Flora of vascular plants in mountains located at Wonju-si and Hoengseong-gun areas such as Chiak-san(1,288m), Taegi-san(1,261.4m), Obong-san(1,126.2m), Eungbong-san(1,094.9m), Eodab-san(789.4m), Deokgo-san(521.2m), Deokga-san(700.5m) and Seongji-bong(791m) was investigated from April, 2008 to May, 2009, and results from the previous researches in which voucher specimens had been presented from Balgyo-san(998.4m), Oeum-san(930.4m), Baekun-san(1,037.1m) and Chiak-san(1,288m) were included in the list of vascular plants from these areas. This investigations resulted in 804 taxa consisted of 680 species, 1 subspecies, 111 varieties, and 12 forms of 383 genera under 97 families, and totally in 973 taxa (21.14% of all vascular plants in Korea) of 818 species, 1 subspecies, 138 varieties and 16 forms of 418 genera under 105 families on addition of voucher specimens in the previous researches. Forests of the investigated areas were generally mixed of Pinus densiflora and deciduous trees. The areas with comparatively excellent vegetation were valley from Guryong-sa (temple) to Biro-bong (summit) via Seryeom-pokpo (fall) in Mt. Chiak-san, and Keunseong-gol (valley) and eastern slope from Taegibungyo-teo to Naksu-dae (fall) in Mt. Taegi-san. 10 families with abundantly collected species were Compositae, Graminae, Rosaceae, Ranunculaceae, Leguminosae, Cyperaceae, Liliaceae, Saxifragaceae, Umbelliferae and Labiatae in order, and they occuied 49.12% of all collected taxa. Endemic plants found in these areas were 38 taxa including Hanabusaya asiatica, Megaleranthis saniculifolia, and Pyrus ussuriensis var. diamantica, and rare and endangered ones were 24 taxa including Hanabusaya asiatica, Viola websteri, Viola diamantica, and Patrina saniculaefolia. Specially designated plants by the Ministry of Environment were 88 taxa including 12 taxa of 5th degree such as Woodsia intermedia, Hanabusaya asiatica, Equisetum pratense, Iris koreana, Lilium cernum, Trillium tschonoskii, Magnolia kobus(cultivated), Gastrodia elata, Polypodium virginianum, Cimicifuga heracleifolia, Megaleranthis saniculifolia and Viola websteri. 47 taxa of alien plants were found. As to 609 taxa (13.23% of all vascular plants in Korea) of useful plants, 334 taxa for the edible, 269 taxa for the medicinal, 127 taxa for the ornamental, 332 taxa for the forage, 3 taxa for the industrial raw material, 31 taxa for the timber and 13 taxa for the fiber were classified, respectively.

Woo, Jeong-Hyang ; Shin, So-Lim ; Chang, Young-Deug ; Lee, Cheol-Hee ;
Korean Journal of Plant Resources, volume 22, issue 5, 2009, Pages 381~388
Antioxidant substances were extracted from flowers of Aster scaber, Aster maackii, Coreopsis lanceolata and Coreopsis tinctoria using 2 types of extraction methods- ultrasonic wave and reflux, and antioxidant effects were compared. Higher yield of extract was obtained by ultrasonic wave method in all 4 species. Extraction time was different depending on species, but in all 4 species DPPH and ABTS free radical scavenging and ferrous ion chelating activity were higher or similar by ultrasonic wave than reflux method. Content of total polyphenol and flavonoid was mainly higher by ultrasonic wave than reflux method. Longer the treatment, the more the antioxidant activity and bioactive substances. Anti-lipid peroxidation of ultrasonic and reflux extracts obtained from flowers of Aster scaber and Coreopsis lanceolata were compared. Flower extract of Aster scaber obtained by reflux method showed the highest inhibition effect against peroxidation of linoleic acid, but extract of Coreopsis lanceolata obtained by 15-minute ultrasonic extract showed the highest effect. Ultrasonic wave extraction was more economical and efficient method than reflux extraction.

