Isocatalpanol and tecomaquinone I were obtained from roots of Lippia sidoides , a medicinal plant from northeast Brazil. Reduction of tecomaquinone I with NaBH 4 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.
