Thirty two species of coastal plants (mainly halophytes) were investigated for their free amino acids and the total and water-soluble nitrogen contents in leaves. All plants except some species (e.g. Scutellaria and Linaria) contained proline, but only Ageratum. Tetragonia and Raphanus in rather high amounts, that it can be thought to serve as a cytoplasmic osmolyte. In some plant species (Euphorbia. Glehnia. Peucedanum. Raphanus and monocotyledonous Carex and Zoysia), however, hydroxyproline. (OH-Pro) rather than proline were accumulated to a considerable extent. The concentrations of total free amino acids were low in Aster tripolium, Linaria. Lysimachia. Plantago. Rumex, Vitex and especially in the members of the Chenopodiaceae and Crassulaceae. Marked differences also occurred in the nitrogen levels. Aizoaceae, Chenopodiaceae, Convolvulaceae, Cruciferae, Euphorbiaceae and Leguminosae usually showed high values of total and soluble amino nitrogen, while the opposite was true for most of the Cyperaceae, Gramineae, Lamiaceae, Plantaginaceae, Scophuriaceae, and Verbenaceae. The free amino acids in the investigated plant species contributed very little to the nitrogen content, but in plants of Euphorbia, Messerschmidia and Orostachys. their amino acid-N made up for 25∼30% of the total nitrogen. In conclusion, only a few cases did proline known as compatible solute constitute a significant proportion of the free amino acid pool in coastal plants.
