Three new abietane-type diterpenoids, named callicapoic acid M3 (), callicapoic acid M4 () and callicapoic acid M5 (), were isolated from the Vahl. Their structures were established by spectroscopic techniques (IR, UV, MS, 1D and 2D NMR). All the isolated three compounds were evaluated for inhibitory activity on NO production in LPS-activated RAW 264.7 macrophage cells by using MTT assays. Compounds , and showed potent inhibitory activity, with inhibition rates of 34.47-40.13%.
从菊科植物Vahl中分离出三种新的枞酸型二萜类化合物,分别命名为卡里卡波酸M3()、卡里卡波酸M4()和卡里卡波酸M5()。通过光谱技术(红外光谱、紫外光谱、质谱、一维和二维核磁共振)确定了它们的结构。采用MTT法对所有分离出的三种化合物进行了LPS激活的RAW 264.7巨噬细胞中NO生成抑制活性的评估。化合物、和表现出较强的抑制活性,抑制率为34.47 - 40.13%。
