Six new triterpenesaponins, ilexasprellanosides A-F (1-6, resp.), together with eleven known compounds were isolated from the roots of Ilex asprella. The new saponins were characterized as ursa-12,18-dien-28-oic acid 3-O-β-D-xylopyranoside (1), 19α-hydroxyursolic acid 3-O-β-D-(2'-O-acetylxylopyranoside) (2), 19α-hydroxyursolic acid 3-O-β-D-glucuronopyranoside (3), 3β,19α-dihydroxyolean-12-en-23,28-dioic
