As a part of our ongoing research program to isolate novel phragmalin limonoids from the stem bark of Chukrasia tabularis var. velutina, two new phragmalin limonoids orthesters, tabularin Q (1) and tabulalide O (4), along with two known compounds tabularin C (2) and tabularin H (3) were isolated. Their structures were elucidated by means of extensive 1D and 2D spectroscopic analyses which included HSQC, HMBC, and ROESY experiments and HR-ESI-MS.
作为我们从毛红椿茎皮中分离新型苦木素柠檬苦素类化合物的持续研究项目的一部分，我们分离出了两种新的苦木素柠檬苦素类化合物orthesters，tabularin Q（1）和tabulalide O（4），以及两种已知化合物tabularin C（2）和tabularin H（3）。通过广泛的一维和二维光谱分析（包括HSQC、HMBC和ROESY实验以及HR-ESI-MS）阐明了它们的结构。
