In this study we examined the concerned literature for clinical use of Balsaminaceae plants focusing on the latest literature "zhong hua ben cao"(chinese materia medica, 1998). The findings were summarized as follows: 1. As an original plant, 27 species have been reviewed. 2. As a result of investigating oriental drug names by medicinal using part, a survey reported that the total of 22 species of oriental drug names, including 14 species of herba, 3 species of flos, 4 species of radix and rhizoma, and 1 species of semen, are being used for clinical use. 3. When we examined oriental drugs with five flavors by calculating and arranging their nature, effect, toxicity with points for conveniences sake, pungent and bitte showed 13 points, respectively, as main flavors. In drug nature, warm property of drug indicated 10 points and cold property of drug obtained 6 points. But as for other oriental drug, it is thought that we can recognize their significance. 4. With respect to efficacy, activating blood drug reached 10 kinds and wind- damp-dispelling 7 kinds, according to the examination. 5. In the examination on components and medicinal action, we examined that components are recorded in only impatiens balsamina's whole grass, flowers, root, root stems, and seeds, and Impatiens noli-tangere's whole grass. In medical action, we found out that the components are recorded in impatiens balsamina' flowers and seeds; impatiens noli-tangere's whole grass and flowers; and Impatiens textori' whole grass. 6. As a result of examining clinical prescription, the total of 84 kinds of clinical prescriptions by disease nature were examined, of which the prescription of Impatiens balsamina showed 19 cases in total, which was remarkable.

Impatiens balsamina Linne(Balsaminaceae) known as 'BONG SUN HWA' in Korea and has been used for the treatment of scrofulosis, carbunculus and dysenteria etc. Bioassay-guided fractionation of MeOH extract from the whole plants of Impatiens balsamina has afforded a simple naphthoquinone derivative, 2-methoxy-1,4-naphthoquinone. The structure of this compound was established by spectroscopic methods. This compound possessed strong antifungal activity against Candida albicans, AspergiIlus niger, Crytococcus neoformans and Epidermophyton floccusum. The activity of 2-methoxy-1,4-naphthoquinone on E. floccusum $(MIC{\;}:{\;}5.0{\;}{\mu}g/ml)$ was the same potency as that of nystatin. It showed also strong antibacterial activity against gram-positive bacteria Bacillus subtilis as well as gram-negative bacteria Salmonella typhimurium. Although the activity of this compound on gram-negative bacteria was lower than that of gram-positive bacteria.

The flora of the Sinpyeong and Churyeong stream were listed 324 taxa; 87 families, 227 genera, 289 species, 1 subspecies, 31 varieties and 3 forms. The Sinpyeong stream were 249 taxa and Churyeong stream were 221 taxa. Based on the rare plants (IUCN) by the Korea Forest Service and Korea National Arboretum were recorded; Penthorum chinense (Crassulaceae), etc. and endemic plants, 6 taxa; Weigela subsessilis (Caprifoliaceae), Lycoris flavescens (Amarylidaceae), etc. Based on the specific plants by floral region were total 12 taxa (3.7% of all 324 taxa of flora); Monochoria korsakowi (Pontederiaceae), etc. in class III. 10 taxa (Salix glandulosa (Salicaceae), Ulmus parvifolia (Ulmaceae), Impatiens noli-tangere (Balsaminaceae), Grewia biloba var. parviflora (Tiliaceae), Nymphoides peltata (Gentianaceae), Actinostemma lobatum (Cucurbitaceae), Cirsium pendulum (Compositae), Microstegium japonicum (Gramineae), etc.) in class I. Based on the naturalized plants, 51 taxa and ecosystem disturbing wild plants, 6 taxa (Rumex acetosella, Sicyos angulatus, Aster pilosus, Ambrosia artemisiaefolia, Hypochaeris radicata, Paspalum distichum var. distichum) and naturalization rate was 15.7% of all 324 taxa of flora, urbanization index was 18.8% of all 271 taxa of naturalized plants. Based on the hydrophytes, 23 taxa and emergent hydrophytes were 17 taxa, floating-leaved hydrophytes were 3 taxa, submergent hydrophytes were 2 taxa, free-floating hydrophytes was Spirodela polyrhiza.

We investigated the role of competition in adaptation to varying water availability levels for two ecotypically-differentiated populations of Impatiens pallida found naturally in low- vs. high-water environments. In a greenhouse experiment, seedlings were grown in pure cultures at two densities (n=1 and 2 plants per pot) and in mixed cultures (n=2) under low-, medium- and high-water treatments. The two populations were shown to be genetically distinct across the range of environmental conditions in the greenhouse experiment, confirming previous findings. The two populations had similar morphological responses to density and water availability in pure cultures and mixtures, but the population from the high-water environment showed a greater growth response to high water availability than did the population from the low-water environment and the difference in growth between the two populations decreased from the high-water to low-water treatment. Relative competitive ability of two populations were compared under three different water treatments and two densities. Differential response to watering treatment and density were not reflected in a difference in relative competitive ability. Relative yield totals were significantly greater than 1 overall. The niche differentiation suggested by RYTs>1 may be responsible for the lack of differential competitive effects observed for populations in the three vatering treatments.
