Two new phenolic glycosides-3'-O-beta-D: -glucopyranosysalidroside (1) and cis-echinacoside (2)-together with four known ones-forsythoside B (3), decaffeoylacteoside (4), osmanthuside F (5) and (-)-olivil-4'-O-beta-D: -glucopyranoside (6)-were isolated from the leaves of Syringa reticulata. Their structures were established on the basis of spectral and chemical data.

D010636	Phenols	Benzene derivatives that include one or more hydroxyl groups attached to the ring structure.
D010936	Plant Extracts	Concentrated pharmaceutical preparations of plants obtained by removing active constituents with a suitable solvent, which is evaporated away, and adjusting the residue to a prescribed standard.	Herbal Medicines,Plant Extract,Extract, Plant,Extracts, Plant,Medicines, Herbal
D006027	Glycosides	Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed.
