In the present paper, have been investigated the free amino acids in the methanol extract of Desmarestia ligulata of which cells show extremely high acidity. The results obtained are as follows: 1) The precipitated fraction with barium hydroxide of the methanol extract of Desmarestia ligulata was subjected to a confirmatory analysis for the barium and sulfate ions. The low pH value of the methanol extract of this marine alga was found to be mostly attributed to the presence of easily separable sulfuric acid. 2) Free amino acids in the adsorbable fraction of the algal extract on the column of Dowex 50 X-4 were found to be asparagine, aspartic acid, glutamic acid, proline, alanine, valine and leucine. At the same time chondrine, 1-4-thiazane-3-carboxylic acid-1-oxide, isolated previously from Chondria crassicaulis is also confirmed to occur in Desmarestia ligulata. 3) Taurine and unknown B were detected in the adsorbable fraction of the algal extract on the column of Dowex 2.
