🎯
Amaç & Hipotez: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.
📊
Temel Bulgular & Veri: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.

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.
