DAWIDAR, A.M. et al. Effect of photo-oxygenation on biological activities of some commercial egyptian essential oils. Rev. latinoam. quím [online]. 2010, vol.38, n.3, pp.168-179. ISSN 0370-5943.

The components of five common commercial Egyptian essential oils; caraway, cumin, basil, thyme, and rose oils, were identified using gas chromatography/ mass spectrometry (GC/MS) and Kovats retention index. For each oil the main components were reported. Their biological activities, including deoxyribonucleic acid (DNA) damage, protein cleavage, antioxidant, antimicrobial and anti-diabetic effect were tested. The effect of photo-oxygenation reaction on their biological activities, using UV-irradiation in the presence of singlet oxygen sensitizer was investigated.

Keywords : Essential oils; Caraway; Carum carvi; Cumin; Cuminum cyminum; Basil; Ocimum basilicum; Thyme; Thymus vulgaris; Rosa damascema; Free radical scavenging; DNA and protein cleavage; Antioxidants; Antimicrobial; Hypoglycaemia; Photo-oxygenation.
