Two novel acylated diarylheptanoid glycosides, oregonosides A and B (3
, 4, respectively), were isolated from red alder bark and their struct
ures established by spectrometric techniques. The compounds were ident
ified as O-(6-O-benzoyl-beta-D-glucopyranosyl)-heptan-3-one and 6-O-va
nilloyl-beta-D-glucopyranosyl)-heptan-3-one.
