Original Articles


Four triterpenoids were isolated from the roots ofIlex 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 establishedI andII as 20-epipomolic acid and 24-carboxypomolic acid, repectively.
