A new phenylethanoid glucoside, 2-(3,4-dihydroxyphenyl)-ethyl-O-beta-D-gluc
opyranosyl-(1 --> 6)-3-O-trans-caffeoyl-beta-D-glucopyranoside, named isolu
grandoside, was isolated from Fraxinus ornus bark, together with the five k
nown phenylethanoid glycosides 2-(4-hydroxyphenyl)-ethyl-(6-O-caffeoyl)-bet
a-D-glucopyranoside, calceolarioside B, verbascoside, isoacteoside and lugr
andoside. Isomerization of lugrandoside to isolugrandoside was not found un
der the employed conditions of isolation and purification. (C) 1998 Elsevie
