Influence of Applied Pressure and Heat Treatment on Antioxidant Activities of Young Leaves from Achillea alpina and Solidago virgaurea subsp. gigantea
Woo, Jeong-Hyang ; Shin, So-Lim ; Jeong, Heon-Sang ; Lee, Cheol-Hee ;
Korean Journal of Plant Resources, volume 23, issue 2, 2010, Pages 123~130
Present studies were conducted to investigate the effects of autoclaving on antioxidant activities of Achillea alpina and Solodago virgurea. At early April, young leaves of 2 species were collected, subjected to autoclaving (
, 1.2 atmospheric pressure, 15 minutes), freezed-dried, grinded, and extracted with 80% ethanol. The same process was repeated with unautoclaved control. Total polyphenol and flavonoid contents, scavenging activities on DPPH and ABTS radicals and ferrous ion chelating effects were analyzed. Extraction yield of autoclaved S. virgurea was 39.55% and A. alpina 28.15%. In both species, autoclaving significantly reduced scavenging activities on DPPH and ABTS radicals. On the contrary, ferrous ion chelating effects increased after autoclaving, especially in young leaves of A. alpina. Autoclaving resulted in decrease of polyphenol and flavonoid contents, especially in the A. alpina. The present experiments demonstrated that autoclaving had negative effects on antioxidant activities of A. alpina and S. virgurea, except in ferrous ion chelating effects. Young leaves of former species were unstable to heat treatment, resulting in big lose of antioxidant activity.

Tartary buckwheat has potential as a source of functional food because it contains a number of bioactive compounds such as rutin, catechin and so on. This study was conducted to determine the possibility of development of processed products extracted from sugar-treated sprouts of tartary buckwheat. By using undiluted solution extracted from sprouts of tartary buckwheat, we analyzed their nutrition components and did in vivo experiment to find out pharmaceutical effects. In an experiment using mice, we administered various concentration of buckwheat to induced diabetic mellitus mice for 1 weeks. As a result, the fermented extract from buckwheat sprouts effected finely on lowering blood sugar and decreased LDL-cholesterol and total lipid level but increased HDL-cholesterol level.
Effect of Medicinal Herbs Remnant Used as Fertilizer on Major Agronomic Characteristics and Yield of Agastache rugosa
Choi, Seong-Kyu ;
Korean Journal of Plant Resources, volume 23, issue 2, 2010, Pages 138~144
This study was carried out to examine used as fertilizer on growth and yield of Gastache rugosa. The medicinal herbs('Yeonryeonggobondan') remnant which have prescriptions of high frequency by Korean was analyzed. The medicinal herbs remnant have high content of nitrogen, phosphoric acid, potassium and organic. The growth of Agastache rugosa by application of medicinal herbs remnants were more effective than that of control. As the amount of fertilizers were increased, plant height, stem diameter, number of leaves and number of branches were increased. The growth was the highest in the treatment of 30~50 g/pot. Weight of whole plant of Agastache rugosa has a tendency to be heavy in application of medicinal herbs remnant than that of control.

To examine the antioxidative effect and melanogenesis of Nelumbo nucifera stamen (NNS) extract on hydrogen peroxide
induced cytotoxicity in cultured human skin melanoma cells (SK-MEL-3), cell adhesion activity (CAA), tyrosinase inhibitory activity and total amount of melanin synthesis were measured by colorimetric assay. In this study,
significantly decreased CAA, and
was determined at 30 uM. In the antioxidative effect, NNS extract increased cell adhesion activity which was decreased by
induced cytotoxicity, and also, tyrosinase activity and total amount of melanin were decreased by NNS extract. These results suggested that
was highly toxic on cultured human skin melanoma cells and NNS extract showed the antioxidative and inhibitory effect of melanogenesis by the increased CAA, and the decresed tyrosinase activity and total amount of melanin synthesis.

Alginates are polysaccharides isolated from brown algae with gel-forming properties composed of 1,4-linked beta-D-mannuronic acid (M), alpha-L-guluronic acid (G), and alternating (MG) blocks. In this study, we have examined the toxic effects of high M-alginate to activate HepG2 human liver cells. Alginate enhanced the NO production and iNOS protein expression in HepG2 cells. In addition, alginates stimulated the HepG2 to induce IL-1 release and expression of TGF-beta1, which could influence the liver inflammation and chirrhosis. These findings suggest that high M-alginate form brown algae may have toxic effects on liver cells.

