INTRODUCTION: Lemon grass is a tall, fragrant, lasting plant having History huge striped leaves with a lopsided edge. It is Lemon grass, a lasting plant usually developed in broadly known for its smoky, sweet, herbaceous the sub-tropics and tropics, assigns two distinct and lemony aroma. It has a place with variety species, West Indian, Cymbopogon citrates and Cymbopogon, family Poaceae [1]. It contains East Indian, Cymbopogon flexuosus. It is called as fundamental oils with a fine lemon enhance. It is the tropical Asia East Indian lemon grass on the utilized as narcotics in India [2]. The basic oils grounds that different types of the lemon grass are acquired is portrayed by a few monoterpene local toward the South East Asia, South Asia and constituents, ex. Limonene, citral, elemol, Australia (Sri Lanka, India, Thailand and Burma) citronellal, 1, 8-cineole, citronellol, linalool, (Cymbopogon flexuosus) otherwise called the geraniol, methylheptenone, b-carophyllene, Cochin or Malabar grass and for the related West geranylformate and geranyl acetic acid derivative. Indian lemon grass (Cymbopogon citratus) [15]. In GC-MS is commonly utilized for the compound 17th century, lemon grass was being distilled for portrayal of the basic oils [3-5]. In a few species of export. At world’s fair at London crystal place in Cymbopogon, citral (geranial and neural isomers) is 1951, the first samples of closely related citronella one of the significant chemical constituents of the oil were displayed. It is favourite oil in India for oil having its uses in confectionery, perfumery and many years and is known locally as “choomana crude material for vitamin A (source for production polu” which refers to the plant red grass stem [16]. of beta carotene) [6]. It is generally utilized in The lemongrass is monetarily developed in the Asian (curries, teas, soups, poultry, fish and fish) India, Guatemala, Paraguay, and the People's and Thai cooking in blend with chile peppers, Republic of China, Sri Lanka, England and garlic and cilantro. In tropical nations this different pieces of Africa, Indochina, South lemongrass herb (Cymbopogon) is generally America and Central America. Lemon grass a utilized as a wellspring of medication [7]. In Brazil, medicinal plant has been considered as an insect the plant leaves are utilized as analgesic, repellent and carminative. West Indian lemongrass antipyretic, spasmolytic, tranquilizer, anti- is accounted for to have solid antimicrobial activity inflammatory and diuretic. Due to its genetic additionally goes about as a focal sensory system diversity, habitat and the agronomic treatment of depressant.

It is also used over various pathogenic unpredictable oils additionally have some fungi due to its antimicrobial actions [9]. The plant mutagenic and pesticidal activity. Cymbopogon is local to tropical Asia and now-a-days has nardus is a wellspring of citronella oil. Lemongrass become around the world. The Latin and African has been generally accepted as safe plant nations expend the herb generally. Additionally, the extract/essential oil for the human consumption. It herb is utilized in the society meds for treatment of is one of the most versatile plants. It produces stomach related clutters, diabetes, anxious delicious herbal tea, which is often used in cooking confusion, irritation and fever [10].

The chemotypes from this variety have been utilized as biomarkers Unranked Angiosperms for their identification and classification [12].

It develops in the sub-tropical and tropical locales Unranked of the world because of its wide uses in beauty care Order products, nourishment, pharmaceutical, and agribusiness and flavour enterprises. The high Family Poaceae aldehyde substance of the Cymbopogon is Subfamily answerable for its lemony scent [13]. Other than citral (more than about 75%), geranyl acetic acid Tribe Andropogoneae derivative, geraniol and monoterpene olefins are Subtribe Andropogoneae likewise present in limited quantity [14]. It is likewise utilized as an enhancing operator in Genus Cymbopogon different nourishment items.

Also, a large amount of solvent liquid extraction.

As the extraction is containers and should be placed in a water bath at carried out at the boiling temperatures of the 70-80℃ to remove the ethanol leaving behind pure solvents used, this may result in thermal essential oil. This method is suitable for the plant decomposition of the extracted materials.

To this distilled water should be added Desirable compounds can be extracted leaving (about 250 ml approx.).

The contents in the RBF are carbon dioxide (CO2) is used as a solvent in SFE as heated at a low temperature to just make water it is non-flammable, noncorrosive, inexpensive, and boiling. As the water starts boiling the steam has generally recognized as safe (GRAS) status. It generated into the flask release these volatile also minimizes the potential of isomerization and aromatic molecules from the plant materials. These hydrolysis during the extraction, due to low escaped molecules then evaporate with the steam extraction temperatures (generally less than 100℃) which travels to the condenser, where the and since water is not used during the extraction temperature is controlled by passing water at RT process. Other advantages of this method are, counter currently through it. Further, these vapours increased diffusion coefficient and low viscosity, condense and are collected in a receiver which is lack of surface tension allowing for rapid diffusion, maintained at a low temperature with the help of an and lack of chemical residue. This method is a ice bath to prevent the evaporation of the volatile powerful technique in the field of separation molecules. Further, this water-oil mixture is technology. It produces the products with a high transferred in to a separating funnel and on the value added as the process operates at low basis of the difference in the densities of oil and temperatures and prevents contamination of the water oil is separated from water and stored in a extracts from solvents. This prevents the thermal tightly closed container. This process can also be decomposition of the extracts as the process is carried by using only steam. This method is used carried out at low temperatures and also has a high widely and is also economical as it does not require product recovery.
