Effects of a nanoemulsion with Copaifera officinalis oleoresin against monogenean parasites of Colossoma macropomum: A Neotropical Serrasalmidae. Repositório Alice
VALENTIM, D. S. S.; DUARTE, J. L.; OLIVEIRA, A. E. M. F. M.; CRUZ, R. A. S.; CARVALHO, J. C. T.; SOLANS, C.; FERNANDES, C. P.; TAVARES-DIAS, M..
Monogeneans are ectoparasites that may cause losses in production and productivity in the aquaculture of Colossoma macropomum. Chemotherapeutics used in aquaculture usually have major adverse effects on fish; hence, the use of essential oils has been considered advantageous, but these are not soluble in water. Thus, the use of nanostructures to enhance water solubility of compounds and improve bioactivity may be very promising. This study investigated the antiparasitic activity of nanoemulsion prepared with Copaifera officinalis oleoresin (50, 100, 150, 200 and 300 mg/L), against monogenean parasites from the gills of C. macropomum. The particle size distribution and zeta potential suggested that a potentially kinetic stable system was generated. The...

Nanoemulsion from essential oil of Pterodon emarginatus (Fabaceae) shows in vitro efficacy against monogeneans of Colossoma macropomum (Pisces: Serrasalmidae). Repositório Alice
VALENTIM, D. S. S.; DUARTE, J. L.; OLIVEIRA, A. E. M. F. M.; CRUZ, R. A. S.; CARVALHO, J. C. T.; CONCEIÇÃO, E. C.; FERNANDES, C. P.; TAVARES-DIAS, M..
Outbreaks of diseases pose a major threat to sustainable aquaculture development worldwide. Application of herbal products to combat parasitic diseases provides an alternative approach for sustainable aquaculture. This study investigated the in vitro antiparasitic effects of an oil-in-water nanoemulsion prepared using the essential oil from Pterodon emarginatus, against monogeneans infesting Colossoma macropomum. Gill arches from C. macropomum (47.6 14.5 g and 13.5 1.4 cm) that were naturally parasitized by Anacanthorus spathulatus, Notozothecium janauachensis and Mymarothecium boegeri were immersed in different dispersions of the P. emarginatus nanoemulsions (0, 50, 100, 200, 400 and 600 mg/L). The major compounds presented in the essential oil of P....

Preparation of a nanoemulsion with Carapa guianensis Aublet (Meliaceae) oil by a low-energy/solvent-free method and evaluation of its preliminary residual larvicidal activity. Repositório Alice
JESUS, F. L. M.; ALMEIDA, F. B. de; DUARTE, J. L.; OLIVEIRA, A, E. M. F. M.; CRUZ, R. A. S.; SOUTO, R. N. P.; FERREIRA, R. M. A.; KELMANN, R. G.; CARVALHO, J. C. T.; LIRA-GUEDES, A. C.; GUEDES, M.; SOLAN, C.; FERNANDES, C. P..
Andiroba (Carapa guianensis) seeds are the source of an oil with a wide range of biological activities and ethnopharmacological uses. However, few studies have devoted attention to innovative formulations, including nanoemulsions.The present study aimed to obtain a colloidal system with the andiroba oil using a low-energy and organic-solvent-free method. Moreover, the preliminary residual larvicidal activity of the nanoemulsion against Aedes aegypti was evaluated.
