What is Isolation and structural elucidation of griffithine by 1D and 2D NMR techniques about?
## Abstract The isolation and structure elucidation of a novel dimeric alkaloid, griffithine, from the leafy shoots of __Sophora griffithii__ Stock (Papilionaceae) is described. The alkaloid possesses a 12‐membered ring system formed by the linking of C‐10 and C‐10′ of the alkaloid with the N‐1 and N‐1′ atoms, respectively. The structure was established on the basis of extensive 1D and 2D NMR studies. The relative stereochemistry at the chiral centres was determined by NOE difference experiments. 10‐Oxosparteine was isolated for the first time from the leafy shoots of __Sophora griffithii__.
