Abstract

Two new C-15 enolic acyl phragmalin-type limonoid orthoesters, chukvelutilide G (1) and chukrasine F (2), were isolated from the stem barks of Chukrasia tabularis var. velutina. Their structures were elucidated by their extensive high resolution-electrospray ionization mass spectrometry (HR-ESI-MS), one- and two-dimensional spectroscopic analysis, including heteronuclear single quantum coherence (HSQC), HMBC and NOESY experiments.

摘要

从皱叶黄梁木（变种）的茎皮中分离得到了两种新的 C-15 烯醇酰基胡椒烷型柠檬苦素正交酯，chukvelutilide G（1）和 chukrasine F（2）。通过其广泛的高分辨率电喷雾电离质谱（HR-ESI-MS）、一维和二维光谱分析，包括异核单量子相干（HSQC）、HMBC 和 NOESY 实验，阐明了它们的结构。
