Two new limonoids,1α-tigloyloxy-3α-acetoxyl-7α-hydroxyl-12α-ethoxyl nimbolinin（1） and lα-benzoyloxy-3α-acetoxyl-7α- hydroxyl-12α-ethoxyl nimbolinin（2）,were isolated from the fruits of Melia toosendan.Their structures were established on the basis of various NMR spectroscopic analyses,including 2D-NMR techniques（HSQC,HMBC,NOESY） and HR-ESI-MS.
