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.
