摘要

A novel glycoside compound, 3-hydroxy-5-(β-D-glucopyranosyloxy)-hexanoic acid (1) has been isolated from the fruits of Aronia melanocarpa (Michx.) Britton, along with ten known compounds, vanillic acid 4-O-β-D-glucoside (2), (R)-4-O-β-D-glucopyranoyl-4-hydroxy-2-pentanone (3), (6R,9R)-roseoside (4), phloroacetophenone 2-O-glucoside (5), methyl (3S,5S)-5-hydroxy-3-(β-D-glucopyranosyloxy)hexanoate (6), β-D-glucopyranosyl benzoate (7), parasorboside (8), benzyl 6-O-α-L-arabinofuranosyl-β-D-glucoside (9), dihydrophasmaric acid 4′-O-β-D-glucopyranoside (10), and 4-O-β-D-glucopyranosyl-cis-p-coumaric acid (11). The structure of compound 1 was determined by NMR spectroscopic and MS analyses. Compounds 1–4 showed antibacterial activity against Staphylococcus aureus RN (4220).