Lee, Bo-Duk ;
Korean Journal of Plant Resources, volume 22, issue 5, 2009, Pages 389~393
Regional distribution of mistletoe (Viscum album var.coloratum) and its habitual environments were investigated in order to obtain the basal data on the artificial propagation to cope with its increasing consume for medicine. Mistletoes inhabited throughout the overall region of the South Korea investigated. They were parasitic mainly to the Quercus spp. including Q. serrata and rarely to the Castanea crenata var. dulcis, Prunus serrulata var. spontanea, Alnus japonica, and Pyrus pyrifolia, etc. Mistletoes were not observed on the conifers such as Pinus densiflora and Pinus koraiensis and some deciduous broad-leaved trees species such as Zelkova serrata, Diospyros kaki, Acer mono, Acer palmatum, and Morus alba. Their habitats were located from zero to 1,200 m above sea level nevertheless the direction or slope of the mountains, suggesting that artificial propagation can be carried out nation widely to the well-grown parasite tree species. Parasitic specificity related to the physical and chemical characteristic of the epidermal tissues will be studied further.

Shin, So-Lim ; Lee, Cheol-Hee ;
Korean Journal of Plant Resources, volume 22, issue 5, 2009, Pages 394~402
Adventitious shoots were induced from pinnae, petiole and rhizome in Pteris cretica 'Wilsonii' in order to develop the efficient mass propagation method, using in vitro culture. Only homogenized rhizome segments could regenerate young sporophytes. Efficient regeneration of multiple shoots was obtained on the one-eighth strength MS medium containing 1% sucrose, and
. To achieve higher rate of regeneration from rhizome segments, rhizome segments were exposed to growth regulators for 2 months and then subcultured on hormone-free medium. The greatest shoot regeneration was obtained by
NAA. BA was effective in formation of GGB (kind of meristems), but they showed low shoot regeneration rate. Plants obtained from present experiments were transplanted to examine good environmental conditions for acclimation. Juvenile plants obtained by the one-eighth strength MS medium showed highest survival rate and vigorous growth at the seedling stage.

This study was conducted to gather the basic data on the increase of utilization for the Japanese staunton vine (Stauntonia hexaphylla), native plants which were grown in the southern districts in Korea. We have also determined their partial physical and chemical compositions and their physiological activities. Vitamin C contents in fruit skin was 85.23 mg/100 g, and that in flesh was 61.67 mg/100 g. Total amino acids contents in fruit skin increased much more by 762.72 mg/100 g DW compared to that in flesh by 434.05 mg/100 g DW. Inorganic matter contents were more increased in the fruit skin (108.48 mg/
) and its main components were K (76.53 mg/
), Ca (20.20 mg/
) and Mg (6.22 mg/
). Total phenol compound and flavonoid contents in 1,000 mg/
methanol extracts were 7.3-9.6 mg/
and 5.1-6.7 mg/
. Nitrite radical scavenging activity in 4,000 mg/
methanol extracts of fruit skin and flesh for Stauntonia hexaphylla were 79.5% and 77.8%, however, that in seeds was 17.1%. Overall mushroom tyrosinase inhibition activity (% of control) was less than 10.8%. Anti-microbial activities of methanol extracts from the fruit skin against the gram negative and positive microbial strains were not significant in the lower concentration of extracting solution, however, that from flesh and seeds in terms of the inhibition diameter were

The flora and vegetation of Chuncheon area were investigated from March, 2006 to September, 2008. Vascular plants of investigated regions were composed of 118 families, 496 genera, 894 species, 2 subspecies, 132 varieties, and 38 forms, totally 1,066 taxa, and the Pteridophyta index (Pte-Q) was 1.17. Forty two taxa including endemic genus Hanabusaya and Echinosophora among the 1,066 taxa were Korean endemic. Thirty three rare and endangered plants and 119 specially designated plants by Ministry of Environment were also investigated. The naturalized plants were 71 taxa, and percent of naturalized plant species were 6.66%. The vegetation of Chuncheon area were classified into five communities such as Quercus mongolica community, Pinus densiflora-Quercus mongolica community, Quercus mongolica-Acer mono community, Quercus mongolica-Quercus variabilis community and Quercus mongolica-Betula davurica community.

