The five known phenylethanoid glycosides, cistanoside F, beta-hydroxyacteoside, campenoside I, acteoside and orobanchoside, and a new phenylethanoid glycoside, beta-oxoacteoside, were isolated from the aerial parts of Plantago depressa. The structure of beta-oxoacteoside was deduced from chemical and spectral evidence to be beta-oxo-beta-(3,4-dihyroxyphenyl)-ethyl-O-alpha-L-rhamnopyranosyl-(1 --> 3)-beta-D-(4-O-caffeoyl)-glucopyranoside.
