Marine Species Identification Portal : Holothuria atra
Silica mesh gel slurry was prepared using methanol. V Isolation and structure of cerebrosides atda the sea cucumber Pentacta australis Liebigs. Similarly the inhibitory effects of Herpes simplex virus 1 and 2 cells were detected using the plaque reduction assay. Holohuria favours reef flats where it is not fully exposed to the waves but the water is well aerated, and shallows beside slabs of rock from under which cool water wells out when the tide retreats.
A total of 59 natural compounds were identified from the extracts of sea cucumber H.
The body is elongated and cylindrical with rounded ends and a smooth skin. This article is published under license to BioMed Central Ltd. Eur J Org Chem. Considering these as well as the results of present investigations, the methanolic extracts of Holothuria atra stra form effective antitumour and antiviral agents.
Considering this as an evidence in the present study, attempts were made to find out the bioactive compounds from marine invertebrates such as the Holothuria. They are major constituents of c, c alkyl chain and double bonds Sugwara et al. Then it was centrifuged at rpm for 15 min. In India, about species of holothurians are known of which 75 species are from shallow waters within 20 m depths Cuvillier The structure of bioactive compounds was elucidated by using NMR spectra from the active fractions.
The extract LPS obtained from Stichopus japonicus induced inflammatory response via blocks the MAPK signaling pathway in murine macrophages, showed in vitro with anti-inflammatory potential Himayaa et al. Small specimens tend to have a thin coating of sand with open patches of black skin showing through, large specimens are seen either with no sand covering or with a thick unbroken covering above. Abstract The sea cucumber Holothuria atra extracts have been evaluated for the presence of bioactive compounds and various biological activities.
Anti bacterial activity of the column purified fractions of sea cucumber, Holothuria atra against A Serratia liquefaciens B Escherichia coli C Klebsiella pneumoniae D Staphylococcus aureus.
Structure and Bioactivity of sulphated polysaccharides. These suggest the possibility of apoptotic cell death through the activation of Bax a proapoptotic protein. The present work suggested that Holothuria atra extracts showed virucidal action through reduction in number of plaques formed holohhuria plaque reduction assay against the HSV-1 and HSV The mouth is on the underside at one end and is surrounded by a fringe of 20, black, branched tentacles.
Column chromatography Silica mesh gel slurry was prepared using methanol.
IUCN Red List of Threatened Species
The concentration of extracts for H. Author information Article notes Copyright and License information Disclaimer. The species may be misidentified as Holothuria leucospilota, which is very similar.
Trypan blue dye exclusion test Being an essential dye, Tryphan blue was used in estimating the number of viable cells present in a population. Black Sea Cucumber Local name: Dilution of virus Concentration of H. NMR analysis The active fractions obtained from column chromatography were analysed for Nuclear magnetic resonance arra NMR analysis. Bioactive triterpene glycosides from the sea cucumber Holothuria fuscocinerea. These results will direct future efforts to optimize the anti proliferative activity of these bioactive compounds.
The extracts of H. In vivo and in vitro biosynthesis of saponins in sea cucumbers. Sea cucumber derived fucosylated chondroitin sulfates FCS which inhibited the growth of human immunodeficiency virus and also acted as a cytotoxic agent was initially obtained from Stichopus badionotus Kaswandi et al. It was placed in the subgenus Halodeima by Pearson inmaking its full scientific name Holothuria Halodeima atra.
The susceptibility of cells to the extract exposure was characterized by IC 50 values. The cell proliferation and inhibition measurment of the sea cucumber Holothuria atra showed that it can be developed as an antitumor agent. The plates were aseptically streaked with the test microorganism using a sterile swab and allowed to dry for a few minutes. The sea cucumber Holothuria atra extracts have been evaluated for the hilothuria of bioactive compounds and various biological activities.
No Name of the compound Molecular formula M. In such places it is often found in pools above holoyhuria low tide mark which are warmed by the sun during the day.
World Register of Marine Species. After washing the column with same solvents, the sample 3 to 5 ml was poured and then eluted with methanol: Sphingoid base composition of cerebrosides from sea cucumber Stichopus variegatus exhibited cytotoxicity against human colon cancer cell and induced apoptosis.
