Abstract
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.
