Due to the medicinal value of Lemongrass oil, it is widely extracted from lemongrass using a separation technique. With this method, lemongrass oil is obtained as distillate preserving the natural qualities of the plant. Distillation consisting of the steps boiling, condensing and decantation is taken up on a laboratory scale. Gas Chromatography (GC) is employed to analyse the lemon grass oil, to evaluate oil for its ‘citrals’ content (Gernial and Neral) qualitatively and quantitatively. The vapours emanating out of distillation are condensed to obtain a two phase system of oil and water, which is further decanted. The present paper discusses the variations in yield and specific steam consumption with respect to density of grass in the distillation flask. Also, the kinetics of extraction was studied.
