Summary 1. An electro-chromatographic method was developed for the separation and identification of 26 different amino acids. This method proved to be time saving and most suitable for routine analyses in physicochemical work. 2. This technique was applied in studying the amino acid pattern of algal extracts of nine common species representing Chlorophyta, Phaeophyta and Rhodophyta, from Alexandria shore. 3. A semi-quantitative method, based on visual comparison of intensity of colour and size of spots with standardized records, was described and used in this investigation. 4. The comparative results showed that the highest amino acid content was found in Pterocladia, followed by Ulva and Dictyota for the protein fraction; Codium, Pterocladia and Enteromorpha for the peptide fraction, and Pterocladia, Hypnea and Codium for free amino acids. 5. Each alga has its own amino acid pattern in the proteins, peptides and free state; but qualitative differences were less significant than quantitative variations, which may not conform to the general pattern of the group.
