[Abstract]
Investigation of the root of Pedicularis decora Franch. afforded two nor-monoterpene glucosides: pedicularis-lactone-1-O-β-glucoside(Ⅰ) and n?ngpogoside B (Ⅱ), which were isolated from Pedicularis L. for the first time. Their structures and relative configurations were elucidated by IR, MS, NMR, spectroscopic methods, including 2D-NMR and NOESY. Compound Ⅰ was new.
