The article provides a thorough overview of the extraction methods, properties, compositions, and industrial applications of lemongrass essential oil. Traditionally, lemongrass (Cymbopogon Citratus) essential oil has been utilized for centuries in medicine to enhance blood circulation, treat fevers and malaria, aid digestion, and boost the immune system. Lemongrass essential oil finds extensive use across various industries, including aromatherapy, food and beverage, pharmaceuticals, fragrance and flavor, agriculture and livestock, cosmetics and soaps, as well as household products. The quality of lemongrass essential oil is significantly influenced by the extraction method and the conditions under which it is obtained. Various extraction techniques can be employed to obtain lemongrass essential oil, such as steam distillation, Soxhlet extraction, ultrasound-assisted extraction (UAE), hydrodistillation (HD), microwave-assisted hydrodistillation (MAHD), and supercritical fluid extraction (SFE) using carbon dioxide. The Key physicochemical properties of lemongrass oil include specific gravity, optical rotation, refractive index, citral content, freezing point, moisture content, acid value, ester value, carbonyl value, and phenol content. It is important to note that the chemical composition of lemongrass essential oil can vary based on factors such as geographical location, cultivation methods, plant age, photoperiod, harvest time, cultivars, and extraction techniques. To address the limitations of traditional distillation methods, environmentally friendly extraction technologies like supercritical fluid extraction (SFE), steam distillation extraction (SDE) and microwave-assisted hydrodistillation (MAHD) should be considered for industrial-scale production of lemongrass oil.
