A New Secoiridoid Glycoside from Roots of Picrorhiza scrophulariiflora

Abstract Objective To study the chemical constituents in the roots of Picrorhiza scrophulariiflora . Methods The chemical constituents in the roots of P. scrophulariiflora were separated and purified with chromatographic methods. The structures were elucidated by spectroscopic methods and chemical analyses. Results A new secoiridoid glycoside, picrogentioside II (1) was successfully isolated from the roots of P. scrophulariiflora . Conclusion Compound 1 is a new secoiridoid glycoside.
