Özet
Two new polyphenolic compounds, myricetin 3-O-(2"-O-galloyl)-beta -D-glucopyranoside and (-)-6-chloroepicatechin, were isolated from the aerial parts of Geranium pratense subsp. finitimum (Woronow) Knuth, along with three known polyphenolic compounds [quercetin 3-O-(2"-O-galloyl)-beta -D-glucopyranoside, quercetin 3-O-(2"-O-galloyl)-beta -D-galactopyranoside, methyl gallate] and tryptophan. Quercetin 3-O-beta -D-glucopyranoside, quercetin 3-O-beta -D-galactopyranoside, quercetin 3-O-(2"-O-galloyl)-beta -D-glucopyranoside and quercetin 3-O-(2"-O-galloyl)-beta -D-galactopyranoside were found to be effective against free radical induced impairment of endothelium-dependent relaxation in isolated rat aorta.
