An evaluation on the chemical and biological activities of Citrus spp. cultivated in Egypt

Dodi Emam Sawiris


A comparative study of the essential oils isolated from the leaf and fruit peel of Cleopatra mandarin (Citrus reshni) was carried out using gas liquid chromatography (GLC) and GLC/mass analysis (MS). Over 140 components were observed in GLC/MS, of which 123 could be identified. 112 compounds were quantitatively analyzed in the leaf oil with linalool as a major component. The total identified components in the fruit peel oil were 69 and limonene was the most prominent. Cleopatra mandarin volatile components showed high anti-inflammatory activity represented by its effect on tumour necrosis factor-α and nitric oxide. They also showed significant anti-microbial activities against most common Gram positive and Gram negative bacteria and some fungi.
