Antimicrobial action of the essential oil of Lippia gracilis Schauer

Abstract

Antimicrobial activity of the essential oil (EO) of Lippia gracilis

In vitro antifungal activity and mechanism of essential oil from fennel (Foeniculum vulgare L.) on dermatophyte species

“…The inhibition of mycelial growth of dermatophyte strains (T. tonsurans 10-0400, T. mentagrophytes 10-0060, M. gypseum 44693-1, T. rubrum ATCC 40051) by FSEO was determined with a method modified from that reported by de Albuquerque et al (2006). Aliquots of FSEO separately dissolved in 1.0 ml 0.1 % (v/v) Tween 20 were pipetted aseptically to glass Petri dishes containing 9.0 ml melted potato dextrose agar (PDA) to make the requisite concentrations of 0.019, 0.039, 0.078, 0.156, 0.312 and 0.625 ml ml 21 .…”

Effect of salt stress on the growth of Lippia gracilis Schauer and on the quality of its essential oil

“…One of the most widely used species is Lippia gracilis Schauer, known locally as Alecrim-da-Chapada, which is a native to the caatinga. The species produces an essential oil containing phytochemicals of proven antimicrobial effectiveness, in varying proportions (Albuquerque et al 2006;Oliveira et al 2008;Motta-Neto et al 2010).…”

Secondary Metabolites from an Infusion of Lippia gracilis Schauer Using the LC‑DAD-SPE/NMR Hyphenation Technique

“…1 Lippia gracilis Schauer (Verbenaceae) is a species that is included in this group once, to our knowledge, there is only one report about its non-volatile constituents, 2 while most reports are focused on studies on the composition of essential oils and their biological activities. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] The genus Lippia comprises approximately 200 species of herbs, shrubs and small trees, distributed throughout the South and Central America countries and tropical Africa. 22 The species L. gracilis Schauer is an endemic aromatic plant to the Brazilian Northeast normally found in the states of Bahia, Sergipe and Piauí.…”

“…Previous chemical investigations into the L. gracilis Schauer species are focused on its volatile constituents where thymol and carvacrol, which showed strong antimicrobial activity against fungi and bacteria, are the main components. 12 The chemical composition of the volatile compounds shows quantitative variations of the The literature only reports one study on the isolation of fixed constituents from the methanolic extract from the leaves of L. gracilis Schauer, which presented the isolation of the known flavanone: naringenin.2 Two other works only show the characterization of teas and methanolic extracts from L. gracilis Schauer genotypes cultivated in the rural campus of the Federal University of Sergipe and originated from the states of Sergipe and Bahia (Brazil) by liquid chromatography with diode array detector (LC-DAD) combined with chemometric analysis. 22,26 In view of the above, in this study, we report the application of the LC-DAD-SPE/NMR (LC-DAD-solid phase extraction/nuclear magnetic resonance) hyphenation technique to isolate and identify some of the constituents of infusions of the leaves of a genotype of L. gracilis Schauer.…”
