Nine new compounds, together with 16 known analogs, were isolated from the whole plants of Rehmannia chingii. The structures of compounds 1–9 were elucidated on the basis of their spectroscopic data and chemical evidence. In addition, the new compounds were tested for their hepatoprotective activities against APAP-induced HepG2 cell damage and their ability to inhibit LPS-induced nitric oxide production
从生地黄的整个植物中分离出九种新化合物以及16种已知类似物。化合物的结构1 - 9分别鉴定其光谱数据和化学证据的基础上。此外,测试了新化合物的抗APAP诱导的HepG2细胞损伤的肝保护活性,以及抑制鼠小胶质细胞BV2细胞系中LPS诱导的一氧化氮生成的能力。化合物2和5在10μM的浓度下对APAP诱导的HepG2细胞损伤表现出明显的肝保护活性,化合物4和9表现出对小胶质细胞炎症因子的中等抑制活性,IC 50值分别为3.51和7.11μM。
