Chrysanthemum indicum L. (Asteraceae) is a common traditional herbal medicine used for the treatment of inflammation, hypertension, and respiratory diseases due to its strong antagonistic function against inflammatory cytokines. In this study, the effects of Chrysanthemum indicum L. extract (CIE) on the function of osteoblastic MC3T3-E1 cells and the production of local factors in osteoblasts were investigated. CIE (100 ${\mu}g/mL$) significantly increased the growth of MC3T3-E1 cells and caused a significant elevation of alkaline phosphatase (ALP) activity, and the deposition of collagen and calcium in the cells (p<0.05). The effect of CIE in increasing cell growth, ALP activity, and collagen content was completely prevented by the presence of 1 ${\mu}M$ tamoxifen, suggesting that CIE's effect might be partly involved in estrogen-related activities. These results indicate that the enhancement of osteoblast functionality by CIE may prevent osteoporosis and inflammatory bone diseases.

Alzheimer's disease (AD) is the most common neurodegenerative disorder and is responsible for more than 50% of all dementia cases. There is significant interest in finding new sources of compounds that inhibit acetylcholinesterase (AChE) to be used in the treatment of AD, since only a few AChE inhibitors, such as galanthamine, physostigmine, and tacrine, are available for clinical use. In the present study, ICR mice were treated with a 1 mg/kg scopolamine, which caused impaired cognitive ability. The steady consumption of a water extract of Chrysanthemum indicum Linne flowers for 3 months significantly prevented the scopolamine induced deficit of the spatial cognitive capability of mice. It also improved long-term memory in mice with amnesia induced by scopolamine, as assessed by the Morris water maze and passive avoidance tests. In addition, water extract consumption significantly decreased AChE activity in mouse brain, leading to inhibition of acetylcholine hydrolysis.

There is significant interest in finding new sources of acetylcholinesterase (AChE) inhibitors for use in treating Alzheimer's disease, since only a few AChE inhibitors are available for clinical use, such as galanthamine, physostigmine, and tacrine. The ethanol extract of Chrysanthemum indicum Linne flowers was analyzed and found to markedly decrease AChE activity. Acaciin and $acacetin-7-O-{\beta}-D-galactopyranoside$ were identified as the active compounds responsible for the AChE inhibition by using an activity-guided fractionation strategy. The relationship between structure and activity for five flavonoids (acaciin, $acacetin-7-O-{\beta}-D-galactopyranoside$, luteolin, and two other commercially available flavonoids, i.e., apigenin and acacetin) was also investigated, revealing that the presence of methoxy groups at C-4' in the B ring and a sugar at O-7 in ring A appear to be essential for the inhibition of AChE.

Leaf gall was occurred on Rhododendron indicum(L.) Sweet[=Azalea indica L.] in a farmer's garden located in Geumsan-myon, and along the walk way of Gangju pond in Jeongchon-myon, Jinju, Korea. The infected leaves was deformed into very conspicuous, pale, fleshy shapeless galls. Basidia were fusiform, $3{\sim}5$ sterigma, and $8{\sim}35{\times}3{\sim}6{\mu}m$ in size. Basidiospores were musiform, straight or curved and $10{\sim}22{\times}3{\sim}5{\mu}m$ in size. The causal organism was identified as Exobasidium japonicum Shirai based on the mycological characteristics of the fungus and pathogenicity. This is the first report on the leaf gall of R. indicum caused by E. japonicum in Korea.

Chrysanthemum indicum L. (Asteraceae) is a traditional herbal medicine that has been used for the treatment of inflammation, hypertension, and respiratory diseases due to its strong antagonistic activity against inflammatory cytokines. The effects of Chrysanthemum indicum L. Extract (CIE) for increasing cell growth, alkaline phosphatase (ALP) activity, and collagen content were totally inhibited, suggesting that the effect of CIE might be partly involved with estrogen activity. Furthermore, the protective effects of CIE on the response of osteoblasts to oxidative stress were evaluated. Osteoblastic MC3T3-E1 cells were incubated with hydrogen peroxide and/or CIE, and markers of osteoblast function and oxidative damage were examined. CIE significantly increased cell survival, ALP activity, and calcium deposition, and decreased the production of Reactive Oxygen Species (ROS) and Tumor Necrosis Factor-${\alpha}$ (TNF-${\alpha}$) in osteoblasts. Taken together, these results indicate that the enhancement of osteoblast function by CIE may prevent osteoporosis and inflammatory bone diseases.

