CHEMICAL STUDIES ON THE ALKALOIDS FROM HU-MAN-TENG (GELSEMIUM ELEGANS BANTH.)——II. THE STRUCTURE OF HUMANTENDINE
-
Abstract: A new oxindole alkaloid, humantendine, was isolated from the root of Hu-Man-Teng (Gelsemium elegans Banth.). On the basis of spectroscopic analysis (UV, IR, MS, PMR and 13CNMR) of humantendine and its derivatives the structure of humantendine was confirmed as(Ⅰ).
