Detailed phytochemical investigation of the roots of Erythrophleum fordii furnished seven undescribed cassane-type diterpenoids, erythrocassanoids A-E and erythro-norcassanoids A, B and two known clerodane diterpenes, 15-hydroxy-3-cleroden-2-one and methyl ester of 2-oxopopulifolic acid. Their structures were determined by 1D, 2D NMR and HRESIMS analysis. The antiviral activities of these compounds were evaluated. Among them, 15-hydroxy-3-cleroden-2-one and methyl ester of 2-oxopopulifolic acid showed antiviral activities against influenza virus and coxsackie virus with IC values ranging from 11.11 to 29.60 μM.
对黔桂鹅掌柴根的详细植物化学研究提供了七个未描述的卡烷型二萜，即 erythrocassanoids A-E 和 erythro-norcassanoids A、B，以及两个已知的 clerodane 二萜，15-羟基-3- cleroden-2-one 和 2-氧代 populifolic 酸甲酯。它们的结构通过 1D、2D NMR 和 HRESIMS 分析确定。评估了这些化合物的抗病毒活性。其中，15-羟基-3- cleroden-2-one 和 2-氧代 populifolic 酸甲酯对流感病毒和柯萨奇病毒具有抗病毒活性，IC 值范围为 11.11 至 29.60 μM。