Rhim, Tae-Jin ; Choi, Moo-Young ;
Korean Journal of Plant Resources, volume 22, issue 5, 2009, Pages 425~430
The objective of this study was to investigate the antioxidative capacity of oregano extracts. Amount of oregano extract at which DPPH radical scavenging activity was inhibited by 50% was
as compared to 100% by pyrogallol as a reference. Total antioxidant status was examined by total antioxidant capacity against potent free radical reactions. Total antioxidant capacities of oregano extract at the amounts of 7.5 and
were 15.1 and 31.4 nmol Trolox equivalents, respectively. Oxygen radical absorbance capacities of oregano extract at the amounts of 0.2 and
were 1.4 and 2.4 nmol gallic acid equivalents, respectively. Total phenolic contents of oregano extract at the amounts of 30 and
were 40.5 and 83.9 nmol gallic acid equivalents, respectively. The inhibitory effect of oregano extract on lipid peroxidation was examined using rat liver mitochondria induced by
/ascorbic acid. Oregano extracts at the amounts of 20 and
decreased TBARS level by 20 and 64%, respectively. Thus strong antioxidant effects of oregano extract seem to be due to, at least in part, the prevention against free radicals-induced oxidation, followed by inhibition of lipid peroxidation.

Korean Journal of Plant Resources, volume 22, issue 5, 2009, Pages 431~437
To investigate the anti-inflammatory effect of Ephedrae Herba in vivo and in vitro acute inflammation was induced by lipopolysaccharide (LPS) shock in rats fed Ephedrae Herba extracts and inflammatory cytokine concentrations were examined. In addition, the effect of Ephedrae Herba extracts on the production of inflammatory cytokines was examined in LPS-stimulated Raw 264.7 cells. In an in vivo experiment, plasma interleukin-
), interleukin-6 (IL-6), interleukin-10 (IL-10) and tumor necrosis factor-
) concentrations were increased at 2 h and reached to maximal levels at 5 h after LPS treatment in all groups. Compared with control group, plasma IL-
, IL-6, and TNF-
levels were lowered at 5 h after LPS treatment, but plasma IL-10 level was higher in at 2 and 5 h after LPS treatment in Ephedrae Herba extract group. In an in vitro experiment using Raw 264.7 macrophages, IL-
, IL-6 and TNF-
concentrations in the Ephedrae Herba extract group were lower than those in control group. Compared with control group, IL-10 concentration appeared to be higher in the Ephedrae Herba extract group, but this trend was not significant. In conclusion, these results suggested that functional compound (s) in Ephedrae Herba extract may play a role in alleviating inflammatory response.

RAPD analyses were performed to investigate genetic relationships and useful molecular maker for 3 species and their 17 regional populations of the Pueraria lobata and related taxa. The length of amplified DNA fragments ranged from 200 to, 2,800 bp. Two hundred and eight scorable polymorphic makers and three scorable monomorphic makers were found from the PCR reactions with 15 random oligo primers, and those were analyzed by Nei's genetic distance coefficient. Based on the UPGMA phenogram from RAPD analyses, two major groups (9 populations from Korea; 3 populations from foreign countries) were recognized. And it showed distinct genetic differences from related taxa. The RAPD results was very useful to define the samples by geographical distribution and to discuss the relationships among the populations and their related taxa of the Pueraria lobata.

