The present study was carried out to evaluate biologically active components of the rhizomes of Sparganium stoloniferum and to supply the preliminary data for the chemotaxonomy and the medicinal application. Extraction and systematic fractionation of the rhizomes by column chromatography led to the isolation of six compounds from ethylacetate and n-butanol soluble fractions. Elucidation of the chemical structures of these compounds by physicochemical and apectral analysis demonstrated that compound I,II ,III,IV,V and Ⅵ were $\beta$-sitosterol, $\beta$-sitosterol-3-$\beta$-D-glucuronopyranoside, 3- (4-hydroxyphenyl)-2-propenoic acid, sorbose, 1-O-$\beta$-D-glucopyranosyl-(2S, 3R, 4E, 8Z)-2-[(2(R)-hydroxyeicosanoyl)amido]-4,8-octadecadiene-1,3-diol, and $\beta$-sitosterol-3-O-$\beta$-D-glucopyranoside, respectively.

Three compounds, vanillic acid, p-hydroxylcinnamic acid, p-hydroxybenzaldehyde have been isolated from the ethylacetate extract of Sparganium stoloniferum Buch.-Ham roots using silica gel open column chromatography, preparative thin-layer chromatography (pTLC) and reverse phase high performance liquid chromatography. The structures of the compounds were established on the basis of IR, extensive 1D NMR, and MS analyses. The ethylacetate (EtOAc) extract, vanillic acid, and p-hydroxybenzaldehyde showed $\alpha$-glucosidase inhibition activity of 72.71%, 20.13%, and 30.42%, at the concentration of 10 ${\mu}g/mL$, respectively. The EtOAc extract exhibited strong antioxidant activity with an $IC_50$ value of 24.37 ${\mu}g/mL$ against DPPH radical scavenging activity, the vanillic acid, p-hydroxylcinnamic acid, and p-hydroxybenzaldehyde with an $IC_50$ value of 2.10 ${\mu}M$, 1.59 ${\mu}M$, and 2.72 ${\mu}M$ against DPPH, respectively.

Sparganium stoloniferum Buch.-Ham. (Sparganiaceae) is a perennial herb which has been used as treatments for menstrual disorder, galactagogue and endometriosis in folk remedies. The Sparganii Rhizoma processed, heated with vinegar, used to different purpose compared with origin in medicine. In order to estimate the different effects between processed (PSR) and unprocessed (USR) Sparganii Rhizoma, extraction and systemic fractionation of the rhizomes were archived. Inhibitory effects of the extracts as well as the fractions of PSR and USR on rat lens aldose reductase and on rat platelet aggregation were investigated for the prevention or the treatment of chronic diabetic complications. Their antioxidant effects, measured using lipid peroxidation of liver tissue and radical scavenging activities on 1,1-diphenyl-picrylhydrazyl in vitro, were evaluated. The most of biological activities tested except rat platelet aggregation, fractions from PSR were shown to exhibit stronger activities than those from USR. It seems that caused by changing of the chemical components by heating process in conditioned with acetic acid. Compounds isolated were shown to significant inhibitory activity on rat lens aldose reductase. Inhibitory activity of compounds isolated on rat lens aldose reductase have been tested in vitro. $IC_{50}$/ (6.31 $\mu$M) of cerebroside I (V) was nearly equal to that (6.32 $\mu$M) of a reference compound, tetrametbylene glutaric acid (TMG).

Two unrecognized species of Sparganium of Korea were found during the our field expeditions and phylogenetic analyses of specimens deposited in the Herbarium of Korea National Arboretum (KH). S. coreanum H. $L{\acute{e}}v$. was first reported as a new species based on the specimen (Taquet, 2150) collected from Jeju Island. It has been recognized as synonym or infraspecific taxa of S. stoloniferum and S. eurycarpum or even never recognized recently. However, phylogenetic tree showed that S. coreanum is monophyletic and has sister relationship with S. eurycarpum. Furthermore, additional distribution localities were also found by herbarium survey. Morphological characteristics and distribution information of S. coreanum will be discussed. Another Sparganium species found from Mt. Daeam is occurring either as floating or emergent. Although we could not identify this species since lack of any flowers or fruits for two year surveys, phylogenetic analyses results showed that this species belong to the clade of S. glomeratum, which is distributed in high elevation lakes and marshes of Europe, Asia, and North America. Additional survey of morphology and report will be needed.

