Ten new compounds (
1–
10), pruniflorone A–J, together with 21 known compounds (
11–
31) were isolated from the roots and barks of
Cratoxylum formosum ssp.
pruniflorum. Their structures were determined by spectroscopic methods. Compounds
1 and
11 were also confirmed by X-ray diffraction data. In addition, antibacterial and cytotoxic activities of the isolates were also evaluated.
Nine new prenylated xanthones (
1–
9) and a new anthraquinone (
10) were isolated from the roots and barks of
Cratoxylum formosum ssp.
pruniflorum. In addition, antibacterial and cytotoxic activities of the isolates were also evaluated.
