Cymbopogon citratus(DC) Stapf Volatile Oil from South - West, Nigeria

Abstract

Chemical analysis of the volatile oil of Cymbopogon citratus and its antibacterial effects were investigated. Chemical analysis of the C. citratus oil was determined using Gas Chromatograph-Mass Spectrometry technique. Out of 47 peaks (representing 97.36 % of the total oil), 37 constituents were identified representing 90.86 % of the total oil constituents. The major constituents were geranial (40.9 %), neral (29.7 %), myrcene (11.3 %), linalool (1.7 %) and geranylacetate (1.6 %). The oil was examined against six bacteria; Escherichia coli, Pseudomonas aeruginosa, Salmonella typhimurium, Klebsiella pneumonia, Serratia marcescens and Staphlycoccus aureus. It was found that C. citratus inhibited the growth of all tested microorganism.

Chemical Composition of the Essential Oils ofCymbopogon citratus(DC.) Stapf Grown in Three Locations in South India

“…Also the oil has the tendency to polymerise because of high content (5-25 %) of the monoterpene β-myrcene in the oil, thus deteriorating the quality of the oil 1 . This oil has been the subject of several studies by many researchers from different countries [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] . According to a recent review a total of 158 compounds were identified in this oil by several research groups from different countries 2 .…”

Effects of storage time on the antimicrobial activities and composition of lemon grass oil

“…Irrespective of these factors however, most reports of chemical compositions indicated that the oil consists mainly of citral, a mixture of two stereoisomeric monoterpene aldehydes. This is particularly the case in most reports of oil composition from Nigeria (Onawunmi et al, 1984;Adeleke et al, 2001;Owolabi et al, 2008). In this wise, citral has remained the key compound in evaluating the quality of LGO (Onawunmi, 1989;Bassolé et al, 2011).…”

Variação dos teores de constituintes voláteis de Cymbopogon citratus (DC) Staf, Poaceae, coletados em diferentes regiões do Estado de São Paulo

“…No originário de Marrocos, os principais constituintes encontrados foram geranial (39,8%) e neral (32%) (Il Idrissi et al, 1993), enquanto que naqueles originários da Zâmbia e do Zimbabue foram encontrados geranial, neral e mirceno em diferentes proporções porém com expressiva predominância dos dois primeiros (Chisowa et al, 1998;Chagonda et al, 2000). No óleo essencial de uma amostra da Nigéria foram encontrados geranial (40,9%), neral (29,7%), mirceno (11,3%), linalool (1,7%) e acetato de geranila (1,6%) (Owolabi et al, 2008).…”
