Due to the numerous benefits of essential oil, its demand is increasing globally. Despite this, one of the challenges involved with the essential oil extraction from lemongrass is the low oil yield, the current work investigated the effect of operating parameters contact time (1-5 h), particle size (0.5-2.5 cm) and volume (100-300 ml) on the yield of essential oil from lemongrass (Cymbopogon citratus) using Soxhlet extraction to determine the best operating conditions resulting in highest oil yield. The results show that as the particle size increased from 0.5cm to 2.5cm, the yield of lemongrass oil decreased from 1.62 to 1.225%. Conversely, as the contact time and solvent volume increase, the oil yield also increases. Considering the results from different operating parameters, contact time imparted much on the oil yield, and the maximum yield of lemongrass oil is 1.7% obtained using 100g of dried lemongrass, particle size of 0.5cm and contact time of 5hr. This information will serve as important resources to the essential oil industry.
