Abstract

Two novel phenol glucoside gallates, querglanin and isoquerglanin, were isolated from the leaves of Quercus glauca. From chemical and spectroscopic evidence, they were characterized as 2-iso-propyl-4-hydroxyl-5-methyl phenol 1-O-β-d(6′-O-galloyl)glucopyranoside and 2-iso-propyl-4-hydroxyl-5-methyl phenol 1-O-β-d-(3′-O-galloyl)glucopyranoside, respectively. In addition, the occurrence of seven known flavonoids was demonstrated.
