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.
