Abstract

<abstract abstract-type="main" id="jpy12235-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Several species of the genus <italic>Turbinaria</italic> coexist along the coasts of islands in the Indian and Pacific Oceans. Among these brown algae, <italic>Turbinaria ornata</italic> and <italic>T. conoides</italic> are sister species that are difficult to differentiate using exclusively morphological characters. Based on in vivo nuclear magnetic resonance and chromatographic techniques, i.e., liquid and gas chromatography‐mass spectrometry analysis, combined with phylogenetic data, we successfully identified turbinaric acid in <italic>T. conoides</italic> samples from several Indian and Pacific Ocean islands. This nonvariable discriminant molecule was only identified in <italic>T. conoides</italic> specimens, but not in the two allied species <italic>T. ornata</italic> and <italic>T. decurrens</italic>. Results are discussed with regard to turbinaric acid as an interesting chemomarker isolated from <italic>T. conoides</italic> and the rapid discrimination of <italic>Turbinaria</italic> specimens using chemical assays.</p> </abstract>