Rosa rugosa has been used as a folk medicine with various pharmacological properties for a long time in Asia. We investigated effects of fructus extracts of Rosa rugosa (RRF) and semen extracts of this herb (RRS) on bone forming cells (osteoblastic and pre-osteoclastic cells) to evaluate the pharmacological possibilities in a variety of bone-related disease. RRF showed significant effect on proliferation of osteoblastic cells in dose-dependent manners at 72 hrs and
of RRS was effective at 48 and 72 hrs. RRF and RRS did not decreased production of TNF-
but NO by pre-osteoclastic cells under inflammation circumstance indeced by LPS. We also investigated the effects of RRF and RRS on the mitogen-induced lymphocyte proliferation in the old and young mice in ex vivo systems. RRF and RRS significantly enhanced proliferative effects of untreated and ConA-treated splenocytes from the old and young mice. But, RRS at
increased LPS-induced TNF-
production in pre-osteoclastic cells and reduced LPS-stimulated lymphoblastogenesis in the old and young at
. These results indicate that RRF has beneficial effects on osteoarthritis and give further possibilities for the immunomodulating effects not only in old that has more frequent bone related diseases but also in young.

Oxidative stress induced by reactive oxygen intermediates has been implicated in a variety of human diseases including neurodegenerative disorders, cancer, cardiovascular and respiratory diseases, and mode of action of environmental toxicants. Tert-butylhydroperoxide (t-BHP) is an organic lipid hydroperoxide analogue, which is commonly used as a pro-oxidant for evaluating mechanisms involving oxidative stress in cells and tissues. In this study, the underlying mechanisms involved in the protective effects of Hwabuk 94 kiwifruit (Actinidia deliciosa cv. 'Hwabuk 94'), which is cultivated in Jeju, on the t-BHP-induced cytotoxicity in PC12 cell. The pretreatment of rat pheochromocytoma cell line PC12 with Hwabuk 94 extract (
) resulted in a significant recovery from t-BHP-induced cell death and increased Bcl-2 and procaspase-3 expression, whereas the expression of Bax and cleaved PARP were decreased in a dose-dependent manner compared to the control. Furthermore, Hwabuk 94 inhibited the t-BHP-induced p38 MAP kinase and extracellular signal-regulated kinase 1/2, but not c-Jun N-terminal kinase activations. Finally, these findings suggest that Hwabuk 94 kiwifruit might attenuate t-BHP-induced PC12 cell cytotoxicity, at least in part, through the inhibition of signaling pathways mediated by the ERK1/2 and p38 MAP kinase.

Jung, Myung-Suk ; Hyun, Jung-Oh ; Lee, Uk ; Baik, Eul-Sun ;
Korean Journal of Plant Resources, volume 23, issue 2, 2010, Pages 172~178
This study was carried out to investigate abiotic and biotic environmental factors affecting homoharringtonine (HHT) contents of Cephalotaxus koreana, whereby, to provide basic information of high value-added industry production of HHT as a promising anti-cancer agent. For correlation between abiotic environmental factors (soil moisture, soil pH, habitat density and temperature) and HHT contents, the contents were highly correlated with soil moisture (0.77) and soil pH (-0.68). For multiple regression analysis of relationship between abiotic environmental factors (soil moisture and soil pH) and HHT contents, soil moisture appeared to be strongly affecting the contents relatively due to being significant at only its regression coefficient (
). For the effect of biotic environmental factors (damage index) affecting HHT contents, the contents was quadratic with equation of
, also, damage index had strong effect on the contents. Finally, for the result of the most influencing an environmental factor on HHT contents, both damage index and soil moisture were suitable in second polynomial regression, also, damage index (
) was turned out to be more influencing factor than soil moisture (
) on HHT contents relatively. Therefore, we predict that HHT contents in the trees of Cephalotaxus koreana is produced as a chemical defense mechanism triggered by a stress-related damage of fungi or insects.

