A new nonglycosidic secoiridoid, ligstral and two new secoiridoid digl
ucosides, angustifolioside A[6''-O-(beta-D-glucopyranosyl)-oleuropein]
and angustifolioside B [6''-O-(beta-D-glucopyranosyl)-ligstroside], w
ere isolated from the methanolic extract of the leaves of Fraxinus ang
ustifolia along with the two known secoiridoid glucosides, ligstroside
and oleuropein. The chemical structures of the isolated compounds wer
e established by chemical and spectral evidence.
