The purpose of this study was to evaluated the antioxidative constituents and their activities of the 80% methanolic extracts from fruit of Sorbaria sorbifolia var. stellipila MAX. The isolation of active compound was performed in three steps: solvent partition, open column chromatography, and high-performance liquid chromatography (HPLC). The solvent fractions were tested for their antioxidant activities by oxygen radical absorbance capacity (ORAC). The antioxidant activity of 80% methanolic extracts by various solvent partitions was in the order of 80% MeOH (1.68
0.027), n-hexane (1.02
0.025), EtOAc (1.98
0.065), n-BuOH (1.94
0.054) and Water (1.28
0.032). Therefore, the results indicated that the potential antioxidant activities and functional values were observed significantly at EtOAc fraction from fruit of S. sorbifolia, flavonoid compound isolated.

A medicinal herb, Stevia rebaudiana Bertoni which is grown under physical stresses such as simulated microgravity, shaking, and low temperature for 4 days, showed fresh weight decrease of 3.6%, 21% and 8.7% compared with the respective control. On control plants, the radical scavenging value of DPPH represented 86% and 55%, respectively in the leaves and stems extracts. Relatively weak antioxidant activities of 22% and 27% were measured respectively in AA (ascorbic acid) and BHA (beta-hydroxyacetic acid) known as synthetic antioxidants. The radical scavenging effect of DPPH (2,2-diphenyl-1-picryl hydazal) in stevia plants under a simulated microgravity was observed to be consistently higher relative to the control, whereas those effects of shaking and low temperature treatments rapidly increased and then reduced after 6 hours in case of shaking process and 24 hours in case of low temperature treatment, which results had similar levels of scavenging effects to the control. The plants under simulated microgravity showed the highest level of activity with the value of 147% and the shaking and low temperature treatments showed the increases of SOD activity by 121% and 125%, respectively. From the above results, it is clarified that the simulated microgravity is more effective to the antioxidant activity than those of other abiotic stresses.

DOI : 10.7732/kjpr.2011.24.4.351
This study was carried out to investigate the effective extraction condition for increase of phytoecdysteroids from fronds of Matteuccia struthiopteris (FMS) and Osmunda japonica (FOJ). Lyophilizated fronds were mixed with three different solvents (MeOH, 80% EtOH or water) and then extraction was carried out by using six different methods, such as, immersion (room temp.), heating (60
), stirring (200 rpm) for 6 h, or sonication in 42 kHz ultrasonic bath for 15, 30 and 45 minutes. Contents of 20-hydroxyecdysone (20E) and ponasterone A (PonA) were measured by using HPLC after purification of the extracts by
cartridge. Altogether, our results indicate that the extraction using sonication with MeOH as a solvent (for 30 minutes) was the most effective condition for 20E and PonA from both MFS and FOJ. Resulting contents of 20E from FMS and FOJ were 66.76 and 104.48
and PonA were 53.43 and 43.82

DOI : 10.7732/kjpr.2011.24.4.358
The internal transcribed spacer (ITS) regions of nuclear ribosomal DNA from genus Chrysosplenium were sequenced to address phylogenetic relationship. ITS including 5.8S sequence varied in length from 647 bp to 653 bp. Among them, 219 sites were variable sites with parsimony-informative. The aligned sequences were analyzed by maximum parsimony (MP) and neighbor-joining (NJ) methods. In the strict consensus trees of parsimony analysis, the monophyly of Chrysosplenium was supported by 100% bootstrap value. The first clade, C. pseudofauriei was at the basal position of the genus, and others formed two clades with high bootstrap support. The second clade included Ser. Pilosa and Ser. Oppositifolia and third clade included Ser. Alternifolia and Ser. Flagellifera. The NJ trees showed essentially the same topology. Finally, DNA sequences of ITS regions were useful phylogenetic marker in this genus. Based on the ITS and ridge seed morphological results, C. sphaerospermum Maxim. and C. valdepilosum (Ohwi) S.H. Kang & J.W. Han were discussed their scientific names and taxonomic positions.

