he crude organic extracts of ascidian species collected from Algoa Bay, South Africa were analysed using liquid chromatography with parallel inductively coupled plasma mass spectrometry/electrospray mass spectrometry (LC-ICP-MS/ESI-MS). The data obtained was used to detect a number of brominated and iodinated tyramine and tyrosine derivatives with in the ascidian extracts establishing this method as a powerful tool for the dereplication of halogenated metabolites in complex mixtures.
