Two new limonoids,1α-tigloyloxy-3α-acetoxyl-7α-hydroxyl-12α-ethoxyl nimbolinin(1)and 1α-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.
