Eight new eremophilanolides (1, 2, 4-7, 9, and 10), a new eremophilane (13), and several known compounds were isolated from the roots and aerial parts of Senecio mairetianus. The chemical structures were proposed taking into consideration spectroscopic analyses and chemical transformations. X-ray diffraction analysis of 2, 4, and 9 confirmed their structures. The stereochemistry of 1,10-epoxy-8alp
从千里光(Senecio mairetianus)的根和地上部分中分离出八种新的eremophilanolides(1、2、4-7、9和10),一种新的eremophilane(13)和几种已知的化合物。考虑到光谱分析和化学转化,提出了化学结构。2、4和9的X射线衍射分析证实了它们的结构。测定了1,10-环氧-8α-甲氧基过氧化氢物(3)的立体化学。化合物4-7、9和10是通过制备生物碱提取物而获得的可能的假象。