To address infra-specific relationships of Sedum kamtschaticum Fisch., and to provide the fundamental information for developing new horticultural variations, we analyzed the morphology of individuals in four natural populations (Mt. Gwangdeok, Mt. Samyeong, Mt. Yonghwa, Tongyeong) and investigated the vegetations of these area. Based on 50 morphological characters the principle component analysis (PCA) has been performed. Principle component axis 1, 2, and 3 explain 22.9%, 14.2%, and 7.4% of total variations, respectively. Dot plot of OTUs in PC2 by PC1 area showed that the areas of four populations are completely overlapped. The result of PCA and the statistics of each character indicate that all of morphological characters are overlapped in these four populations. The maximum deviations are found in the characters related in the size and shape of the leaf. In the vegetation analyses, eighteen community plots that we investigated were grouped into 10 subcommunities: subcomm. Boehmeria spicata, subcomm. Artemisia stolonifera, subcomm. Artemisia keiskeana, subcomm. Impatiens nolitangere, subcomm. Crepidiastrum chelidoniifolium, subcomm. Urtica thunbergiana, subcomm. Artemisia gmelini, subcomm. Commelina communis, subcomm. Erigeron annuus-Artemisia princeps, and typical subcommunity.

Korean Journal of Plant Resources, volume 24, issue 4, 2011, Pages 395~403
DOI : 10.7732/kjpr.2011.24.4.395
This study was conducted to investigate the habitat positional environment and vegetation properties of Mankyua chejuense. The habitats were classified into two types depending on the depth of the habitat, the ratio of rock exposure, the dominant species and the surrounding vegetation, which affected the vegetation of the habitats. The habitats with a high ratio of rock exposure showed a distinctive geographical boundary to the adjacent region and most of them were composed of trees that grow in humid environment. On the contrary, in the soil-rich habitats, the depth was shallow, soil layer was well developed, and the trees were introduced from the adjacent areas. However, the dominant species in the herbaceous layer were aquatic plants, which indicated that the habitats had the properties of wetland. Therefore, it was found that thes habitats of Mankyua chejuense have the properties similar to those of marshland. For the preservation of Mankyua chejuense, it is very important to make the habitats maintain such properties of wetland.

DOI : 10.7732/kjpr.2011.24.4.404
This study was carried out to compare and analyze the active ingredients of Korean native ginger and rhizome derived from in vitro shoot-tip culture of Korean native ginger. Proximate compositions, mineral nutrients, free sugars, fatty acids, volatile components, 6-gingerol, and 6-shogaol were analysed and evaluated. Korean native ginger was proved to have a little more contents than in vitro rhizome in proximate compositions (crude ash, crude lipid, crude protein, carbohydrate). Mineral nutrient contents (Cu, Fe, Mn, Zn) of in vitro rhizome were higher than those of Korean native ginger. Among the mineral nutrients, the quantity of K was the highest, followed by P, Mg, Na, and Ca. Free sugar contents (fructose, glucose, sucrose) of in vitro rhizome were higher than those of Korean native ginger. Fatty acids containing less than C14 was the major among the fatty acids in ginger. Citral ingredient of the unique aromatic compound of Korean native ginger was stronger than that of the rhizome derived from in vitro shoot-tip culture. Gingerol concentration was increased by shoot-tip culture.

