The expansion of orange production and the installation of agro-industries mitigate the need for waste utilization. This study investigated the use of residual orange peels for essential oil extraction and evaluation of their potential biological activity. The essential oil (OECL) was obtained from the Valência cultivar (Citrus sinensis L.), acquired in the municipality of Jerônimo Monteiro, Brazil. The fresh peels were quantified for moisture and essential oil content. The OECL was characterized regarding its physical (density and refractive index), chemical (qualitative/quantitative composition) and biological (antioxidant activity, phytotoxicity and cytotoxicity) attributes. The peels had 61.5% moisture and 0.9% essential oil, which had a density = 0.8572 g cm-3 and refractive index = 1.4712, having in its composition: Limonene (96.37%), Linalool (2.26%) and β-Pinene (1.37%). Among the biological activities evaluated, the strong antioxidant character stands out, with an effective concentration of 89 mg mL-1 for scavenging 50% of the free radical 2,2-diphenyl-1-picrylhydrazyl. In the in vitro phytotoxicity test, with Lactuca sativa,it was found that 30 mg mL-1 of OECL did not significantly alter the germination process or root growth, but reduced leaflet emission by 90%. In the in vitro cytotoxicity assay, 30 mg mL-1 of OECL did not affect the viability of Saccharomyces cerevisiaecell growth, but reduced its enzymatic activity by 30%. The exploration of OECL appears promising in terms of yield and biological activities, requiring more in-depth studies of selectivity and mechanisms of action.Downloads
