  1. aLRIexp – experimental linear retention index on SLB-5MS column
  2. The volatile compounds are expressed in % values (average of three replicated injections).
  3. bThe relative concentrations were chosen based on the calculation as if the cells were treated with 200 μL essential oil
  4. * indicates a coelution on SLB-5 ms column
