Abstract
Three new triterpenoids, 19-hydroxy-2,3-secours-12-ene-2,3,28-trioic acid 3- methyl ester (1), 19-hydroxy-1-oxo-2-nor-2,3-secours-12-ene-3,28-dioic acid (2), and (3beta,18alpha,19alpha)-3,28-dihydroxy-20,28-epoxyursan-24-oic acid (3), were isolated from the roots of Potentilla multicaulis. Their structures were elucidated on the basis of spectroscopic methods (IR, HR-ESI-MS, and 1D- and 2D-NMR). Compound 2b exhibited moderate cytotoxic activity against human promyelocytic leukemia (HL-60) cells.
