Flavonol glycoside gallate and ferulate esters from Persicaria lapathifolia as inhibitors of superoxide production in human monocytes stimulated by unopsonized zymosan.

Abstract:

:Aerial parts of Persicaria lapathifolia S.F. Gray (Polygonaceae) exhibited an inhibitory effect on superoxide production in unopsonized zymosan-stimulated human monocytes. Two known compounds, quercetin 3-O-beta-(2"-galloyl)-glucopyranoside and quercetin 3-O-beta-(2"-galloyl)-rhamnopyranoside, and a new compound, quercetin 3-O-beta-(6"-feruloyl)-galactopyranoside, were isolated as the inhibitors of superoxide production by activity-guided fractionation. IC50 values were shown at the concentrations of 2.1 microM by quercetin 3-O-beta-(2"-galloyl)-glucopyranoside, 1.9 microM by quercetin 3-O-beta-(2"-galloyl)-rhamnoypranoside, and 3.5 microM by quercetin 3-O-beta-(6"-feruloyl)-galactopyranoside whose inhibitory potencies were similar to oxyphenylbutazone (IC50 = 1.9 microM) as a positive control.