DOI : 10.7732/kjpr.2011.24.4.413
This study was carried out to establish a proper cultivation site and diagnose the drought-tolerance of Aster scaber and Synurus deltoides leaves by using Pressure-volume curves. In order to measure pressure-volume (P-V) curves, Aster scaber and Synurus deltoides were cut off above ground part and the tip of the cutting were placed in water, which was covered with a plastic bag. Samples were kept overnight (about 12 hours) in darkness at room temperature (20~25
) to achieve maximal turgor (full saturation). The pressure in the chamber was gradually increased from 0.3MPa to 1.8MPa by nitrogen gas. After measured, leaf samples were dried at 80
for 48 hours and dry weight of each samples were determined. The result of the original bulk osmotic potential at maximum turgor
sat was lower -0.8 MPa in Aster scaber leaves than -0.7 MPa Synurus deltoides leaves. Also the osmotic potential at incipient plasmolysis
in Aster scaber leave was -0.9 MPa. In contrast, the value of maximum bulk modulus of elasticity
of Aster scaber leaves were approximately two folds higher than that of Synurus deltoides leaves. The values of the relative water content at incipient plasmolysis
are all above 90% showing that the function of osmoregulation is somewhat better, and Vo/DW, Vt/DW, Ns/DW of Synurus deltoides leaves were approximately 1~2 times higher than that of Aster scaber leaves. Thus, responses to water relations of Aster scaber and Synurus deltoides such as
were shown that the Aster scaber leaves was slightly higher drought-tolerance than Synurus deltoides leaves. However, in both of Aster scaber and Synurus deltoides, occurring incipient plasmolysis at the high water content, have a relatively lower drought-tolerance property indicating that growth of these plants are cultivated appropriate in high moisture soil sites.

Korean Journal of Plant Resources, volume 24, issue 4, 2011, Pages 430~437
DOI : 10.7732/kjpr.2011.24.4.430
The epidermal recovering-effects of the Cnidium officinale extract after inducing contact-dermatitis by 1-chloro-2,4-dinitrochlorobenzene (DNCB) showed by measuring thickness of skin, identifying IgE amounts in plasma, and activities of anti-oxidant enzymes using histochemical and biochemical methods. By three-time applications of the extract, morphological changes of dermatitis in impaired region were recovered dramatically and shape of skin surface and thickness of epidermis were restored to be normal. Also, lipid content was recovered to the level of normal state. We suggested that extract treatment lowered a hypersensitive reaction by decreasing of IgE level in blood and restored activities of superoxide dismutase and catalase. In conclusion, we proposed that C. officinale extract might be used as natural resources for treating effectively allergic contact-dermatitis.

DOI : 10.7732/kjpr.2011.24.4.438
This study was conducted to investigate temperature effect on seed germination behaviors and seed viability changes by drying periods of three Ulmus species (Ulmus davidiana var. japonica (Rehder) Nakai, U. pumila L., and U. parvifolia Jacq.) distributed in Korea. Statistical analysis showed that temperature had a significant effect on mean germination time in three Ulmus species, but its effect on germination percentage was only shown in U. parvifolia (p<0.01). U. davidiana var. japonica and U. pumila germinated relatively consistent in all temperature conditions, especially the latter showed high germination behaviors in low temperatures (10-15
). U. parvifolia germinated well in high temperature (25
), while this species rarely germinated in low temperature conditions (10-20
). The results confirm that seeds of U. pumila and U. parvifolia are orthodox seeds which can be stored under 4-8% moisture condition, and U. davidiana var. japonica seed is recalcitrant seed which is difficult to store for a long time. In conclusion, these differences of the germination behaviors for three Ulmus species seem to be adaptive regimes of their natural habitats, respectively.
Effect of Moss (Hypnum jutlandicum) Extracts and Mixing Treatments with Preservatives on Vase Life of Rosa hybrida `Enjoy`
Park, Kyoung-Hee ; Shin, So-Lim ; Lee, Cheol-Hee ;
Korean Journal of Plant Resources, volume 24, issue 4, 2011, Pages 445~455
DOI : 10.7732/kjpr.2011.24.4.445
This study was performed to develop a natural preservative which had the most successful effect on prolonging the vase life of cut flowers Rosa hybrida `Enjoy`. To determine the effect of sucrose on vase life of cut roses, R. hybrida `Enjoy`, 0, 1, 3 or 5% of sucrose was mixed with Hypnum jutlandicum extract. The result showed that in the case of adding sucrose to extracts from H. jutlandicum, vase life of cut flowers was shortened, along with the cut flowers losing chlorophyll, becoming decolorized and finally showing wilting phenomenon. However, using hydroxy quinoline sulfate (HQS) and extracts from H. jutlandicum together exhibited an improved effect of prolonging vase life, especially when adding 100
HQS, which had the effect of prolonging the vase life of R. hybrida `Enjoy` the most. Regarding pH of extracts, 2
of extracts from H. jutlandicum show originally pH 3.8. This was compared with adjusted extract solutions as pH 3.0, 4.0 or 5.0. The results showed that the solution of pH 3.8 had the most successful effect on prolonging the vase life of R. hybrida `Enjoy`. Given all the results, H. jutlandicum extract (2
) and HQS (100
) was the most effective in prolonging the vase life of cut R. hybrida `Enjoy`. Moss is expected to be worth developing as a natural preservative since it is easy to get and causes no damage to the environment.

