The herb, Chrysanthemum zawadskii var, latilobum commonly known as Gu-Jul-Cho in Korea, used in traditional medicine to treat pneumonia, bronchitis, cough, common cold, pharyngitis, bladder-related disorders, gastroenteric disorders, and hypertension. Linarin is the main active compound and the biological mechanisms of its activity are unclear. It is believed that effects of this herb may be exerted through the pluripotent effectors of linarin due to its ability to treat a variety of afflictions. In this study, the effects of linarin on the mouse macrophages cell line, RAW 264.7, were investigated. It was found that linarin could activate macrophages by producing cytokines. Monocytes and tissue macrophages produce at least two groups of protein mediators of inflammation, interleukin 1 (IL-1 ) and the tumor necrosis factor (TNF). Recent studies have shown that TNF and IL-1 modulate the inflammatory function of endothelial cells, leukocytes, and fibroblasts. $TNF-{\alpha}$ production by macrophages treated with linarin occured in a dose dependent manner However, IL-1 production was largely unaffected by this natural product. This study demonstrated the ability of linarin to activate macrophages both directly and indirectly. Linarin also affect both cytosine production and nitric oxide inhibition, in addition to the expression of some surface molecules. Nitric oxide (NO), derived from L-argin-ine, is produced by two forms(constitutive and inducible) of nitric oxide synthase (NOS). The NO produced in large amounts by inducible NOS is known to be responsible for the vasodilation and hypotension observed in septic shock. Linarin was found to inhibit NO production in the LPS-activated RAW 264.7 cells. Linarin may be a useful candidate as a new drug for treating endotoxemia and the inflammation accompanied by NO overproduction. The linarin-treated total Iymphocytes exhibited cytotoxicity in a dose dependent manner between $20{\;}{\mu}g/ml{\;}and{\;}40{\;}{\mu}g/ml$. These results suggest that linarin may function through macrophage activation.

This study was carried out to select proper species for early stage replantation in granite forest roads cut-slope. From one to fourteen year elapsed forest roads in eight regional areas of Gyeongsang-do and Jeolla-do, sample plots were selected, and their vegetations and environmental factors were investigated. Soil organic matter, total nitrogen, soil moisture content, and bulk density in the granite weathering soils were below 0.4%, 0.03%, 12.4%, and above 1.2g/$cm^3$, respectively. The result indicated that the soil was not good for plant growth. The environmental factors affecting distribution of species in the granite forest roads were the elapsed year, elevation, and cut-slope aspect. Invaded species with high frequency in the forest road cut-slope ordered Pinus densiflora, Lespedeza bicolor, Rubus crataegifolius, Alnus hirsuta, Youngia denticulata, Patrinia villosa, Artemisia princeps var. orientalis, Zanthoxylum schinifolium, and Dactylis glomerata. Herbs seeded in earth stage such as Dactylis glomerata, Eragrostis curvula, Festuca arundinacea, Lespedeza sp., and Amorpha fruticosa had changed into perennial herbs and shrubs such as Youngia denticulata, Patrinia villosa, Aster scaber, Patrinia scabiosaefolia, Melica onoei, Astilbe chinensis var. davidii, Chrysanthemum zawadskii var. latilobum, Pueraria thunbergiana, Stephanandra incisa, and Clematis apiifolia, and had changed into plants such as Artemisia princeps var. orientalis, Artemisia keiskeana, Miscanthus sinensis, Pinus densiflora, Rhododendron mucronulatum, Rubus crataegifolius, and Zanthoxylum schinifolium according to elapsed year of forest roads. Leguma such as Lespedeza sp., Pueraria thunbergiana, Amorpha fruticosa, etc., herbs such as Artemisia keiskeana, Artemisia princeps var. orientalis, Chrysanthemum zawadskii var. latilobum, Miscanthus sinensis, etc., and woody plants such as Pinus densiflora, Rubus crataegifolius, Rhododendron mucronulatum, etc., with foreign herbs were considered as proper species for replantation in granite forest road cut-slope.

This study is carried out to find the most optimal soil-plant combination in the urban agriculture by analyzing the association of soil base material which is being used in the urban agriculture with the growth of plants. 4 types of easily purchased soil (bed soil(A), animal vermicast soil(B), earth worm soil(C) and matured compost(D)) verified in aspects of effect and safety of soil in terms of growth of crop is selected as experimental soil and B, C, D type soils are mixed with granite soil at the ratio of 7 : 3. And granite soil(E) is set as a controlled soil and is compared to verify the effect of the experimental mixed soil. Herbaceous plants are classified into the fruit vegetables (Lycopersicon esculentum Mill. and Capsicum annuum L.), leafy vegetables (Brassica campestris L. ssp. Pekinensis and Lactuca sativa L.), medicinal vegetables (Chrysanthemum zawadskii var. latilobum and Liriope platyphylla F. T. Wang & T. Tang). The results of comparison of growth of herbaceous plants in different soil types showed that fruit vegetables and leafy vegetables in general had excellent growth in D type soil mixture and A type soil in general and had the poorest growth in E type (controlled) soil. 'Chrysanthemum zawadskii var. latilobum' had the excellent growth in D type, B type, C type mixed soil and A type soil and E type (controlled) soil are followed in order. In the case of 'Liriope platyphylla F. T. Wang & T. Tang', the difference in growth by each soil was shown to be insignificant. Therefore, the soil applied in the urban agriculture varies depending on each species of herbaceous plants, but it is considered effective to cultivate herbaceous plant which is economical and productive by using D type mixed soil which can be recycled and inexpensive compared with other experimental soils in the urban agriculture.

