Three new compounds from the leaves of Acanthopanax senticosus Harms

Three new compounds named (2E)-prenyl benzoate-4-O-α-l-arabinopyranosyl (1 → 6) β-d-glucopyranoside (1), 7-methoxy-8-O-β-d-glucopyranosyl coumarin (2), and 3,4′-dihydroxy-3′-methoxy benzenepentanoic acid (3) were isolated from the leaves of Acanthopanax senticosus Harms. The structures of new compounds were determined by means of 2D NMR experiments and chemical methods.
