This study for developing a new anti-inflammatory medicine was sought by investigating the antiinflammatory properties of C. indicum L. extract. Rats were treated with either saline (control) or C. indicum L. extract and then injected with LPS. We found that the plasma concentration of IL-1${\beta}$ IL-6, TNF-${\alpha}$and IL-10 peaked at 5h after LPS injection, and the plasma concentration of IL-6 and TNF-${\alpha}$ showed a tendency to decrease, and IL-10 concentration showed a tendency to increase with increasing levels of C. indicum L. extract. In the liver concentration of cytokines at 5 h post LPS injection, IL-1${\alpha}$ and IL-6 decreased with increasing concentration of C. indicum L. extract, however TNF-${\alpha}$ and IL-10 did not differ significantly the treatment groups.

We examined the inhibitory activities against monoamine oxidase (MAO) of Chrysanthemum indicum L. in vitro and in vivo methods. Methanolic extract of C. indicum showed significant inhibitory activities on MAO-A that were prepared from rat brain in vitro. The inhibitory activities were measured by serotonin as a substrate. The $IC_{50}$ value of methanolic extract of C. indicum was 0.24 mg/ml for the inhibition of MAO-A. The ethylacetate fraction of methanolic extract of C. indicum exhibited the best activity toward MAO-A with $IC_{50}$ value of 0.05 mg/ml in vitro. It was observed that those activities in vivo tests have different tendency each other. Ethanolic extract of C. indicum was have no effect on rat MAO by the oral administration (p<0.05). However, MAO inhibitory activities of ethanolic extract of C. indicum by the oral administration have similar tendency to those of iproniazid. Consequently, we suggest that C. indicum may have the effects on the inhibitory activities against MAO both in vitro and in vivo. These results indicates that the C. indicum extract has properties indicative of potential neuroprotective ability.

To fulfill the increasing demand for a high quality of flower, we investigated the effects of nitrogen application on plant growth, yield and bioactive compounds of Chrysanthemum indicum L.. C. indicum L. was cultivated in a pot scale, and nitrogen applied with the level of 0 (N0), 50 (N50), 100 (N100), 150 (N150), 200 (N200) and $300\;(N300)\;kg\;ha^{-1}$ to suggest optimum rate of nitrogen fertilization. Phosphate and potassium applied the same amount of $80-80\;kg\;ha^{-1}$ ($P_2O_5-K_2O$) in all treatments. Growth characteristics and yields of C. indicum L. were significantly affected by nitrogen application. Maximum yield achieved in 265 and $295\;kg\;ha^{-1}$ N treatment on the whole plant and the flower parts, respectively. The nitrogen content and uptake of whole plant significantly increased by the increase of nitrogen application. Five major components of essential oil, $\alpha$-pinene, 1,8-cineol, chrysanthenone, germacrene-D, and $\alpha$-curcumene in flowerheads of C. indicum L. occupied approximately 40% of peak area, germacrene-D decreased by the increase of nitrogen application among them. However, cumambrin A contents in the flower parts of C. indicum L. were affected negatively by the increase of nitrogen application, but total yields of cumambrin A in flower part significantly increased. Conclusively, nitrogen fertilization could increase the yield of flowerheads. The optimum application level of nitrogen fertilizer might be on the range of $265-295\;kg\;ha^{-1}$ in a mountainous soil.

In recent years, research into medicinal herbs with antioxidative activities has increased. Chrysanthemum morifolium and Chrysanthemum indicum are aromatic herb plants and that have long been used in traditional Vietnamese medicine. This study aims to evaluate the chemical compositions and antioxidative activities of essential oils hydrodistilled from the flower heads of C. morifolium and C. indicum. The chemical compositions of the essential oils were compared using gas chromatography/mass spectrometry (GC/MS) analysis. The antioxidative activity was determined and evaluated spectroscopically by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, metal chelating activity, reducing power, and total antioxidant capacity assays. According to the GC/MS results, chrysanthenone was predominant in the essential oils of both C. morifolium (64.14%) and C. indicum (32.02%). This is the first report of the identification of chrysanthenone as a major constituent of the essential oil of C. morifolium. Both Chrysanthemum oils were also revealed to possess antioxidant potential, exhibiting high antioxidative activities. In particular, the DPPH radical scavenging activities of the C. morifolium and C. indicum oils at a concentration of 100 mg/mL were 76.9 and 83.2%, respectively. The metal chelating values of C. morifolium and C. indicum were 0.85 and 0.76, whereas the reducing power values of that at 100 mg/mL were 0.76 and 0.71, respectively. This study provides the chemical properties of the essential oils of both C. morifolium and C. indicum grown in Vietnam and their potential antioxidant capacity.

