%X One novel triterpene cycloartane-type, named hirtinone ( 1), six protolimonoids ¨C nilocitin ( 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 ( 1H and 13C-NMR, DEPTQ, 1H- 1H-COSY, 1H- 1H-NOESY, HSQC and HMBC), high resolution mass spectroscopy (HR-ESI-MS) and infrared (IR) spectral data.
