  • In this study, the vascular plants of the Mt. Deokhangsan protected area were surveyed for the purpose of forest genetic resources conservation in Gangwon-do, South Korea. The flora on Mt. Deokhangsan were classified as follows 537 taxa, 90 families, 302 genera, 479 species, 4 subspecies, 51 varieties, and 3 forms. Among the taxa, 19 were Korean endemic plants and 17 were rare and endangered plants. Plants as indicators of limestone areas were found in 33 taxa. Naturalized plants were found in 27 taxa and species threatened by climate change were found in 33 taxa, including 11 endemic plant taxa and 22 northern plant taxa. Plants endemic to Korea and northern plants were mainly found at the study site, whereas southern plants were not found. Thus, Mt. Deokhangsan apparently has an environment suitable for the growth of northern plants.

  • This study was carried out to investigate the flora of Is. Gageo (Jeollanam-do). The vascular plants were collected 13 times (from June 2008 to September 2011), and 465 taxa in total were identified, including 112 families, 301 genera, 402 species, 3 subspecies, 49 varieties, 9 forms and 2 hybrids. 171 taxa were first records for the region. Among them were seven taxa of Korean endemic plants and the Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as three taxa. There were 54 taxa of the flora with the levels III, IV, V in the floristic indicator plants which was designated by Ministry of Environment. The naturalized plants were identified as 29 taxa, and their naturalization ratio and urban index were found to be 6.2% and 9.0% respectively. There existed many kinds of plants resources having conservational value like $Loxogramme$ $salicifolia$, $Sarcandra$ $glabra$, $Osmanthus$ $insularis$, $Saussurea$ $polylepis$, $Carex$ $ligulata$ var. $austrokoreensis$, $Hosta$ $jonesii$, $Cyrtosia$ $septentrionalis$, etc., in this area. As therefore clear that appropriate plans to conserve the natural habitat of Is. Gageo must be made immediately.

  • The present study, antioxidant and anti-inflammatory effects were measured of 6 endemic plants in Indonesian extracted by hot water or ethanol. The Nipa Fruticans Wurmb ethanol extract (NFWE) and Orthosiphon aristatus ethanol extract (OAE) showed the highest polyphenol and flavonoid contents of 203.70 and 33.70 ㎍/mg, respectively. Antioxidant activity of OAE was highest in DPPH radical scavenging activity (77.49% at 10 ㎍/mL) and ABTS+ radical scavenging activity (93.36% at 10 ㎍/mL). FRAP activity was significantly higher in NFWE than other extracts. Anti-inflammatory effects of 6 endemic plants in Indonesian extracted by hot water or ethanol were examined using nitric oxide (NO) inhibition assays. In the LPS-induced BV2 cells, OAE showed the highest inhibition of NO production without toxicity. The results of this study, suggest that OAE is a potential functional raw material for antioxidant and anti-inflammatory.
