In this study, Ilex serrata Thunb was extracted with 70% methanol and concentrated under reduced pressure to measure its total polyphenol contents; furthermore, we examined the effect of electron donating ability of the various extracts. The extract was fractionated using different solvents such as methylene chloride, ethyl acetate, and methanol to investigate total polyphenol contents and electron donating abilities. The total polyphenol contents were $1,058.59{\pm}85.85{\mu}g\;GAE/mL$ in 70% methanol, $297.29{\pm}29.43{\mu}g\;GAE/mL$ in methylene chloride, $313.28{\pm}9.22{\mu}g\;GAE/mL$ in ethyl acetate, and $837.82{\pm}31.16{\mu}g\;GAE/mL$ in methanol. The total polyphenol contents showed significant differences (p<0.05) between the solvents. The electron donating abilities were $72.93{\pm}0.29%$ for 70% methanol extract, $14.02{\pm}2.01%$ for methylene chloride, $24.05{\pm}1.75%$ for ethyl acetate, and $84.08{\pm}1.95%$ for methanol. The electron donating abilities were significantly different (p<0.05) between the solvents. The two portions of Ilex serrata Thunb extracts obtained from methanol showed significantly relevant results in the total polyphenol contents and electron donating ability, which was higher than the original extract.

To investigate the vegetation structure of mountain ridges ranging from Sebong to Gwaneumbong 23 plots($400m^2$) set up with random sampling method were surveyed. Two groups of Pinus densiflora community, Pinus densiflora-Quercus variabilis-Quercus serrata community were classified by cluster analysis. Pinus densiflora, Quercus variabilis, Quercus serrata, Carpinus laxiflora, and Quecus mongolica were found as a mostly dominant woody plant species in the ridge area from Sebong to Gwaneumbong. In the future, the importance percentage of Pinus densiflora might be decreased, but those of Quercus variabilis, Quercus serrata, Carpinus laxiflora, and Quecus mongolica might be increased. High positive correlations were proved between Quercus variabilis and Fraxinus sieboldiana, Acer palmatum and Ilex macropoda, Cornus kousa and Platycarya strobilacea, Sorbus alnifolia and Carpinus laxiflora, and relatively weak negative correlations were proved between Pinus densiflora and Carpinus laxiflora, Fraxinus sieboldiana and Carpinus laxiflor, Quecus mongolica and Sorbus alnifolia, Ilex macropoda and Sorbus alnifolia. Species diversity index(H') of investigated groups was ranged $0.665{\sim}1.169$.

This study is to examine the environmental characteristics of subpopulations of Ilex crenata var. microphyllla Max. distributed in the east-west slopes of Mt. Halla National Park based on analyzing the factors of environment, vegetation and soil. The result of the TWINSAPN analysis conducted on 56 study plots between the altitudes of 500 m and 1600 m of east-west slopes of Mt. Halla National Park can be divided into five communities-Prunus maximowiczii Rupr., Manshurian fullmoon Maple, Carpinus tschonoskii Max., Daphniphyllum macropodum Miq., Quercus serrata Thunb. ex Murray and Pinus thunbergil Parl. Among these communities, the plot with high importance percentage of the subpopulation of Ilex crenata var. microphyllla Max., is the Carpinus tschonoskii Max.-Daphniphyllum macropodum Miq. included in the altitude of 600m~1200m radius. The dominant species of the upper shrub layer was Carpinus tschonoskii Max.(I.P.: 29.82%) while the dominant species of the canopy layer was Daphniphyllum macropodum Miq.(I.P.: 26.76%). For the understory layer the dominant species was Ilex crenata var. microphyllla Max.. Species diversity index was on the low end with 0.7424, indicating the stably formed climax community of Carpinus tschonoskii Max.. The analysis of soil properties showed high concentrations of organic matters, available phosphate and Ca, Mg, the high importance percentage of the of Ilex crenata var. microphyllla Max. is found in altitude of 600m~800m on the eastern slope and the altitude of 800m~1,000m radius on the west slope. This region is included in the southern part of the cold/hot forest zone, its high importance percentage of Carpinus tschonoskii Max. and low in the species diversity index of 0.7424, and has formed stable climax community of Carpinus tschonoskii Max. in Mt.
