The leaf extract of gave two new modified -abietane diterpenoids, zanzibariolides A () and B (), and two known triterpenoids, simiarenol () and β-amyrin (). The structures of the isolated compounds were elucidated based on NMR and MS data analysis. Single-crystal X-ray diffraction was used to establish the absolute configurations of compounds and . The crude leaf extract inhibited the infectivity of herpes simplex virus 2 (HSV-2, IC 11.5 μg/mL) and showed toxicity on African green monkey kidney (GMK AH1) cells at CC 52 μg/mL. The isolated compounds - showed no anti-HSV-2 activity and exhibited insignificant toxicity against GMK AH1 cells at ≥100 μM.
从 中得到的叶提取物含有两种新的改性 -abietane 二萜，即 zanzibariolides A()和 B()，以及两种已知的三萜，simiarenol()和 β-香树脂醇()。根据 NMR 和 MS 数据分析，确定了分离化合物的结构。单晶 X 射线衍射用于确定化合物和的绝对构型。粗提叶提取物抑制单纯疱疹病毒 2（HSV-2，IC 11.5 μg/mL）的感染力，在 CC 52 μg/mL 时对非洲绿猴肾（GMK AH1）细胞表现出毒性。分离的化合物-对 HSV-2 没有抗活性，在 ≥100 μM 时对 GMK AH1 细胞也没有明显的毒性。
