Flavonoid Glycosides from Fruit Shells of Phoenix dactylifera L.

Abstract

Two new natural flavonoids, chrysoeriol-7-O-β-L-arabinofuranosyl (1→2)-β-D-apiofuranoside and isorhamnetin 3-O-β-(4"- p-hydroxybenzoyl) galactopyranoside have been isolated from the acetone extract of the fruit shells of Phoenix dactylifera along with seven known flavonoids. The structure of the isolated compounds was elucidated on the basis of chemical analyses and spectral evidence. The antioxidant activity of the extract was also evaluated.
