The distinctive aroma of lemongrass is the property of citronellal which dominates the metabolome. Essential oil can also inhibit the growth of various Gram-positive and Gram-negative pathogens in humans including Acinetobacter baumanii, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella typhimurium, Serratia marcescens and Staphylococcus aureus at concentrations of 1200 µg/ml up to 20000 µg/ml.
Citronellal (3,7-dimethyloct-6-en-1-al) is an active compound to repel mosquitoes. Other active compounds which are also responsible for this property are citronellol, α-pinene and limonene.
Citral can also be used as a precursor for the synthesis of B-ionine which is used in the synthesis of other aromatic compounds, vitamin A, vitamin E, carotenoids and other pharmaceutical products.
