Objective To investigate the chemical constituents from the roots of Pedicularis henryi. Methods The compounds were isolated by the combined separation Sephadex LH-20, RP18, MCI-gel CHP-20P, and semipreparative HPLC column chromatography. The structures were identified on the basis of NMR data and the comparison with literatures. Results Nine compounds were isolated from the 95% ethanol extract of P. henryi, and identified as syringaresinol mono-β-D-glucoside (1 ), plantarenaloside (2 ), phenylacetic acid (3 ), 2", 3"-O-acetylmartynoside (4 ), cis-2", 3"-O-acetylmartynoside (5 ), martynoside (6 ), cis-martynoside (7 ), leucoseceptoside A (8 ), and jionoside D (9 ). Conclusion Compounds 1—9 are isolated from this species for the first time.
