Three new lignanamides, that is, a new lignanamide (), and a pair of enantiomers ( and ) were isolated from the EtOAc-soluble fraction of an EtOH extract of the root of . The structures of these new compounds, including their absolute configuration, were established on the basis of HR-ESI-MS, NMR spectroscopic data and quantum chemical ECD calculations. Compound showed significant anti-inflammatory activity in LPS-induced RAW 264.7 macrophages with the IC value of 10.77 ± 2.14 μM, comparing to that of positive control quercetin (17.21 ± 0.50 μM).
从 的根的 EtOH 提取物的 EtOAc 可溶部分分离得到三种新的木脂酰胺,即一种新的木脂酰胺()和一对对映异构体(和)。这些新化合物的结构,包括它们的绝对构型,是基于高分辨电喷雾电离质谱(HR-ESI-MS)、NMR 波谱数据和量子化学ECD 计算确定的。化合物在 LPS 诱导的 RAW 264.7 巨噬细胞中显示出显著的抗炎活性,IC 值为 10.77±2.14 μM,与阳性对照槲皮素(17.21±0.50 μM)相比。
