目的 研究鬼箭羽（卫矛Euonymus alatus带栓翅的枝条）中的化学成分。方法 采用多种柱色谱技术对鬼箭羽95%乙醇提取物进行分离纯化，根据理化性质和波谱数据进行结构鉴定。结果 从鬼箭羽提取物中分离得到了3个化合物，分别鉴定为（1S，2S，7E，11R，12S）-2，11-dihydroxy-1，12-oxidocembra-4（18），7（8）-diene（1）、hemerocallal A（2）、桦木酸甲酯（3）。结论 化合物1为新的西松烷型二萜，命名为鬼箭羽二萜A，化合物2和3为首次从鬼箭羽中分离得到。

Objective To study the chemical constituents from the twigs of Euonymus alatus. Methods Compounds were isolated and purified by a combination of various chromatographic techniques, and their structures were elucidated by physiochemical property and spectral analysis. Results Three compounds were obtained from 95% ethanol extract of the twigs of E. alatus and identified as (1S,2S,7E,11R,12S)-2,11-dihydroxy-1,12-oxidocembra-4(18),7(8)-diene (1), hemerocallal A (2), and betulinic acid methyl ester (3). Conclusion Compound 1 is a new cembranoid diterpene and named euonymuditerpene A, and compounds 2 and 3 are isolated from the twigs of Euonymus alatus for the first time.
