Abstract:
OBJECTIVETo study the chemical constituents of the marine sponge Rhabdastrella aff. distincta.
METHODCompounds were obtained by normal phase silica gel, Sephadex LH-20, reverse phase chromatogrophy and methylation method. These structures were determined on the basis of IR, MS, NMR spectral analysis.
RESULTEight compounds were isolated from bioactive CH3Cl fraction and identified as geoditin A (1), geoditin B (2), stellettin A (5), stellettin B (4), stellettin C (3), stellettinE (7), rhabdastrellic acid A (8) and the methyl ester of stellettin E (6).
CONCLUSIONAll these compounds were obtained from this species for the first time.
