Essential Oil of Cami, a New Citrus Hybrid

Abstract

The chemical composition of the essential oil of a new Citrus hybrid, named Cami, obtained by crossbreeding the Mapo tangelo (Citrus deliciosa Ten. x C. paradisi Macf.) as male parent and the 50-15A-6 hybrid (C. clementina Hort. ex Tan. x C. deliciosa Ten.) as female parent, was analyzed by GC/MS and compared with those of its parents. In total, 51 components were fully characterized and grouped in six classes (monoterpene hydrocarbons, oxygenated monoterpenes, sesquiterpenes, aliphatic aldehydes, aliphatic alcohols, esters) for an easier comparison of all oils. Variations during the fruit development of the percentage of the six classes are also described. A statistical treatment by linear discriminant analysis (LDA) of the compositional data from GC analyses was also carried out. The peel essential oil of the new Citrus hybrid Cami shows compositional features resembling those of Mapo tangelo and Avana mandarin, but in an original and unique way, thus making it an interesting new Citrus essential oil.
