This study deals with the isolation of a new acylated  5,6,7,3',4'-pentahydroxy-flavone glycoside (1) and 3 known  allose-containing acylated flavone glycosides (2-4) as well as a known  flavone aglycone (5) from the aerial parts of Veronica pectinata var.   glandulosa and V. persica.  The structures of the isolated compounds  were determined to be 3' -hydroxy-4'-O-methylscutellarein-7-O-[2''-O-a  -L-rhamnopyranosyl-3''-O-(6''''-O-acetyl-b -D-glucopyranosyl)]-b-  D-glucopyranoside, named sarachoside (1), 4' -O-methylisoscutellarein-7-O-2''-  O-(6''' -O-acetyl-b -D-allopyranosyl)-b -D-glucopyranoside (2),  isos\-cutellarein-7-O-2''-O-(6'''-O-acetyl-b-D-allopyranosyl)-b-  D-glucopyranoside (3), 3'-hydroxy-4'-O-methy\-lisoscutellarein-7-O-2''  -O-(6'''-O-acetyl-b -D-allopyranosyl)-b -D-glucopyranoside (4)  and 5,4'-dihydroxy-6,7,3' -trimethoxyflavone, named circilineol (5) by  extensive 1-D and 2D-NMR spectroscopy.  Sarachoside (1) exhibited  potent radical scavenging activity against  2,2-diphenyl-1-picrylhydrazyl (DPPH) radical.
