Abstract:
Objective: To study the constituents in the roots of Picrorhiza scrophulariiflora. Methods: The constituents of P. scrophulariiflora were separated and purified with chromatographic methods. The structures were elucidated by spectroscopic methods and chemical analyses. Results: Four compounds isolated from the 90% ethanol extract in the roots of P. scrophulariiflora were identified as picrogentioside D (1), sweroside (2), gentiopicroside (3), and mannitol (4). Conclusion: Compounds 1-4 are obtained from the roots of P. scrophulariiflora for the first time and compound 1 is a new secoiridoid glycoside, named picrogentioside D.
