Physicochemical Indexes and Evaluation of Antioxidant, Antihemolytic and Antibacterial Activities of Citrus sinensis and Citrus limon Peel Essential Oils

In this study, the physicochemical indexes, phytochemical screening by thin layer chromatography of essential oils (EOs) obtained from C. limon L. and sinensis peels their antioxidant, antihemolyticand antibacterial activities were investigated. The highest yield (0.71%), density (0.918 ±0.05), refractive index (1.974±0.02), saponification value (186.11±1.13 mg KOH/g) where in limon, wherethe acid ( 0.45±0.2mg was for C sinensis. Eight six spots identified sisensis respectively using thin-layer (TLC). IC50 DPPH radical-scavenging activity 7.04 ±1.03 8.39 ± 0.9 µg/mL oils, respectively. EO also demonstrated better antihemolytic peroxide scavenging, 12.76± 0.6 14.26 ±0.3 oils. peel EOs showed, also, a higher effect on S. aureus E. coli with 20.5±0.2 11.5 ±0.01 mm, Our data showed that both inactive against P. aeruginosa.
