Secoiridoid components from Jasminum grandiflorum

Secoiridoid glucosides, 2″-epifraxamoside and demethyl-2″-epifraxamoside, and the secoiridoid, jasminanhydride were isolated from Jasminum grandiflorum together with four previously known phenolics and a triterpene. Structures were elucidated by detailed spectroscopic analysis. Stereochemistry of the compounds was determined by differential NOE experiment.
