Phytochemical and chemotaxonomic study on Iris albicans Lange leaves

Phytochemical investigation of the leaves of Iris albicans afforded eleven known compounds, including seven isoflavonoids (1–7) and four xanthones (8–11). The structures of these compounds were elucidated on the basis of spectral analysis and literature data. All compounds were reported for the first time from I. albicans. The chemotaxonomic significance of the isolated compounds was summarized.
