MOREIRA, Rafael Y.O. et al. Anthraquinones and naphtoquinones from the bark of Tectona grandis (Verbenaceae) reforestation specimen. Rev. bras. farmacogn. [online]. 2006, vol.16, n.3, pp. 392-396. ISSN 0102-695X.  http://dx.doi.org/10.1590/S0102-695X2006000300017.

The hexane extract of the bark of Tectona grandis (Verbenaceae) afforded two anthraquinones and two naphtoquinones. Their caracterizations were obtained through NMR spectroscopic techniques. This is the first phytochemical study of the bark of Tectona grandis reforestation specimen in Brazil. The main interest in this work is proving the presence of tectoquinone in reforestation specimen.
