Product Abstract
Citriodora or Lemon eucalyptus is a jewel in the crown of the Eucalyptus family, Myrtaceae. With a revivifying and invigorating aroma of lemon and eucalyptus, this lemon-scented eucalyptus oil is used in fixing feelings of abandonment and mental agitation along with poor concentration and confusions. The essential oil of Citriodora is extracted from the elongated leaves of the Lemon-scented gum tree
Harvesting/Extraction Information
The steam and water distillation of leaves of Citriodora was modeled using a complete 2n factorial plan. Eight experiments were carried out, with three easily interpretable variables, for steam distillation and for a first degree polynomial model. The average essential oil yield was 2.3%. Positive effects decreased in the order: duration of the extraction, heating power and state of division of the plant. Interactions were negligible. Extraction conditions had no practical impact on citronellal content
