“…Isoeugenol is a chemical isomer of eugenol, which is known for its antifungal, antibacterial and antioxidant properties (Dubey et al, 2000;Lemos et al, 2005;Pereira and Maia, 2007), and which is broadly used in the perfume, cosmetic and pharmaceutical industries (Oliveira et al, 2008;Costa et al, 2010). Furthermore, eugenol and isoeugenol obtained from essential oils are viable economical sources for the production of valine by bioconversion (Daugsch and Pastore, 2005;Zhao et al, 2006;Ashengroph et al, 2012). Thus, considering the elevated concentration of isoeugenol in leaves and inflorescences even under water deficit, O. africanum may hold potential as a source of eugenol and vanillin for industry.…”

Mechanisms by which plants acclimatize to water deficit conditions can affect development and, especially in aromatic plants, the essential oil synthesis. To evaluate the effects of water deficit on Ocimum africanum, seedlings were exposed to water levels corresponding to 100, 80, 70 and 60% of the substrate field capacity. The different watering regimes corresponded to predawn water potentials of -0.5, -0.9, -1.6 and -1.9 MPa, respectively. Decreased stomatal conductance and increased glandular and tector trichome density were observed under water deficit. In addition, reductions in leaf gas exchange and water consumption under water deficit led to decreased plant height, numbers of leaves and inflorescences, and total biomass production. As a result, lower essential oil yield and water use efficiency for biomass production occurred in the -1.9 MPa treatment. The content and production efficiency of essential oil (quantity of oil produced per unit water consumed) were higher in the -0.9 and -1.6 MPa treatments. There were no significant differences among treatments in the chemical composition of essential oil, and the major component of essential oil in leaves and inflorescences was isoeugenol in all treatments. The 80% field capacity watering regime (branch water potential of -0.9 MPa) was best for the growth and production of essential oil in O. africanum, for the cultivation of aromatic plant under drought economically viable in the semi-arid climatic regions.

“…O ácido ferúlico mostra-se promissor para formulação de produtos hidratantes anti-idade, maquiagens, tinturas capilares e, principalmente, filtros solares onde o composto pode atuar pelos seus mecanismos fotoprotetores e ainda inibir a fotodegradação (Peres, 2015). Além disso, pode ser usado para produção de vanilina natural (Daugsch & Pastore, 2005).…”

“…Estudos apontam o seu potencial como antimutagênico, antioxidante, conservante e antimicrobiano, logo, é também bastante usada na fabricação de produtos farmacêuticos, tais como: papaverina, L-dopa, L-metildopa e agentes antimicrobianos (Daugsch & Pastore, 2005;Cardoso, 2013;Fernandes, 2018).…”
