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

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 ma...

Description
Summary: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. Copyright © 2005 John Wiley & Sons, Ltd.
