ABSTRACT: During screening of seaweeds from different places in Europe for antimicrobial activities against human and fish pathogenic bacteria, Laurencia chondrioides was identified as a promising species. By bioassay-guided isolation, followed by structure elucidation by mass spectrometry and 1H- and 13C-NMR spectrometry, two sesquiterpenoides of the chamigrene-type from the selected red seaweed Laurencia chondrioides were identified. Both compounds inhibit the growth of some fish and human pathogenic bacteria.
