Sambucus williamsii var. coreana have been used as a traditional medical food. This research was conducted to investigate the antioxidants of S. williamsii var. coreana leave and stem extracts. Total phenolic content of S. williamsii var. coreana leaves and stem water extracts were 6.6 and 2.0 mg/mL. The EDA by DPPH free radical scavenging test of S. williamsii var. coreana leaves extracts were 99.5 and 89.7% in water and ethanol extracts contained phenolic 200
. The stem extracts were 92.2 and 94.3% in water and ethanol extracts contained phenolic 200
. The ABTS radical decolorization activity of water and ethanol extracts from leaves were 79.8 and 99.1% at phenolic 200
and water and ethanol extracts from stem were 90.8 and 97.2% at phenolic 200
. The antioxidant protection factor of water and ethanol extracts from leaves were 1.1 PF and 1.1 PF at phenolic 200
and water and ethanol extracts from stem were 1.4 PF and 1.0 PF at phenolic 200
. The TBARs of water and ethanol extracts from leaves were 88.7 and 98.1% at phenolic 200
and water and ethanol extracts from stem were 93.6 and 90.6% at phenolic 200
. The antioxidative activities of extracts from S. williamsii var. coreana leaves and stem were higher than BHT as positive control. These results suggests that S. williamsii var. coreana extracts have the greatest property as a natural antioxidative source.

DOI : 10.7732/kjpr.2012.25.4.379
This study was conducted to compare and analyze change of content of polyphenol and p-hydroxybenzyl alcohol (HBA), which is an index-component, and antioxidant activity between fermented Gastrodia elata Blume and non-fermented G. elata Blume. The polyphenol contents before and after the fermentation were 108.65 and 389.99 mg/mL respectively, and the content of index-component HBA increased from 2.46 mg/g before fermentation to 7.94 mg/g after fermentation. In comparison between the non-fermented G. elata Blume extract (NFGE) and fermented G. elata Blume extract (FGE) in DPPH, ABTS, and superoxide radical scavenging assay, we found that FGE showed more activity than NFGE as the extract was more concentrated. Especially, the superoxide radical scavenging activity was increased more than twenty times in FGE. In conclusion, we confirmed increase in the electron donating ability and radical scavenging when the dried G. elata Blume is fermented, and its further feasibility as an antioxidant.

DOI : 10.7732/kjpr.2012.25.4.387
In order to improve storability of subtropical yam produced in South Korea, the major pathogens found during the storage were isolated and identified of the pathogenicity, and rot inhibition effect was studied based on the curing treatment condition. Penicillium sclerotigenum and Penicillium polonicum were identified as major pathogens causing rot in subtropical yam during storage, and P. sclerotigenum had stronger pathogenicity. Only the cut surface which has been made during a harvest and has been made smooth before curing generated a normal callus layer. The cut surface of tuberous root was cured in 95% of relativity humidity for three days at
, and cured at
. The observation of callus layer showed that the
treatment group had similar color saturation between tuberous root and pellicle, while the groups treated above
showed clear distinction. The generation rate of callus 0.5mm or bigger was 93 percent at
treatment, 96% at
treatment, but was 52% at
treatment. The conventional curing treatment group that used wind or sunlight at room temperature created little callus layer. The infection rate of pathogens according to the relative humidity inside the storage room was low at 40% and 60% of humidity, and the curing treatment period did not make a difference. When the humidity inside the storage room was 80%, all treatment groups rapidly increased the fungal pathogens. The rotten rate of each treatment was studied after 180 days during which the storage temperature was maintained at
and relative humidity 60%. While the rotten rate of tuberous root that has been cut in conventional curing treatment based on solar and wind was 43%, the one cured at over
and created the callus layer was less than 18%. While even a healthy tuberous root showed 25% of rotten rate in the traditional treatment group, the one cured at over
was less than 10%. The weight loss was 1-6% lower in the forced treatment group than in the conventional treatment group.

