Two acylated diarylheptanoid glycosides from red alder bark
Two novel acylated diarylheptanoid glycosides, oregonosides A and B (3, 4, respectively), were isolated from red alder bark and their structures established by spectrometric techniques. The compounds were identified as (5S)-1,7-bis(3, 4-dihydroxyphenyl)-5-O-(6-O-benzoyl-beta-D-glucopyranosyl)-heptan-3-o ne and (5S)-1,7-bis(3, 4-dihydroxyphenyl)-5-O-(6-O-vanilloyl-beta-D-glucopyranosyl)-heptan-3 -one.
