A new triterpene, named milemaronol (1), was isolated from Homalolepis suffruticosa Engl., Simaroubaceae, along with 10 known metabolites, chaparrinone (2), scopoletin (3), 5-methoxycanthin-6-one (4), eurylene (5), hispidol A (6), hispidol B (7), nilocitine (8), α-dihydronylocytine (9), β-dihydronylocytine (10), and teurilene (11). These compounds were characterized based on their spectral data, mainly 1D (¹H, ¹³C-APT) and 2D (¹H-¹H-COSY, NOESY, HSQC, HMBC) NMR and their mass spectra (HR-ESI-MS), in comparison with data from the literature. Compounds 1 to 6, 8, and 9 were evaluated for their antimycobacterial activity against 2 strains (H37Rv and M299).

从Simaroubaceae的Homalolepis suffruticosa Engl。中分离出一种新的三萜烯，命名为milemaronol（1），以及10种已知的代谢物，查帕瑞酮（2），大戟素（3），5-甲氧基天花素-6-一（4），二烯（5）），组氨酸A（6），组氨酸B（7），尼罗西汀（8），α-二氢顺式鸟碱（9），β-​​二氢顺式鸟碱（10）和丁草烯（11）。这些化合物根据其光谱数据进行表征，主要是1D（¹ H，¹³ C-APT）和2D（¹H- ¹ H-COSY，NOESY，HSQC，HMBC）NMR和它们的质谱（HR-ESI-MS），与来自文献的数据进行比较。化合物1到6，8，和9中它们对2个菌株（H37Rv株和M299）抗分支杆菌活性进行评价。
