Four triterpenoids were isolated from the roots of Ilex pubescens : two new triterpenoids named pubescenolic acid (I) and pubescenic acid (II), and two known triterpenoids ilexolic acid (III) and oleanolic acid (IV). Chemical and spectroscopic studies have established I and II as 20-epipomolic acid and 24-carboxypomolic acid, repectively.
