<jats:p><jats:bold>The Elucidation of Taxine A from <jats:italic>Taxus baccata</jats:italic> L.</jats:bold><jats:p>The structure of taxine A, C<jats:sub>35</jats:sub>H<jats:sub>47</jats:sub>NO<jats:sub>10</jats:sub>, the crystalline alkaloid obtained by partition chromatography of the amorphous taxine isolated from <jats:italic>taxus baccata</jats:italic> L. was elucidated. Partial structures and functional groups were derived from proton and carbon‐13 NMR involving decoupling experiments. Full structure determination of the tricyclic diterpenoid backbone was achieved by single crystal <jats:italic>X</jats:italic>‐ray diffractometry. Bond distances and assignments of proton and carbon shifts are given.
