Abstract
Two new ellagic acid glycosides, named stachyanthuside A (1) and B (6), have been isolated along with four known ellagic compounds (2–5) from the leaves of Diplopanax stachyanthus. The structures of the new compounds were established as 3′-O-methylellagic acid 4-O-β-d-glucopyranoside (1) and 3,3′,4′-tri-O-methylellagic acid 4-O-β-d-(2″-acetyl)-glucopyranoside (6) on the basis of detailed spectroscopic analysis and comparison with related model compounds.
