Hypericum sampsonii Hance (Clusiaceae) is a folk medicine used in Taiwan to treat blood stasis, relieve swelling, and as an anti-hepatitis drug. Two new polyprenylated phloroglucinol derivatives, hypersampsone R (1) and hypersampsone S (2), and a known prenylated benzophenone, hyperibone K (3) were isolated from the aerial parts of H. sampsonii. Their structures were determined by extensive 1D and 2D NMR, and MS spectral analyses. View Full-Text
