Studies on the Constituents of Syringa Species. VIII. Isolation and Structures of Phenylpropanoid Glycosides from the Leaves of Syringa reticulata (BLUME) HARA

Two new phenylpropanoid glycosides, named oleoacteoside and oleoechinacoside, have been isolated from the fresh leaves of Syringa reticulata (BLUME) HARA. These compounds were also detected in the methanolic extract of the leaves of Syringa vulgaris LINN. Their structures were elucidated on the basis of nuclear magnetic resonance, circular dichroism spectra and some other physicochemical evidence.
