title: Apotirucallane and tirucallane triterpenoids from Cedrela sinensis.
abstract: Nine new triterpenoids, 1-9, were isolated from the cortex of Cedrela sinensis (Meliaceae), together with six known compounds, sapelin E acetate, grandifoliolenone, azadirone, bourjotinolone A, piscidinol A, and hispidol B. The structures of 1-9 were determined by the 2D NMR experiments, chemical methods, and X-ray crystallography.
