The quality of essential oils (EOs) was dependent on the optimised methods of drying. The highest yield of EOs was noted in plants elicited with 0.1% yeast extract (YE) and dried with the traditional method (1.4 mL 100 g dw−1); it was over twice as high as the yield of the control sample (0.58 mL 100 g dw−1). (Z)-ligustilide, α-terpinyl acetate and β-phellandrene were the main compounds identified in the samples. The most effective antioxidant activity was exhibited by the sample obtained from plants elicited with 0.1% YE and subjected to freeze-drying. The highest RP and LPO inhibition were determined in samples obtained from plants subjected to jasmonic acid (JA) elicitation and freeze-drying (1.85 and 1.02 μL mL−1 respectively). The use of 0.1% JA and microwave-drying was the most effective for inhibition of LOXI activity. The highest acetylcholinesterase inhibition was noted in the freeze-dried sample obtained from plants elicited with YE (86.39 kIU mL−1). The samples exhibited the highest antibacterial activity against L. monocytogenes BBA-2660.
