In order to find new and biologically active compounds, the constituents of the root bark of Melia toosendan were investigated, and three new limonoids, 29‐[(2‐methylbutanoyl)oxy]‐2 α ‐hydroxyamoorastatone ( 1 ), 1,3‐ epi ‐29‐[(2‐methylbutanoyl)oxy]‐2 α ‐hydroxyamoorastatone ( 2 ), and 1,3‐ epi ‐29‐[(2‐methylpropanoyl)oxy]‐2 α ‐hydroxyamoorastatone ( 3 ), were isolated from the root bark of Melia toosendan. Their structures were elucidated by means of extensive spectroscopic studies.
