Three quassinoids, eurycolactone D (1), eurycolactone E (2) and eurycolactone F (3) were isolated from the roots of Eurycoma longifolia Jack. The structures of 1-3 were elucidated by spectroscopic methods, and that of 3 was further confirmed by X-ray crystallography. The known quassinoids, laurycolactone B (4) and eurycomalactone (5) were also identified.
从长叶刺蒺藜根中分离出三种苦木素类化合物，即刺蒺藜内酯D（1）、刺蒺藜内酯E（2）和刺蒺藜内酯F（3）。通过光谱方法阐明了1-3的结构，3的结构通过X射线晶体学进一步得到证实。还鉴定出了已知的苦木素类化合物，月桂内酯B（4）和刺蒺藜内酯（5）。
