Characterization of Essential Oil Components from Aromatic Plants that Grow Wild in the “Piana del Sele” (Salerno, Southern Italy) using Gas Chromatography-Mass Spectrometry

Abstract

Essential oils from Rosmarinus officinalis, Salvia officinalis, Thymus vulgaris, Melissa officinalis and Mentha spicata growing wild in the "Piana del Sele" (Salerno, Southern Italy) have been extracted by hydro-distillation, quantified and characterized by gas chromatography coupled with flame ionization detection (FID) and mass-spectrometry (MS). Sixty-nine compounds were identified and classified according to their chemical classes. The results showed that the composition of the essential oils was extremely variable and specific for each botanical species. Hydrocarbons were the most abundant class in all essential oils except for sage where aldehydes and ketones were the most representative compounds. Only for thyme was a higher content of alcohols found.

Klebsiella pneumoniae Planktonic and Biofilm Reduction by Different Plant Extracts: In Vitro Study

“…Pham et al reported that the monoterpene molecule has the ability to change the fluidity and the carrying of substances through the lipid bilayer. Thus, this change in the membrane permeability may have caused metabolism collapse and death of the microorganism [31–34]. The difference in susceptibility of the tested microorganism can be attributed to the rate at which the active components of the plant extracts seem to diffuse through the cell and into the phospholipids of cell membrane [35].…”
