New acylated flavone and cyanogenic glycosides from Linum grandiflorum
Magdy M. D. Mohammed,Lars Porskjær Christensen,Nabaweya A. Ibrahim,Nagwa E. Awad,Ibrahim F. Zeid,Erik B. Pedersen +5 more
TL;DR: The first investigation of Linum grandiflorum resulted in the isolation of one new acylated flavone O-diglycoside known as luteolin 7-O-α-D-(6′″-E-feruloyl)glucopyranosyl and two new cyanogenic glycosides, structurally elucidated via the extensive 1D, 2D NMR and DIFNOE.
