This study was carried out to investigate the soil salinity and salt spray drift of the indigenous windbreak trees, and its main purpose was to provide basic data for the selection of salt-tolerant trees in the saline coastal region in the South Sea of Korea. The soil salinity($EC_{1:5}$)was $0.18dSm^{-1}$, which was an average degree of the whole areas of investigation whose salinity degree ranged from $0.05dSm^{-1}$ to $0.58dSm^{-1}$. The level of soil salinity gradually decreased as it moved farther inland, except the belt I. The level of decreasing soil salinity was found to be in the following order: belt II, belt III, belt I, belt IV. The degree of soil salinity was $EC_{1:5}$ $0.22dSm_{1:5}$, $0.22dSm_{1:5}$ $0.19dSm^{-1}$ and $0.13dSm^{-1}$ respectively. The total 110 taxa, which consisted of 45 families, 74 genus, 101 species, and 9 varieties, were found to be tolerant to both soil salinity and salt spray drift. The trees that grow in the highest degree of salinity($EC_{1:5}$ $0.50dSm^{-1}$)were Parthenocissus tricuspidata(Siebold & Zucc.), Planch and Lonicera japonica Thunb. The next group of trees that grow in the high degree of salinity ranging from $EC_{1:5}$ 0.41 to $0.50dSm^{-1}$ was Cudrania tricuspidata(Carr.) Bureau ex Lavall$\acute{e}$e, Rubus parvifolius L., Zanthoxylum schinifolium(Siebold & Zucc.), Hedera rhombea(Miq.) Bean., Robinia pseudoacacia L., Quercus serrata Thunb., Callicarpa dichotoma(Lour.) K. Koch, and so on. The woody species which grew in the entire belts were Pueraria lobata(Willd.) Ohwi and Vitis flexuosa Thunb., and Vitex rotundifolia L. f. which was known to be highly tolerant to salt spray drift was found only in belt I. The woody species with high important value(IV) were Zelkova serrata(Thunb.) Makino., Celtis sinensis Pers., Koelreuteria paniculata Laxmann, Mallotusjaponicus(Thunb.) Muell. Arg., Trachelospermum asiaticum(Siebold & Zucc.) NAKAI, and Pueraria lobata(Willd.) Ohwi. These species were classified as native windbreak trees that are comparatively more tolerant to salt spray drift than other kinds.

The purpose of this study is verification of the anti-oxidant effect and anti-inflammatory effect of Eggplant-cheongyeolsodokum composed of 8 herbs (Solanum melongena L., Lonicera japonica Thunb., Glycyrrhiza uralensis Fisch., Ligusticum chuanxiong Hort., Angelica gigas Nakai., Coptis deltoidea C. Y. Cheng et Hsiao., Gardenia jasminoides J. Ellis., Forsythia suspensa Vahl) to confirm the possibilities as useful cosmetic material. We used the modified prescription of 'cheongyeolsodokum' contained in Korean traditional medical book 'Donguibogam' as composition of Eggplant-cheongyeolsodokum and their proportions. Eggplant-cheongyeolsodokum were extracted with hot water, 70% ethanol and then powdered. To confirm anti-oxidant effect, we investigated radical scavenging ability (DPPH, $ABTS^+$, superoxide), superoxide dismutase (SOD)-like activity, total polyphenolic contents. Also to confirm anti-inflammatory effect, we investigated inhibition effect of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages, and Inhibition effect of the expression of inflammatory-related proteins (iNOS, COX-2) by western blot analysis. As a result, Eggplant-cheongyeolsodokum showed good anti-oxidant and anti-inflammation effects, we suggest that it can be used as an active ingredient for cosmetics.
