Abstract: In this review, an updated literature survey covering the reports of naturally occurring xanthones in the period of 2005-2008 is presented. In some 143 studies, the isolation of 264 different xanthones from 36 plant species (representing 15 genera in 6 families of higher plants), 7 species of fungi, and 1 lichen species were reported. Of these, 122 compounds were isolated for the first time from nature. We discuss plant origin, the way of separation, and spectral analysis done for structure elucidation, along with a brief discussion of the chemosystematic significance.