DOI : 10.7732/kjpr.2011.24.4.456
The objective of this study was to investigate the antioxidative capacity of Rhododendron brachycarpum 95% ethanol extracts. Total antioxidant status was examined by total antioxidant capacity against ABTS radical reactions. Total antioxidant capacities of R. brachycarpum extract at the concentrations of 0.2 and 1 mg/mL were 0.33 and 2.26 mM Trolox equivalents, respectively. Superoxide scavenging activities of R. brachycarpum extract at the concentrations of 0.2 and 1 mg/mL were 45.0 and 77.0%, respectively. Oxygen radical absorbance capacities of R. brachycarpum extract at the concentrations of 5 and 100
were 40.88 and 131.00
Trolox equivalents, respectively. Total phenolic contents of R. brachycarpum extract at the concentrations of 0.2 and 1 mg/mL were 0.37 and 1.25 mM gallic acid equivalents, respectively. R. brachycarpum extract at the concentration of 0.1 mg/mL inhibited 0.2 mM and 0.5 mM tert-butyl hydroperoxide induced cyototoxicity by 52.1 and 30.3%, respectively, in HepG2 cell culture system. Thus, strong antioxidant and cytotoxicity-inhibiting effects of R. brachycarpum extract seem to be due to, at least in part, the prevention from free radicals-induced oxidation as well as high levels in total phenolic contents.

This study was carried out to establish an in vitro culture method of callus having a high antioxidant activity from Ginkgo biloba L. Leaf explants were cultured on Murashige and Skoog`s medium supplemented with various growth regulators. The explants were incubated in the dark or 3,000 lux cool-white light. Methanol extracts from incubated callus were evaluated for scavenging activity of the free radicals using DPPH. The best callus growth rate was achieved in MS medium combined with 10
NAA and 5
kinetin in the light condition. Total antioxidant activity of cell aggregates in suspension culture [MS medium supplemented with 10
NAA in the light] was up to 80% of ascorbic acid. By means of HPLC analysis, quantification of the quercetin dehydrate and keamperol profiles from suspension callus was compared. Contents of quercetin dehydrate and keamperol from leaf extracts were 0.07 and 2.24
, and those from callus 0.56 and 0.18

In order to reuse remnants of medicinal herb extracts as an environment-friendly manure, fermented compost made from medicinal herb waste (MHWC), poultry manure compost (PMC) and MHWC+PMC (1:1, w/w) were applied on upland soil cultivated with 2 year-old Bokbunja plants. The results of the changes of soil chemical properties on upland soil, the yield and the sugar contents of the fruit harvested were summarized as follows. The pH in soils treated with composts (STCs) was significantly changed (p<0.05) compared with untreated control (UC) group. The electrical conductivity (EC) in MHWC group was decreased 0.46-0.56 times compared with UC, and it was different from PMC groups. The contents of organic matter and total nitrogen were increased in all of the treatments and MHWC group was the highest among the all groups. The content of available phosphorous was different by types and amounts of the composts. The content of heavy metal in all groups did not exceed the standard content for soil contamination. The yield and the sugar contents of the fruit harvested were the highest in the treatments of MHWC. In conclusion, MHWC is an effective compost resource on improvement of soil environment and promoting the fruit qualities.