DOI : 10.7732/kjpr.2012.25.4.394
Contents of soyasaponin group B were compared according to two regions and ten varieties by HPLC. Those compounds were known to be beneficial for health. After soyasaponins were isolated and identified, those isolated compounds were used for HPLC analysis. The contents of soyasaponin were very different by regions but highest in the soybean with black seed coat. It was appeared that environmental difference for soybean growth could strongly change of soyasaponin contents.

Song, Jeong-Ho ; Lim, Hyo-In ; Jang, Kyung-Hwan ; Kim, Du-Hyun ; Son, Jang-Ick ;
Korean Journal of Plant Resources, volume 25, issue 4, 2012, Pages 401~406
DOI : 10.7732/kjpr.2012.25.4.401
This study was conducted to investigate the effect of cone protective net and the variation of cone and seed characteristics of a unique and rare dwarf stone pine (Pinus pumila Regel) population in Mt. Seorak which is in the southern peripheral of South Korea. Iron protective net (50 mesh, 25
25 cm) was effective in reducing birds and rodents damage to conelet, thereby it was possible to safely collect seed genetic resources. Early July was observed to be the most appropriate season to cover conelet with Iron protective net. P. pumila have ovoid-triangle shaped, wingless seeds and indehiscent cones, seeds dissemination is mainly by the hoarding behavior of nutcrackers and rodents. Statistical analysis showed that there were significant differences among individuals within population, and the mean characteristics of the species were 35.3 mm, 25.6 mm, 1.38, 6.6 g and 39.3 ea in the cone length, cone width, cone index, cone weight and in number of seeds per cone, respectively. Coefficients of variations in seed weight and number of seeds per cone were relatively high (21.7%, 21.5%, respectively) compared to other traits. Based on the correlation analysis between cone characteristics and seed characteristics, the length of cone and seed showed a significant positive correlation with the seed size and the seed weight, but the width and thickness of seed showed a negative correlation with the number of seeds per cone.

Song, Jeong-Ho ; Lim, Hyo-In ; Hong, Kyung-Nak ; Jang, Kyung-Hwan ; Hong, Yong-Pyo ;
Korean Journal of Plant Resources, volume 25, issue 4, 2012, Pages 407~415
DOI : 10.7732/kjpr.2012.25.4.407
Pinus pumila, which occurs in the northeast Asia, is found limitedly in Daecheongbong area of Mt. Seorak in the South Korea. This population was chosen to study spatial pattern, genetic diversity and spatial genetic structure. There were 48 polymorphic and 30 monomorphic I-SSR markers. A total of 65 individuals which distributed in the study site (40 m
70 m) showed weakly aggregate distribution (Aggregate Index = 0.871). A total of 40 genets were observed from 65 individuals through I-SSR genotype comparison. Proportion of distinguishable genotype (G/N), genotype diversity (D) and genotype evenness (E) were 61.5%, 0.977 and 0.909, respectively. In spite of the small number and the limited distribution, Shannon's diversity index (I = 0.567) was relatively high as compared with those of other plant species. Spatial autocorrelation using Tanimoto's distance showed that the genetic patch was established within 12 m. Based on Mantel tests, there was relatively low correlation between genetic distance and geographic distance. Therefore, it seems the P. pumila population was formed by many parent trees in early stage. For ex situ genetic conservation of P. pumila, the sampling strategy is efficient at least above 12 m between individual trees.

The preliminary study for providing the relationship of the factors which are climate and the pteridophyta was carried out. Dormancy form and leaf phenology of the 321 taxa belonging to 27 families were analyzed. This survey shows life-form spectrum of Korean ferns. The results obtained from this study were as follows: Deciduous (d), Evergreen (e) and Summer-deciduous (sd) were calculated as 37.4%, 59.2%, 1.9%, respectively and the Evergreen (e) has the highest value compared to the other leaf phenologies. It observed from the life-form spectra that Hemicryptophytes (H) was the most common dormancy form at 42.1%. Geophytes (G), Epiphytes (E) and Chamaephytes (Ch) were calculated at 25.5%, 15.9%, and 11.8%, respectively. There will be a discussion about geographical distribution of Korean ferns and possibility of their distribution range.

