One novel triterpene cycloartane-type, named hirtinone (1), six protolimonoidsnilocitin (2), dihydronilocitin B (3), melianone epimers (4) and (5) , piscidinol A (6) and melianone lactone (7) , one tertranortriterpenoid, hirtin (8), and one sesquiterpene, spathulenol (9), were identified in the fruits of Trichilia hirta. The structures were established by 1D and 2D NMR ( 1 H and 13 C-NMR, DEPTQ, 1 H-1 H-COSY, 1 H-1 H-NOESY, HSQC and HMBC), high resolution mass spectroscopy (HR-ESI-MS) and
