Two new lignans, wikstronoside B (1) and forsysesquinorlignan (2), were isolated from the fruits of Forsythia suspensa, along with two known sesquineolignans, hedyotol A and hedyotol C (3 and 4). The structures of new compounds were established via extensive spectroscopy techniques, including UV, IR, HRESIMS, NMR, and ECD. Compounds 3 and 4 were isolated from this plant for the first time. Their anti-inflammatory effects were evaluated via a detection model with LPS-induced murine macrophage RAW264.7 cells, and compound 3 showed a moderate activity.

连翘属植物果实中的两种新木脂素。

从连翘的果实中分离出两种新的木脂素，即维克茶苷B（1）和forsysesquinorlignan（2），以及两种已知的芝麻木脂素，七醇A和七醇C（3和4）。新化合物的结构是通过广泛的光谱技术建立的，包括UV，IR，HRESIMS，NMR和ECD。化合物3和4首次从该植物中分离出来。通过LPS诱导的鼠巨噬细胞RAW264.7细胞的检测模型评估了它们的抗炎作用，化合物3显示出中等活性。
