Abstract

Four new geranyl-bearing polyisoprenylated benzoylphloroglucinol derivatives, hypersampsone I (1), hypersampsone J (2), and hypersampsone K (3), together with hypersampsone L (4) which possessed a novel skeleton, were isolated from the fruit of Hypericum sampsonii. Their structures were determined on the basis of spectroscopic data, mainly 1D- and 2D-NMR spectroscopy and mass spectrometry. The structures of 1 and 2 were confirmed by X-ray crystallographic analysis.
