PHENYLETHANOID GLYCOSIDES FROM PLANTAGO DEPRESSA

Article abstract of DOI:10.1016/0031-9422(93)85238-M

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