Abstract: Two new phenylpropanoid glycosides, pediculariosides Eand I, were isolated from whole plants of Pedicularis lasiophrys Maxim and P.longifora Rudolph, respectively.On the basks of spectral data and chemical evidence, their structures were determined to be 1'-O-β-.D-(3-methoxy-4-hydroxyl-β-phenyl)-etliyl-6' -O-feruloyl-a-L-(2-acetyl)-rhamnosyl (1→3')-4'-O-acetyl-glucopyranoside and 1' -O-β-D-(3-methoxy-4-hydroxy-β-phenyl)-ethyl-a-L-rhamnosyl (1→3')-a-L-arabino.syl(1→4')-6' -O-feruloyl-glucopyranoside.
