Abstract
A new phenolic glycoside syringate, 4'-hydroxy-2',6'-dimethoxyphenol 1-O-beta-D: -(6-O-syringoyl) glucopyranoside (1), together with two known ones, 2'-hydroxy-4'-methoxyphenol 1-O-beta-D: -(6-O-syringoyl) glucopyranoside (2) and 4'-hydroxy-2'-methoxyphenol 1-O-beta-D: -(6-O-syringoyl) glucopyranoside (3), were isolated from the bark of Juglans mandshurica MAXIM. var. sieboldiana MAKINO. Their structures were established on the basis of spectral and chemical data.
