A rare sesquiterpenoid possessing a 6/6 bicyclic system fused with two clustered furan units and a pair of guaiane-type sesquiterpenoids were acquired from the roots of Chloranthus henryi. Their structures with absolute configurations were characterized with spectroscopic data, ECD, and X-ray diffraction analysis. All three sesquiterpenoids showed moderate neuroprotective activities on PC12 cells damaged with hydrogen peroxide.
从金粟兰科植物金粟兰 Chloranthus henryi 的根部分离得到了三个罕见的倍半萜类化合物，它们均具有 6/6 双环系统，与两个聚集的呋喃单元融合，并带有一对瓜环型倍半萜类化合物。通过光谱数据、ECD 和 X 射线衍射分析确定了它们的结构和绝对构型。这三个倍半萜类化合物均对过氧化氢损伤的 PC12 细胞显示出中等的神经保护活性。
