Essential oil content in lemongrass

Lemongrass is an herb that belongs to the genus Cymbopogon of aromatic grasses and contains essential oil with fine lemon flavour. Generally, three species are identified:
*Cymbopogon flexuosus
*C.flexuosus var.flexuosus
*C.flexuosus var. albescens

Lemongrass present lemony characteristic flavor due to its main content, citral which present great importance to the industry. Citral, a combination of neral and geranial isomers, is used as a raw material for the production of ionone, vitamin A and beta-carotene. Lemongrass oil contains citral at concentrations of approximately 65-85% w/w.
Essential oils are natural products obtained from plants. They were formed by varied and complex volatile mixtures of chemical compounds, with predominance of terpene associated to aldehyde, alcohols and ketone which were deposited in various structure of the plant.

Essential oil and citral of lemongrass were detected to gather at parenchyma tissue cells, specifically in the adaxial surface of leaf mesophyll.

Lemongrass is commonly used in Asian cooking. When Thai food was embraced in the US, lemongrass became a household name. Alittle experimentation with this delightfully fragrant herb is all it takes to realize that it can be used in many more ways than just in Asian dishes. A simple syrup made by steeping lemongrass in a mix of equal parts hot water and sugar can be used to enhance fruit salads or to make home made soda by mixing it with seltzer.
