Abstract

The1H- and13C-NMR spectra of alaternin, aurantio-obtusin, chryso-obtusin, obtusin and 2-glucosyl obtusifolin isolated from the seeds ofCassia tora have been assigned based on HMBC, long-range HETCOR, fully1H-coupled13C-NMR, deuterium isotope experiment, and by comparison with the model compounds.