The anti-diabetic effect of Cirsium setidens water extract and the combinations with Bletilla striata, Cymbidium kanran, and Sparganium stoloniferum Buch.-Ham. ethanolic extracts had been studied. The combination of four extracts (3:1:1:1) showed larger anti-diabetic activity in vitro and in vivo. It is notable that the single water extract from C. setidens exhibited more effective anti-diabetic effect than most of the combinations. We also investigated whether fermentation process was promoted the anti-diabetic activity. The data suggested the fermentation product of combination of four extracts (3:1:1:1) exhibited the strongest activity both in vitro and in vivo, which was higher than the non-fermented group. The result indicated the fermentation and the appropriate combination of extracts enhanced the anti-diabetes activity.

The purpose of this study was to create an artificial wetland in rooftop greening. We monitored species and changes of flora in wetland and rooftop greening. As shown the consideration and possibility of supplying the artificial wetland in rooftop greening through flora in wetland, this study tried to find methods to create a efficient flora space. This results are listed as belows. The species were applied to artificial wetland in rooftop greening and come up to 'General standard for selecting plants' among hydrophyte in wetlands. The plants of Potentilla kleiniana, Penthorum chinense, Scirpus radicans, Scirpus triqueter, Veronica undulata, Mentha arvensis var. piperascens, Salvia plebeian, Sagittaria aginashi, Aneilema keisak, Stachys riederi, Alisma canaliculatum, Eclipta prostrata, Sparganium stoloniferum turned out an appropriate species. This research was expected to create a various environment and component of species by introducing many types of plants in ecological wetland on rooftop greening.

Wetlands of Dongbaekdongsan were classified into two types of pond and vernal pool. 11 plant communities are established there such as Nymphoides indica community, Sparganium stoloniferum Community, Persicaria hastato-auriculata community, Scirpus triangulatus community, Triadenum japonica community, Juncus papillosus community, Deinostema violacea community, Centipeda minima community, Apocynum sibiricum community, Isachne globosa community, and Ulmus parvifolia community. Nymphoides indica community is established in a pond located on the entrance of the Dongbaekdongsan and Persicaria hastatoauriculata community appears on edge of the pond. Sparganium stoloniferum community is formed in nearby pond with relatively shallow water and Persicaria hastatoauriculata community is established on margin of the pond. Vernal pools had been used for drinking water source and for livestock in some cases in the past. Scirpus triangulatus community is established in the most wet site as the center of the pools and Juncus papillosus community - Deinostema violacea community - Triadenum japonica community, and Apocynum sibiricum community appear in a concentric circle pattern as far away there. Ulmus parvifolia community is established in a dry vernal pool. This is the first study on vernal pool carried out in Korea. Therefore, most vegetation types are new ones different from existing studies on wetland.

This study aims to find out the growth characteristics of riparian plants on the artificial floating islands (AFI). Three types of experiments were performed. The vegetation growth were compared by the plant-supporting materials; natural cotton mat, coir mat on the AFI or in the water, and natural soil at the waterfront. Major findings are; 1. The survival rate of riparian plants was 100% on both coir-mat and cotton-matislands, which implies that we may substitute cheaper cotton for expensive coir-mat. 2. Both natural cotton mat and coir mat were good for the growth of plants. Especially, the natural cotton mat was good for Sparganium stoloniferum and Miscanthus sacchariflorus, and the coir mat was good for Typha latifolia. 3. The growth rate of stem and root showed difference between the stem-removed plants and stem-remaining plants. As a whole, the growth rate of stem-removed plants was bigger than the one of stem-remaining plants. 4. The growth rate of plants showed difference between those grown on the AFI and those grown in the water. The growth rate of plant on the AFI was bigger than the one in the water. 5. The growth rate of plants on the AFI was bigger than the one on the natural soil at the waterfront.
