Introduction: The Algerian Dettrichia viscosa essential oil yield evolution during water distillation has been investigated as a function of grinding leaves.
Methods: GC/MS analysis helped to determine the extraction kinetics of the major components of this essential oil.
Results: The results show that there are two kinetic types. We have tried to correlate this kinetic type with the essential oil location in the vegetable material and chemical composition. The microscopic observations show that most of the essential oil is localized in parenchyma but there are some in glandular hairs.
Conclusion: The water distillation of grinding leaves offers important advantages over the whole leaves: shorter isolation times (50 min) each type of kinetics corresponds to the compound considered localized in endogenous or exogenous deposits.
