Exploring natural essential oil components and antibacterial activity of solvent extracts from twelve Perilla frutescens L. Genotypes

The essential oil obtained by hydrodistillation method from plants of three varieties Agastache aurantiaca, cultivated on the Republic of Belarus were investigated. Some morphobiometric parameters of plants 'Tango', 'Apricot Sprite' and 'Fragrant Delight' and oil yields were determined. Using the technique of gas-liquid chromatography essential oil components were identified and determined. The main components of the essential oil from 'Tango' and 'Fragrant Delight' plants were menton (~ 53 and ~ 65 v/v % respectively) and pulegon (~ 36 and ~ 25 v/v % respectively). The samples of 'Apricot' Sprite' essential oil were rich in isomentone (~ 46 v/v %) and pulegon (~ 41 v/v %). All tested essential oils contained (+)-menton and (+)-pulegon enantiomeric forms only. The antibacterial activity of dimethylsulfoxide and ethanolic essential oil solutions against Staphylococcus aureus, Salmonella alony, Bacillus subtilis, Clostridium sp., Escherichia coli Hfr H, Pseudomonas aeruginosa was proved. Ethanol solutions of essential oils at the concentrations 0.001–0.1 v/v % had significant bactericidal activity. A correlation between the composition of the essential oil and their antibacterial properties was established.

Oil Components

We have hydrodistilled the essential oil (EO) from the aerial parts of the Bhutanese medicinal plant, Pleurospermum amabile using a Clevenger apparatus and evaluated this EO by GC/GC-MS and NMR analysis followed by testing for bioactivity. The GC-MS analysis identified 52 compounds with ( E)-isomyristicin as a major component (32.2%). Repeated purification yielded four compounds; ( E)-isomyristicin (1), ( E)-isoapiol (2), methyl eugenol (3) and ( E)-isoelemicin (4). Compound 2 and the mother EO showed the best antiplasmodial activity against the Plasmodium falciparum strains, TM4/8.2 (chloroquine and antifolate sensitive) and K1CB1 (multidrug resistant). They exhibited mild antibacterial activity against Bacillus subtilis. None of the test samples showed cytotoxicity.
