Securing sufficient planting strip for street shrubs has a limitation. So many different shrubs which have been planted in the streets looks consider its visual aspect rather than growth characteristics. In this study, we compared with the growth condition of planted shrubs and construction condition of its planting strip. $Photinia$ $glabra$, $Euonymus$ $japonicus$, $Camelia$ $sasanqua$, $Nandina$ $domestica$, $Abelia$ $grandiflora$ were selected in the Busan City, Korea. The planting strips width were 0.5~0.9m which is not relatively different by each species. Species which have narrow growth character of root hair in the natural bed ($Nandina$ $domestica$, $Abelia$ $grandiflora$) have a good growth condition in the street planting strip, oppositely shrubs which have wide growth character of root hair ($Photinia$ $glabra$, $Euonymus$ $japonicus$, $Camelia$ $sasanqua$) have a relatively bad growth condition. Hereupon, there have a necessity which should be select the different shrub species for the planting strip of the street.

This project was conducted to development several camellia tea mixed herb teas having any physiological effects. Leaves of tea tree contain many compounds, such as polysaccharides, volatile oils, vitamins, minerals, purines, alkaloids(eg. caffeine) and polyphenols(catechins and flavonoids). Although all three tea types(green, oolonr and black) have antibacterial and free radical capturing(antioxidizing) activities, the efficacy decreases substantially the darker the variety of tea is. This is due to lower contents of anti-oxidizing polyphenols remaining in the leaves. Unlike tea tree(Camellia sinensis), the biochemical features and effects of camellia(Camellia japonica) are not well known. Fresh mature leaf of sasanqua camellia(C. sasanqua), roasted young leaf tea(C. japonica) and fresh mature leaf and bark of camellia had high antibacterial activity against P. vulgaris and B. subtilis. In antifungal activity bioassay, young leaf roasted teas of camellia and sasanqua camellia had high activity against C. albicans and T. beigelil. Plant extracts from Camelia japonica had higher inhibitory activity against fungi than against bacteria. In cytotoxic effect against human acute myelogenous leukaemia cell extracts including fresh leaf(200$\mu\textrm{g}$/m1), bark(230$\mu\textrm{g}$/ml) and flower tea (320$\mu\textrm{g}$/m1)inhibited growth of AML cells.(중략)
