Abstract

A new phenylethanoid glucoside, 2-(3,4-dihydroxyphenyl)-ethyl-O-.beta.-D-glucopyranosyl-(1,6)-3-O-trans-caffeoyl-.beta.-D-glucopyranoside, named isolugrandoside (I), was isolated from Fraxinus ornus bark, together with the five known phenylethanoid glycosides 2-(4-hydroxyphenyl)-ethyl-(6-O-caffeoyl)-.beta.-D-glucopyranoside, calceolarioside B, verbascoside, isoacteoside and lugrandoside. Isomerization of lugrandoside to isolugrandoside was not found under the employed conditions of isolation and purification.
