Among these brown algae, Turbinaria ornata and T. conoides 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 T. conoides samples from several Indian and Pacific Ocean islands. This nonvariable discriminant molecule was only identified in T. conoides specimens, but not in the two allied species T. ornata and T. decurrens. Results are discussed with regard to turbinaric acid as an interesting chemomarker isolated from T. conoides and the rapid discrimination of Turbinaria specimens using chemical assays. specialized Chemotaxonomy HRMAS NMR Pacific islands Turbinaria conoides Turbinaria ornata Turbinaric Acid PACIFIQUE 034 020 50 6 1048-1057 2014 0022-3646 https://www.documentation.ird.fr/hor/fdi:010063121 10.1111/jpy.12235 0022-3646 [F B010063121] https://www.documentation.ird.fr/hor/fdi:010063121 https://www.documentation.ird.fr/intranet/publi/2015/01/010063121.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-02-02 2017-08-23 fdi:010063121 fre
