title: Pordamacrines A and B, alkaloids from Daphniphyllum macropodum.
abstract: The new Daphniphyllum alkaloids, pordamacrines A (1) and B (2), have been isolated from the leaves of Daphniphyllum macropodum, and their structures were elucidated on the basis of interpretation of spectroscopic data and by the single-crystal X-ray diffraction analysis of 2. Pordamacrines A (1) and B (2) exhibited moderate vasorelaxant effects on the rat aorta.
