New cytotoxic aristolactams from Pararistolochia flos-avis.
Two new aristolactams, aristolactam-FI [1] and -FII [2], were isolated from active extracts of Pararistolochia flos-avis. Their structures were elucidated on the basis of nmr, ms, uv, and ir spectral data. Aristolactam-I [3] and -AII [4] were also isolated from this plant. Aristolactam-AII showed cytotoxicity against PS and KB cells in culture.
