Two new neo-clerodane type furano diterpenoids were isolated from the aerial part of Croton schiedeanus, besides the clerodane diterpenes cis- and trans-dehydrocrotonin, previously isolated from other species of Croton. Structural elucidation was achieved on basis of extensive NMR experiments, including X-ray diffraction analysis and molecular mechanics calculations. The previously known flavonoids ayanin and quercetin-3,7-dimethyl ether were also obtained from the extract of this plant.
除了之前从巴豆属其他物种中分离得到的克罗烷二萜顺式和反式脱氢巴豆素外，还从施氏巴豆的地上部分分离出两种新的克罗烷型呋喃二萜。通过广泛的核磁共振实验，包括X射线衍射分析和分子力学计算，完成了结构解析。还从该植物提取物中获得了之前已知的黄酮类化合物阿亚宁和槲皮素-3,7-二甲醚。
