Two new neolignans from Syringa velutina Kom.

Two new neolignans, (7S,8R)-guaiacylglycerol-8-O-4'-sinapyl ether 9'-O-beta-D- glucopyranoside (1) and (7S,8R)-syringylglycerol-8-O-4'-sinapyl ether 9'-O-beta-D-gluco- pyranoside (2) were isolated from the leaves of Syringa velutina Kom.. Their structures were established by chemical properties and spectroscopic evidence.
