Qualitative and quantitative determinations were made on free amino acids contained in 75 kinds of domestic lichens, using an automatic amino acid analyzer (Hitachi Model KLA-2) and the total nitrogen was determined by the semimicro-Kjeldahl method. Correlation among the genus and species of lichens with the kind and content of amino acids and total nitrogen was examined. Some difference was observed even among the same genus and there seemed to be hardly any correlation. The kind of amino acids contained in individuals was 19 at the most, while only five kinds were present in some. As far as the 75 kinds of lichens examined in the present series of work were concerned, total nitrogen was less than 1% in 53 kinds, 1-2% in 12 kinds, 2 -3% and 3-4% in four each, and more than 4% in one. The total nitrosen content of Peltigera variolosa (Mass.) Gyeln. was the highest among all the lichens examined with 4.52%, but its free amino acid content rather low. This is probably due to the present of nitrogenous compounds other than amino acids. Of these 75 kinds of lichens, four kinds of Lobaria genus and three kinds of Sticta genus, both of Stictaceae family, had larger content of total nitrogen than other genus. It was of interest that taurine was found in 11 kinds of lichens including Alectoria sulcata Gyeln., Cetraria pseudocomplicata Asahina and Cladonia aggregata (Sw.) Ach. All of the 75 kinds of lichens examined were found to have a few Ninhydrin-positive substances which could not be identified. [in Japanese]
