Abstract: ResumoCaryocar coriaceum (Caryocaraceae), popularmente conhecida como pequi, é uma espécie endêmica da Chapada do Araripe, Ceará. Na medicina popular seu fruto é comumente utilizado para tratamento de infecções e inflamações, propriedades também demonstradas em modelos experimentais. Entretanto, existem poucos estudos sobre a folha desta planta. Dessa forma, objetivou-se investigar a toxicidade, as características fitoquímicas e a atividade antioxidante de extratos aquoso e etanólico de folhas do Caryocar cori… Show more

“…The aqueous extract of the leaves of the species, for example, showed the highest capacity in reducing DPPH, with an IC 50 value 15 times lower than ascorbic acid, a positive control [52]. Duavy et al [53] reported that, at concentrations of 100 and 250 µg/mL, the DPPH radical scavenging exhibited by C. coriaceum leaf and fruit peel extracts was similar to that found for ascorbic acid.…”

“…Concomitantly, a positive control group was prepared with aquamarine and potassium dichromate (K 2 Cr 2 O 7 ), and a negative control was prepared with aquamarine and Tween 80. The ethanolic and aqueous extracts of C. coriaceum leaves presented, in vivo, a high toxicity on A. salina nauplii, with LC 50 values of 14.9 and 18.5 µg/mL, respectively-more toxic than the positive control (potassium dichromate), whose LC 50 was 55.9 µg/mL [52]. However, when using Drosophila melanogaster as a model, these authors found no toxicity of the aqueous extract at the concentration of 5 mg/mL during 5 days of the experiment [50].…”

“…It is rich in unsaturated, fatty acids and antioxidant components such as vitamins A and E (Sena et al, 2010). The leaves of C. coriaceum present antioxidant activity associated with tannins, phenols and xanthones (Duavy et al, 2012). In a hydroalcoholic leave extract, which demonstrated anti-inflammatory activity on mice skin inflammation models, the main phytochemicals were found to be chlorogenic acid, rutin, quercetin and lower concentrations of caffeic and gallic acids (Araruna et al, 2014).…”
