Daphnimacropodines A-D,Alkaloids from Daphniphyllum macropodum

摘要

Four new Daphniphyllum alkaloids,daphnimacropodines A-D(1-4),together with three known ones,daphnilactone B and daphnezomines H and I,were isolated from the fruits of Daphniphyllum macropodum.Their structures were determined by spectroscopic methods,especially 2D NMR techniques.
