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)-beta-D-galactopyranoside (1) and fraxetin-8-O-(6'-O-galloyl)-beta-D-galactopyranoside (2) by spectral methods and chemical evidences.
