摘要：

Six new prenylated phloroglucinol derivatives, hypersampsones A-F (1-6), were isolated from the aerial part of Hypericum sampsonii, together with 2,4,6-trihydroxybenzophenone, 2,4,6-trihydroxybenzophenone 4-O-geranyl ether, 2,4,6-trihydroxybenzophenone 3-C-geranyl ether, sampsoniones D and H. Their structures were elucidated by spectroscopic methods, mainly 1D- and 2D-NMR spectroscopy and mass spectrometry.
