Eleven compounds were isolated from the aerial blooming parts of Hypericum trichocaulon Boiss. & Heldr., a narrow endemic plant of the island of Crete (Greece). These compounds comprise one previously undescribed prenylated phloroglycinol derivative (adhyperfoliatin), together with ten known compounds, procyanidin A(2), hyperixanthone A, (E)-chlorogenic acid, trans-phytol, five flavonoids, i.e. I3,II8-biapigenin, quercitrin, hyperoside, rutin, myricitrin and one fatty acid. The structures of the isolated compounds were established by means of 1D and 2D NMR, as well as MS spectral analyses. Phloroglucinol derivatives are recognized as chemophenetic markers for the genus Hypericum, and the isolation of adhyperfoliatin contributes to the characterization of the section Drosocarpium Spach, where the under-investigation taxon belongs. Moreover, the investigation of the methanol extract led to the isolation of myricitrin in high amounts, a specialized metabolite which also serves as a marker for this section.
