Six new benzophenone glycosides, 2,3′,4,5′,6-pentahydroxybenzophenone 4-O-(6″-benzoyl)-β-d-glucopyranoside (1), 2,3′,4,5′,6-pentahydroxybenzophenone 4-O-β-d-glucopyranoside (2), 2,3′,4,5′,6-pentahydroxybenzophenone 2-O-(2″-benzoyl)-α-l-arabinopyranoside (3), 2,3′,4,5′,6-pentahydroxybenzophenone 2-O-α-l-arabinopyranoside (4), 2,3′,4,5′,6-pentahydroxybenzophenone 2-O-(4″-acetyl)-β-d-xylopyranoside (5), and 2,3′,4,5′,6-pentahydroxybenzophenone 3-C-(4″-benzoyl)-β-d-glucopyranoside (6), and five known compounds were isolated from the aerial parts of Hypericum humifusumssp. austral. The structures of 1–6were elucidated by mass spectrometry and extensive 1D and 2D NMR spectroscopy.
