Antimicrobial and antioxidant activities of Cymbopogon schoenanthus (L.) spreng. essential oil, growing in Illizi - Algeria

Abstract

Hydrodistilled volatile oil obtained from the aerial parts of Cymbopogon schoenanthus cultivated near Illizi, Algeria, was analyzed by Gas Chromatography Mass Spectrometry (GC-MS) and Gas Chromatography -Flame Ionization Detector (GC-FID). More than twenty compounds were identified, representing 94.636% of the total oil. The major constituents of essential oil were piperitone (63.35%), β-eudesmol (9.305%) and elemol (6.915%). Isolated essential oil was tested for radical-scavenging ability using the stable 2,2-diphenylpicrylhydrazyl (DPPH) radical, the 2,2'-azino-bis (ABTS) radical and for reducing power ability with a test based on the reduction of ferric cations (FRAP). In all tests, oil did not show a prominent antioxidant activity. The screening of antimicrobial activity of oil was individually evaluated against representatives of gram-positive, gram-negative bacteria and fungi, using the agar diffusion method. All tested microorganisms were inhibited by the essential oil of C. schoenanthus.

Therapeutic potential of Cymbopogon schoenanthus (L.) developed into nanoparticle technology

“…Other compounds in camel grass include intermedeol (6.1-17.4%), δ-2carene (4.5-10.0%) and elemol (5.2-9.0%) (Pavlovic et al, 2017). Studies on camel grass from Algeria also obtained similar results showing a compound composition of piperitone (63.3%), eudesmol (9.3%), δ-2-carene (4.9%), and elemol (6.9%) (Naima et al, 2016). ) and α-terpineol (6.8-11.7%) (Khadri et al, 2008).…”

“…and α-terpineol (6.8-11.7%) (Khadri et al, 2008). Hence, this shows that chemical compounds obtained from camel grass can be influenced by geographical conditions, seasons, and time of harvest (Khadri et al, 2008;Ganjewala, 2009;Naima et al, 2016;Pavlovic et al, 2017).…”

“…Cymbopogon schoenanthus (L.) Spreng also registered strong antimicrobial activity in studies on inhibitory zonesagainst Enterococcus faecium (21±1.4 mm), Staphylococcus aureus (19.5±0.7 mm), Escherichia coli (15±1.4 mm), Salmonella typhimurium (10.5±0.7 mm), Streptococcus agalactiae (12.75±0.3 mm), and Candida albicans (12±1.4 mm) (Naima et al, 2016).…”

Safety assessment of Cymbopogon shoenanthus (L.) Spreng. (Poaceae) essential oils: Oral toxicity, dermal and eye irritancy investigations

“…and Rhyzopertha dominica F., two maize seeds pests. Previous investigations in several countries confirm that some plant essential oils not only repel insects but have contact and fumigant insecticidal actions against specific pests, and fungicidal actions against some important plant pathogens (Hellali et al, 2016;Isman, 2000;Sarac and Tunc, 1995). Therefore, essential oils of C. schoenanthus have been shown to present biological effects against Anopheles gambiae and Plutella xylostella at different life stages.…”

“…It has quasiubiquitous distribution in Burkina Faso, and even settles in environments apparently less favorable to plants. Like its ubiquitous distribution, the data from literature demonstrated that Cymbopogon species including C. schoenanthus possess various biological properties such as anti-bacterial (Hashim et al, 2017;Hellali et al, 2016), anti-diarrheal, anti-amoebic, anti-filarial, anti-fungal, antiinflammatory, anti-mutagenicity, anti-malarial, antioxidants (Hellali et al, 2016), hypoglycaemic (Dutta et al, 2016), and spasmolytic (Pavlović et al, 2017). Furthermore, studies by different researchers indicate the presence of several chemical groups such as tannins, saponins, saponin glycosides, flavonoids, alkaloids, triterpens, cardiac glycosides, glycosides, steroids and volatile oils in the plant (Pavlović et al, 2017;Amina et al, 2013).…”
