ABATRACT Nine compounds, five phenolic glycosides (1, 2, 4–6), three phenylpropanoids (7–9), and a furanone glycoside (3), were isolated from aqueous soluble extract of the dried roots of Anemone chinensis Bunge. The structures of new compounds (1–4) were elucidated by comprehensive spectroscopic data analysis as well as chemical evidence. Pulsatillanin A (1) demonstrated significant antioxidant effects
ABATRACT 从海葵干燥根的水溶性提取物中分离出九种化合物,五种酚苷(1、2、4-6 )、三种苯丙烷(7-9)和呋喃酮苷(3 ) 。通过综合光谱数据分析和化学证据阐明了新化合物 ( 1-4 ) 的结构。白头翁素 A ( 1) 在 DPPH 测定中通过清除自由基表现出显着的抗氧化作用,并通过减少 ROS 产生、增强抗氧化酶 SOD 活性、以剂量依赖性方式补充耗尽的 GSH 来缓解 LPS 诱导的 RAW 264.7 细胞中的氧化应激。Western印迹分析显示,1通过激活Nrf2信号通路显示出抗氧化活性。
