Flavonoids from Stachys annua Growing in Azerbaijan

摘要

The new acylated flavonoid bioside 4′-O-methylisoscutellarein-7-O-[4′′′-O-acetyl]allopyranosyl-(1→2)-glucopyranoside ( 1 ) was isolated from the aerial parts of Stachys annua L. (Lamiaceae). Subterranean organs yielded for the first time 4′-O-methylisoscutellarein ( 2 ) and 4′-O-methylisoscutellarein-7-O-[6′′-Oacetyl] allopyranosyl-(1→2)-glucopyranoside ( 3 ). Chemical structures of the isolated compounds were elucidated using NMR spectroscopy.
