从酸枣根中分离得到1个新黄酮类化合物，命名为（R）-2-hydroxynaringenin（1），另外还分离得到15个已知化合物，包括6个黄酮类化合物（2-7）、6个木脂素类化合物（8-13）、2个酚苷类化合物（14-15）和1个生物碱类化合物（16）。变种 spinosa (Bunge) HuexH. F.小周。通过1D和2D NMR、圆二色谱（CD）曲线分析和文献数据的比较，确定了它们的结构。化合物2、3和8-16在Z. jujuba Mill.变种化合物8、10和13-15为鼠李科新化合物。此外，本文还讨论了这些分离物的化学分类学意义。(C)2013爱思唯尔有限公司保留所有权利。
One new flavonoid, named (R)-2-hydroxynaringenin (1), along with fifteen known compounds, including six flavonoids (2-7), six lignans (8-13), two phenolic glycosides (14-15) and one alkaloid (16) were isolated from the roots of Zizyphus jujuba Mill. var. spinosa (Bunge) Hu ex H. F. Chou. Their structures were established on the basis of spectroscopic evidence, including 1D and 2D NMR, circular dichroism (CD) curve analysis, and by comparison with literature data. Compounds 2, 3 and 8-16 were found in Z. jujuba Mill. var. spinosa for the first time, while compounds 8, 10 and 13-15 were new to the Rhamnaceae family. In addition, the chemotaxonomic significance of the isolates was discussed in this paper. (C) 2013 Elsevier Ltd. All rights reserved.
