CHEMICAL STUDIES ON THE ALKALOIDS FROM HU-MANTENG (GELSEMIUM ELEGANS BENTH.) Ⅲ.ELUCIDATION OF THE STRUCTURES OF HUMANTENINE AND HUMANTENIRINE

    摘要
  • Abstract: Two new oxindole alkaloids, humantenine and humantenirine, have been isolated from the root of Hu-Man-Teng (Gelsemium elegans Benth.) (Loganiaceae). Based on spectral data (UV, IR, 1H NMR, 13C NMR and MS) and preparation of derivatives, the structures of humantenine and humantenirine were elucidated as (Ⅰ) and (Ⅱ), respectively. The former was confirmed by single-crystal X-ray analysis of its hydrobromide.
