Abstract
Essential oils from leaves of E. citriodora and E. torelliana pure species and E. citriodora x E. torelliana hybrids, obtained by hydrodistillation, were analyzed by GC and GC/MS. Six oil samples of E. citriodora showed two main constituents (citronellal 57.1–75.4% and citronellol 8–11%) out of 64 identified constituents (> 0.1%). Nine oil samples from E. torelliana contained 78 constituents (> 0.1%) with various main constituents: α-pinene (20.3–78.1%), globu- lol (20–26%) and citronellyl acetate (55.5%). Six oil samples of E. citriodora x E. torelliana hybrids were of a citronel- lal/citronellol chemical type (66–76%), like E. citriodora, or α-pinene (24.3–49.5%), or citronellyl acetate (61.4%) chemical type, like E. torelliana.Keywords
