Total assignments of 1H and 13C NMR spectra of isocatalpanol and a derivative of tecomaquinone

Magn Reson Chem. 2005 Jul;43(7):582-4. doi: 10.1002/mrc.1582.

Abstract

Isocatalpanol and tecomaquinone I were obtained from roots of Lippia sidoides, a medicinal plant from northeast Brazil. Reduction of tecomaquinone I with NaBH4 yielded a new derivative. Structural elucidation was done on the basis of spectral data, mainly by high-field NMR and electron ionization mass spectrometry.