Phyllanthus urinaria was an important species in Korea and distributed in all around of Korea. The roots and stems of this plant have been used for natural medicine for the treatment of diabetes, the hepatitis B virus and disturbances of the kidney and urinary bladder. Production of adventitious roots in P. urinaria by in vitro cultures could be used as alternatives materials. Shoot and root segments from P. urinaria seedling were cultured on Murashige and Skoog (MS) medium supplemented with 3.0 mg/L IBA and 30 g/L sucrose. After 4 weeks of culture, the highest induction of adventitious roots was obtained from the shoot part. Frequency of adventitious root formation on medium with various kinds of auxins (IAA, NAA, 2,4-D, and IBA) and various concentrations of IBA (0, 0.1, 0.5, 1.0, 3.0, and 5.0 mg/L) was tested. The maximun induction of adventitious root was obtained on medium with 0.5 mg/L IBA. In liquid culture, growth of root was best on medium supplemented with 30 g/L sucrose. Adventitious roots were cultured in 5 L bioreactor containing 1/2 MS medium supplemented with 0.5 mg/L IBA and 30 g/L sucrose and mass-production of adventitious roots was successfully achieved. These results revealed the first attempt for the production of adventitious roots in P. urinaria.

This study was carried out to evaluate the effects of yam (Dioscorea batatas Dence) extracts on the cell viability, growth and nucleus-DNA damage of tobacco cells which were exposed to
-radiation stress. The viability and growth of tobacco cells exposed to 20 Gy of radiation stress were effectively recovered by pretreatment of 10 mg/L ethylacetate (EtOAc) yam extract. Pretreatment of EtOAc extract showed 20% higher cell viability and fresh weight growth than that of cells without pretreatment in 20 Gy radiation treated tobacco cells. Nucleus-DNA damage was measured as the ratio of tail length (T) to head length (H) in individual comet image isolated from tobacco cells. The T/H ratio of control-cells and treated-cells at 20 Gy were 1.05 and 1.68, and % head DNA of those cell were 86.7 and 71.3%, respectively, suggesting that nuclei of tobacco cells were severely damaged in the integrity of DNA by the treatment of
-radiation. However, pretreatment of MeOH, EtOAc and n-BuOH extracts decreased radiation induced DNA-damage in the tobacco cells, showing T/H ratio of 1.37, 1.01 and 1.10 and % head DNA of 81.5, 87.6 and 88.7%, respectively.

Korean Journal of Plant Resources, volume 22, issue 5, 2009, Pages 467~472
This study was conducted to break down the self-incompatibility of Astragalus membranaceus Bunge by old-flower pollination, NaCl and
treatment. The old-flower pollination in green house produced fertilization during the 1st and 2nd day after flowering from early September to early October, but almost no fertilization in late August. The most successful pollination occurred in late September at the 1st day after flowering when pod setting was 33.3% and that of seed set was about 86.2%. The old-flower pollination in field showed pod setting for the control group from late August to early October, but no seed set except the days of mid-September and late September. The most successful pollination occurred in late September during the 2nd day of flowering when the percentage of pod setting was 39% and that of seed set was 94.9%. The wrapping in field set pods from late August to early October, but did not set seeds except in mid and end of September. The percentage of pods was 39% and percentage of seeds was 94.9% about flowering after first day in end of September. by field culture. The best result from NaCl treatment was achieved when 1% NaCl treatment in green house produced 21.3% of pod setting in early October and 66.7% of seed set in late September. In field, NaCl 5% treatment produced best result with 7.3% of pod setting and 90.9% of seed set in mid-September. No differences were observed between the
700ppm treatment and the control group.

Inhibitory Effect of Muscat Bailey A Seed Extract on Melanin Production in
-Melanin Stimulating Hormone-stimulated B16 Cell
Lee, Pyeong-Jae ;
Korean Journal of Plant Resources, volume 22, issue 5, 2009, Pages 477~482
Inhibitory effect of skin and seed of three species grape cultivated in Korea on melanogenesis was investigated. Melanin generation was examined in
-Melanin Stimulating Hormone-stimulated B16 cell, mouse melanoma, in the presence of samples. All skin sample did not show the inhibitory effect. Seed extract of Campbell early and Neo Muscat had negative effect on cell viability. When
seed extract of Muscat Bailey A was treated, amount of generated melanin and cell viability were
compared to control, respectively. Seed extract of Muscat Bailey A reduced the tyrosinase protein induced by
-Melanin Stimulating Hormone, which suggests that inhibitory effect of seed extract of Muscat Bailey A on melanin is partly due to suppression of tyrosinase that is responsible for melanin production.
