Abstract
A study ofAlsidium helminthocorton Kütz. (Rhodophyceae) an alga with anti-helminthic activity, led to the separation of free imino-acids identified by IR and1H-NMR spectroscopy as alpha-kainic acid, alpha-kainic acid lactone and alpha-allokainic acid. In addition, a novel peptide was isolated, of 37 amino-acids including two kainic acid residues in its sequence.
