A new prenylated benzophenone, hypatulin C (1), was isolated from the leaves ofHypericum patulumtogether with a biogenetically related analog, hypelodin B (2). Hypatulin C (1) had a tricyclic [4.3.1.03,7]-decane moiety substituted by four prenyl groups. The structure of1was elucidated by detailed spectroscopic analyses, while the absolute stereochemistries of1and2were assigned by comparison of their ECD spectra with TDDFT calculated spectra.
