Caffeic acid esters of phenylethanoid glycosides from Fraxinus ornus bark
Phytochemistry 50(2) (1999)
297-301
A new phenylethanoid glucoside, 2-(3,4-dihydroxyphenyl)-ethyl-O-β-D-glucopyranosyl-(1→6)-3-O-trans-caffeoyl-β-D-glucopyranoside, named isolugrandoside, was isolated from Fraxinus ornus bark, together with the five known phenylethanoid glycosides 2-(4-hydroxyphenyl)-ethyl-(6-O-caffeoyl)-β-D-glucopyranoside, calceolarioside B, verbascoside, isoacteoside and lugrandoside. Isomerization of lugrandoside to isolugrandoside was not found under the employed conditions of isolation and purification.
