Abstract

Hypericum is a prolific source of acylphloroglucinol derivatives. Unlike the monomeric polyisoprenylated acylphloroglucinols hyperforin and adhyperforin, which are the main phloroglucinols in Hypericum perforatum (section Hypericum), dimeric structures are to the best of our knowledge exclusively reported in sections Brathys and Trigynobrathys belonging to the genus Hypericum. Their occurrence, as well as the analytical properties of the thirty-one dimeric acylphloroglucinols currently reported for Hypericum spp. are reviewed. Additionally, the presence of dimeric acylphloroglucinol in four Peruvian Hypericum species is presented and their chemotaxonomic significance explored.
