Resumo: The essential oils, isolated by hydrodistillation, from the flowers of different cultivars of Citrus sinensis (L.) Osbeck (Cs) and Citrus clementina Hort. Ex Tan. (Cc) collected at different harvesting times, were analyzed by GC and GC-MS. All the samples studied afforded yellowish oil which yields ranged from 0.05 to 0.08 % (v/w). The monoterpene fraction dominated both oils (66-91%), being the monoterpene hydrocarbons the main components of this fraction (45-69%). Sabinene (31-48%), linalool (15-32%) and limonene (4-10%) dominated both Cs and Cc oils. trans-Nerolidol was the major sesquiterpene component, attaining 3-10%. Cluster analysis of the essential oil composition from the twelve samples studied, confirmed a major chemical homogeneity (Scorr>0.95) despite the fact of having used different periods of hydrodistillation, different harvesting times and being flowers of two different Citrus species.
