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 compds. were isolated from the aerial parts of Hypericum humifusum ssp. austral. The structures of 1-6 were elucidated by mass spectrometry and extensive 1D and 2D NMR spectroscopy.
