Chemical variability and antioxidant activity of Cedrus atlantica Manetti essential oils isolated from wood tar and sawdust

The present research was devoted to evaluating the effect of provenance and wood pyrolysis process on the phytochemical and antioxidant activity of essential oils extracted from sawdust and tar of Cedrus atlantica Manetti of Morocco. The essential oils were obtained by hydro-distillation from Cedar...
