Composition and antimicrobial activity ofEquisetum arvense L. essential oil

Abstract

The volatile constituents of the sterile stems of Equisetum arvense L. (Equisetaceae) were investigated for the first time using GC, GC/MS and (13)C-NMR. Twenty-five compounds were identified. Hexahydrofarnesyl acetone (18.34%), cis-geranyl acetone (13.74%), thymol (12.09%) and trans-phytol (10.06%) were the major constituents. A disk diffusion method was used for the evaluation of the antimicrobial activity of this oil against a panel of microorganisms (bacteria: Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Salmonella enteritidis; fungi: Aspergillus niger and Candida albicans). The 1:10 dilution of the essential oil of Equisetum arvense L. was shown to possess a broad spectrum of a very strong antimicrobial activity against all tested strains.

Anticandidal effect of endophytic bacteria isolated from Equisetum arvense L. against Candida albicans and Candida glabrata

“…To date, 25 compounds with antimicrobial activities have been identified in essential oil obtained from the aerial parts of the plant 25,35 . Moreover, the extract of E. arvense L. at a concentration of 50 mg/mL was found to be 100% effective against C. albicans and C. glabrata 26 . There are also reports of propylene glycol extract of E. arvense and mixture of extract and formulated gel having anticandidal and antibacterial activity 36 .…”

“…Additionally, E. arvense extract has been used in traditional medicine for the treatment of various health conditions, including as an astringent for tissue healing and for curing of kidney stones. The herbal extracts of E. arvense L. possess antimicrobial, anti-inflammatory and anticancer effects [24][25][26][27][28][29][30] . The essential oil of E. arvense exerted antibacterial and anticandidal potentials [31][32][33] .…”

Comparative study on the essential oils of Myosotis arvensis and Myosotis palustris herbs (Boraginaceae)

“…It has already been shown that essential oils may, despite their small amounts, contribute to the therapeutic activities of the plants (Radulović et al 2006). Among the major biological activities of essential oils antibacterial, antifungal and anti-inflammatory properties are mentioned.…”
