The present study aimed (1) to investigate the chemical composition as well as the anti‐inflammatory properties and in vitro antioxidant activity of Citrus aurantium peel essential oil ( p EO Ca ) and (2) to evaluate its potential effect in vivo. The main results showed that the major components of p EO Ca are Limonene and Linalool. Additionally, DPPH scavenging ability and β‐carotene bleaching inhibition tests confirmed the antioxidant capacity of p EO Ca . Our oil reduced the production of NO by LPS‐stimulated RAW264,7 macrophages in a concentration‐dependent. This inhibition occurred at a transcriptional level. p EO Ca in CCl 4 treated rats alleviated hepatotoxicity as monitored by the improvement of hepatic oxidative stress biomarkers levels plasma biochemical parameters, and DNA molecule aspect. Furthermore, the mRNA gene expression of Cu‐Zn SOD, CAT, and GPx increased under CCl 4 + p EO Ca exposure to reach the same value to the control. Similarly, antioxidant activities of these three enzymes changed in accordance with the mRNA levels. These results were confirmed by the histological results. It seems obvious that the treatment with p EO Ca prevented liver damage induced by CCl 4 , thus preventing the harmful effects of free radicals.
