Four new limonoids, 11α-hydroxygedunin (1), 11β-hydroxygedunin (2), 7-deacetoxy-7α,11α-dihydroxygedunin (3), and 7-deacetoxy-7α,11β-dihydroxygedunin (4), were isolated from the cortex of Cedrela sinensis, together with three known compounds, gedunin (5), 7-deacetoxy-7α-hydroxygedunin (6), and 11-oxogedunin (7). The structures of 1-4 were determined by a combination of 2D NMR experiments and chemical methods and by X-ray crystallography of 1 and 2.