The phytosociological study was carried out to investigate the Corylopsis gotoana var. coreana community structural characteristics and soil environment of Mt. Baegun in Pochen. The vegetation data of total 9 relev
s were analyzed by the Z
rich-Montpellier school's method. Three communities of Mt. Baegun were recognized : Corylopsis gotoana var. coreana - Quercus mongolica community, Corylopsis gotoana var. coreana - Carpinus laxiflora community, Corylopsis gotoana var. coreana typical community. The reanalysis to Corylopsis gotoana var. coreana community structural characteristics in south area classified 8 communities by literature. PCA analysis of Corylopsis gotoana var. coreana community distributed in the middle and southern area showed that the Corylopsis gotoana var. coreana community of the Mt. Jiri in the southern area was highly correlated with the one of Mt. Baegun in the middle area.

DOI : 10.7732/kjpr.2012.25.4.456
This study was conducted to establish the in vitro optimal condition for seed germination and organogenesis of wild Angelica gigas. The experiment was evaluated the effects of
for pre-treatment with different periods of time (0h, 24h, 48h, 72h) and followed the treatment of seeds by control, scarification and methanol-heating method. As a result, the highest rates (15%) of seed germination was shown under the treatment without soaking of
and methanol-heating treatment. The seed germination was highly increased 60% under the condition of treatment on ultrasonic waves (frequency 80 KHz) with methanol-heating treatment including 0.1 mg/L
. The highest callus induction rate was obtained from in vitro germinated stem, root and hypocotyl on the MS medium with 1.0 mg/L NAA and 0.5 mg/L BA. The highest percentages of shooting (50%) and rooting (85%) induction were observed in hypocotyl and root cultured on PGRs free medium and 0.1 mg/L NAA, respectively. In addition, somatic embryogenesis was observed from stem (1.0 mg/L 2,4-D) and hypocotyl (0.1 mg/L NAA).

DOI : 10.7732/kjpr.2012.25.4.465
We examined plants that were used as temple food in Jeju from May 2011 to January 2012. Thirty-six temples participated in the study, and there were 58 questionnaire respondents. Fifty-seven taxa were used as temple food, which belonged to 27 families, 51 genera, 55 species, and two varieties. The most commonly used family-based taxa were eight species of Compositae, six species of Cruciferae, and four species of Umbelliferae. Ten species of woody plants and 25 species of Jeju native plants were also used as temple food. The most useful part was the leaf, followed by the root, leaflet, and fruit. A patent search showed that most of the surveyed plants were covered by intellectual property rights. Forty-eight species had food-related patents, 34 species had cosmetics-related patents, and 38 species had medicine-related patents. The purchase and procurement of Jeju temple food plants usually depended on the market or plant cultivation rather than the use of the plants. Gathering of wild herbs for temple food has been performed on a limited basis. Therefore, collecting traditional knowledge for the use of Jeju plant resources should be conducted under different conditions rather than through a temple-related study.

Korean Journal of Plant Resources, volume 25, issue 4, 2012, Pages 473~481
DOI : 10.7732/kjpr.2012.25.4.473
This study was conducted to investigate the contents of ginsenosides and physiochemical properties of Panax ginseng after 9 times steaming and drying treatment by using the new auto steamer which is more fast and simple than previous report. In the process of steaming and drying, the content of six major ginsenosides such as Rg1, Re, Rb1, Rc, Rb2 and Rd were gradually decreased. On the other hand, the content of seven minor ginsenosides includes Rh1, 20(S)-Rg2, 20(R)-Rg2, 20(S)-Rg3, 20(R)-Rg3, Rk1 and Rg5 were gradually increased. We observed the protopanxadiol ginsenosides such as Rb1, Rb2, Rc and Rd were converted into 20(S)-Rg3, 20(R)-Rg3, Rk1 and Rg5; similarly protopanxatriol ginsenosides of Rg1 and Re were converted into Rh1, 20(S)-Rg2 and 20(R)-Rg2. Based on the result of fresh ginseng, the contents of reducing sugar, acidic polysaccharide and total phenolic compounds were gradually increased and reached to maximum at 7 times repetitive steaming process of the fresh ginseng. Whereas DPPH radical scavenging activities were gradually decreased to 68% at 7 times steaming. New auto 9 repetitive steaming and drying process has similar production with original methods, but content of benzo(a)pyrene were not almost detected comparatively taking less time. The present results suggested that this method is best for the development of value-added ginseng industry related products.