In the present study, antioxidant and anti-inflammatory activities were measured in Chrysanthemum indicum Linne extracted with different ethanol concentrations. The 50% ethanol extract demonstrated the highest yield of 33.6%, while the 30% and 70% ethanol extracts showed the highest total polyphenol contents of 59.70 and 61.35 mg GAE/g, respectively. The antioxidant activity of 70% ethanol extract was highest in the DPPH radical scavenging activity (RC₅₀ 14.95 ㎍/mL) and ABTS⁺ radical scavenging activity (RC₅₀ 42.28 ㎍/mL). FRAP activity was significantly higher in the 30% ethanol extract than the other extracts. The anti-inflammatory effects of Chrysanthemum indicum Linne extracted with different ethanol concentrations were examined using nitric oxide (NO) inhibition assays. In LPS-induced RAW 264.7 cells, the 30% ethanol extract showed the highest inhibition of NO production with 11.16 µM at a concentration of 200 ㎍/mL. The results of this study suggest that Chrysanthemum indicum extracted 30% or 70% ethanol concentrations as potential functional raw material.

In this study, the extracted phenolic compounds from 98 species of oriental herbal medicine were examined for biological activities to be used as functional resources. In particular, the anti-gout effect by xanthine oxidase (XOase) inhibition was determined using water and ethanol as extraction solvents because of their non-toxicity in the human body. The extracts of Chrysanthemum indicum L. (83.45%), Cuscuta chinensis (60.22%), Asiasarum sieboldi F. Maekawa (51.66%), Acorus gramineus (67.8%), Aconitum pseudo-laeve var. erectum (75.23%), Thuja orientalis (47.27%), Polygonum aviculare (53.98%), Carthami semen (63.99%), and Syzygium aromaticum (40.22%) showed relatively high XOase inhibitory activity. Chrysanthemum indicum L. was selected for its high XOase inhibitory activity. The biological compounds in Chrysanthemum indicum L. were identified to contain phenolics included in extracts of solids. Ultra-fine grind technology showed a higher extraction yield than normal grind and fine grind technology. Ethanol extracts showed relatively higher XOase inhibitory activity than water extracts. XOase inhibitory activity increased in a dependent manner as phenolic concentration increased. Therefore, ultra-fine grind technology was confirmed for use in increasing the extraction yield of XOase inhibitory compounds from Chrysanthemum indicum L.. Extracts from Chrysanthemum indicum L. are expected to be a useful functional resource for the prevention or treatment of gout.

Anti-inflammatory and anti-oxidative activities were examined on the extract of Dendranthema indicum (D. indicum) flowers. The flowers were extracted two times for 24 h each with 70% ethanol. Upon the biological activities screening, the ethanol extract exhibited potent free radical scavenging activities and inhibited the production of nitric oxide on LPS-induced RAW264.7 macrophages effectively without causing cell toxicity. Further purification by medium pressure liquid hromatography (MPLC) and identification of the isolates led to identification of cynaroside (1) and apigetrin (2). The chemical structures of the isolated compounds were elucidated based on spectroscopic data including nuclear magnetic resonance (NMR) spectra, as well as comparison of the data to the literature values. Also, the quantitative analysis of the compounds was perfromed by high-performance liquid chromatography (HPLC). The isolates 1 and 2 were determined to inhibite the nitric oxide (NO) production dose-dependently. Based on these results, it was suggested that D. indicum extract could be useful as anti-inflammatory agents in cosmetics applications.

This study shows the dyeability and antibacterial activity about cotton and silk fabrics dyed with Chrysanthem indicum L. In the case of dyeability, in the first, K/S value was shown comparatively high numerical value. The value of all test sample was over 20. In the next, in the case of colorfastness, the light colorfastness showed the lowest grade, the other colorfastness was relatively good. However there are some differences according to fabrics and mordants. In the case of antibacterial activity to Klebsielia pneumoniae, the cotton fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted $CuSO_4$.$5H_2O$, and the silk fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted $CuSO_4$.$5H_2O$.$Al_2$ and $(SO_4)_3$.
