CHEMICAL COMPOSITION BY GC-MS, ANTIOXIDANT AND ANTIBACTERIAL ACTIVITIES OF PEELS AND LEAVES EXTRACTS FROM Citrus limon, Citrus sinensis AND Citrus reticulata

Citrus family especially lemon, mandarin and orange, have reached important attention due to the presence of several components with different therapeutic properties. The leaves and peels of non-polar extracts from bio-citrus cultivars were investigated for phytochemical analysis, antibacterial and antioxidant capacity. The DPPH (1,1-Diphenyl-2-picrylhydrazyl) activity and phosphommolybdenum antioxidant effect values from leaves and peels ranged from 0 to 12.79% and 0.006 to 0.14 mg/ml AAeq respectively. Results showed significant differences in antioxidant properties of leaves and peels extracts. The leaves of mandarin exhibited a higher antioxidant activity than the other extracts from lemon and orange. Among different components identified from the organic extracts, limonene, myrcene, and benzopyran were major components in all samples.
