A phytochemical study of the ethanolic extract of Chrysosplenium carnosum Hook. f. et Thoms. led to the isolation of two new oleanane-type triterpenoids, 6β-hydroxy-3-oxoolean-12-en-27-oic acid (1) and 3β, 21α-dihydroxyolean-12-en-27-oic acid (2), along with fourteen known compounds (3–16), all of which were isolated from this plant for the first time. The structures of these compounds were established on the basis of spectroscopic methods. Compounds 1–4 were evaluated for their in vitro anti-tumor activities on B16F10, SP2/0 and Hep-G2 cells lines. Compounds 1, 3 and 4 exhibited strong inhibitory activity against B16F10 and SP2/0 cells' growth, compared with moderate cytotoxic activity against Hep-G2 cells. However, compound 2 showed to be inactive against these tumor cells.
