Antibacterial Activity of Dihydroquercetin Separated from Fructus Polygoni orientalis against Clavibacter michiganensis subsp. sepedonicus via Damaging Cell Membrane.

ABSTRACT: The yield and quality of potato can be severely affected by bacterial ring rot, which is caused by Clavibacter michiganensis subsp. sepedonicus (Cms). Recently, using natural compounds to control bacteria has received more attention. In this study, five antibacterial compounds from ethyl acetate (EtOAc) extract of Fructus Polygoni orientalis (FPO) against Cms were isolated and the most active compound was screened. Five active compounds were identified as 3,3'-di-O-methylellagic acid (1), 3,3'-di-O-methylellagic acid-4-O-β-D-glucopyranoside (2), dihydroquercetin (3), protocatechuic acid (4) and quercetin (5). Compound 3 (dihydroquercetin, DHQ) was confirmed as the most active compound. The dia
