Abstract Fourteen isopimarane diterpenoids (1–14) were isolated from the rhizomes of Kaempferia galanga, including four new compounds (1–4). The isolated secondary metabolites were identified through analysis of spectroscopic (1 D and 2 D NMR) and mass spectrometric data, together with X-ray diffraction studies. Compounds 4–5, 7–11, and 13 showed strong antimalarial activities, with IC50 values in
摘要 从高良姜的根茎中分离出十四种异海松烷二萜类化合物( 1 – 14 ) ,其中包括四种新化合物( 1 – 4 )。通过分析光谱(1 D 和 2 D NMR)和质谱数据,以及 X 射线衍射研究,确定了分离的次级代谢物。化合物4 – 5、7 – 11和13显示出很强的抗疟活性,IC 50值在 1.46–3.99 μ g/mL范围内 。此外,化合物4、5、8和化合物12显示出对 KB 细胞系的细胞毒性,IC 50值在 6.13–38.2 μ g/mL范围内 ,而化合物4、5和12显示出对 MCF-7 细胞系的细胞毒性,IC 50值在 11.75–47.4 范围内 微克/毫升。最终,分离出的化合物针对六种细菌菌株和结核分枝杆菌进行了筛选,显示出弱到中等的活性。
