Abstract

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 humifusum ssp. austral. The structures of 1-6 were elucidated by mass spectrometry and extensive 1D and 2D NMR spectroscopy.
