A NEW cis-CAFFEOYL COUMARIN GLYCOSIDE FROM THE STEM BARKS OF Fraxinus depauperata

摘要

A new cis-caffeoyl coumarin glycoside, cichorigenin-5-O-(4'-cis-caffeoyl)-(beta-D-glucopyranoside (1), was isolated from the stein barks of Fraxinus depauperata, together with two known coumarins, cichorigenin (2) and esculin (3). The chemical structures of compounds 1-3 were elucidated through spectroscopic and chemical analysis, as well as by comparison with the literature. Compounds 2 and 3 are reported from this species for the first time.
