A new lupane-type triterpene, named 7α,11β-dihydroxy-2,3-seco-lup-12(13),20(29)-diene-2,3,28-trioic acid (1), along with 5 other known lupane-type triterpenoids, namely 3β-hydroxy-lup-20(29)-ene-23,28-dioic acid (2), betulinic acid (3), betulinic acid 3-O-sulfate (4), 12(13)-ene betulinic acid (5), and betulinic acid glucoside (6), was isolated from Schefflera octophylla stems and leaves. The structures of these compounds were determined by 1D and 2D NMR, MS techniques, and chemical methods. Compound 1 was the new compound, and 2, 3, 5, 6 were isolated from S. octophylla for the first time.
