A previously undescribed naphthalenone derivative, sohiracillinone (), and a novel 4,5--lanostane triterpenoid, 11-ethoxydaedaleanic acid A () were isolated with two new lanostane triterpenoids, ceanphytamic acids A () and B (), from the EtOH extract of along with 17 known compounds ⁻. The absolute configuration of sohiracillinone () was unambiguously identified by NMR and electronic circular dichroism (ECD) data. The structures of other new compounds were elucidated on the basis of NMR and mass spectroscopy (MS), and the cytotoxic activities of all the isolated components were evaluated.
从 中用乙醇提取物分离得到了一个以前未描述的萘醌衍生物，sohiracillinone ()，以及一个新型的 4,5--lanostane 三萜，11-ethoxydaedaleanic 酸 A ()，还有两个新的 lanostane 三萜，ceanphytamic 酸 A () 和 B ()，以及 17 种已知化合物 ⁻。通过 NMR 和电子圆二色性 (ECD) 数据，明确确定了 sohiracillinone ()的绝对构型。其他新化合物的结构是基于 NMR 和质谱 (MS) 确定的，并评估了所有分离成分的细胞毒性活性。
