Coumarin glycosides from Euphorbia soongarica (Boiss)

Abstract

Two new coumarin glycosides (1 and 2), along with six known compounds (3–8), were isolated from the roots of Euphorbia soongarica. The structures of two new compounds were elucidated as aesculetin-6-O-(6′-O-galloyl)-β-d-galactopyranoside (1) and fraxetin-8-O-(6′-O-galloyl)-β-d -galactopyranoside (2) by spectral methods and chemical evidences.
