• 개요

  A constituent of Taxus baccata, this alkaloid is amorphous and has [α]²⁰_D + 119° (CHC13). The hydrochloride is also amorphous with no definite melting point. The nitrate, however, can be crystallized from Et20-isopropanol, m.p. 190°C. The base yields a diacetyl derivative which, although amorphous when obtained from aqueous solution, m.p. 92°C, forms colourless crystals from EtOH, m.p. 161.5°C. This latter base has [α]²⁰_Do + 106.7° (c 2.0, CHC1 3) and gives a crystalline hydrochloride from EtOH containing solvent of crystallization, m.p. 168-l70°C; nitrate as colourless needles or plates from EtOH, m.p. 141.5°C and the methiodide, m.p. 197°C. The structure of the alkaloid is that of Taxine I (q.v.) minus two acetyl groups.
