The effect of addition of dimethylimidazolium dimethylphosphate in the maceration step, which precedes hydrodistillation, on yield and composition of the essential oil of cinnamon dried bark and cortex has been evaluated. The use of a 1:1 ionic liquid (IL)-water mixture permitted the improvement of the essential oil yield by about 200%. Moreover, an appreciable change in the composition of the essential oils when the IL was added was observed.

Abstract
The effect of addition of dimethylimidazolium dimethylphosphate in the maceration step, which precedes hydrodistillation, on yield and composition of the essential oil of cinnamon dried bark and cortex has been evaluated. The use of a 1:1 ionic liquid (IL)-water mixture permitted the improvement of the essential oil yield by about 200%. Moreover, an appreciable change in the composition of the essential oils when the IL was added was observed. Noteworthy, an enrichment in (E)-cinnamaldehyde, the active metabolite of cinnamon essential oil, attributable to the degradation of lignin by the IL accompanied the impressive increase in essential oil yield.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
