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.
Keywords:
Palmaria palmata; dulse; kainic acid; seaweed.
