoptosis-inducing concentration of the essential oil caused rapid and transient induction of caspase 3 activity. Further, the efficacious induction of PARP cleavage and caspase-3 activation was observed at an essential oil concentration of 0.1 and 0.2 mg/mL for 12 hr.

Chrysanthemum boreale Makino (C. boreale) is widely distributed in Asian countries, and has traditionally been used to treat various inflammatory diseases including bronchitis. In this study, we aimed to isolate biologically active compounds from leaves and stems of C. boreale. Chemical components were purified by column chromatograpy and recyclic HPLC, and characterized from their spectral data (IR, MS, NMR). Biological activity experiments were conducted for Farnesyl-protein transferase (FPTase) activity, apoptosis and nitirc oxide (NO) release. As a results, three sesquiterpene lactones were isolated. Compound 1 (4-methoxy-8-O-acetyl-10-hydroxy-2,11(13)-guaiadiene-12,6-olide) showed strong cytotoxic activities having an average growth inhibition of 50% ($GI_{50}$) value of $1.89{\mu}g/m{\ell}$ against human colon adenocarcinoma cells. Compound 1 also showed a low half maximal inhibitory concentration ($IC_{50}$) value of $10{\mu}g/m{\ell}$ for NO release. In the caspase 3 activity, compound 1 and compound 2 (8-O-(2-carbonyl-2-butyl)-3,10-dihydroxy-4,11(13) -guaiadiene-12,6-olide) exhibited 94% and 90% apoptosis inhibition activity, respectively. Compound 3 (4,8-O-diacetyl -10-hydroxy-2(3),11(13)-guaiadiene-12,6-olide) showed a strong inhibitory effect on FPTase activity with 90% inhibitory activity at a concentration of $100{\mu}g/m{\ell}$. These results clearly show the presence of lactone compounds in the leaves and stems, which may partially contribute to the pharmacological activity of C. boreale.
