Introduction: A number of plant species, including Cymbopogon schoenanthus, are traditionally used for the treatment of various diseases.
C.
schoenanthus is currently, traded in the Saudi markets, and thought to have medicinal value.
This study aimed at investigating the biological activities of C.
schoenanthus against both Gram-positive and Gram-negative bacteria and to identify its chemical ingredients.
Materials and methods: The inhibitory effects of water extracts of C.
schoenanthus essential oils were evaluated against ten isolates of both Gram-positive and Gram-negative bacteria using the agar well diffusion and dilution methods.
The minimum inhibitory concentration (MIC) was assayed using the Broth microdilution test on five of the ten isolates.
The death rates were determined by the time kill assay, done according to the Clinical Laboratory Standards Institute (CLSI) guidelines.
The chemical composition of the essential oils of the plant was performed using GC/MS.
Results: The C.
schoenanthus essential oil was effective against Escherichia coli, Staphylococcus aureus, methicillin-sensitive (MSSA) S.
aureus (MRSA) and Klebsiella pneumoniae.
The essential oil was not effective against Staphylococcus saprophyticus at the highest concentration applied of >150 lg/ml.
The MIC values were as follows: 9.37 lg/ml for E.
coli 4.69 lg/ml for S.
aureus (MRSA), 2.34 mg/ml for MSSA and 2.34 lg/ml for K.
pneumoniae.
The time-kill assay indicated that there was a sharp time dependent decline in K.
pneumoniae counts in the presence of the oil.
This is in contrast to a gradual decline in the case of S.
aureus under the same conditions.
The eight major components of the essential oil were: piperitone (14.6%), cyclohexanemethanol (11.6%), belemene (11.6%), a-eudesmol (11.5%), elemol (10.8%), b-eudesmol (8.5%), 2-naphthalenemethanol (7.1%) and c-eudesmol (4.2%).
Conclusion: The results of the present study provide a scientific validation for the traditional use of C.
schoenanthus as an antibacterial agent.
Future work is needed to investigate and explore its application in the environmental and medical fields.
In addition, to evaluating the efficacy of the individual ingredients separately to better understand the underlying mechanism.
