Cananga odorata Hook. fil. et Thomson (belonging to the family of the Annonaceae) is an evergreen tree indigenous China, Burma, Thailand, Indonesia and the Philippines. This species has been used in folk medicine for the treatment of malaria, tinea infections and fever.The essential oils of C. odorata are mostly obtained by steam distillation of fresh mature flowers and rarely by solvent extraction In these conventional isolation processes,the mass transfer is limited by molecular diffusion. These time-consuming processes are characterized by low isolation
efficiency, loss of volatile compounds, thermal or hydrolytic degradation of the unsaturated compounds and toxic solvent residue in the extract
