New triterpenoid glycosides from the roots of Ilex asprella

Eight new triterpenoid glycosides, named ilexasosides A–H, were isolated from the roots of Ilex asprella. Their structures were elucidated by spectroscopic and chemical analyses. Ilexasosides B and D are rare sulfated derivatives of ursane-type triterpenoid glycosides.
