A Spectroscopic Study on Tautomerism of Selaginellins from Selaginella

A Spectroscopic Study on Tautomerism of Selaginellins from Selaginella

Ultraviolet-visible and nuclear magnetic resonance (NMR) spectroscopy was used to investigate the effects of pH, solvent and temperature on the tautomeric equilibrium of selaginellins from Selaginella. The results demonstrated that the tautomerism of selaginellins could be catalyzed by acid, base an...
