Abstract

A gallotannin (1) and two ellagitannins (2 and 3) containing a salidroside (p-hydroxyphenethyl alcohol 1-O-β-D-glucoside) core have been isolated from the bark of Quercus stenophylla MAKINO (Fagaceae). On the basis of chemical and spectroscopic evidence, their structures have been elucidated unequivocally as 2", 3", 4", 6"-tetra-O-galloyl salidroside (1), 2", 3"-di-O-galloyl-4", 6"-(S)-hexahydroxydiphenoyl salidroside (2) and 3"-O-galloyl-4", 6"-(S)-hexahydroxydiphenoyl salidroside (3).
