摘要
从地不容块根中分得四种生物碱A、B、C、D,经UV,IR,~1H-NMR,^(13)C-NMR,HRMS等方法鉴定了它们的结构,分别是cepharanthine (A),1-curine (B),isochondodendrine (C),ushinsunine (D)。C,D系首次从该植物中获得。
Four isoquinotine atkatoids were isolated from the root tubers of Stephania epigaea growing wild in Sichuan Province. They were identified as cepharanthine(A), 1-curine(B), isochondodendrine (C), and ushinsunine(D) by means of UV, IR, ~1H-NMR, ^(13)C-NMR, and MS spectral analysis. C and D were isolated from this plant for the first time.
