A new dimeric acylphloroglucinol, denudatin A (1), was isolated from the flowering aerials parts of Hypericum denudatum, along with the known phloroglucinols selancin A (2), hyperbrasilol A (3), uliginosin B (4), and isouliginosin B (5). The structure of 1 was elucidated using 1D, 2D NMR, and MS experiments, and by comparison with previously reported data for Hypericum dimeric acylphloroglucinols. Denudatin A (1) and selancin A (2) were administered orally to mice displaying antinociceptive activity in the hot plate test. The compounds did not induce motor impairment in the rotarod apparatus.
