One new ionone glycoside, pedicurexoside (1), one new flavonoid, 5, 4'-dihydroxy-3'-methoxyflavone-7-O-6 ''-n-butyryl-beta-D-glucopyranoside (2), two new iridoid glycosides, 6-O-ethyl-aucubin (7), 6-O-ethyl-epiaucubin (8), and one new phenylpropanoid glycoside, 4-hydroxy-phenylpropenyl-alpha-L-rhamnopyranosyl-(1 -> 3)-4-O- feruloyl-beta-D-glueopyranoside (13), together with eleven known compounds, apigenin (3), lutcolin (4), chrysoeriol (5), luteolin-7-O-beta-D-glucopyranoside (6), aucubin (9), yuhemoside (10), euphroside (11), mussaenoside (12), verbascoside (14), martynoside (15) and isomartynoside (16), were isolated from Pedicularis rex. The structures of 1 - 16 were elucidated mainly by ID and 2D NMR techniques, NIS evidence and chemical methods. The ionone derivative with thirteen carbon atoms.was found in Pedicularis plants for the first time.
