“…The volatile extract of QLB exhibited a potential antimicrobial activity against Streptococcus pyogenes, compared to Streptococcus aureus, and Escherichia coli [14]. The antibacterial activity of the fatty acid methyl ester (FAME) extract of QL fruits was recorded against four bacterial stains namely; Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli from a range of 7.8 to 15.9 mm [15]. The extract of FAME showed dissimilar activity against different bacterial strains due to the chemical nature, antimicrobial agents, and their mode of action on different microorganism [28].…”

“…The fruit extract of QL revealed the presence of higher amount of saturated fatty acid compared to unsaturated fatty acid. The bark and fruit extract of QL possess antimicrobial activity [14,15]. The QL is used in traditional system of medicine, but still there are not many scientific reports to confirm its phytochemical activity and medicinal properties [16].…”

Background: Quercus leucotrichophora A. Camus (QL) belongs to the family Fagaceae, commonly known as Banj oak in the Garhwal region of Himalaya, where it is the principal source of fuel, fodder, and medicine. Methods: In the present study, GC-MS analysis has been performed for profiling the chemical composition of methanolic extracts of leaves and bark of QL. The antibacterial activity was evaluated by using the disk diffusion method against five bacterial strains. Results: Total 23 components in bark and 62 components in leaves extracts of QL were identified. The major components identified in the bark extracts were Linoleic acid (19.77%), Lupeol (17.91%), Epi-psi-Taraxastanonol (14.20), and cis-Vaccenic acid (13.10%), while others were present in relatively small amounts. For the leaves extract, the major components were Linoleic acid (17.09%), Simiarene (15.29%), Flavone 4′-oh, 5-oh,7-di-o-glucoside (15.26%), and D-Quinic acid (9.29%), respectively. As far as antibacterial assays are concerned, it was observed that both the extracts are active against most of the tested bacterial strains with the zone of inhibition ranging between 8.53 ± 0.50 to 19.07 ± 0.31 mm, respectively. Conclusion: The GC-MS results revealed the presence of several phytochemical compounds in leaves and bark of QL extract and are recommended as a plant of pharmaceutical importance. The antibacterial analysis showed that both the extracts (leaves and bark) of QL have antibacterial activity against all gram positive (S. aureus, B. subtilis and S. pyogenes) and gram negative (E. coli, P. aeruginosa) bacterial strains.

“…The FAMEs were active against E. coli, S. aureus showing 10-16 mm inhibition zone using agar well diffusion method. [18]. The FAME extracts of these plants also had Linoleic acid (C18:2) as one of the major constituents.…”

“…It may as well be used to 3, mono-, di and unsaturated fatty acids in an oil. GC-MS on the other hand can be used to accurately determine the quantities of the individual fatty acids based on retention volumes, retention [18]. The FAME extracts of these plants also had Linoleic acid (C18:2) as one of the major constituents.…”

“…Lipid extraction from plants is usually carried out with organic solvents of different polarities (mainly n-hexane, CHCl 3 , CH 2 Cl 2 , EtOAc, EtOH, BuOH, MeOH, and their mixtures) ( Table 1). Liquid/liquid extractions or Soxhlet extraction are commonly performed to obtain total lipid extracts [54][55][56][57][58]. Instead of analyzing one lipid class or one lipid molecule, some studies have analyzed the total lipid extracts that were obtained by sequential extraction.…”

Antimicrobial Lipids from Plants and Marine Organisms: An Overview of the Current State-of-the-Art and Future Prospects

In the actual post-antibiotic era, novel ways of rethinking antimicrobial research approaches are more urgent than ever. Natural compounds with antimicrobial activity such as fatty acids and monoacylglycerols have been investigated for decades. Additionally, the interest in other lipid classes as antimicrobial agents is rising. This review provides an overview on the research about plant and marine lipids with potential antimicrobial activity, the methods for obtaining and analyzing these compounds, with emphasis on lipidomics, and future perspectives for bioprospection and applications for antimicrobial lipids. Lipid extracts or lipids isolated from higher plants, algae or marine invertebrates are promising molecules to inactivate a wide spectrum of microorganisms. These lipids include a variety of chemical structures. Present and future challenges in the research of antimicrobial lipids from natural origin are related to the investment and optimization of the analytical workflow based on lipidomics tools, complementary to the bioassay-guided fractionation, to identify the active compound(s). Also, further work is needed regarding the study of their mechanism of action, the structure–activity relationship, the synergistic effect with conventional antibiotics, and the eventual development of resistance to lipids, which, as far as is known, is unlikely.