Chrysanthemum indicum is widely used to treat immune-related and infectious disorders in East Asia. C. indicum flower oil contains 1,8-cineole, germacrene D, camphor, ${\alpha}$-cadinol, camphene, pinocarvone, ${\beta}$-caryophyllene, 3-cyclohexen- 1-ol, and ${\gamma}$-curcumene. We evaluated the safety of C. indicum flower oil by conducting acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation tests. Mortality, clinical signs and gross findings of mice were measured for 15 days after the oral single gavage administration of C. indicum flower oil. There were no mortality and clinical signs of toxicity at 2,000 mg/kg body weight/day of C. indicum flower oil throughout the 15 day period. Micronucleated erythrocyte cell counts for all treated groups were not significantly different between test and control groups. Levels of 15.63~500 ${\mu}g$ C. indicum flower oil/plate did not induce mutagenicity in S. Typhimurium and E. coli, with or without the introduction of a metabolic activation system. These results indicate that ingesting C. indicum flower oil produces no acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation.

Chrysanthemum indicum (Asteraceae) is a perennial plant belonging to the genus Chrysanthemum. The basic chromosome number of Chrysanthemum sensu stricto is x = 9, and it consists of a series of polyploids ranging from diploid to decaploid. However, C. indicum, which occurs in Korea, is known to consist of only tetraploids, except for two diploid populations that are sympatric with C. zawadskii and C. boreale. During the collection of plant materials as part of a study to ascertain the diversity of Chrysanthemum in Korea, we found new diploid populations (2n = 18) of C. indicum in the southern region of Korea and describe them here in detail.

This study investigated the effects of addition of Chrysanthemum indicum L. extracts on quality characteristics of Kukhwju during fermentation. Fermented liquors without C. indicum L. were used as the control group. For experimental groups, we added 1, 2, 5, and 10% C. indicum L. extracts and brewed according to the addition method written in Yorok. The pH level during fermentation phase, alcohol concentration, level of reducing sugars, and acidity were measured in each of the experimental groups. After fermentation, we measured total contents of phenols, antioxidant effects, free sugars, organic acids, and chromaticity. During fermentation, no significant difference was observed between the C. indicum L. group and control group. Regarding total phenol contents and antioxidant effects, only the 5% and 10% C. indicum L. groups showed higher contents of phenols than the non-addition group. In general, 5% and 10% C. indicum L. addition groups were positively evaluated. In conclusion, Kukhwaju with 10% C. indicum L. extract showed the best antioxidant effects. In the present study, we obtained different characteristics and determined the optimum addition amount of C. indicum L.

The present study investigated the antitumor activity of the aqueous-alcoholic extracts from unripe cotton balls of Gossypium indicum. An Exposure of murine B16 melanoma and L1210 lymphoma cells to the extracts resulted in their severe deaths in time- and concentration-dependent manners. Of the extracts, hydrophilic fractions were most efficacious for the antitumor activity and found to contain certain amounts of catechin and its derivatives. The hydrophilic extract fraction C36B2-8 had approximately 10 times more cytotoxic effects on B12 and L1210 cells than on isolated murine thymocytes. High concentrations (>150 $\mu$g/ml) of C 36B3-8 mainly induced necrotic cell death. At low concentrations (<100 $\mu$g/ml), however, C 36B3-8 induced not only necrosis but also apoptosis of the two tumor cell lines, which was proved by the TUNEL staining and DNA fragmentation techniques. The data indicate that certain ingredients of the cotton ball extract of G. indicum have an antitumor activity.

Chrysanthemum indicum L. (Gamgug) has been examined to study their flowering habits, yields and bioactive compounds under different planting densities and mowing dates. The planting density experiment revealed a significantly increasing stem diameter, number of flowers and branches with decreasing plant density in the $100\;cm{\times}30\;cm$ and $130\;cm{\times}30\;cm$ treatments as compared to $70\;cm{\times}30\;cm$ treatments, but not plant height, leaf and flower width. On the other hand, the mowing date experiment showed that growth characteristics of plants were similar to the control plants (not mowing) and June 20 treatment, but July 20 treatments had significantly smaller than the control. The weights (g $plant^{-1}$) of dry flowers were affected by the planting density and mowing date. The flower yield of $586\;kg\;ha^{-1}$ obtained at $100\;cm{\times}30\;cm$ density was 11% and 22% higher than that of $120\;cm{\times}30\;cm$ and $70\;cm{\times}30\;cm$ treatments, respectively. The yield of dry flowers in the control and June 20 mowing date ranged $495-508\;kg\;ha^{-1}$, which is 40-42% higher than the yield in the July 20 treatments. The amount of essential oil (g $plant^{-1}$) in medically valuable flowerheads of C. indicum L. was statistically different between mowing dates but not among planting densities. The study showed that planting density and the mowing date could increase yields of flowerheads. An optimum planting density of $100\;cm{\times}30\;cm$ and mowing date of on or before June 20 is recommended for C. indicum L.
