A new tirucallane, 3β-hydroxy-3-decarbonyl-24-epi-piscidinol A (1), and two new pairs of tetranortriterpene 23-epimers, named thaimoluccepimers A (2) and B (3), were isolated from the seeds of a Thai mangrove, Xylocarpus moluccensis. The structures of these compounds were elucidated by HRESIMS and NMR spectroscopic analysis.
从泰国红树林植物木果楝（Xylocarpus moluccensis）的种子中分离得到了一种新的四环三萜，3β-羟基-3-去羰基-24-表-鲷毒素A（1），以及两对新的四降三萜23-差向异构体，分别命名为泰国莫卢差向异构体A（2）和B（3）。通过高分辨电喷雾电离质谱（HRESIMS）和核磁共振波谱（NMR）分析确定了这些化合物的结构。