본 연구는 야생화 초지조성을 위한 잔디형 목초 및 야생화초종의 선정과 혼파조합구성에 대한 기초자료를 탐색하고자 몇 가지 잔디형 목초와 야생화초종을 공시하여 초기생육, 경엽 및 근중, 건물수량, 개화특성 및 기호성 등을 비교분석하였다. 공시초종은 잔디형 목초 5종{Kentucky bluegrass(Midnight), tall fescue(Millennium), perennial ryegrass(Palmer III), redtop(Barricuda) 및 creeping bentgrass(Crenshaw)}과 야생화 11종{Chrysanthemum leucanthemum L., Coreopsis lanceolata L., Rudbeckia bicolor Nutt., Dianthus chinensis L., Chrysanthemum lindicum L., Lotus corniculatus var. Japonicus Regel, Veronica linariaefolia Pallas, Aster koraiensis Nakai., Chrysanthemum zanadskii var. latilobum(Maxim.) Kitamura, Lythrum anceps Makino 및 Iris nertschinskia. Lodd}을 공시하였으며, 충남대학교 농과대학 초지시험포장에서 2005년 1월부터 2006년 12월까지 수행하였다. 공시된 잔디형 목초 중에서 상대적으로 야생화와 혼파가능성이 큰 초종은 Kentucky bluegrass이었으며, Kentucky bluegrass에 비하여 상대적으로 초기생육이 왕성하고 경엽과 근중이 높아 야생화초지를 조성하는 데 유리할 것으로 보이는 야생화는 Chrysanthemum leucanthemum L., Lotus corniculatus var. Japonicus Regel, Chrysanthemum zawadskii var. latilobum (Maxim) Kitamura 및 Lythrum anceps Makino 등으로 조사되었다. 이들 야생화는 꽃색, 개화시기 및 개화지속기간 등이 서로 중복되지 않았으며 가축에 의한 기호성도 대체적으로 양호한 결과를 보였다. 따라서 야생화초지의 조성을 위해서는 잔디형 목초는 야생화와의 경합력이 낮은 초종을, 반대로 야생화는 경합에서 유리한 초종을 선발하되 개화특성이 서로 다른 야생화를 다양화하여 혼파조합을 구성하는 것이 중요하다고 판단된다.

We investigated major plant communities and seed dispersal patterns in areas a(alt. 2,263 ~2,350m),b(alt. 2,350~2,420m), c(alt. 2,420m) with levels of a crater on mt. paektu. Thirty two species distributed around chunji consisted of 24 perennial herbs, 1 biennial herb and 7 alpine dwarf shurbs. Their fruit types were quite diverse; capsule(11), achene(10), grain(4), legume(2), follicle(2), schizocarp(2) and drupe(1). in area a, adjancent to the chunji(lake) water surface, gramineae sp., cyperaceae sp., chrysanthemum zawadskii and bistorta ochotensis were occured as members of the major plant communities. Species of gramineae and cyperaceae seem to have become dominant because their seeds float well. Astragalus membranaceus is legume and endures the winter cold and summer drought. in area c, alpine dwarf shrubs (e. g.rhododendron redowskianum, rhododendron aureum, empetrum nigrum) were dominant. In area c, compared to a and b, the weather is drier because of strong wind and lower water holding capacity of the soil. Therefore the pattern of plants distributing around chunji is different from that in western slope on mt.paektu. environmental factor such as wind, temperature and water may contribute to the pattern.

In this study, we analyzed flower tea activity against oral bacteria. Lagerstroemia indica, Paeonia suffruticosa and Hemerocallis fulva showed high extract yields. Bellis perennis, Punica granatum and Cercis chinensis showed the high rates of yield by ethanol extraction. Extract yield seemed to be related to the characteristics of the specimens rather than to the solvent. Streptococcus mutans, Streptococcus obrinus, Porphyromonas gingivalis and Prevotella intermedia were used to investigate extracts activity against bacteria; the former two cause dental caries and the latter two cause halitosis. Cornus officinalis, L. indica, P. granatum and P.s uffruticosa showed high antibacterial activities against S. mutans. In specimens extracted with ethanol, P. suffruticosa, Camellia sinensis, Camellia japonica L. and Rosa hybrida showed high antibacterial activities. L. indica, P. granatum and C. officinalis showed high antibacterial activities against S. sobrinus. C. officinalis, P. granatum, L. indica and P. suffruticosa showed high activities for specimens extracted with ethanol. The results show that the warm extracts of C. officinalis, L. indica and P. granatum may be effective to prevent dental caries. In particular, the ethanol-based extracts of C. officinalis, P. suffruticosa and C. sinensis were effective to prevent dental caries and thus may be highly marketable. Chrysanthemum zawadskii, R. hybrida, P. granatum, C. japonica L. and Zinnia elegans showed high antibacterial activity against P.gingivalis. R. hybrida showed the highest ethanol extract activity, followed by P. suffruticosa, P. granatum, C. japonica L. and L. indica. R. hybrida, P. granatum, C. morifolium and C. japonica showed high activity against Pr.intermedia in the order named. C. zawadskii, P. granatum, L. indica, C. japonica and A. princeps showed high ethanol extract activity. Thus, the warm extracts of R. hybrida, P. granatum and C. japonica may be helpful to reduce halitosis. In addition, the ethanol-based extracts of P. granatum, C. japonica and L. indica are expected to be highly marketable as mouthwashes.
