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.
在三齿胡椒的果实中鉴定出一种新型的三萜环阿屯型化合物，命名为 hirtinone（1），六种原柠檬素类化合物 - nilocitin（2）、二氢 nilocitin B（3）、melianone 差向异构体（4）和（5）、piscidinol A（6）和 melianone 内酯（7），一种三萜类化合物 hirtin（8）和一种倍半萜类化合物 spathulenol（9）。结构通过 1D 和 2D NMR（1H 和 13C-NMR、DEPTQ、1H-1H-COSY、1H-1H-NOESY、HSQC 和 HMBC）、高分辨率质谱（HR-ESI-MS）和红外（IR）光谱数据确定。
