A comparison of essential oil extraction from the leaves of lemongrass (Cymbopogon nardus L.) using two microwave-assisted methods

The extraction of essential oils from Lemongrass leaves (Cymbopogon nardus L.) has become more promising than ever before due to the oils' increasing demand in market addition dynamic breakthrough its technology advancement. This study presents a comparison two different methods microwave-assisted oil extraction, namely Microwave Hydrodistillation (MHD) and Solvent-Free Extraction (SFME), both which exhibit better quality terms recovery compared conventional methods. investigated effect time, microwave power, as well feed-to-distiller volume ratio (F/D). Experimental results suggest that although there is tendency increase yield along with turns out decrease at higher optimum power for MHD method being 420 W SFME 560 W. Smaller F/D ratios appear give yields smaller size material, obtained. produces but citronella method. Two first-order second-order kinetics models were methods, model was slightly representing experimental data based on RMSD R2 values. applies using respectively.
