Abstract

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.
