Abstract
Some photophysical, photochemical and photobiological properties of nine anthraquinones (AQs) isolated from a phototoxic plant, Heterophyllaea
pustulata, were studied. The photosensitized generation of superoxide anion radical (O2•−) and singlet molecular oxygen (1O2) by three
of the nine AQs, namely heterophylline, pustuline and 5,5-bisoranjidiol was evaluated. Whereas the O
