  • 국화과(Compositae) 다년생 초본인 산국속(Dendranthema)은 국내 약 13여종이 자생하는 것으로 알려져 있으며, 이 중 감국(D. indicum (L.) Des Moul.)과 산국(D. boreale (Makino) Ling ex Kitam.), 구절초(D. zawadskii var. latilobum (Maxim.) Kitam.)가 주로 차 또는 한약재 등의 원료로 이용되고 있다. 차로 이용되는 꽃은 산국이 감국에 비해 상대적으로 작아서 구분이 가능하지만 시중에는 건조된 형태로 가공 유통되므로 육안으로 구분이 쉽지 않고, 산국 유래 제품들은 국내에서 감국 또는 국화로 혼용해서 표기되어 유통되고 있어 그 기원을 명확히 정립할 필요가 있다. 이에 본 연구는 감국과 산국의 분자유전학적 판별을 위해 DNA 바코드 후보 유전자를 활용하여 염기서열분석으로 확보된 SNP 및 InDel 정보를 바탕으로 CAPS 마커를 개발하고자 수행되었다. 감국과 산국 모두 trnL-trnF intergenic spacer 구간에서 약 1kb의 PCR 산물이 확인되었고, 이들 염기서열에서 분석한 2 SNP 및 3 InDel을 대상으로 CAPS 마커 개발을 위한 제한효소 사이트를 탐색하였다. Gap을 포함한 774bp (감국/산국=A/G) 위치의 SNP에서 BstUI(GC^GC)처리로 CAPS 마커로 전환 가능함이 확인되었고, 이에 감국과 산국의 PCR 산물에 제한효소를 처리한 결과, 제한효소 인식 사이트가 존재하는 산국에서 두 개의 DNA 단편이 확인되었다. 위 결과는 다양한 형태로 가공 유통되는 감국과 산국의 판별을 위한 마커로 활용될 수 있으며, 본 연구에 활용된 기술은 추후 건강기능식품 개발을 위한 원료표준화 확립 연구에 유용할 것으로 판단된다.

  • This study investigated the chemical composition of four Korean cultivated Chrysanthemum indicum L. (Gamguk 1 ho, Gamguk 2 ho, Gamguk 3 ho, and Wonhyang) which are used in the food and fragrance industries to identify their volatile flavor compounds. These compounds were analyzed using headspace GC-MS from plant samples cultivated in the same region of Korea (Sancheong-gun, Gyeongsangnam-do). A total of 23 compounds were identified, eight of which were common across the four cultivars. The major flavor components in the three Gamguk plants were identified as 3-carene, camphene, ${\beta}$-phellandrene, eucalyptol and (+)-camphor. Eleven compounds, including (+)-camphor at 31.40%, were identified in Gamguk 1 ho. Gamguk 2 ho was found to contain 12 flavor compounds, predominant of which was camphene at 25.60%. Thirteen compounds including (+)-camphor (26.88%) were identified in Gamguk 3 ho, while 17 were detected in the Wonhyang cultivar, including trans-piperitol (47.33%), sabinene, and ${\gamma}$-terpinyl acetate. These results indicate differences in the type and ratio of functional volatile flavor ingredients in Chrysanthemum indicum L. cultivars which is highly valuable as material for fragrance product development.

  • In this study, we describe the inhibition of adipocyte differentiation by the lactic acid bacteria (LAB) fermentation product of Chrysanthemum indicum L. (CI) extract to control obesity. Preparation of LAB-fermented products was performed to overcome the cytotoxicity of CI extract. During fermentation and 3T3-L1 cell line experiment, cytotoxicity was not induced in the CI fermentation products over 1 day in culture. Fermented materials from highly proliferative cultures were selected for treatment of 3T3-L1 cells and for comparison with unfermented control groups. Cell survival and undifferentiated cell populations were decreased differentiation population in all experimental groups compared with controls, as measured using fluorescence-activated cell sorting analysis. Akt pathway activity increased upon treatment with these fermented extracts in 3T3-L1 cells. Gli2 depleted at the protein level in association with adipocyte differentiation. LAB KCTC 3115- and 3109-fermented extract treatment caused controlled Gli2 protein accumulation. Moreover, KCTC 3115 and 3109 were found to reduce C/EBPα and FAS was depleted, whereas pACC was increased at the protein level upon treatment with the fermentation products of each of the four LAB used in this study. With Lactococcus lactis subsp. lactis KCTC 3115 fermentation, the regulation of adipose differentiation and hedgehog signaling were also suppressed, thereby inhibiting the differentiation of progenitor cells. The basis for the activation of hedgehog signaling may provide insights into the treatment of obesity and the inhibition of adipocyte differentiation.

