The isolation and structure elucidation of six new prenylated acylphloroglucinols, faberiones A-F, from the whole plant of Hypericum faberi is reported. Faberiones A-D (1-4) share a rare styrene substituent and may be biosynthetically generated via further acylation of the acylphloroglucinols. By analyzing the MS and NMR data, the structures of the new isolates were established. Faberiones B (2) and C (3) showed moderate cytotoxicity against the pancreatic cell line (PANC-1) with IC50 values of 6.2 and 9.0 μM, respectively.
