1.ABSTRACT

Three methods are used for oil extraction namely solvent extraction, hydro distillation and enfleurage. Distillation based recovery processes such as steam and vacuum distillation are preferred for the extraction of essential oils from plant materials. Essential oils are very complex in their chemical nature. Fragrance extraction refers to the extraction of aromatic compounds from raw materials and using methods such as distillation, solvent extraction, expression or enfleurage. All of these techniques tend to distort the odor of the aromatic compounds obtain from raw materials. Heat, chemical solvents or exposure to oxygen in the extraction process denature the aromatic compounds either changing their odor character or rendering them odorless. Before perfumes can be composed the odorants used in various perfume compositions must first be obtained. Synthetic odorants are produced through organic synthesis and purified. Odorants from natural sources require the use of various methods to extract the aromatics from the raw materials. Properties for lemon grass oil are color - pale yellow to orange yellow, density – 0.872-8.897 at 20 oC, Refractive Index – 1.48-1.50 at 20 oC, viscosity – 4.45 cSt. 6.4.5 and pH – 4-5. The % yield of lemongrass oil extracted using hydro distillation process where water use as a solvent. The maximum yield of lemongrass oil is 2.2 % since the lemongrass contains the 2.5 % max. oil by weight. Experimental analysis carried out at various feed to solvent ratio and various extraction time in hrs. For various feed to solvent ration 1:5 and 1:7.5 shows the % yield 2 and 2.2 resp.  with extraction time 3 hrs. and % recovery 80 and 88 % resp.
