A new apotirucallane-type triterpenoid, $3{alpha}$-tigloylsapelin D (1) together with five known triterpenoids such as meliasenin B (2), sendanolactone (3), (-)-$12{eta}$-hydroxykulactone (4), cinamodiol (5), and $3{alpha}$-hydroxytirucalla-7,24(25)-dien-6-oxo-21,16-olide (6) were isolated from the fruits of Melia azedarach. Their structures were established on the basis of various NMR spectroscopic analyses including 2D-NMR techniques (HSQC, HMBC, and NOESY) and HR-FAB-MS data.
