dc.description.abstract | Extracts of 13 species of marine ascidian collected in Algoa Bay were analyzed by LC-ICP-MS/ESI-MS. This technique allows
parallel analysis of the molecular species and the presence of certain elements. The LC-ICP-MS/ESI-MS technique was used to
target iodinated metabolites in this study. Three ascidian species afforded the known 3,5–diiodo-4-methoxyphenethylamine
(12), which was confirmedby the isolation of this metabolite fromAplidium monile.MS also suggested the presence of theknown
3,5–dibromo-4-methoxyphenethylamine (10) and the new 3-bromo-5–iodo-4-methoxyphenethylamine (11) in the A. monile
extract. The presence of the known 3,5-dibromotetramethyltyrosine (21) and the new 3-iodotetramethyltyrosine (23) in extracts
of an unidentified Didemnum species was similarly proposed from MS evidence. This is the first report of the occurrence of
iodinated metabolites in South African marine invertebrates. | en_US |
