Spirocyclic Acylphloroglucinol Derivatives from Hypericum pyramidatum

Abstract

Five spirocyclic acylphloroglucinol derivatives (1–5) have been isolated from a hexanes extract of the leaves of Hypericum pyramidatum. Pyramidatones A-D (1–3, 5) are new, and chipericumin C (4) has been previously reported. The acylphloroglucinols were characterized based on spectroscopic (NMR, IR, UV-VIS) and mass spectrometric data.
