A new sesquiterpene cacaroborin (1) was isolated from the roots of Cacalia roborowskii, together with three known ones, cinalbicol (2), isopetasin (3), and 3alpha-angeloyloxylactone (4). The structure of compound 1 was elucidated as 1beta,10alpha-dihydroxy-8alpha-methoxyeremophil-7(11)-en-8beta,12-olide on the basis of spectral evidence (1D, 2D NMR, IR, EI-MS, and HR-ESI-MS) and X-ray diffraction analysis.
从祁连风毛菊的根部分离得到一种新的倍半萜类化合物卡罗布林（1），以及三种已知化合物，即西那比考尔（2）、异蜂斗菜素（3）和3α-当归酰氧基内酯（4）。基于光谱证据（一维、二维核磁共振、红外光谱、电子轰击质谱和高分辨电喷雾电离质谱）和X射线衍射分析，化合物1的结构被鉴定为1β,10α-二羟基-8α-甲氧基埃里莫芬-7(11)-烯-8β,12-内酯。
