Phenylpropanoid glycosides isolated from Scrophularia scopolii

A new phenylpropanoid glycoside, angoroside A, and a known glycoside, acteoside, were isolated from the roots of Scrophularia scopolii var. scopolii. On the basis of chemical and spectral evidence, angoroside A was shown to be 3,4-dihydroxy-β-phenylethoxy-O-α-l-arabinopyranosyl-(1 → 6)-α-l-rhamnopyranosyl-(1 → 3)-4-O-caffeoyl-β-d-glucopyranoside.
