Abstract

Graphical abstract: Highlights: The n -hexane extract of Hypericum laricifolium Juss. was phytochemically examined. The occurrence of three new acylphloroglucinol derivatives is reported. Their structures were established by analysis of their 1D-, 2D-NMR and mass spectra. Abstract: A new dimeric acylphloroglucinol derivative, hyperlaricifolin (1 ), and two new monomeric acylphloroglucinols, laricifolin A (2 ) and laricifolin B (3 ), were isolated from an extract of the aerial parts of Hypericum laricifolium Juss., along with the four known dimeric acylphloroglucinols uliginosin B, isouliginosin B, hyperbrasilol B, and isohyperbrasilol B. Their structures were elucidated by interpretation of their 1D-, 2D-NMR and mass spectra.
