Illihenin A (), a novel sesquiterpenoid, was isolated from the roots of . The structure was determined by spectroscopic analyses, ECD calculation, and single-crystal X-ray diffraction. Compound represents a class of novel 5/7/6 tricyclic sesquiterpenoids featuring a rare cage-like tricyclo[6.2.2.0]dodecane core. A plausible biosynthetic pathway of by rearrangement of -cedrane is proposed. Additionally, showed potent antiviral activity against coxsackievirus B3 with an IC value of 2.87 μM.
异落叶松脂素 A（Illihenin A），一种新型的倍半萜，从 的根部中分离得到。结构通过光谱分析、ECD 计算和单晶 X 射线衍射确定。化合物 代表了一类新型的 5/7/6 三环倍半萜，具有罕见的笼状三环[6.2.2.0]十二烷核心。提出了通过 -cedrane 重排生成 的可能生物合成途径。此外， 对柯萨奇病毒 B3 表现出强烈的抗病毒活性，IC 值为 2.87 μM。
