OBJECTIVE
To study the chemical constituents of the roots of Incarvillea mairei.
METHODS
The chemical constituents were isolated and purified by chromatographic techniques with silica gel, Sephadex LH-20 column, and preparative TLC. Structures of the compounds were identified by spectroscopic methods.
RESULTS
Seven compounds were obtained and elucidated as 1-O-methyl-guaiacylglycerol (1), 1-O-feruloyl-3-O-(26"-hydroxylhexacosoyl) glycerol (2), incarvine D (3), piceid (4), 6'-8"E, 11"E-octadecadienoyl-clionasterol-3-glucoside (5), beta-sitosterol (6), and beta-daucosterol (7).
CONCLUSIONS
Compounds 1-7 were isolated from I. mairei, and among them 1 and 2 were new compounds, 4, 5 were isolated from the genus Incarvillea for the first time.
