Kainic acid in the seaweed Palmaria palmata (dulse)
ABSTRACT Twenty samples of the seaweed Palmaria palmata (dulse) purchased mainly from commercial Internet shops on the European market were analysed by a liquid chromatograph coupled with a tandem mass spectrometer method for the content of kainic acid, a naturally occurring neurotoxic compound in P. palmata. Kainic acid levels in the samples ranged widely from trace levels to approximately 560 μg g−1 dry weight.
Distribution of neuroexcitatory amino acids in marine algae
Abstract Contents of three neuroexcitatory amino acids, N- methyl- d,l -aspartic acid (NMA), kainic acid (KA) and domoic acid (DA) were investigated in 46 marine algae species. NMA was detected in very small amounts in several marine algae belonging to the Chlorophyceae and Rhodophyceae, but not in algae belonging to the Phaeophyceae. KA was detected in three species and DA was detected in four species all belonging to the family Rhodomelaceae (Ceramiales, Rhodophyceae). Among rhodomelacean algae investigated in this study, KA and DA were detected only in the particular species collected in the south-west Islands of Japan (Tokunoshima Island and Okinawa Main Island). It is noteworthy that the distribution of both KA and DA was strictly restricted some algae of the subtropical area.
