It 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. Cytotoxic effects of H. The present work suggested that Holothuria atra extracts showed virucidal action through reduction in number of plaques formed during plaque reduction assay against the HSV-1 and HSV The methanol extracts of Holothuria atra showed maximum inhibition of antitumor cells and it was observed by cell inhibition using tryphan blue.

Similarly the inhibitory effects of Herpes simplex virus 1 and 2 cells were detected using the plaque reduction assay. The tested viruses were affected with the increase in concentration of extracts. Halodeima atra is a black sea cucumber with black tentaclesfrequently covered with sand H. The mean live weight is about g and can reach up to 1 kg. Column chromatography Silica mesh gel slurry was prepared using methanol.

Percentage of growth inhibition was identified at different concentration of the extracts. Holothuria atra Jaeger, [2]. Antitumor activity was measured by using the IC 50 values.

Bioactive peptides and hemolytic lectins have been reported from sea cucumber as a source of antiviral activity. A new cytotoxic holothjria triterpene glycoside from the sea cucumber Holothuria impatiens. Shallow-water populations are denser and composed of smaller individuals, holorhuria reproduce mostly by transversal fission, while populations in deeper waters with larger and more atrw individuals reproduce sexually. This page was last edited on 13 Aprilat Triterpene glycosides are the predominant secondary metabolites of the sea cucumber Hemoiedema spectabilis which exhibited wide spectra of biological activities, including antifungal, cytotoxic, hemolytic, cytostatic and immunomodulatory functions Chludil et al.
