Abstract: One novel triterpene cycloartane-type, named hirtinone (1), six protolimonoids – 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.
Keywords: Meliaceae; Trichilia hirta; terpenoids; NMR data
