Popis: Two new Cephalotaxus alkaloids, (±)-cephaloliverine A (1) and cephalolancine A (2) were isolated from Cephalotaxus oliveri and Cephalotaxus lanceolata respectively. Their structures were determined on the basis of spectroscopic techniques including NMR, IR, UV, mass spectrometry, and X-ray diffraction. Cephalolancine A (2) features a new skeleton-type. The discovery of these alkaloids provides biogenetic evidences of the formation of Cephalotaxus alkaloids.
