Twenty-three new triterpenoids (1-23), all having an apotirucallane skeleton, were isolated from the seeds, leaves, and stems of Cedrela sinensis (Meliaceae). Their structures were determined by 2D NMR experiments, X-ray crystallographic analysis, and chemical methods. These triterpenoids showed a moderate cytotoxic activity against P-388 murine leukemia cells (IC50 0.26-9.9 mu g/mL). (c) 2005 Elsevier Ltd. All rights reserved.
