Abstract: Objective: To screen inhibitory activity of pigments extracted from two sea-anemones, Heteractis magnifica (H. magnifica) and Stichodactyla haddoni (S. haddoni) against 10 aquatic and 10 human bacterial pathogens. Methods: Crude pigment were extracted by using acetone solvent and the pigment extracts were fractionated into 7 for H. magnifica and 5 for S. haddoni by using silica gel column chromatography and also tested for the antibacterial activity using Agar welldiffusion method. Results: The 3rd fraction of H. magnifica and 2nd fraction of S. haddoni displayed higher activity against eight aquatic bacterial pathogens and seven human bacterial pathogens. Conclusions: The 3rd fraction of H. magnifica showed higher antibacterial activity than the crude pigment extracts and other fractions of H. magnifica and S. haddoni. Thus the sea-anemone Heteractis magnifica is promising for further exploration of antibacterial drugs. [Copyright &y& Elsevier] |