DOI : 10.7732/kjpr.2012.25.4.482
Effect of Trichosanthes kirilowii extract on the inflammatory responsse was investigated in the lipopolysaccharide (LPS)-treated broiler chickens. Plasma ceruloplasmin and
-acidic protein concentrations of all the experiment groups were increased at 3, 9 and 24h after LPS treatment. Plasma ceruloplasmin and
-acidic protein concentrations of Trichosanthes kirilowii extract groups were lower than those of control group. Plasma nitrogen oxide concentration of all the experiment groups was rapidly increased at 3h after LPS treatment. However, plasma nitrogen oxide concentration was decreased at 3 and 9h after LPS treatment with increasing amount of Trichosanthes kirilowii extract added. Liver IL-2 mRNA concentration of all the experiment groups was rapidly increased at 2h after LPS treatment, and then gradually decreased to the level similar to that before LPS treatment at 9h after LPS treatment. Liver IL-2 mRNA concentration of Trichosanthes kirilowii extract groups were lower than that of control group. Spleen IL-2 mRNA concentration was the highest at 4h after LPS treatment in all the experiment groups. Spleen IL-2 mRNA concentration of 0.2 and 0.3% Trichosanthes kirilowii extract groups were higher than that of 0.1% Trichosanthes kirilowii extract group and control group at 3 and 4h after LPS treatment. Liver and spleen IFN-
mRNA concentrations were increased at 2 and 3h after LPS treatment, decreased at 4h after LPS treatment, and then reached to the level similar to that before LPS treatment at 9h after LPS treatment. Liver and spleen IFN-
mRNA concentrations of Trichosanthes kirilowii extract group were lower than those of control group at 2h and 3h after LPS treatment. Liver and spleen iNOS mRNA concentrations were the highest at 3h after LPS treatment, and then decreased to the level similar to that before LPS treatment at 9h after LPS treatment. Liver and spleen iNOS mRNA concentrations of Trichosanthes kirilowii extract groups were lower than those of control group at 2, 3 and 4h after LPS treatment.

Korean Journal of Plant Resources, volume 25, issue 4, 2012, Pages 498~503
DOI : 10.7732/kjpr.2012.25.4.498
The aim of this study is to compare the total polyphenol, total flavonoid, and antioxidative activity among 5 cultivars of Korean pears cultivated in Korea. As a result of the analysis for the phenolic substance of 5 cultivars, such as Wonwhang, Sunwhang, Whangkeumbae, Chuwhang, and Shingo, the content of total polyphenol was higher in Shingo and Chuwhang, and the content of total flavonoid showed higher levels in Wonwhang and Sunwhang. In addition, this study found that DPPH radical-scavenging ability was the highest in Shingo and that the part of fruit skin showed more favorable reaction to radical ability than fruit flesh. It was also found that much better antioxidative activity was shown for the methanol solvent extraction than for the ethanol solvent extraction. The nitrite-scavenging ability showed the best for Wonwhang and Chuwhang of the cultivars and much better reaction for the methanol solvent extraction than for the ethanol solvent extraction just like the case of DPPH radical-scavenging ability. Further, nitrite-scavenging ability appeared much better reaction for the fruit skin than for the fruit flesh, and antioxidative activity dropped for the higher the range on the pH scale. From the results of this study, Korean pears are worthy of developing as a natural functional food and substance for beauty treatment through the research on bioactivity.

DOI : 10.7732/kjpr.2012.25.4.504
Hosta 'Yellow Tiara' was induced using methyle methane sulfonate (MMS) to obtain mutagens. Among the induced leaf-variegated hosta plants, some with yellow-green leaves were selected. They were cultivated via vegetative propagation. Assessment of the botanical characteristics was conducted for three years since 2004. The major characteristic of these cultivars is that they maintain their yellow-green leaves uniformly all year round. These cultivars are useful as materials for pot plants or as ground cover.
