Structure Elucidation of Two Secoiridoid Glucosides from Jasminum officinale L. var. grandiflorum (L.) KOBUSKI

Phytochemical investigation of the dried leaves of Jasminum officinale var. grandiflorum has led to the isolation of two new secoiridoid glucosides, (2"R)-2"-methoxyoleuropein and (2"S)-2"-methoxyoleuropein, together with four known secoiridoid glucosides, oleuropein, ligstroside, demethyloleuropein and oleoside dimethyl ester, a lignan, (-)-olivil and p-hydroxyphenethyl alcohol. The structures of the new compounds were elucidated from chemical and spectroscopic evidence.