  • This study aimed to identify the hepatoprotective effects of a fermented Chrysanthemum indicum L. water extract. The extraction yield, antioxidant activities (ABTS and DPPH), and content of luteolin and luteolin-7-glucoside were significantly higher in the fermented C. indicum L. water extract (FCI) than in the C. indicum L. water extract. Treatment with FCI (200 ㎍/mL) significantly reduced the activities of gamma(γ)-glutamyl transferase, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase in HepG2 cells treated with 3% ethanol. Furthermore, FCI did not affect the viability of the HepG2 cells. These results suggest that FCI can be useful for the development of an effective hepatoprotective agent.

  • 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.

  • 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.

  • In an acute toxicity test for Chrysanthemum indicum Linne, 0.5~10 g/kg of Chrysanthemum indicum Linne extracts were administered. Chrysanthemum indicum Linne did not produce acute toxicity even at high doses of 10 g/kg, making it a highly safe material. In the chronic toxicity test, oral administration of Chrysanthemum indicum Linne up to 2 g/kg was carried out for 13 weeks, showing liver non-toxicity. The gout inhibitory effect of Chrysanthemum indicum Linne extracts was measured by inflammatory cytokine expression and foot thickness after 24 h of monosodium urate crystal (MSU) oral administration when inflammatory cytokine production reached a maximum. The group administered 2~4 g/kg of Chrysanthemum indicum Linne extract showed an inhibitory effect on gout inflammation and edema, whereas the 10 g/kg administered group showed an increase in inflammation. Therefore, the moderate concentration of Chrysanthemum indicum Linne extract for gout inhibitory effect was under 4 g/kg. Chrysanthemum indicum Linne extract showed an anti-inflammatory effect on MSU as a relatively safe material at high capacity. These results indicate that Chrysanthemum indicum Linne extract is thought to be an excellent substance for gout prevention.

  • 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.

  • In this study, the biological activity of water and ethanol extracts from Chrysanthemum incidicum Linne by ultrafine grinding for functional food source are examined. The content of phenolic compounds from Chrysanthemum incidicum Linne were the highest when extracted for 6 hr with 70% ethanol. The extraction yield of water and ethanol extracts were $7.12{\pm}1.61$ mg/g and $7.51{\pm}2.14$ mg/g, respectively. With ultrafine grinding, water and ethanol extracts were $8.63{\pm}1.15$ mg/g and $9.33{\pm}1.35$ mg/g, respectively. In determining anti-oxidative activity of Chrysanthemum incidicum Linne extracts, DPPH of normal grinding extracts was 83.52% and ultrafine grinding was 92.37%. In ABTS radical cation decolorization, normal grinding, fine grinding, and ultrafine grinding extracts were 90% or higher. In antioxidant protection factor (PF), water and ethanol extracts of ultrafine grinding showed relatively high anti-oxidative activities of each 1.82 PF and 2.16 PF, respectively. The TBARS value of ultrafine grinding extracts were lower than normal grinding and fine grinding extracts. The inhibition activity on xanthin oxidase of Chrysanthemum incidicum Linne extracts was 67.53% in ultrafine grinded water extracts and 83.45% in ultrafine grinded ethanol extracts. Inhibition on xanthin oxidase of ethanol extracts showed a higher inhibition effect than water extracts, and ultrafine grinding was higher than normal grinding. In angiotensin converting enzyme inhibition activity, ultrafine grinding water extract was 24% or higher, and ethanol extract was 34% or higher. The elastase inhibition activity of ultrafine grinding extract was 25.56%, which was higher than 20.34% of fine grinding extracts. Water extracts did not show hyaluronidase inhibition activity but ethanol extracts showed 35% of hyaluronidase inhibition activity. The determining expression inhibition of iNOS and COX-2 protein in macrophage by Chrysanthemum incidicum Linne extracts with a Western blot analysis, iNOS and COX-2 protein expression inhibition by Chrysanthemum incidicum Linne ethanol extracts were 40% and 15%, respectively at 100 ${\mu}g/mL$ concentration. The inhibitory patterns of iNOS and COX-2 protein expression was concentration dependent. The result suggests that Chrysanthemum incidicum Linne extracts by ultrafine grinding may be more useful than normal grinding as potential sources due to anti-oxidation, angiotensin converting enzyme and xanthine oxidase inhibition, anti-inflammation effect.
