The essential oil is extracted from lemongrass stem and eucalyptus leaves using hydro distillation method by Clevenger apparatus. The effects of main operating parameters were studied: time to reach equilibrium, temperature (95 to130°C) and particle size (0.5 to 2.5 cm) of the fresh stem and leaves, to find the best processing conditions for achieving maximum oil yield. We have performed extraction process on two types of samples dry sample and wet sample of both grasses. After the experimental analysis we observed that the yield of wet sample is much greater than the yield of dry sample. And we also observed that the oil content in lemongrass stem is more than the eucalyptus leaves. The results showed that the temperature 130° C of the raw material of particle size 0.5 cm for 180 minutes give the highest percentage of oil (29 %). The extracted oil was examined by GC-MS. Key Words : Essential Oils, Eucalyptus Leaves, Hydro distillation, Lemongrass , Optimization. 1. INTRODUCTION 1.1 Lemongrass Lemon grass (Cymbogen citratus) is found in many parts of world. It is mainly grown as an ornamental plant however lemongrass has many other uses such as a food crop eg. It is used in herbal tea because of its sharp lemon flavor. It is used as the perfume in soaps and a medicine to treat various health ailments, decreasing acne, athlete’s foot, flatulence, muscles aches and scabies. Further, bioactivity studies have shown that the various components of this ingredient oil contains antimicrobial, antifungal, antibacterial and mosquito repellent properties make it a valuable product to be extracted. The citral isolated from oil is used in the manufacturing of vitamin A, Because of those attributes lemon grass is of great use and value in the agriculture sector, especially for the protection of stored agricultural product. Crude essential oils are obtained by steam distillation of variety of natural products like plants, grasses, wood stumps saw dust, flowers, kernel and social hygiene of mankind in terms of their use in cosmetics, toiletries, medicinal formulations, aroma therapy, surface coatings etc. Most of the essential or ingredient oil occurring in nature consists of mixture of hydrocarbons like terpens, sequiterpenes, oxygenated compounds like alcohol esters, ether, aldehydes, ketones, lactones, phenols and waxes. Out of these oxygenated compounds like alcohols are the principal odour carriers. They are more stable against oxidation agents. The

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
