Abstract

Two‐dimensional NMR techniques were used to obtain a complete proton spectral assignment of nervosin, a natural product with medicinal interest isolated from a Chinese herbal medicine. The full relaxation matrix analysis method was used to process the NOE matrix of nervosin. The three‐dimensional structure in solution was calculated by the combination of the WUPH and WUPH‐S methods, based on NMR experimental data, with molecular mechanics energy minimization calculation. The result indicated that the solution structure of nervosin is similar to the x‐ray structure.
