From the benzene and ethyl acetate soluble fractions of an ethanolic extract of roots of Prosopis juliflora two new flavanone glycosides have been isolated and characterised as 3′, 4′-dihydroxy 5-methoxy 6-methyl flavanone 7-0-β-D-glucopyranoside (I) and 7,4′-dimethoxy 6,8-dimethyl flavanone 5-0-β-D-galactopyranoside (II).
