Iridoid and phenylpropanoid glycosides from Pedicularis artselaeri

Six new compounds, an iridoid glucoside, 6-O-methylepiaucubin (1), three ir idoids, artselaenins A (3), B (4), C (13), a phenylethanoid glycoside, arts elaeroside A (14), and a phenylpropanoid glycoside, artselaeroside B (15), as well as fourteen known compounds, nine Iridoid glycosides (2, 5-12) and five phenylpropanoid glycosides (16-20) were isolated from the whole plants (including roots, stems, leaves and flowers) of Pedicularis artselaeri. Th eir structures were identified mainly by spectral evidence.
