Limonoids from Cedrela sinensis.
Five limonoids were isolated from the leaves of Cedrela sinensis (Meliaceae) and their structures were determined to be 11beta-hydroxy-7alpha-obacunyl acetate, 11-oxo-7alpha-obacunyl acetate, 11-oxo-7alpha-obacunol, 11beta-hydroxycneorin G, and 11-oxocneorin G, by 2D NMR spectroscopic experiments, X-ray crystallographic analysis, and chemical methods.
