Two new phenylethanoid glycosides and a new secoiridoid glycoside from the roots of Picrorhiza scrophulariiflora

Two new phenylethanoid glycosides, named scroside H (1), scroside I (2), and a new secoiridoid glycoside, named picrogentioside I (3), have been isolated from the underground parts of Picrorhiza scrophulariiflora. Their structures were elucidated on the basis of spectroscopic evidence.
