Three novel rearranged tigliane-type diterpenoids, euphebrananes A-C (), and one precursor tigliane-type diterpenoid, euphebrananes D (), were isolated from the roots of . The structures of isolates were identified by comprehensive spectroscopy, HRESIMS, quantum chemical calculations (ECD and NMR), and X-ray crystallography. Euphebrananes A-C represented a tigliane-type diterpenoid, and a plausible biosynthetic pathway of – was proposed. In vitro, anti-inflammatory and estrogen-like activity screening showed that exhibited weak related biological activities.

从大戟中发现重排的提利亚烷型二萜类化合物

从 .通过综合光谱学、HRESIMS、量子化学计算（ECD 和 NMR）和 X 射线晶体学鉴定了分离物的结构。 Euphebrananes AC 代表一种 tigliane 型二萜类化合物，并提出了一个合理的生物合成途径。体外抗炎和类雌激素活性筛选显示，其相关生物活性较弱。
