A New Flavonoid Glycoside from Schizonepeta annua

A new flavonoid glycoside 1 was isolated from Schizonepeta annua (Pall.) Schischk. by column chromatography. Its structure was determined to be acacetin 7-O-α-L-rhamnopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→6)]-β-D-glucopyranoside (1) by spectroscopic data ( 1 H NMR, 13 C NMR, 1 H− 1 H COSY, HSQC, and...

Zusammenfassung:A new flavonoid glycoside 1 was isolated from Schizonepeta annua (Pall.) Schischk. by column chromatography. Its structure was determined to be acacetin 7-O-α-L-rhamnopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→6)]-β-D-glucopyranoside (1) by spectroscopic data ( 1 H NMR, 13 C NMR, 1 H− 1 H COSY, HSQC, and HMBC) and chemical methods. In addition, the α-glucosidase inhibitory activity of compound 1 was evaluated.
