  • Acanthopanax divaricatus var. albeofructus is one of the indigenous medicinal plant and the fruits of Acanthopanax spp. used as a remedial for "wipe out evil wind". Two anthocyanin were isolated from the fruits of Acanthopanax divaricatus var. albeofructus. Their structures were elucidated as cyanidin 3-lathyroside (1) and cyanidin 3-galactoside (2) by chemicophysical and spectroscopic analysis. And also, four chemical, syringin, chlorogenic acid, caffeic acid and acanthoside D were identified. Both anthocyanide were isolated for the first time from Acanthopanax species. cyanidin 3-lathyroside is one of the rare anthocyanin in natural resources.

  • Acanthopanax species (Araliaceae) has been traditionally used as analgesics, stimulants of immune system, and replenishment of body functions. Acanthopanax divaricatus var. albeofructus is a indigenous plant in Korea. The anti-lipid peroxidation activities of the loaves and root bark extracts of A divaricatus var. albeofructus were determined. Activities of MeOH extracts were examined in vitro and in vivo with control group intoxicated by carbon tetrachloride. Both extracts showed significant inhibitory effects on the lipid peroxidation.

  • Phytochemical examination of the leaves of Alnus hirsuta, one of the indigenous species grows in Korea, has led to the isolation of one flavan 3-ol and two flavonol glycosides. Structures of these compounds are identified as (-)-epicatechin (1), quercetin $3-O-{\beta}-D-galactopyranoside$ (2), quercetin $3-O-{\beta}-D-galactopyranoside$ (3) by means of physico-chemical and spectral evidences.

  • As a subset study to discover indigenous prokaryotic species in Korea, a total of 29 bacterial strains assigned to the classes Alphaproteobacteria were isolated from various environmental samples collected from plant root, ginseng soil, forest soil, marsh, mud flat, freshwater and seawater. From the high 16S rRNA gene sequence similarity (>99.1%) and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to each independent and predefined bacterial species. There is no official report that these 29 species included in Alphaproteobacteria is have been described in Korea; therefore 14 species of 9 genera in the order Rhizobiales, 7 species of 6 genera in the order Sphingomonadales and 4 species of 2 genera in the order Caulobacterales and 3 species in the order Rhodobacterales and 1 species in the order Rhodospirillales found in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are also described in the species description section.

  • As a result of the research project 'Survey and excavation of Korean indigenous species' to secure unrecorded species in Korea, a total of 14 unreported bacterial strains assigned to the phyla Deinococcus-Thermus and Bacteroidetes were isolated from various environmental habitats all around Korea. On the basis of 16S rRNA gene sequence similarity and affiliation to the clade with the closest species, it was concluded that the isolates represent deep groups of the phyla Deinococcus-Thermus and Bacteroidetes. There have been no records about these 14 unreported species in Korea; therefore 2 species of 2 genera in the class Deinococci within the phylum Deinococcus-Thermus, and 11 species of 9 genera in the class Flavobacteriia and one species in one genus in the class Sphigobacteriia within the phylum Bacteroidetes are described as unreported species found in Korea. Gram staining reaction, morphological and other biochemical characteristics are described in the species description section.

  • In 2016, as a part of the research program 'Survey of Korean Indigenous Species', diverse environmental samples were collected from various sources of freshwater, seawater, soil, wetland, reclaimed land, sand, pine forest, plant root, ginseng field, solar saltern, and caves. Thousands of bacterial strains were isolated from the diverse samples and identified based on 16S rRNA gene sequence analyses. The present study, as a phylogenetic subset of the primary research program, reports 24 unrecorded bacterial species in Korea that belong to the orders Rhizobiales and Sphingomonadales in the class Alphaproteobacteria. Based on the high 16S rRNA gene sequence similarities (>98.8%) and formation of a robust phylogenetic clade with the closest type species, it was determined that each strain belonged to each independent and predefined bacterial species. There is no official report that these 24 bacterial species have been described in Korea; therefore, 10 species of nine genera in the order Rhizobiales and 14 species of seven genera in the order Sphingomonadales are described for unreported alphaproteobacterial species in Korea. Gram reaction, colony and cell morphology, biochemical properties, and isolation sources are also provided in the species description section.

  • While screening indigenous prokaryotic species in Republic of Korea in 2017, a total of 17 bacterial strains assigned to the phylum Bacteroidetes were isolated from a variety of environmental habitats including water of fountain, tidal flat, plant root, soil, the gut of Russian grayling butterfly, ginseng field, seawater, lagoon and seashore sand. From the 16S rRNA gene sequence similarity of more than 98.7% and the formation of a robust phylogenetic clade with the closest species, it was found that the 17 strains belong to independent and recognized bacterial species. There has been no official report that the identified 17 species have been previously isolated in the Republic of Korea. Thus, 15 species in 10 genera of one family in the order Flavobacteriales, one species in one genus of one family in the order Cytophagales, and one species in one genus of one family in the order Sphingobacteriales are proposed as unrecorded species of the phylum Bacteroidetes found in the Republic of Korea. Gram reaction, colony and cell morphology, basic phenotypic characteristics, isolation source, taxonomic status, strain ID and other information are described in the species descriptions.

  • As a subset investigation to discover indigenous prokaryotic species in Korea, a total of 21 bacterial strains assigned to the class Betaproteobacteria were isolated from a wide range of environmental samples which collected from fresh water, roots of plants, mineral water and soil from ginseng farm. Phylogenetic analysis based on 16S rRNA gene sequences indicated that 21 isolated strains were most closely related to the class Betaproteobacteria, with high 16S rRNA gene sequence similarity (>99.1%) and constructed a robust phylogenetic clade with the closest species in the class Betaproteobacteria. These isolated species have no previous report or publication in Korea; therefore 17 species in 14 genera of 6 families in the order Burkholderiales, 1 species in the order Methylophilales, 2 species in 2 genera of 1 family in the order Neisseriales are reported for betaproteobacterial species found in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are also described in the species description section and as an image.

  • Reproductive dysfunction is a major health concern amongst the inhabitants of Tana River County. An ethno botanical study was conducted in Garsen, Itsowe and Ngao sub divisions of Tana River County to document the utilization of medicinal plants for the management of female reproductive ailments. The target population was practicing herbalists from Pokomo, Ormo and Giryama communities in the study area. Structured questionnaires and focussed group discussions were used to collect data. Forty eight plant species distributed in 40 genera and 29 families were documented as being important for the management of pregnancy related complications, menstrual disorders, infertility, fibroids and as contraceptives. The species most frequently cited by the herbalists were fourteen. Fifty two percent of the plant species were probably being mentioned for the first time as being useful in reproductive health management. In conclusion, Tana River has a pool of TMPs with a wealth of indigenous knowledge that needs to be exploited. The plants used to treat dysmenorrhea for example may be important analgesic agents that need further investigation while those with anti-fertility properties may contain steroidal phyto chemical compounds. Such species therefore need further investigation to establish their efficacy and mechanism of action.
