The total of amino acid pools of three plant species common in Brullus Lake and belonging to different taxonomic groups were determined using LKB Alpha Plus high performance amino acid analyzer.The results indicated that presence of seventeen of common amino acids in these three different species, however, their concentrations varied.Glutamic acid represented the major constituent of amino acid pools separated from Inula erithmoides and Potamogeton pectinatus.Proline represented the major constituent of amino acid pool in Halimione portulacoides.The highest total content of amino acids was measured in , followed by Potamogeton pectinatus and Inula erithmoides.From the two sulphur containing amino acid: methionine and cysteine, only methionine was detected in all studied species.
