[Abstract]
Objective To investigate the chemical constituents from the roots of Ilex pubescensMethods The compounds were separated and purified by chromatography on silica gel, and Sephadex LH-20 columns. Their chemical structures were elucidated on the basis of spectroscopic methods and chemical evidencesResults A triterpenoid glycoside was purified and its structure was identified as 3-O-β-D-xylopyranosylspathodic acid (1)Conclusion Compound 1 is a new triterpenoid glycoside, named ilexsaponin D.
