从采自越南中部地区的Harrisonia perforata叶中分离得到两个新的重排柠檬苦素类化合物，命名为haperorine A（1）和haperorine E（2），经X-射线衍射分析确定其结构。通过化学相关性确定次要化合物的结构为12-去乙酰基贯叶连翘碱A（3）。报道了它们的核磁共振和质谱性质。
Two new rearranged limonoids, named haperforine A (1) and haperforine E (2), were isolated from a sample of Harrisonia perforata leaves collected in Center Vietnam and their structures determined by X-ray diffraction analysis. The structure of a minor compound was established as 12-desacetylhaperforine A (3) by chemical correlation. Their NMR and mass spectroscopic properties are reported.
