The first phytochemical analysis on the leaves of Agathis microstachya J.F. Bailey & C.T. White collected in Rome was reported in this work. The study evidenced the presence of four compounds i.e., 7,4'''-dimethoxy-agathisflavone (1), 7,7''-dimethoxy-cupressuflavone (2), dactylifric acid (3) and shikimic acid (4) which were identified by means of spectroscopic techniques. Compounds (1, 2, 4) were reported in the species for the first time as well as this is the second report on the presence of dactylifric acid (3) in the whole Araucariaceae family. The absence of diterpenoids from the studied accession is also important. All these chemotaxonomic aspects were discussed.
