Two new ellagic acid glycosides from leaves of Diplopanax stachyanthus.
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-beta--glucopyranoside (1) and 3,3',4'-tri-O-methylellagic acid 4-O-beta--(2'-acetyl)-glucopyranoside (6) on the basis of detailed spectroscopic analysis and comparison with related model compounds.
