The supernatant was collected and filtrated.

In the Pacific Islands, Holothuria atra is collected by diving or by wading at low tide, and used for human consumption; its commercial value, however, is low. The compounds were identified by comparison with the standards.

From Wikipedia, the free encyclopedia. The antiviral activity was defined as the percentage of plaque inhibition as follows: Study on antivirus effect of fucoidan in vitro. It has a smooth, pliable, entirely black skin which often has sand ho,othuria to it, especially in smaller individuals.

Structure and Bioactivity of sulphated polysaccharides.

The spectra were obtained using the standard Bruker software. Implications for holothhuria and haemolytic processes. Devaraj Isaac Dhinakaran, Email: The present work suggested that Holothuria atra extracts showed virucidal action through reduction in number ayra plaques formed during plaque reduction assay against the HSV-1 and HSV Disc diffusion method was employed to test the active fractions of H.

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.

IUCN Red List of Threatened Species

Structure of neuritogenic active gangliosides from the sea cucumber Stichopus japonicas; pp. Biosci Biotechnol and Biochem. IC 50 values were calculated Percentage inhibition of novel compounds against all cell lines was calculated using the following formula: The methanol extracts showed anti proliferative activities against the Hela and MCF-7 cell lines. Cytotoxic effects of H. It was done to avoid formation of secondary plaques.

Holothuria atra

The interpretation on mass spectrum GC-MS was carried out and the spectra of the unknown component were compared to the spectrum of the known components stored in the NIST library. The skin portion was peeled off and stored in methanol in separate containers. It was placed in the subgenus Halodeima by Pearson inmaking its holithuria scientific name Holothuria Halodeima atra.

Abstract The sea cucumber Holothuria atra extracts have been evaluated for the presence of bioactive atrs and various biological activities. It is the type species of the subgenus. Sphingoid base composition of cerebrosides from sea cucumber Stichopus variegatus exhibited cytotoxicity against human colon cancer cell and induced apoptosis. These suggest the possibility of apoptotic cell death through the activation of Bax a proapoptotic protein.

Table 3 Percentage cell inhibition and holothurla of cell line exposed to Holothuria atra using tryphan blue. The methanol extract of the sea cucumber H. Class — sea cucumbers, Holothuroidea; order — Aspidochirotida; family — holothuriids, Holothuriidae.

Oligosaccharide mapping of low molecular weight heparins: The anus is at the other end. Articles with ‘species’ microformats. No Name of the compound Molecular formula M. The antiviral activity was defined as the percentage of plaque inhibition as follows:.

Bioactive compounds from Holothuria atra of Indian ocean

The 13C NMR spectrum showed the presence of a carbon—carb on double and indicated the presence of two conjugated carbonyls. The GC conditions were as follows: Sea Cucumbers of Northern Australia. The number of live and dead cells were recorded.

W 1 Ethane 11dichloro CAS 11dichloro ethane. The species is fished in some parts of its range, but the processed product is of low commercial value. The cell inhibition was determined from the extract concentration ranged from 0.

Benefits of a sea cucumber extract in anti-angiogenic therapy and RTK inhibition for cancer. The mean live weight is about g and can reach up to 1 kg. It is a small to very large species up to mmfissiparouscylindrical with rounded ends, a smooth tegument and a pliable body wall. Holothuria atra is often found associated with the polychaete worm Gastrolepidia clavigeraa black worm which crawls about over the sea cucumber’s skin.
