Three new phenylethanoid glycosides, named scrosides A-C and a new iridoid glycoside, named picroside IV, have been isolated from the underground parts of Picrorhiza scrophulariiflora, together with 11 known compounds. Their structures were elucidated by the means of 2D NMR spectroscopy and chemical methods.