This study was conducted to provide basic information for conservation and restoration through investigation of vegetation and soil condition of Megaleranthis saniculifolia Ohwi, Korean endemic species, in Mt. Halla, Jeju Island. Very few individuals were discontinuously distributed and restricted at 1,075 m above sea level, very steep slope (
), rocky area of north face of Eorimok Valley. For investigation of environmental condition, we established two
quadrats in the habitats and one control quadrat. Twenty-four species were found at site 1 under 10-12 m Carpinus laxiflora tree layer (35%) and soil conditions are pH 5.9, moisture content (field capacity) 9.39%, organic carbon 8.22% and organic matter 14.17%, respectively. Site2, 15 taxa were found under 8-12 m Platycarya strobilacea tree layer (40%) and soil conditions are pH 5.07, moisture content 4.99%, organic carbon 5.34% and 9.21 percentage of organic matter. In the control quadrat, 14 taxa were found under 10 m Carpinus laxiflora tree layer (10%) and soil conditions are pH 5.27, moisture content 6.23%, organic carbon 4.74% and organic matter 8.17%, respectively. The principal causes of threat which were investigated in this study are competition among company, very steep slopes, artificial management of valley. For restoration and conservation of habitats, it is needed to suitable plans.

Korean Journal of Plant Resources, volume 23, issue 2, 2010, Pages 187~196
A total of 10 islands (Kumodo and Komundo in Yeosu City; Oinarodo in Goheung County; Chongsando, Soando, and Pogildo in Wando County; Chodo in Jindo County; Uido, Huksando, and Hongdo in Shinan County) were surveyed to confirm distribution of naturalized plants from June 2006 to December 2008. A total of 100 naturalized plants taxa from 25 families were recorded. The highest number of naturalized plant species (82 taxa) was recorded on Oinarodo, while the lowest number was recorded on Hongdo (42 taxa) and on Uido (34 taxa). A total of 26 naturalized species taxa (such as Dactylis glomerata, Lolium perenne, Bromus unioloides, Rumex obtusifolius, Chenopodium album, Phytolacca americana, Barbarea vulgaris, Lepidium apetalum, Robinia pseudo-acacia, Trifolium repens, Erigeron annuus, Erigeron canadensis, Senecio vulgaris, Xanthium strumarium) was recorded in all study areas. Distribution of naturalized plants were categorized into 7 habitat types based on ecological traits: afforested land, beach, port, and vacant land, road boundary, road cut and slope area, waste arable land, landfill area, and wetland. Systematic management is required to conserve unique landscape, species diversity, vegetation and ecosystem of Dadohae National Park. In order to manage the naturalized plants in Dadohae National Park, basic surveys are most needed to understand distribution and dispersal of naturalized plants communities based on ecological features of each habitat type.

Korean Journal of Plant Resources, volume 23, issue 2, 2010, Pages 197~205
This study was carried out to investigate the flora and vegetation in wetland of Mueuido. The forest vegetation was classified into 2 communities group (Utricularia bifida-Eriocaulon sikokianum and Alnus japonica) and 6 communities (Rhynchospora chinensis, Phragmites communis, Molinia japonica, Ischaemum crassipes, Quercus serrata and Pinus rigida-Miscanthus sinesis). Resources vascular plants were composed of 30 families, 53 genera, 50 species and 8 varieties, totaling 58 taxa. Among the investigated resources plants, Utricularia bifida and Utricularia racemosa were rare and endangered species. The special plants based on floral region by Ministry of Environment were 5 taxa; V rank species 2 taxa, II rank species 1 taxa and I rank species 2 taxa. A naturalized plants was 1 species of totaling 290 species appeared in South Korea. The Life-form were Hydatophytes (20.7%), Geophyte (19%), Microphanerophytes (19%), Hemicryptophytes (17.2%), Nanophanerophytes (17.2%), Chamaephytes (5.2%), Therophytes (1.7%). In marsh-type wetland of Mueuido, we predict that bog-type swamp, where various type of swamp plants are distributed, is starting to be formed based on the fact that Utricularia bifida and Utricularia racemosa, insectivorous plants, are dominant and sphagnum also is found. Along with the notion, there are reportedly found serious damages around wetland by human being and we have to prepare protection plans against it.
