afforded four new oleuropeic acid derivatives (1–4), named as elsholblanosides A−D, respectively, together with 11 known compounds (5–15). Their structures were determined based on extensive analyses of HR-ESI-MS, 1D and 2D NMR, and ECD spectra. Compounds 1–4 and 14 showed moderate NO production inhibition in LPS-activated RAW264.7 cells with their IC50 values ranging from 23.2 to 86.33 μM, compared
香薷地上部分的植物化学调查。提供了四种新的橄榄酸衍生物 ( 1 – 4 ),分别命名为 elsholblanosides A−D,以及 11 种已知化合物 ( 5 – 15 )。它们的结构是根据 HR-ESI-MS、1D 和 2D NMR 以及 ECD 光谱的广泛分析确定的。化合物1-4和14在LPS激活的RAW264.7细胞中表现出中等程度的NO产生抑制作用,其IC 50值范围为23.2至86.33 μM ,而阳性对照化合物地塞米松的IC 50值为16.9 μM。
