Abstract

The effect of drying on the chemical composition and antioxidant activity of the essential oil obtained from peels of Citrus. acida (lime) C. mandarin (grape) and C. reticulata (tangerine) was examined. The result of the chemical composition as determined by gas chromatography/ mass spectrometry showed that monoterpene hydrocarbons oxygenated monoterpene hydrocarbons and sesquiterpenes are the major terpenes found in the essential oils of both dried and fresh peels of the samples. All the dried samples had higher percentage of one terpene group or the other than their fresh counterpart. The percentage of oxygenated monoterpenes ranged between 7.03 “ 21.71 with fresh lime peels having the highest percentage and fresh tangerine peels the lowest percentage. All samples possessed antioxidant activity as evaluated by 1 1- diphenyl-2-picryhydrazyl (DPPH) radical method 2 2-azinobis (3-ethylbenzothiazoline-6- sulfunate) (ABTS ) Hydroxyl radical and ferric reducing property (FRAP). Dried tangerine peels showed the highest ABTS radical scavenging ability when compared with trolox. The results showed that drying had effect on the chemical composition as well as the antioxidant activity of the samples. Peels of these citrus species can be of importance in medicine cosmetic and pharmaceutical industry due to their good antioxidant ability.
