Six novel phloroglucinol dialdehyde diterpene derivatives (macrocarpals B--G), which have antibacterial activity, were isolated from leaves of Eucalyptus macrocarpa. These compounds have closely related structures, the molecular formula for B--F being C28H40O6, and that of G being C28H38O5. The structures of macrocarpals B, D, and G were analyzed by means of NMR analyses.
从大果桉树叶中分离出六种具有抗菌活性的新型间苯三酚二醛二萜衍生物（大果桉素B - G）。这些化合物结构密切相关，B - F的分子式为C₂₈H₄₀O₆，G的分子式为C₂₈H₃₈O₅。通过核磁共振分析对大果桉素B、D和G的结构进行了分析。
