Two new neolignan glycosides from leaves of Osmanthus heterophyllus.
Two new neolignan glycosides, (7R, 8R)-threo-guaiacylglycerol-8-O-4'-sinapyl ether 7-O-beta-D: -glucopyranoside (1) and (7S, 8R)-5-methoxydehydrodiconiferyl alcohol 4-O-beta-D: -glucopyranoside (2), and four known ones (3-6), were isolated from the leaves of Osmanthus heterophyllus. The structures of compounds 1-6 were established on the basis of spectral and chemical data.
