Phytochemical analysis on the leaves of Agathis microstachya J.F. Bailey & C.T. White.

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.
