目的 研究冬青科冬青属植物救必应Ilex rotunda 的化学成分。方法 对救必应95%乙醇提取物的石油醚部位和醋酸乙酯部位进行色谱分离，根据光谱数据和理化性质确定各化合物的结构。结果 分离得到1个新化合物二丁香醚（1）和6个已知成分，分别为木栓酮（2）、3-羟基齐墩果烷（3）、紫丁香苷（4）、芥子醛葡萄糖苷（5）、十九烷酸（6）、硬脂酸（7）。结论 化合物1为新化合物，化合物2为首次从冬青属植物中分离得到。

Objective To investigate the chemical constituents in the bark of Ilex rotunda Methods The constituents of the acetidin and petroleum ether-soluble portions in 95% ethanol extract were isolated and purified by means of chromatography. Structures were identified by their physicochemical characteristics and spectral features. Results Seven compounds were isolated and identified as disyringin ether (1), friedelin (2), 3β-OH-oleanane (3), syringin (4), sinapaldehye glucoside (5), nonadecylic acid (6), and stearic acid (7). Conclusion Compound 1 is a new compound. Compound 2 is isolated from the plants of Ilex L. for the first time.
