Four new sesquiterpenoids，including three nor-cinalbicane type sesquiterpenoids, named Jasminol A, G, H (1-3) and one eremophilene-type sesquiterpenoid, named Jasminol B (4) together with nine known compounds (5-13) were isolated from the stems of Jasminum officinale L. The structures of new compound were elucidated on the base of IR, HR-ESI-MS, 1D NMR, 2D NMR and DEPT analysis, and the absolute configurations were determined by single-crystal X-ray diffraction analysis. In addition, the anti-inflammatory activity of isolated compounds was evaluated using lipopolysaccharide (LPS)-induced murine macrophage RAW264.7, and compounds 1-4 exhibited a moderate inhibition of LPS-induced nitric oxide (NO) production in RAW264.7 cells with IC values of 20.56 ± 1.31, 30.12 ± 0.89, 30.35 ± 2.72 and 31.60 ± 1.69 μM, respectively, and CC values >200 uM.
从木樨科素馨属植物迎春花 Jasminum officinale L. 的茎中分离得到了 4 个新的倍半萜类化合物，包括 3 个属于诺古卡烷型倍半萜的化合物 Jasminol A、G、H（1-3）和 1 个属于埃雷莫芬烷型倍半萜的化合物 Jasminol B（4），以及 9 个已知化合物（5-13）。根据 IR、HR-ESI-MS、1D NMR、2D NMR 和 DEPT 分析，确定了新化合物的结构，并通过单晶 X 射线衍射分析确定了其绝对构型。此外，还评价了分离得到的化合物对脂多糖（LPS）诱导的小鼠巨噬细胞 RAW264.7 的抗炎活性，化合物 1-4 对 LPS 诱导的 RAW264.7 细胞中一氧化氮（NO）的产生具有中等抑制作用，IC50 值分别为 20.56±1.31、30.12±0.89、30.35±2.72 和 31.60±1.69 μM，CC50 值均大于 200 μM。
