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.

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.

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.

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 (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.

Gochujang samples with essential oils were evaluated for sensory including taste and, smell during various storage periods with the aim of developing improved high value-added products. The sensory testing was performed on Gochujang with 0.005% Zanthoxylum piperitum and Chrysanthemum indicum essential oils, extracted through steam distillation. During storage at 4 and $20^{\circ}C$ for 8 weeks, sensory testing was performed at 0, 1, 2, 4 and 8 weeks by trained panelists. Overall quality decreased in Gochujang samples containing Z.piperitum essential oil and increased in samples containing C.indicum essential oil, at 4 and $20^{\circ}C$. Samples stored at $4^{\circ}C$ were quality more then those stored at $20^{\circ}C$. Sensory evaluation was highest for Gochujang with C.indicum essential oil stored at $4^{\circ}C$. It is concluded that functional Gochujang can be developed by adding small quantities of essential oils. Increasing the amount of essential oil added is likely to affect the innate taste and flavor of Gochujang.

The composition of essential oils from Chrysanthemum zawadskii var. latilobum and C. indicum were analyzed and compared. The results of gas chromatography-mass spectrometry revealed there were distinctly different compositional patterns between C. zawadskii var. latilobum and C. indicum essential oils. The combinatorial effect of the oil of C. zawadskii var. latilobum and C. indicum, with various antibiotics was assessed against antibiotic-susceptible and -resistant strains of Staphylococcus aureus and Streptococcus pneumoniae. The essential oil fraction significantly inhibited most of the tested antibiotic-susceptible and -resistant strains of S. pneumoniae, with minimum inhibiting concentrations (MICs) ranging from 0.5 to 4.0 mg/ml. The fractional inhibiting concentration indices (FICIs) of the oils when combined with antibiotics against S. aureus and S. pneumoniae ranged from 0.26 to 0.75, and showed synergistic or additive effects.

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.

Purpose: Breastfeeding is the optimal method for feeding a newborn. But insufficient breast milk is the major reason why mothers give up breastfeeding. Herbal galactagogues have been used increasingly to treat postpartum hypogalactia. This study examined the effect of an herbal tea containing Chrysanthemum indicum, as the main ingredient, on milk production in lactating rats. Methods: The herbal tea contained C. indicum (27%), Foeniculum vulgare Mill (21%), Pimpinella anisum (18.2%), Carum carvi (16.1%), Urtica dioica (14.7%), and Gardenia jasminoides (3%). Sixteen lactating Sprague-Dawley (SD) rats were divided randomly into 2 groups, the normal control group (NC; n = 8), and the galactagogue herbal tea group (GHT; n = 8) for 7 days. Lactating rats were administered the decoction of an herbal galactagogue mixture by oral gavage or the same amount of distilled water and milk production was assessed by measuring the pups' weights during the suckling period. The blood concentrations of prolactin, cortisol, oxytocin levels and mammary gland tissues were examined to assess the effects of the galactagogue. Results: Milk production was 9.2% higher in the GHT group given the herbal tea than in the NC group and the difference was statistically significant. The cortisol level in the GHT group was 17.2% higher than the NC group. The herbal tea containing C. indicum increased the size of the alveoli epithelium cells and the mammary lobe. Conclusion: The present study revealed the potential of herbal tea containing C. indicum to enhance milk production in postpartum SD rats.
