Structure determination of Aervins A-D, new coumaronochromone analogues from Aerva persica, by 1D and 2D NMR spectroscopy

Aervins A-D (1-4), four new coumaronochromone analogues have been isolated from the CHCl3-soluble fraction of the MeOH extract of the whole plant of Aerva persica. Their structures were assigned based on H-1 NMR, C-13 NMR spectra, DEPT, and by 2DNMR experiments. Copyright (C) 2009 John Wiley & Sons, Ltd.
